While calcium is crucial for bone health, magnesium is equally vital, especially for women over 40. Magnesium aids in bone structure, strength, and the proper allocation of calcium to bones. It also supports Vitamin D production, enhancing calcium absorption. Magnesium levels can be depleted by stress, poor sleep, digestive issues, and diets low in whole grains and legumes. Boosting intake through almonds, spinach, beans, and dark chocolate can support bone density.
