Vitamin MCG?

[mjeffers2]

Hello,

I'm a newbie. I used to be on here awhile ago, but now I'm back and on a mission to stick with my hair growth.

I have all the vitamins that most of you take, but I'm wondering, on average, how many mg's should I be taking of biotin, l-cystine, msm, and silica?

Thanks.

Monique
