I have only started using the product but I can say that I have noticed a difference in my skin, especially in my face. I also did some research and found that in the US prior to 1984 they found a history of biotin deficiency in people which affected a wide variety of things including memory loss. They would treat the condition at that time but stopped testing for it after 1984.
The powder is great but Groupon stinks! Had sooo many bad experiences now with Groupon and this was the final straw. I am NEVER buying anything on Groupon again. Their “deals” always turn out to be a bust and more trouble then they are worth.
