Been taking the Bamboo supplement now for 6 months, along with 1 Lessman per day and extra Biotin , both which I have been using for years, no difference. I see that Puritans Pride has a very good H, S, N supp with Verisol collagen in it, once my supply of Bamboo is gone, I am going to try that, cant hurt.
I do agree, Joyce's ingredient deck is top notch.
