I bought this because it was a powder and a very high dosage with very little product. I find it works wonders, I have very regular bowel movements and it helps with my feeings of calmness. I have yet to feel stressed once and always feel wonderful taking my magnesium. I take it in the morning or night every other day to help me sleep, relieve muscle pain, improve bowel movements and relieve stress, I have seen wonderful results. Minimal taste, easy to get down, super small dose (1/4 tsp) with a high amount of Mg. NOW brand is a very good brand.
