Vitamin A and Biotin

On my spread sheet vitalady says vitamin a should be between 60 and 80.  Mine is 43 so I think I need a little supplement.  I saw my surgeon Monday and he was unconcerned.  What amount should I start with is this low enough to worry with?  Also biotin.  I want to start taking biotin but don't know how much I should take.  Any suggestions? 

With the biotin I take 5000mcg= to 5 mg. but I have seen some on hear that take twice that. It does not stop your hair from falling out but does help with regrowth. And large amounts could cause unwanted face hair. I had that befor so no big deal to me. Hope that helps.

Hi I take 1000mg or they have 5,000 mg it really doesn't matter.I'll take 3,000 or 2,000 it's not going to hurt you at all.My hair is so healthy and strong.I also message my scalp with olive oil it works for me.
