Foods High in Magnesium
By the USDA, National Agricultural Library, Food and Nutrition Center
Magnesium, when ingested as a naturally occurring substance in foods, has not been demonstrated to exert any adverse effects. However, adverse effects of excess magnesium intake have been observed with in-takes from nonfood sources such as various magnesium salts used for pharmacologic purposes.
