What is calcium?

Calcium is a mineral found in many foods. The body needs calcium to maintain strong bones and to carry out many important functions. Almost all calcium is stored in bones and teeth, where it supports their structure and hardness.

Bone Health

Bones need plenty of calcium and vitamin D throughout childhood and adolescence to reach their peak strength and calcium content by about age 30. After that, bones slowly lose calcium, but people can help reduce these losses by getting recommended amounts of calcium throughout adulthood and by having a healthy, active lifestyle that includes weight-bearing physical activity (such as walking and running).

"Calcium is an essential mineral for the human body. It is especially important for children, postmenopausal women, and the elderly, as it is needed to build and later maintain strong bones. Elm & Rye provides a calcium supplement that is third-party tested to ensure you’re getting the exact dose listed on the bottle."
