I just got an e-mail from my dietician, where I asked her about Biotin (what it does, how much to take) and she gave me the lowdown:

Biotin does not prevent hair loss. Period.

Large amounts of Biotin is unnecessary, and will cause the kidneys to work harder, and you "just pee it out, anyway".

Suggested normal dose was 30mcg a day. Apparently the smaller dose can be hard to find.

Biotin can potentially regrow hair!!!

Sorry if this bursts anyone's bubble, just thought you might want to know.

Its all good. It has made my skin and nails nice. Still waiting to re grow hair.

@ I take a large does, my hair is growing, I've yet to lose any hair and my labs are PERFECT! So I guess it depends on your body.

@@Rocky1 Again, I have to quote her for the dosage at 30mcg, a very small amount, indeed!

I take two 5,000mg pills a day, My hair seems fine. My nut has no issue with me taking it and it's not a very expensive pill so I think I'll stick with it.

I grew more hair everywhere. I had to stop taking it - just as I began to lose my hair from the surgery! But it was that or look like a Yeti and I'm already furry from PCOS.
