TweetYeah that is concentrated in multiple GRAMS not 400 mg. If you wish mag oxide is also good. it is the salt attached to the mag molecule. citrate is a natural salt and oxide is inorganic. Oxide is what you find the most. It is what I have right now.
$00 mg before bed is fine for most folk and helps me a lot. if it is bad then 400moring and 400 eve (with food or milk)
