1000 mg
1500 mg
2000 mg
500 mg

Explanation:

1. Calcium is a major component of bones, and phosphorus works with calcium to build and maintain bone structure. Vitamin D is a vitamin (not a mineral). Magnesium and potassium have other roles in the body not as central to bone density as calcium and phosphorus.
2. Regular physical activity stresses bones (in a good way) which signals them to stay strong. Excessive alcohol can interfere with calcium absorption and bone metabolism. High caffeine intake can increase calcium excretion. So all these measures promote better bone health.
3. The Recommended Dietary Allowance (RDA) for calcium for non - pregnant, non - lactating women aged 19 - 50 is 1000 mg per day.

Answer:

1. Calcium and phosphorus
