Magnesium L-Threonate by Sports Research

After using the product for over a month I have notice much better sleep quality. I do feel it is helping with memory too. Is it a fix-all? No, but very helpful and I will continue to use this product. Purchased the first bottle from another place but found Walmart to have a better price for the second bottle.
