Too much choline...

5 people found the following review helpful

Posted by Reviewer2963961 From Oregon on Aug 07, 2010

Purchased at iHerb

This product gives me a stiff neck due too the choline in it. I have tried it many times and end up with a headache if used every day. I took for a couple of months & did not notice any improvement in hair, skin, or mails either.

I read an article about how bioavailable silica can increase bone matrix by 22%, but I don't think I will buy a second bottle because the taste is that bad!

I take this with Biotin supplements and Neocell Super Collagen and after 3 months have noticed a dramatic improvement to my hair loss problem.. Highly recommended.
