Anyone taking Biotin?

I bought some Biotin this weekend in Grand Forks and it is 5000IU capsuls.  Does anyone else take it and how much per day?

i take it daily.i have for months now.i take 1000 mcg a day.it seems to help with the hair but it also helps with the leg and armpits too.i shave them alot more than i used too

Well that will be a change for me as I have almost no leg hair and little arm hair. 

i was like that too.i used to shave once and a whiole and now its almost every other day.but i will put up with it if it helps the head hair

I started taking Biotin 6 mths before my surgery, 1000 a day.I also took Silica 6 mths before surgery but not after.
At 9 mths after the surgery I take 2x1000 a week, I am 13 mths out and my hair has never been healthier.
I am one of the very few that had no hair loss

How do you know if you should take this?  Should everyone take this?  When should we start?  Where do you buy it?  (Sorry for all the questions....

 I`m having my RNY on August 1st....

From the little reading I have done on this it is a suppliment to improve skin, nails and hair. Since hairloss often goes with WLS somewhere around 6-9 mons post op some people start taking it to promote regrowth. Some people says it has worked well others haven't noticed a difference. I am going to give it a try but am skeptical in my situation as I have had thin hair and hairloss that started 20 years ago. But heck can't hurt to try.
