Magnesium is an important mineral our body needs each day because it is necessary for more than 300 metabolic reactions to take place. This includes our nervous system, muscles, bone health, energy production, immune system and heart health. We need to eat a variety of foods to meet our magnesium needs each day, which is around 400 mg for men and 300 mg for women. Good food sources of magnesium include leafy greens, low-fat dairy products, whole grains, nuts/seeds, legumes, tofu, wheat germ, oat bran and cacao or dark chocolate. Unfortunately around 45-50% of us do not eat enough of these foods each day, which can lead to decreased energy/chronic fatigue, muscle cramps and muscle pain, headaches, anxiety/depression, irregular heartbeat and osteoporosis. In some cases, supplementation may be helpful for those not eating enough foods rich in magnesium who are experiencing some of these symptoms. As always, please consult with your medical provider before taking any supplementation. And as a registered dietitian, I always recommend food first to get the most absorbable magnesium in your diet
