Calcium supports more than just healthy bones. It’s also important for muscle contraction, blood vessel contraction, and expansion, secretion of hormones and enzymes, and sending messages through the nervous system.1 A meta-analysis of 40 clinical trials demonstrated a significant impact on already-healthy blood pressure as a result of increased calcium intake by an average 1,200 mg/day.2 In addition, scientific research suggests that increased intake of calcium may help maintain a healthy weight.3,4

Calcium is an essential mineral that is often inadequately supplied, inefficiently absorbed, or excreted faster than it is assimilated.5 The citrate salt of calcium has been shown to be well absorbed and utilized by the body.6 This is the form many doctors and nutritionists recommend.

Calcium citrate dissolves easily, even if one doesn’t have ample stomach acid. As many people naturally produce less acid as they age, calcium citrate is a good choice for older adults.1,7 The addition of vitamin D3 encourages calcium absorption and promotes healthy bone density. However, as people age, they often lose the ability to make vitamin D3.8
