I recently heard someone ask, “will taking vitamin make me gain weight?”. I never really considered a connection between vitamins and weight gain, so I decided to investigate the subject and do some research.
I found that daily multivitamins may be recommended for weight gain for people who are underweight, not overweight! I think some overweight people may have overheard the words, “weight gain” and “vitamins”, and come to the conclusion that their multivitamin was making them fat…
Apparently, lack of vitamins in some people may make it hard for them to gain weight, and starting to take these vitamins helps weight gain (this is what I have read online, I don’t know how scientifically accurate it is). Online, I did read about a few firsthand experiences of people gaining a few pounds after starting their vitamin supplements, so I definitely think there is some truth to vitamins and gaining weight.
So, if you are overweight, and are asking “will my vitamins make me gain weight?”, the answer is no. Its perfectly safe to continue taking supplements, or begin taking supplement, when you are trying to lose weight.
You don’t need to worry about losing weight while taking a multivitamin, unless of course you are underweight… But I highly doubt that any of us are, so happy vitamin supplement taking!

Thanks for researching this. I never really thought about this topic.

I knew it. Thank-you so much for posting this. I consider myself to be normal weight or on the low end of it anyway. Def. not underweight. Every single time I take vitamins I gain 2 pounds within what seems like days. This is not to say it stops there?? When I stop taking vitamins, I loose the weight back off. As long as I am taking vitamins, I can not loose an ounce, even when I’m biking a lot, watching what I eat, nothing. Now to figure out what to do about it. I know I need the vitamins, but who wants to watch their weight keep climbing?

Thank you barrywife. I struggled for almost a year to lose weight I went from 270 down to 215 in about 7 months, yes I am proud of myself. but then I felt as if i needed vitamins when I got to that weight and started hiking, biking and walking so I took multivitamins and in less than two months I have gained 10-15 pounds back yet none of my eating or excersize habits have changed so I will stop the vitamins and see what happens from there. But what you said makes perfect sense. I still need to get to 180 doctors orders imagine when I went in to see him with the weight gain he was not happy. Thank you for the heads up. Rick

This is not true. Zinc causes weight gain.

I am 65 and the only times in my life that I gained weight was when I happen to be taken vitamins. So for me there will be no vitamins.

lately about 1 month ago, i have start consuming the double x vitamins by Amway, and i start to find that my intake of food has increased as a result of consuming the multivitamins. I take only take once of the pills ie multivit, minerals and concerntrated vitamins. The effect of taking, my i tend to be be hungry more therefore eating more. Is it true that taking vitamin can bring to weight gain?

I had gastic bypass a number of years ago and have been maintaing my weight pretty well. Well about 2 weeks ago I started a liquid multivitamin, mulitmineral liquid vitamin and i gained over 15 lbs and my stomach is sticking straight out for the first time. I do not have an appetite and I am miserable. I think I will have to check with a doctor on this one.
9 Daniel // Aug 27, 2010 at 1:18 am
After reading these comments I dont think I will take my multivitamins anymore cause im afraid that they will prevent me from losing weight when excersising.
10 Daniel // Aug 27, 2010 at 1:22 am
Also I noticed that when I take my multivitamins I feel so full that it feels that I just ate 3 slices of pizza.
11 Ann Marie // Sep 14, 2010 at 2:19 pm
I was a normal weight my whole life. Back in March I started taking a multivitamin because I was sick of having stringly lifeless hair. By April I had put on 20 pounds and my diet hadn’t changed one bit! In June we moved and I was still 20 pounds heavier. I started working out 2 hours a day at the end of June. It is now September. I don’t drink anything but water, I’ve cut out refined sugars from my diet, I lift weights and I restrict carbs. I HAVEN’T LOST A SINGLE POUND!! My blood levels are all perfect! The only thing I haven’t changed?? Taking that stupid multivitamin! Starting today I am no longer taking it. I will continue to work out two hours a day and eat right. I am convinced it’s the multi-vitamin causing this weight gain!
12 jes28 // Nov 30, 2010 at 11:50 pm
science seems to be lacking, but every time I go back to taking a multi-vitamin, I gain a few pounds!
I don’t think it’s water retention, but it might be?
Or my metabolism slows down from the pill?
anyway, there seems to be a connection!
13 Dr Karthik Raj // Dec 29, 2010 at 2:51 am
I have observed in a number of overweight, borderline obese and obese people, a significant and a sudden burst of weight gain on taking vitamin pills. This is an excellent randomised group with representation from different age groups, social and physical history and with different vitamin manufacturers. From the data i can only infer that vitamin help siginificantly in the uptake of fat and this poses a serious problem for overweight people. Since doctors and nutritionist prescribe altered diets, we tend to add multi-vits to compensate the nutritional intake. I think this take on vitamin replacement should be revisited.
14 renea22 // Jan 10, 2011 at 11:09 pm
I did a search on weight gain from vitamins to see if what I thought was happening to me was actually plausible or if I was just attributing my sudden weight gain to the wrong thing. It seems from reading the comments that my assumptions may actually be founded in some truth. I started taking a multi-vitamin pack about a week ago, and have since felt continually bloated and have gained about three pounds. Shocking to me, since I am very active and have a pretty high metabolism.
15 sperkins // Jan 13, 2011 at 1:28 am
I’m glad to read this. I was at a comfortable weight and then decided to take a multi vitamin. Within a week I gained 3 pounds. I guess I won’t be taking my multi vitamin any more.
16 Jeanne // Feb 4, 2011 at 1:38 am
I’m not nuts!!!! I am so happy to hear other people feel this too!!! Just going to stick with by Vit D supplement and forget the rest!!!
17 Ayesha SH // Feb 9, 2011 at 8:49 pm
I am so relieved to read that there is a connection between taking multi-vitamins and weight gain. I am 5’5″ and I weighed 119 pounds 4 months back. Today I weight 131 pounds. I started taking chelated vitamins to improve the health of my hair and with that I increased my protein intake. I noticed a sudden increase in my weight. I doubled my work-out regimen 3 months back. But I have not lost a single pound. I guess my mother was right all along. I am going off these chelated vitamins. Thank you guys for sharing!!
18 Chez // Feb 10, 2011 at 9:18 am
Thanks goodness we have the internet so we can search for others who have the same questions we have. I too have battled weight for some time and looking back it seems to tie in with taking vitamins. I will go off them for a while and see what happens.
19 seflorida // Feb 15, 2011 at 4:18 pm
I knew it! I started taking Biotin and vitamin C & E about one month ago and stacked on an unheard of 10 pounds. I have a slim build, high metabolism and normally eat whatever and never gain a pound. I know have nothing to wear! I’m wondering, after taking the vitamins will the weight come off??? Thanks!
20 snwflak56 // Mar 1, 2011 at 6:46 pm
I am so happy I am not the only one with these same questions. I am 5′ 4″ and 120 lbs. I do not feel that I am over weight but I started taking vitamins to help boost my metabolism and increase my energy. I have been working out more and I cannot lose anything! It is s frustrating when I would step on the scale and I was always around 117 and 118 lbs! I think I will stop taking them and see what happens!
21 wondering2 // Mar 4, 2011 at 3:15 pm
I have also noticed a weight gain, but hadn’t thought about the vitamins that I have been taking. My question is for those that gained weight, then stopped the vitamins: Did you lose the weight that you had gained?
22 Fran // Mar 5, 2011 at 12:39 pm
I’m sorry – but I have to disagree with you. I can tell you first hand, that (for me) taking vitamins definitley makes me gain weight. I have tried several brands , multiple times and they all do the same thing – cause me to gain weight. I am trying to lose weight (i’m about 20 lbs more than I should be)….and taking vitamins doesnt help my diet.
23 lizzy // Mar 19, 2011 at 8:09 am
I woke this morning with the idea of researching this question on the internet. I have been baffled with my 3lb weight gain that has coincided with 2 weeks of taking multi vitamin tablet. Nothing else in my diet has changed. I can’t believe how many have had the same experience. Definitely going to ditch them now.
24 me too // Mar 27, 2011 at 1:27 pm
I have had the same problem with vitamins and weight gain, up to nearly 10 lbs in a few weeks. Have had this issue happen a couple times now. Last few months, I increased my vitamin C levels to 3-5 grams per day (most often people take about 1 gram or less) and my TOM cycle lengthened suddenly to 45 days. Started to research on it and found out that vitamin C and possibly other vitamins causes high estrogen levels. High estrogen causes weight gain from what I saw. So when I found out, I was already on my 34th day on my cycle, so I dropped the C. Got my period the next day. So now I’m going to reduce my other vitamins as well (but slowly, particularly on the B vitamins). Hopefully the weight will come off and hormones will be back to normal again.
25 Viper6 // Apr 5, 2011 at 5:50 am
I have stop taking multi vitamins for about 6 months now and I noticed I lost my popup belly. I am 30 year old guy 5’7″ 165 lb. I have been working out since high school and haven’t stop’d. But I noticed when ever I take multi vitamins I start to gain weight on my belly. So after some research and the findings I have stop’d taking them. But I do take omega 3 fish oil and mind power Rx of my brain. It’s working great, I lost the weight I gained and feel great. Try it and see if it works for you.

I WANT TO GAIN FAT IN MY BODY…IM 19 YEARS OLD AND MY KILOS IS 34 THEN I TAKE A VITAMINS BUT DOESNT EFFECT IN MY BODY..WHAT SHOULD I TAKE?IM GIRL…
27 IcyBlue // Apr 24, 2011 at 5:56 am
I started to gain weight in Nov. of last year, after my Dr. told me to start taking a multivitamin and Fish Oil. Since Nov. I have gain 15 pounds. My heart Dr. was very up set with me last mo. I asked him about my pot belly and he said I was just fat, and I was eating the wrong food. I’m so glad to read that other people is having the same problem with multivitamin. I know Its a connection. I have took my last pill tonight.
28 Brewnz // Apr 27, 2011 at 12:04 am
I began moderate bike riding again in January (30+ miles/week) and started taking a multivitamin and fish oil to avoid getting sick (since it’s so cold). I put on 10 lbs in spite of rigorous biking and working out in the gym twice a week. I stopped taking the multivitamin last week and dropped 5 lbs. I think this connection needs to be revisited. (Note: I don’t need to add weight if I plan to ride long distances)
29 Maxine Dodge // Apr 27, 2011 at 3:50 pm
I have always been overweight, and lethargic. I would start a vitamin routine to gain more energy, so I would be more active, but it never seemed to produce the result I was looking for. My energy didn’t seem to increase and I found I was hungrier than before the vitamins. Doctors told me there was no such correlation, I was just looking for an excuse. How many years did I beat myself up, for thinking this. THANK-YOU , it is not” all in my head”!!!
30 Felicia // May 8, 2011 at 5:36 am
Oh my I knew it had to be the multivitamin and when it is in liquied form you gain weigh even faster I have gained at least 20 pounds since taking mulitivitamins. That’s it no more because we all know weight gain makes us look older and it is unhealthy, although the fat may be healthy it is unsightly, however the remedy is probably if you take mulitvitamins you have to be on a low carb calorie diet something the makers of these products refuse to suggest.
31 Pearl // May 10, 2011 at 1:30 pm
I am getting fat and feel heavier. I began taking multivitamins three months ago and have gained 4kgs. I eat my lean protein and greens………for crying out loud i do that TAEBO and i am still not ripped!!No more multivitafattening for me period!!
32 Michele // May 31, 2011 at 2:42 am
I am so glad to read these comments. I have taken multi vitamins for years. I have also gained a lot of weight. It seems to be a lot of water weight. I noticed in the last week or so my stomach felt bloated for hours after taking my multi vitamin. I tried taking it with different foods and different times. Nothing helped. So I stopped taking it two days ago. I already feel better. I already feel lighter. I have been getting rid of a lot of water weight. I am going to try to stay off of it and see what happens. I am going to try to get my needed nutrients from my food. Thank you for sharing your stories. I thought I was losing my mind.
33 Rachelle // Jun 2, 2011 at 10:59 pm
I started taking a few vitamin about 5 months ago: minimum 4G of vitamin c everyday, vit b12, and magnesium. I normally weight around 127 lbs for 5″10 effortlessly, that means i eat what i want and never gained weight. I have gained 13 pounds since then, my jeans don’t fit! i have dieted, and worked out and it seems the scale is stuck. Some people say that vitamins can not make you gain weight because they don’t have calories, maybe they change the metabolism. i am going to stop them for 2 weeks and see what happens.
34 Natalie // Jun 4, 2011 at 10:34 am
Can someone tell me if I will gain weight with Hair Food Vitamins from Holland & Barrett? As they have buking agent in the ingredients???
I really need some hair food but am trying to lose weight so dont want to defeat the object by taking these if they will make me gain weight!
35 Roopali // Jun 16, 2011 at 10:15 pm
Thankyou all for sharing your experiences as they are no different to mines.I was gradually gaining weight and never connected it to the skin/nails/hair tablet I was taking though my hair had grown long and strong but then who needs the extra weight.Now I have stopped taking the tablet and will see how it effects the weight.
36 Richard // Jun 18, 2011 at 6:31 am
I took Multivitamins, and B12, B6, St. Johns Wort, HTP-5, daily sometimes 2 times a day, and i gained over 15 pounds fast, and my enzyme level of my liver skyrocketed, be careful with vitamins!!! Im not taking anymore!!! back to normal, my doctor said they are for people with a deficiency and i dont have that so it just adds weight….glad to see the comments…thanks..
37 norma parkin // Jun 19, 2011 at 12:36 pm

I use to weigh 120 pds I began to take vitamins when I was 32 i was in a 3/4 pants size now I am in a 8/9 sometimes 10/11. I do beleive that vitamins do help you to gain weight because it feeds the blood as if you were eating or have eaten. Yes Yes go Vitamins. I am the perfect weight now 150 pds.
39 Linda // Jul 30, 2011 at 2:39 pm
What about calcium & vitamin D for postmenopausal women which are necessary to avoid osteoperosis? Is there any correalation between these & weight gain?
40 Kim // Sep 25, 2011 at 10:18 am
OMG I wish I had read this earlier, I have been taking multi vitamins since I gave up smoking 3 months ago, and I have gained weight all around my belly area. I am walking on average 7kms a day, plus I do sit ups, I only eat healthy foods and snacks, yet the weight gain has continued. Starting tomorrow, no more multi vitmains, I will continue with my fish oil, kelp and vit a, but that is it. I will post again in 3 months hopefully with the good news that I have lost the weight that I gained from these silly pills.
41 Mary // Sep 28, 2011 at 6:07 pm
I HAVE BEEN BATTLING THE WIGHT FOR YEARS NOW & I TOO HAVE GAINED WEIGHT WHILE TAKING VITAMINS. THIS POST IS PARTLY TRUE, SO ARE THE COMMENTS. FIRST OF ALL, VITAMINS HELP YOUR BODY WORK BETTER/PROPERLY, MEANING FOOD GETS ABSORBED MORE EFFICIENTLY. SO IF YOU TAKE VITAMINS, YOUR METABO. GOES UP, YOU TEND TO EAT A LITTLE MORE (MOST DONT NOTICE), AND YOUR BODY ABSORBS MORE FAT TOO. THAT IS WHY ONE GAINS WEIGHT.
MANY PEOPLE DONT NEED ALL THE NUTRIENTS IN A MULTIVITAMIN. I FOUND THAT IF YOU GET A BLOOD TEST TO DETERMINE WHAT MINERALS ARE A LITTLE LOWER & ONLY TAKE THOSE SUPPLEMENTS, YOU DONT GAIN WEIGHT. SINCE YOUR ONLY TAKING WHAT YOUR BODY NEEDS. MULTIVITAMINS ARE GOOD FOR CHILDREN & PEOPLE THAT DONT EAT RIGHT OR DONT HAVE TIME TO EAT ON A REGULAR SCHEDULE. THEIR BODIES TEND TO BE LOWER ON MOST MINERALS, SO THEY HIGHLY BENEFIT FROM THEM. I HOPE THIS HELPS.
42 chrismichael // Oct 5, 2011 at 10:05 pm
I have to agree with mary I think everyone’s bodies are different some of us need more than a certain vitamin than others I’ve been taking these GNC men’s multivitamins and have gained some weight back after loosing the weight neither has my diet or routine excercise has stopped. I honestly think they should have custom made vitamins for each person to fit what they need an idea to think about
43 emthomas10 // Oct 8, 2011 at 2:26 am
I started working out regularly 2 weeks ago along with vitamins every day. I’ve been taking a b complex, vitamin E, biotin, and green tea extract. I feel as if I’ve gained weight, but not fat. My stomach just seems to be constantly bloated. I agree with everyone else. I’ll stop taking them for a few days and see if I lose weight.
44 Teresa // Nov 1, 2011 at 4:51 pm
I am also a Weight Watchers member who had lost 30 pounds. At the time I started the WW program I started taking a multivitamin. For the past year of so I began taking more vitamins, B6, B12, D, E. Over the past year or so I have gained some of the weight back. I work out regularly and this past Summer I even increased my exercise..the gym 2 to 3 days a week, and I began walking 3 to 4 days a week, at a fast pace, some days as many as 9 miles, and never less than 5. Still continued with my WW plan, but I did not lose even one single pound! Talk about discouraging. For the past several days I have quit taking the multivitamins and most of the other vitamins. Over the past couple of days, my weight has begun to go down….FINALLY! I am going to stay off the vitamins for a while and see if I can lose again.

I am currently trying to get pregnant with my second. I am 5’7 and have been at a constant 117 my whole life. I had a miscarriage 7 months ago and started taking prenatels, b vit, calc, vit-d, royal jelly…I am the heaviest that i have ever been!!!! I wighted this evening (i normally weigh when i first wake up) and I am at 134! this weight gain is from the last 5 months. i fit in NONT of my clothes and have blamed it on the vitamins. Family, friends, even my dr laugh at me when i say that it is the vit. So i am not taking them anymore–i will work this weight off and see how true i am! i am happy that others are saying the same thing!! i am not a crazy woman!!!! keep me updated on the weight loss after stopping these!
46 Sarah // Nov 9, 2011 at 10:31 am
I started taking a multi vit recently and have put on almost 3 kg in 2 weeks! This is despite the fact I am a university athlete swimming, running and working out 15-20 hours a week. Also I have never had issues losing weight and in the past have actually found it difficult to put on muscle mass. My sport demands that I maintain a constant weight so I’m glad I found these posts and avoided a complete disaster. Thanks everyone for sharing their experiences

48 paula // Nov 14, 2011 at 9:30 pm
thanks sooo much to everyone who has shared their experience. I to have put on like 10 pds, thought there was no hope, i took my last pills today.. Good luck everyone taking the weight off! Wish me luck!!!
49 mississipgirl // Dec 12, 2011 at 8:22 pm
I have been struggling with weight gain for several years now. I am in Mean-o-pause (menopause) and it’s frustrating. I take vitamins and have for many years – makes me wonder now (after readinig all the comments) if vitamins may be part of the problem. Would love to hear from some other ladies who are going through menopause. Note: I work out (including weights) and eat pretty healthy. So, I’m not a couch potato.
50 Anna // Dec 15, 2011 at 10:31 pm
OMG!!! Finally I found other people with the same problem! My weight was 95-100 lbs, it was before I started to take multivitamins+C+B100+D. Thought it’ll help me to loose even more but NO.:,( Now I’m 110lbs! It was just a month ago since I started taking them! Was wearing jeans size “0″, now can’t put them on. Husband says -drink water etc., but I see that it’s better TO STOP TAKING THOSE VITAM! Thanks.;)
51 Wendy Hess // Dec 20, 2011 at 8:26 am
I am in Peri-Menopause and in 6 months gained 5 pounds a month and then it stopped at a 30 pound gain, i guess that is my cellular threshold, anyway i know it is water…no, i am not in denial, you can tell, my eyes are puffy, ankles and of course every other part of my body.
I was 136lbs which is good for a lady who is 5’6″
okay, so now i am 166lbs.
I dont need to tell you ladies (or Men ) what this does to a persons mind and heart.
Now, with the weight gain came the low blood sugar and anxiety/insomnia, all part of Peri, BUT there was one thing I was doing that i think made a difference, i take anywhere from 1000 to 8000 mg of Vit C a day, since i suffer from Fibromyalgia due to to Chronic Epstein Barr Virus.
It REALLY is the only thing that gives me energy and helps with the muscle pain. Only i had feeling it was making my situation worse.
I ALSO read that Vit C. ups your Estrogen levels, and when you are in Peri-Meno the last thing you want is to have more Estrogen on top of Estrogen Dominance. Soo….
For the last 2 years the weight has stayed since the whole thing began, but one month i decided to try and stay away from Vit. C and i lost 5 pounds, DOING NOTHING ELSE, just not taking the C.
The VERY next day after i got back on it, the weight started to creep back up.
I LOVE Vitamin C!!!! so ask me if i gave it up?
no.. i am addicted to it, to me it is my Natural Aspirin, WHY oh WHY must this be?
of course i can get my C from lemons and Limes, but it is NOT the same as my lovely little Vit C pill.
I stopped 2 days ago, and i lost 2 pounds, i keep telling myself it is a coincidence so i dont have to give up my drug, but i know better.
Life is for sure not fair.
I will be taking Acidolpolus for the Epstein Barr virus, but is NOT the same. Boo Hoo!
to chose between feeling a little better and being skinny!!!
Hope this helps,
Wendy.

ohhh myyy could this be the reason ive been taking a multivitamin for almost a year now im so dedicated to it for hopes that my thin hair would be better – though it didnt actually do my hair any good- ive gained so much weight ever since and i really dont even eat that much i could last a couple of days without eating and with all the work i do i forget to eat … ive been suspecting this recently this is why i started searching online for similar cases the multivitamin is the only thing regular that i take and no matter how much i exercise i dont seem to be losing any weight thou actually i used to lose weight quite easily my whole life now it seems like it never get off .. i will drop my multivitamin and see the results i hope it turns out to be the reason so now i can be relieved
53 Robert M. // Jan 11, 2012 at 6:40 am
Im a 41 year old male with diabetes. I started taking a men’s multivitamin supplement and a 1000mg of fish oil daily. In the beginning of Nov of 2011 my weight was 201 lbs. Now in January of 2012 I weigh 231 lbs. I take insulin 3x a day. I thought it was my medication. Come to find out by reading this blog my weight gain is attributed to the multivitamin I was taking. My intake for insulin has also increased. I’m going to stop taking the vitamins ASAP. Thank you all for this information.

I started vitamin b at high doses because it is supposed to help with neuropathy. I spent $50 on this cure all mixture of vitamin B’s. I weighed 108 before starting and 8 days later weigh 115. I hope I lose it as fast as I gained it. Do you think I will lose it or will I have to work at it? I have always had a high metabolism and I won’t be happy if it has changed it.
56 Wendy Hess // Jan 28, 2012 at 7:10 am
Amy,
if it was the B- Vits, then it will come off.
Was there any other Vitamins in with them?
By the way i tried B-50 for my Fibromyalgia a few years back before i knew it was an Autoimmune Disorder, thinking it would help the Carpal Tunnel etc…
and nooo, it make my hands fall asleep up to the elbow, and i was only taking 50mgs a day, i thought that only happenend (with B-6) when you go over 50mgs. Oh well, i stopped and so did the tingling.
What is causing your Neuropathy?
Did you know the Diabetes II can cause that?
not trying to scare you, just be informed.
Doesnt sound like Diabetes, since you are not of the over weight persuasion.
Weird too, you’d think the B-6 in the Multi B would make you pee.
Go figure.
I took Guiffenesin for Fibro YEARS ago, all it did was to make me retain water.
Remember, B Vitamins are water soluable, so it should leave your body sooner.
Excuse my spelling,
Wendy.
57 Myrns // Feb 27, 2012 at 12:22 pm
I have had to start taking multi-vitamins over the last 1.5 months for fibromyalgia and all of a sudden I feel like I’ve just exploded outwards
I didnt know what it was as I havent changed my eating habits, have given up smoking and taken up walking, think it might be time to cut back on them after reading this!
58 Eve // Mar 5, 2012 at 8:59 pm
Wow wow wow! I also woke up this morning thinking about why I cant lose this weight. I have always been overweight and could never lose more than 10 pounds. I changed my eating habits, became a vegetarian and upped my vitamins- thinking I was helping myself. I eat the most healthy fruits, veggies, beans, tofu and whole grains- and still cant drop the weight. I have remained this same 138 lbs for months and now I feel like there is hope. I will try to cut out the vitamins and see what comes of it. I am healthy and have no medical issues at all – so I think I can handle stopping the vitamins as an experiment. I am so hopeful this will finally help me!! Thanks everyone for the wonderful comments and validation.
59 Andres // Mar 6, 2012 at 1:43 am
Hey guys im in the same path, I did the hcg diet and got be 250 lbs, once i finished I was still in classes and felt very light headed and began to eat more to meet the needs of my studying, I gained 5 to 8 lbs. But maintained it for 2 weeks, then I decided to take my vitamins, and wala!! gain weight. But till 265, then the holidays came and I ate normal, sure a couple drinks and a bit more than usual but to weight 286 and taking vitamins oh no, now im at 303, I am now going to stop these vitamins till this Saturday as I felt good with my new herbalife multivitamins, these also have made me gain weight but really slow, and i feel better. oh yeah guys look at this logic, they say caffeine actually diminishes vitamins in our body so couldn’t that also be why we feel more energetic besides caffeine, some vitamins make me sleepy, who agrees

I have lost 19lb on Trevo since the end of December- 174 nuetraceutical, 100 percent soluble, liquid nutrition all in one bottle. I recommend any one to try this. Healthy enough for two years of age and up.

I am glad that I read these comments. I have always believed multiple vitamins correlate with weight gain. I had started a diet recently and was losing weight. Then, I got this “bright idea” to start taking a basic multiple vitamin. I even chose an organic one, thinking it would be better for my body. Eeek. Within, just a day, my appetite increased and I was starting to feel bloated. I am putting my weight back on. Needless to say, I am going to quit the vitamins.

I started a diabetic diet on Jan.3rd,2012, Under Dr.s orders, as she told me I was pre-diabetic. starting weight was 177, by 3,22,12 I was down to 149 and was walking 1 hour a day at a fast pace, and was feeling pretty good. I then started a multivitamin and have just maintained since then, cannot seem to lose right now, so this morning I decided to research the internet. Glad I found this. As since taking these I seem to want to eat more. I still have 14 lbs to lose and I intend on doin so. I have not took my vitamin this morning, so now i will stop the vitamins and see what happens, I will check back in Friday, and let you know the outcome.

I am glad to read these comments. I too gained weight while taking vitamins. They are good if you need them. Otherwise they are only good to make us gain weight.
64 Alicia // Apr 17, 2012 at 4:50 am
I am so happy to have stumbled on these comments. Through exercise and good eating, I have always been able to either maintain my desired weight or (when necessary) step up my exercise program in order to lose a few extra pounds. About 2 months ago I started taking a multi vitamin along with a variety of other supplements. I have been gaining weight, and my stomach is unusually bloated. I am going to stop taking them to see if I notice a change. I will certainly post my results.
65 Laurie // Apr 20, 2012 at 1:13 pm
I just wanted to come back and say that I did lose 3.8 lbs this week after continuing to do my regular dieting routine, and not taking the multi vitamin at all!
66 wendi // Apr 22, 2012 at 2:54 pm
I have also gained weight from taking vitamins. I could not figure why I was gaining if I did not change my routine.
67 Ilene // May 14, 2012 at 3:55 am
Never in my life have I exercised so much and gained 12 pounds almost in a matter of weeks. I have never had a weight problem, but I am the hubby both started vitamins and both gained exactly 10 pounds. He can’t take it off and neither can I. We eat very little sweets and both can’t loose this extra pounds. I can literally eat just soup and still keep on the weight. I asked a doctor about the weight gain and she said it was not the vitamins. I don’t believer her. Everyone that I have known on a several vitamins gained weight. Wish they would admit it that it does bulk you up and the bulk does not feel comfortable.
68 Barryswife // Jun 13, 2012 at 3:16 am
Just leaving an update. I wanted to add that when I take vitamins, they seem to cause me to have a hard time keeping my blood sugar up? I have hypoglycemic episodes and am not diabetic. I weigh -120 & am 5’5″ Has anyone else noticed that? For me, the weight does come right back off after stopping the vitamins. I also have noticed in the past year that milk does this too. I can drink milk for a few days and have a temporary weight gain of a few lbs. I can lay off the milk for 2 days and the weight goes away. I mention this b/c my theory is either it’s a common vitamin in both or an inflammatory process or a coincidence that causes both of these. (though milk doesn’t make my blood sugar drop)
69 wendy hess // Jun 16, 2012 at 8:23 am
Hi everyone, well i got back on the vitamin c because i was addicted to it. Since my Post in Dec. i have gone from 166 to 172! like i need that. 2 weeks ago i took 10,000 of c to do a liver flush and my period came on Day 34 i know this is not unusual in Perimenopause but too much of a coincidence! had enough? yes i have. let me stay off for as long ar as i can and see what happens. i will let you all know. also to the lady who said she Got hypoglycemia from the vits… did you know that vit B 6, vit D, and the Mineral chromnium can do this?
70 Kavita // Jun 23, 2012 at 10:41 am
I recently started taking Vitamins for Hair, Skin and Nail and noticed a weight gain of nearly a Kilo in a month! I run 5 days a week for an hour and am good with my diet but thought of taking supplements as it seemed I was experiencing hair fall. I am so glad that I came across this post as my mind was constantly baffling for the reason of weight gain when I exercise and eat well! Before taking the supplements, my weight was coming off at a steady rate. Time to ditch the pills!
71 Mohamad // Jun 30, 2012 at 12:36 am
Hi,
Thank u all for these comments. So, I am not alone; I thought I am going crazy. I gained about 5 lb in one week with a tough diet and exercise. I am sure it is related to the multivitamin I have been taking. I do not care what drs say. It is my body and i did the math. No multivitamin for me anymore.
72 Pina // Jul 10, 2012 at 9:25 pm
I tossed 6 weeks supply of multivitamins & minerals into the trash can after reading these comment. I too was exercising double time and eating like a sparrow, only to gain a few lbs. Good I stoopped taking them when I did.
73 MamaJay // Jul 20, 2012 at 9:15 pm
I had the lapband surgery done in late 2008. Lost steadly over the next few years, then leveled off last year. Then my hair started to come out, slowly, not in patches. My doctor said that comes with sudden weight loss although I never thought it was “sudden”. Then she suggested taking multi vitamins, which I started a couple of weeks ago. Now the weight is coming back on even though I have been careful about intake. Hummmm, have hair come out or gain weight!!! What choices!!! I also started using a generic Rogain from our reginalal grocery chain. Perhaps I should stop the vits and see if that would work on its own!!!
74 Debra Born // Aug 1, 2012 at 5:17 pm
Like you all I could not understand why I was putting on weight. Yesterday I was thinking about the time the weight gain came on was when I started taking a multi vitamin (2 months ago). So I decided to research today. Can’t beleive it, but I do beleive it’s the vitamins. I’m 57 and I have never had a weight gain problem like this. I’ve put on 15 lbs. I have to agree there’s to many of us with the same problem for it not to be the vitimins. No more for me. So now I’ll see what happens in the coming days. I will keep you posted. Thanks to all of you.
75 Mike H. // Aug 10, 2012 at 12:38 pm
I am having spine surgery on the 13th of Aug. After stopping all vitamin supplements on July 30th I have been losing weight. I have gone from 164 to 158 on Aug. 9th. I eat a healthy diet. No sugar,salt, no fast foods. My wife still takes the vitamins which consist of multi, D,K.biotin,lutein and chia seeds. Her weight does increase so she has to really cut back on her diet to lose weght.
76 Sher // Aug 14, 2012 at 1:28 pm
I took those GNC hair tablets for 4 days and gained 3 lbs!! I wasn’t eating more, ut i’ve heard that these supplements help you absorb fat better. Hopefully it will all come off. I’ve already lost some water weight.
77 Rhea // Aug 20, 2012 at 4:21 am
Ok, even I agree. Iv been taking vitamins for iron and hair n skin. I have been gaining weight since then. I work out 5 times a week. Always active. Being a housewife, always running around for daily chores and even then my weighing scale says a different story. I’m frustrated!
78 Nate // Sep 19, 2012 at 3:53 pm
I literally run on my elliptical for an hour and a half daily burning almost 2000 calories. I have been gaining weight and began to track my caloric intake along with my estimate of almost 5000 calories burned per day and I’m typically eating 2500 calories daily? I’m gaining weight! Now after reading the posts on this forum, I am beginning to wonder if it’s the vitamins. I am a supplement fanatic and I take CVS’s Daily Energy Multi. I’m seriously enthused by this discussion. Going to cut all supplements and will report back.
79 Sarah // Oct 2, 2012 at 3:20 am
I’m so happy to read this. I started taking Stress Relief Multivitamins last March and since I have bloated all over. My thighs especially and after eating my stomach is huge! Makes me feel pregnant. I am a healthy 22 year old 5’4, was 120 lbs, now about 135 lbs. I couldn’t figure out the weight gain since my intake of food and my daily routine have remained the same. I feel the exact same accept for a fatter body. It’s horrible! Don’t feel good in a bikini anymore. So I’m joining everyone on here, no more multi vitamins. Super appreciate all the comments
80 maria // Nov 3, 2012 at 4:44 am
I started taking prenatal vitamins 3 mos. ago since I was trying to get pregnant and wanted to prepare myself in advance. I gained 10 lbs since then even after going to the gym for 2 hrs three times a week. I’m in this site, because I won’t believe that I’m delusional to think that its the vitamins since doctors like myself has never heard anything like this before. There’s no enough evidence showing that vitamins cause weight gain. Its because vitamin companies won’t release research results or won’t even FUND a research that can harm their sales, of course! But hey, experience is the best teacher, and I think I believe that vitamins do make women gain weight!
81 miya // Nov 29, 2012 at 3:12 am
OMG i am sooooooo glad i found this webpage!!! ok so i thought i was “lacking vitamins” in my body since my hair wasn’t growing and hence i bought garden of life’s raw vitamin vode for women (1 pill a day) and also their b-complex (1 a day). so i’ve been taking both bills for about 2 weeks and i have gained ATLEAST 5 lbs!!!! my upper arms are super-chubby and im gaining weight around my belly!!!!!!! and ive NEVER had fat on my belly, i’ve always had the tightest and flattest stomach ever, even with no exercise! i *think* it has improved my hair, but im also taking fish oil (which thankfully doesn’t cause me to gain weight) but i think im totally going to ditch the vitamins. a shame too cause they were sooo expensive and hard to find
i totally wasted my time! but im not gona do anything to compromise my weight/health. perhaps i should try childrens’ vitamins rather than adult ones? all i know is im quitting all these stupid multivits from TODAY. i will come back soon (in one week) to report any changes to my weight.. and yes, like many on here, i too feel super-hungry after taking vitamins. ugh, i hate the stupid chicanery of these big pharmas.
82 LeNoir // Jan 13, 2013 at 3:53 pm
Oh so happy to have found this page…. I’m a soon to be 45 year old female and stand 6’2″. I have been taking mutil vitamins daily for 4.5 years and have gained almost 70 pounds during this time. I had gone to my doctor and was told it was my diet, hormones the fact I was getting old…pretty much everything.
I had a hystericotomy (sp?) two years ago and had lost about 30 pounds during my recovery; I thought ok things are starting to turn around, WRONG. After six months I’m back to WEIGHING 255 pounds….I have never weighed this much in my life…I know that people gain weght over the years but I have always been active. I only weighed 156 the day I gave birth to my son. I believe with all my heart that vitamins are the cause of MY weight gain. I have not taken a vitamin in a week and continue to use my treadmill and have lost 5 pounds in this time…and it’s not water weight. I’ve been using my treadmill for the past three months with no weight loss. I have choosen to eat better and ditch the vitamins.
83 kat // Jan 15, 2013 at 5:17 am
I’m 32 year-old 5’4″ female weighed between 111-114 since I had twins 6 years ago. Started taking a women’s multi vitamin two weeks ago and today my pants wouldn’t button. The scale said 119.5. Omg. I haven’t done anything different as far as eating or exercise. I have never gained weight like this in my life and eat fairly healthy. Gonna stop the vitm tmrw and pray it melts off as quickly as it went on. This is depressing ! Like the rest of you its mostly around my middle and my arms. We can’t all be crazy…there has to be a correlation .
84 Emily // Feb 14, 2013 at 11:15 pm
Like everyone here I am so glad I found this page!!
I have tried different multis and have been on and off of them & same story…I always gain weight. I thought it was because I was exercising more + my appetite increase. I have often wondered if it was my vitamin. Something wasn’t ‘right.’ I started a new vitamin about a month ago and am experiencing unexplainable weight gain yet again. So here is the test…I’m going to stop taking that damn vitamin and re post next week to see if it worked.
85 Emily // Feb 14, 2013 at 11:24 pm
Has anyone seen a change since they stopped their multi?
86 Wendy Hess // Feb 17, 2013 at 10:42 pm
Well Guys, i did NOT stop the Vitamin C as it is thought to Help the ADRENAL Fatigue Syndrome that Women go thru During Peri-Menopause. ( and as i said before , i feel addicted to it )
And I think it helps the Fibro. anyway….
I Love Vit. C, and refused to believe that it could be contributing to my weight gain, ( in Denial here )
ALL the information says that it HELPS, i understand that the Adrenals also spits out Aldosterone, the water retention hormone,
(along with Cortisol) and this is the cause of the water weight, but WHAT IF the Vit C is making it worse???
HOW can i tell? Be Strong Wendy and stay away from it for ONE Dang month, again i am going to try, for i am now 176 lbs! up 4 pounds since last year when i posted.
Okay, nothing else has changed, my eating, or activity, but i am getting MORE swollen.
I keep hoping that after Menopause the Adrenals will chill out, since they are working overtime to help at this change in life, but i am tired of waiting.
Salt is necessary for the Adrenals as well, so a low salt diet is Not good.
( but it too much makes me worse )
The run down is this, I am going through Hormonal Changes, i get that.
When after my Daughter was born i was 40 years old and already starting the “Change” my Adrenals freaked out and i gained 20 pounds in a very short period of time, then less than 2 years later, after things balanced out, i peeeed it ALL out.
Well this time is is the: THE BIG CHANGE”
so it is taking longer to recuperate.
I understand this is Hormonal, but is a REALLY big coincidence that when i take the Vit C i get more swollen.
Okay, so if the Aldosterone is causing the water retention could the Vit C be making it worse? so i looked it up and the only thing i found was that Vitamin C DEPLETION causes Aldosterone to DECREASE.
Now, we all need Vit C, so i will try to get it from fruit.
Be Strong Wendy, i say this because i have a Very Addictive Behavior, thank God it is with Vitamins and and not Drugs ( been there 20 years ago )
So allow me to obsess and try and again, perhaps, also the Scurvy theory might come into play here, in stead of moderate Vit C, i do a bunch, then stop, so maybe the Body says; “What are you doing here????”
Sorry to bore anybody,
Okay, be back later.
Wendy.
87 Wendy Hess // Feb 17, 2013 at 11:04 pm
I dont remember taking vitamin c when i was pregnant ( i am 48 years old now ) with my daughter, i did take i multi, prenatal but then stopped after she was born.
i had a Good pregnancy weight and then lost a little after she was born, but then because of the hormonal changes after the birth, and my age, i started to gain (Adrenal Fatigue), then later after the Adrenals got better, i lost, NO changes at all in lifestyle. Then a few years later the Adrenal Fatigue began again and AGAIN the weight gain, so i KNOW this is Hormonal, but HERE is the interesting thing……..Right at the Time the Adrenal Fatigue / Peri-Menopuase thing started again ( it cycles, i have heard until Menopause is finally achieved )
I started taking Vitamin C, 8 thousand mgs a day, because i found out the the Fibromyalgia i have had since i was 19 is was triggered by the Epstein Barr Virus, HENCE the want to take the Vitamin C……Only the NEXT month after taking Mega- Doses, i started to GAIN AGAIN, 30 pounds in 6 months,
so once again as in my past Posts, the Question of the Day is;
Does the Vitamin C make the Water Retention WORSE? ( that is already happening due to Hormones )
The Human Body is very complicated, so one must remember it is never just ONE thing that is happening simultaneously, so TRIAL AND ERROR is the only way.
Meaning, i cannot Change the “Change” but i can Stop the Vit C and “See” what happens.
wish me luck.
I AM I GIANT WATER BALLOON WOMAN!

88 chuck // Mar 26, 2013 at 10:38 pm
I lost 22lbs. last year and kept it off until recently,when I put 6 lbs. back on in a month. The only thing I’ve done differently is started taking a lot of vitamin C. [because I work out in the cold all day].So I googled the question ‘do vitamins cause weight gain?’ …and I think I have my answer.
89 Wendy // Mar 28, 2013 at 10:42 pm
Okay!
i have been off Vitamin C …
from Feb. 17th to Mar. 17th and lost 4 pounds.
DOING NOTHING DIFFERENT. Period.
It was hard, i craved it, i wanted it.
I am over that now, but in early March i talked myself into Taking some, because i was in Denial still as a Vitamin C addict.
I took 1500mgs and the nest day the scale went back up 2 pounds, i stopped that day and the next day, it was gone. I tried blaming it on the Chinese food, but on the days i am NOT taking Vitamin C and eat Chinese, this does not happen.
I try to get No MSG by the way.
So now we are at March 28th and no change on the Scale, still only a 4 pound loss, but i try to remind myself that this Water Retention is Due to Peri-Menopause and the Vit C just made it worse.
??? who understand these things?
Still not going back on C, getting it from Fruit.
Wendy.
90 Amber L // Mar 31, 2013 at 12:53 pm
I started taking vitamins…..gained about 15 pounds. NOT WORTH IT! I’m now making sure that I eat my correct daily “servings”.
91 Alison E. // May 1, 2013 at 3:33 pm
So glad to hear I’m not the only one battling this. Trying to get pregnant with our first and on doctors’ recommendation began taking prenatals and calcium. I was also taking a multivitamin and a probiotic that I had been taking for a while. I have gained consistently ever since and have actually been eating better and working out more regularly. Think I’ll cut out the multivitamin and the extra calcium and see what happens. Thanks for sharing yall. Nice to not feel like I’m alone / crazy in thinking vitamins could be causing my weight gain.
92 Nari // May 10, 2013 at 6:07 pm
My understanding from the article above, that vitamins and supplements to not cause weigh gain and all the comments say opposite. So, I guess miss-read the article. I’m taking Fish oil/Omega 3 for over 5 years by now and have struggle with weight since then. I guess this is the cause. Any comments re Fish oil/omega 3. Also, do you see difference between Vitamins and weight gain.. I mean, I started Vitamin B and E 2 days ago…so don’t know what to do. Need some professional and research supported advise!!!
