Good if you want your muscles be relaxed.

Perhaps I haven't been using this long enough to notice effectivness but it didn't harm me and I do seem to have headaches which is the reason I am taking it for. Tastewise, it's not bad because it has no taste at all. The thing I don't like about this magnesium powder is that it just doesn't dissolve in water. I stir as quickly as I can, but as soon as I lift the glass, all of it is already on the bottom. Tried putting it in a smoothie, can still feel the sandy/chalky texture. I wonder if you can put it in food, like soups? Perhaps then it woudn't be such a pain to consume. <B>Goes Well With:</B> Smoothies I guess, better than water.

If you want to increase your magnesium intake then this Magnesium Citrate will do it. <B>Goes Well With:</B> zinc and magnesium pill

This Magnesium Citrate doesn't mix well with water. It stays at the bottom which makes it hard to drink.

I'm not too sure about the efficiency, although calf cramps haven't occurred since supplementation. On the other hand the laxative effect sometimes occurs very late rather than sooner so only time will tell.
