R-ALA Sups

[Jcoz]

I have been doing alot of reading on R-ALA and have decided to get a supplement with Biotin.

These are the two I was looking at:

Glucorell-R (100mg RALA; 500mcg Biotin)

Insopro-R (100mg RALA 1mg Biotin)

Question is, can you overdo the Biotin? All things being equal in that dept., the Inspiro is cheaper.

Also, are there other R-ALA Sups better than these?

Thanks in advance. Possible important info is that I am under 200lbs.
