Helps Relax the muscles
I like to take a magnesium supplement daily, usually in the evening before going to be as it helps relax me for sleep

These work GREAT! This is the second time I've ordered them!
These work great! This is the 2nd time I've ordered these. They give me energy and my buddy down below get a lot of energy too! (especially in the morning!) :) I definitely recommend getting these I've tried different types on AMAZON and these are the best so far. Any other suggestions on these types of pills. Add this info in your review. May have to give it a week or so to see and feel the results and you will!
