Magnesium is a key mineral in the structure of the bone matrix and is also required for more than 300 biochemical reactions in the body. If blood magnesium levels drop, magnesium will be pulled from the bones. Magnesium deficiency is common and supplementation can assist in maintaining bone density and preventing back problems. This nutrient also helps in relaxing and contracting muscles, making it necessary for strengthening the muscles that support the spine.
Magnesium is found in green leafy vegetables, fish, beans, seeds, nuts, whole grains, yogurt, avocados, bananas, and dark chocolate (70% cocoa or higher).
