As a very active and healthy man at the age of 69, I can do almost anything physically, but I was having some issues remembering from time to time. I generally do not take vitamins for allopathic reasons but I thought I would try this product to see if maybe I wasn't assimilating enough of the right nutrients to maintain healthy brain function. Though, I didn't notice much of a change in general, I did notice that I always had trouble remembering the 12 ingredients to my home made Caesar dressing. But there it was, to my amazement, I went to make the dressing and could instantly rattle off every ingredient. First time in 5 years! And to prove a point, I just did it again while writing this post. Therefore, I recommend this product to keep you sharp. As we age, some stuff has trouble getting digested and assimilated. Apparently, it was exactly what I needed. Who would have THUNK it? :-p
