So, I actually bought this for my Grandma, which has Dementia. She has always been very sharp, and watching her decline in these years, really made me sad, at seeing her lose interest in her things she enjoyed. She had really started to lose part of her life, just laying in bed.. and staring at the walls- she used to read her Bible every day, do crossword puzzles, and of course watch, "Wheel of Fortune", and "Jeopardy".I did a ton of research, as I do for everything, and I know there is no "cure-all" for the disease, but there has to be something in where we can try to minimize, the symptoms. I have dealt many years in medicine, and figured I would try this supplement for her. I checked with her doctor, and we agreed that this will not hurt.. at least it has vitamins that we should have.. and if works.. awesome.. if not.. then that is okay too.The first couple days.. she started to get more "involved" in what she used to do.. and within a week, she was more walking around.. and spending less time asleep- she used to sleep about 15hrs/day. Now.. she actually wakes up during the day.. does a few things.. then takes a nap. She has been a lot more active, and she seems to be less agitated, and more productive. She seems to be doing better.. and we feel that this supplement has helped her some. I am not going to say that this is a "miracle", by any point. I can say, that since she has started taking this product, she has been more active, she can sleep better, she is less agitated when she can not remember what she is trying to recall, and she just seems to be more like she used to be.I can say, that studying medicine, I take a lot of products that make claims, and study them. I think that, at least for my Grandma, this product has helped her some.. not 100%! I would say about 50% more or less.. and am very grateful for the people who have posted on this product, and just wanted to put my opinion out there. I am hoping that this will continue to help her.. and if not.. then at least it has helped so far.I personally have started taking this.. and feel more alert, and am hoping to see the positive. Value.. it is a great value.. ingredients seem to be good quality. Thank you!
