Calcium is an essential nutrient that helps build and maintain healthy teeth and bones. Calcium also plays a role in muscle contraction, blood clotting and nerve function.* Most notably, as part of a healthy diet, adequate calcium throughout life may reduce the risk of osteoporosis, a disease that's characterized by a decrease in bone mass and an increase in bone fractures.
Calcium is important to people of all genders and ages. Men would benefit by taking calcium supplements; one in eight men over 50 years of age will sustain an osteoporosis-related fracture in his lifetime. Calcium is also important for children. Even postmenopausal women can benefit from calcium intake as this can help slow the rate of bone loss. Adequate calcium throughout life, including during peak bone-mass-building years, as part of a healthful diet, may reduce the risk of osteoporosis later in life.
