Role of Calcium
Calcium is important because its presence or absence in the body can affect the nervous system, the overall metabolism, muscle contraction, and hormone production, as well as nutrient uptake and bone density. Without enough calcium in our , the body will begin leeching it from the bones, which speeds up the process of aging and increases the risk of osteoporosis. Calcium also plays a key role in blood and in the transfer of messages throughout the body.
When the body detects a lack of calcium, it can take additional calcium from the bones, while also using vitamin D to stimulate increased uptake of dietary calcium from our meals. We don’t naturally produce calcium, so we need to get it from our diet, or through supplementation. Thus, a deficiency in vitamin D, which our bodies produce when we are exposed to sunlight, can also lead to a deficiency of calcium.
