Maintaining strong, healthy bones is the cornerstone of successful aging. After middle age, changes in estrogen levels can cause bone loss to accelerate in both men and women. Even though the human skeleton contains large amounts of calcium, any prolonged deficiency of vitamin D or calcium in the diet may rapidly deplete these stores. Unfortunately, even health conscious adults often fail to consume enough calcium, vitamin D, and other specific nutrients that protect against age-related loss of bone density.
Human joints are also exceedingly vulnerable to the effects of aging. Everyday wear and tear and the accumulation of free radical damage from the overproduction of inflammatory cytokines and prostaglandins can lead to discomfort and loss of mobility.
