how much magnesium per day for a man

The recommended daily amount of magnesium for an adult man is generally between 400 and 420 milligrams per day. This range is consistent for men aged 19 years and older, with the upper end typically recommended for men over 30 or 31 years. These amounts include magnesium from both food and supplements. It is also noted that getting magnesium from food sources is safe, but high doses from supplements should not exceed 350 to 400 mg per day without medical advice.
