From reviewing studies, one of them had the men taking 10 mg/kg of body weight per day; for me that equals about 900 mg of magnesium daily.
Since I don't know how much magnesium is in the spinach and broccoli I'm eating, I'm going to put the magnesium tablets to just one every workout day since I may have a build up of it in my body.
Just to be safe. 🙂
