See your doctor: Hair loss may occur for many different reasons, the most significant of which is hypothyroidism. So you need an general evaluation. Biotin deficiency is extremely rare - it is found in many common foods and actually produced by bowel bacteria. There is no evidence that increased levels of biotin provide any health benefit. ...Read more

I would like to know the side effects of the vitamin Biotin. I read it is good for you but could be harmful. What is your opinion?

Very safe but...: Biotin is considered very safe and non-toxic in even very high doses. However, there are reports of high doses (over 2500 mcg/day) causing acne in some, but I am unaware of studies proving this. There is also concern high doses might interact with some seizure meds. See http://lpi.oregonstate.edu/infocenter/vitamins/biotin/ for a good discussion. ...Read more

What is biotin used for and what are the side effects?

Another supplement..: Biotin deficiency is rare, but can occur in persons with genetic mutations, on long-term antibiotics or anti-convulsants, or who eat a lot of raw egg whites.

Will biotin help for skin glowing? any side effects?

Glowing: I am unsure if you want your skin to glow, or are already glowing and want to stop. Either way, biotin is unlikely to make it happen. It certainly has not been rigorously tested to see its effectiveness. That being said, it is safe in normal doses. Side effects can include acne, allergies and an increased risk of miscarriage. ...Read more

Can I take 10,000 mcg of biotin? Is it safe? Are there any side effects?

Can I take 10,000 mcg of biotin? Is it safe?  Are there any  side effects?

Seems very unnatural: Not a natural thing to do. Biotin deficiency is rare, but can occur in persons with genetic mutations, on long-term antibiotics or anti-convulsants, or who eat a lot of raw egg whites. There is no good evidence that this easily available, over-the-counter supplement is the magic potion for anything. Biotin is safe to take, but 10000 mcg per day is over 60 times the usual dose, so is not advisable. ...Read more
