Vitamin D helps the body absorb calcium. Before buying calcium, assess your dietary intake: a supplement should fill a shortfall, not be added on top of an already adequate diet.
Compare the amount of elemental calcium and the serving size. Vitamin D requirements depend on individual circumstances; a high dose on a label does not mean it is suitable for you.
Appropriate weight-bearing activity is also important for bones. Persistent pain, joint swelling or suspected osteoporosis calls for a diagnosis, not a random collection of supplements.
Before use
Discuss supplementation with a doctor if you have kidney stones, high blood calcium or kidney disease. Calcium interacts with some medicines, including levothyroxine.
