The recommended daily magnesium intake is a guideline determined by the Health Council that indicates how much magnesium we need on average per day in order to remain healthy. The magnesium intake differs from men to women:
Women: 250-300 mg/day (NB: 50 mg more for breastfeeding women)
Men: 300-350 mg/day
Actual individual requirements depend on personal factors and lifestyle. Excess magnesium is immediately expelled by the body.
Various studies such as the World Health Organization (WHO) have indicated that up to 80% of adults suffer from chronic magnesium deficiency.
