what is the recommended daily mg of magnesium for an adult?
A Stacy Wiegman, PharmD , Pharmacy, answered. The U.S. recommended daily allowance for magnesium depends on the individual. Adult men should get between 270 milligrams (mg) and 400 mg per day, while women only need around 300 mg, and children and adolescents need even less. Most people get enough magnesium from their diet.
