The methionine and some other "stuff" is important. I've read that
biotin alone won't do what biotin and methionine do together. I use
Biotin Plus and now only use 1/2 scoop (Serving) because I read on
RideCamp that the horse can utilize only so much of the stuff at one
time.

P.S. to Trish: as soon as I get my film back with a "pretty" picture of
my girl, I'm going to ask you for a picture of "pretty David"!
