What Is Calcium And What Does It Do?
Calcium is a mineral that is necessary for life. In addition to building bones and keeping them healthy, calcium enables our blood to clot, our muscles to contract, and our heart to beat. About 99% of the calcium in our bodies is in our bones and teeth.
Our bodies cannot produce its own calcium. That’s why it’s important to get enough calcium from the food we eat. When we don’t get the calcium our body needs, it is taken from our bones.
This is fine once in a while, but if it happens too often, bones get weak and easier to break.

The active vitamin D metabolite, 1,25-dihydroxyvitamin D (1,25(OH)(2)D) binds to the vitamin D receptor (VDR) in the intestinal cell and stimulates the active calcium transport from the intestine to the circulation.
A high calcium intake increases the half life of 25(OH)D. In patients with primary or secondary hyperparathyroidism, the half life of 25(OH)D is shorter. The effects of these trials also depend on baseline calcium intake, baseline vitamin D status, age and residence. These results confirm that an interaction exists between calcium and vitamin.
Abstract
Vitamin D has traditionally been known as the “bone vitamin”. Residual confounding or reverse causation may explain some of the discrepancy between the observational and trial results. Adding to this complexity is the fact that many adults take vitamin D and calcium supplements together for bone health, and there is some concern (albeit inconclusive) related to calcium use and increased CVD risk.
In this review, we discuss vitamin D and calcium supplementation and how they may affect cardiovascular health.
