healthy bones. The amount of
calcium needed changes as a person grows older. Most Americans get only

recommended daily calcium intake for adults ages 19 to 50 is 1,000 mg a day,
increasing to 1,200 mg a day for adults older than 50. Calcium is found in
many foods, including dairy products such as milk or yogurt. Most
postmenopausal women need to take calcium supplements because they do not get
enough calcium in their daily diets.
MSM is a chemical in animals, humans, and many plants. People use it most often to try to treat arthritis.
MSM can be produced in a lab, where it is sometimes combined with other supplements such as glucosamine or chondroitin.
