Taurine is in one of my Alpha Lipoic supplements. Biotin also.

Long term ALA can reduce Biotin levels so that is nice. Biotin and Taurine are both important for insulin function.

I get Biotin in my Multi, Ultra Preventive X by Pure Prescriptions also.

My ALAMAX by Xymogen has Biotin also. I usually take that one, sometimes I take the ALA Supreme.
