Reviews for Biotin

Yo-yo · Taken for less than 1 month June 23, 2019

For Dietary Supplementation: "I’m on day 1 of taking Biotin 1,000 mcg for hair loss due to thyroid disease. I am hopeful that it will work and I am encouraged by the reviews here. My hair has become extremely thin with receding patches. I will keep you updated a month from now on July 22."

Epileptic · Taken for 10 years or more June 10, 2019

For Dietary Supplementation: "After taking phenobarbital for years to control my seizures, I looked up the effects it had on my body. Hah! It depletes the biotin your body produces. I started taking biotin supplements. Really can't remember the amount it was that long ago. I am 70 and have been taking phenobarbital since I was 17. I started taking biotin supplements about 16 years ago. I had strong nails for the first time in my life. My hair is thick and wavy to curly. My skin is still in amazing condition at my age. I can't give all the credit to biotin. Pretty sure genetics played a part. No headaches. No side effects. Just a better me where I needed help. Very happy I looked it up all those years ago. Look at me... long and strong nails for the first time in my life. I was a chef, retired now, and I have nails. Never could when I was working. "

Hair, Skin & Nails (biotin) for Dietary Supplementation: "I have been taking this for over a week . I have been feeling tired and I don’t know if it’s the medicine or if I’m pregnant?"

creekgirl · Taken for 1 to 6 months September 26, 2018

For Dietary Supplementation: "I am a 70 year old white female. For a long time, my hair was getting extremely thin. I started taking Biotin 5,000 mcg once a day and after a month, saw a great improvement. I still have a rather thin place, but overall my hair is much thicker and has come in much curlier! It's also helped my husband, I can see a difference. We've had no side effects. It hasn't seemed to make any improvements in my nails, unfortunately."

Evie · Taken for 6 months to 1 year August 27, 2018

For Dietary Supplementation: "Ever since I have been taking this medicine my hair skin and nails are just so strong and looking great!"

Cin · Taken for 6 months to 1 year July 19, 2018

For Dietary Supplementation: "I'm 58 years old. This year I complained to my doctor that my nails were thin and a mess. Lots of vertical ridges and splitting for many years. He recommended Biotin. I took it a few years back without seeing any difference so I stopped. Now I thought a bigger dose may be effective. So I am trying 5000 mcg daily. Six months later, most of the ridges have gone away but my nails still are thin. My hair is seems thicker. I did not get headaches and I have always had acne, that hasn't changed."

Dee · Taken for less than 1 month May 11, 2018

For Dietary Supplementation: "I’ve had an almost constant severe headache for about a week. I go to bed with it and wake up with it and the only thing I’ve related it to has been the biotin."

Kellyjo · Taken for 2 to 5 years April 7, 2018

For Dietary Supplementation: "I have had a 100% satisfactory rate with taking biotin. my hair was all busted off to about 4 in on my head and now my hair is in the middle of my back. I have autoimmune disease, JIA and it has helped me tremendously with my health issues. I think that the people that are getting bad side effects from the it, don't need it. I need it!! my body is depleting daily of all kinds of vitamins and minerals, so as for the acne, the headaches, the menstrual cycles, all that, I've not been affected and I've been taking it for over 2 years. I recommend it to everyone that I talk to, that has thin wispy or ugly hair."

Marip · Taken for 1 to 6 months April 3, 2018

Hair, Skin & Nails (biotin) for Dietary Supplementation: "I've been taking it for over a month, with no side effects until today. Had the worst nightmare ever and I'm still not sure if it was because I took it without a meal or not. Hopefully was just a random fact and not a side effect of a hallucination."

alopeciaguy · Taken for 1 to 2 years December 10, 2017

For Dietary Supplementation: "I'm a retired male, and I've been suffering from Alopecia for years. The gal who has been cutting my hair for over 25 years would hold up the mirror and give me an update as to how many, how large and how visible the patches were each time I saw her. I tried Vitamins E, D and B, and when taking them all I had some success, but the Alopecia was still there. For some reason, I never complained about it to my primary care physician, but he noticed my brittle nails and recommended Biotin -- voila, the Alopecia disappeared! I guess I should have mentioned the Alopecia to my PCP years ago! Interestingly, I still have the brittle nails."

For Dietary Supplementation: "I am a 19 year old female. I took this to make my hair grow. I am prone to headaches and acne and thought nothing of it until I had an inescapable migraine and weird cramping in my intestines that are most likely due to this drug. My head felt cloudy and I also had trouble focusing at times. I'm trying to wean myself off and am coming to terms with the fact that my hair will grow at the pace that it wants -.-"

Amanda011504 June 20, 2017

For Dietary Supplementation: "I regrew my hair and you can too. I've been bleaching my hair on and off since forever. My hair wouldn't grow any longer it would just snap off. I've dreamed about having thick, long hair. My friend suggested Biotin when we were talking about my hair loss. I’ve tried like 4 different brands til I found that the best one for me. My hair and nails grow SO much quicker. Also my energy levels are high. I continue to take biotin every day and now that I am no longer on my diet I eat whatever I want and I don't gain weight. So I highly recommend it to you. "

Emmadema May 29, 2017

For Dietary Supplementation: "Worst vitamin ever .I took it for less than a week ,and I am on my 3 month still having large cystic acne . So bad that I might have to either go for laser or chemical peel. I didn't even have a single pimple on my face and people used to compliment me for my skin. Worst worst worst supplement ever which affected my confidence. They really need to stop selling it ."

Bullfrog11 March 30, 2017

For Dietary Supplementation: "Worst supplement I EVER took. I developed cystic acne. Large pimples continued to develop even after I stopped taking the Biotin. I could not believe how huge the cysts formed under my skin. My chin literally was deformed with the cysts. I had one on my left side of the chin and one on my right. They were the diameter of a dime and massively swollen. I was so embarrassed, there was nothing to make them go away. I continue to get small cysts of acne randomly on my face, I never had acne like this before. DO NOT take this product. Terrible doesn't begin to describe it....and reducing the symptoms by drinking water with it does not help, nor taking a b vitamin, as people suggest."

For Dietary Supplementation: "I take this for my Chronic Fatigue Syndrome / Myalgic Encephalomyelitis .I heard that people with MS are in a study using 300-600 MG(!) not mcg, of Biotin. I tried taking 5MG which is the highest available in a pill. I got a nasty headache, but it seems like it was a one-off because I haven't had it repeated. I know it was the biotin though, because I didn't read enough. Apparently it can dehydrate you, so you have to drink a lot more water than you normally would. However, the very next day, I was "sick" in the flulike way that people with CFS/ME do. And the day after that I had tons more energy than before. I think it may have helped my immune system to wake up and fight the (much denied) virus that causes this disease. But I wouldn't have to guess if the CDC, NIH & FDA would fund ME/CFS research."

Hair, Skin & Nails (biotin) for Dietary Supplementation: "I have been taking SHEDAVI hair+ skin+ nails. I'm n my first bottle. I've been having more frequent headaches. I'm not the one the take any analgesic but I've been force to take one to relieve my pain. I also hallucinate a bit I see thing running around my house I know can't be there. I was wondering if anyone had experience the same side effects and should I stop taking it?"

Kristinmh94928 July 22, 2016

For Dietary Supplementation: "I've been taking Biotin off and on for a few years and have noticed that certain brands seem to cause more headaches ...and for someone who never really gets headaches the ones I got after taking it were just unbearable... stopped taking it and no more headaches so my suggestion is to stick with a well respected brand and if you can, just buy a small bottle first to see if you have a reaction... on the plus side I did see an improvement in my skin.. oh, and maybe it's just me but I also noticed if I took it at night I had the most bizarre dreams "

Notsogoodnonononono · Taken for less than 1 month January 24, 2016

For Dietary Supplementation: "I am a 30 year old married female. I took biotin for 5 days, 5000 mcg 2 pills a day and now my period is 3 days late (And counting.The pregnancy test is negative fyi). I found many posts online by users saying their menstruation cycle started later rather than sooner and they weren't pregnant. I just wanted to mention this possible side effect. Also this pill gave me pimples."

ProudARMYwife · Taken for 6 months to 1 year October 14, 2014

For Dietary Supplementation: "PEOPLE YOU HAVE TO DRINK TONS OF WATER WITH THIS VITAMIN OR ELSE. Biotin will give you acne. It will cause severe headaches. It will make you nauseous, and you will complain it doesn't work and give up. THIS IS WHY PEOPLE DON'T GET RESULTS. In reality your doing it wrong if your not getting enough water! It has worked wonders for me. I have lost hair due to medications and stress. I started noticing results in two weeks (eyelashes). Two months (scalp). And you will get hair growth everywhere. My hair has never looked more healthier."

Meganmariee December 30, 2013

For Dietary Supplementation: "Biotin is pure bliss. I have been taking it everyday at 5000 mg. It has definitely made improvement in my nails and hair. I have been taking it for a few months and my hair has grown almost two inches. Reading tons of negative reviews on other sites at first made me think that biotin would barely do anything, but that was wrong biotin definitely helped my hair, skin, and nails! Taking this everyday and sticking with it really makes a difference!"

Katie222 · Taken for less than 1 month June 28, 2013

For Dietary Supplementation: "I am 54 years old and have not had acne since I was a teenager. After only 2 days of taking 5000mg, my nose broke out in large red rosacea type pimples. I stopped the vitamin and did not get any more pimples."

For Not Listed / Other: "I have been taking biotin for about three years to improve my nails and hair. I can tell a great difference in the strengh of my nails. They no longer peel like onion skin but are very strong and healthy. There isn't much of a change in my hair."
