Food supplement based on magnesium bisglycinate. Magnesium is a mineral with an infinite number of extremely important physiological functions in the body. However, in most industrialized countries, regular diets often do not contain high enough amounts of magnesium. Chelated magnesium from N&N contributes to reducing the deficiency of this mineral by having a high bioavailability and not causing gastrointestinal problems at the recommended doses. Instructions for use: Take 1 capsule a day.
