Jamieson vitamin D 1,000 IU , 150 + 30 Softgels

For years, Vitamin D has been associated with bone health — a deficiency has been aligned with rickets in children and osteomalacia and osteoporosis in adults. Vitamin D plays an important role in how our bodies use calcium, specifically it effectively steers calcium to building, maintaining and reinforcing our bones and teeth.

New data from major health organizations, including the Canadian Cancer Society, point to a daily supplement of 1,000 IU (plus any amounts from sunlight and food) for optimal cancer prevention. Especially important during fall and winter months when sunlight is limited, this dose is a good year-round maintenance level for seniors, people with dark complexions and anyone who spends a significant amount of time indoors.

The body uses Vitamin D in complex ways. At the outset, the liver and kidneys turn Vitamin D3, or cholecalciferol, into Vitamin D molecules that circulate in the blood to regulate bone-building calcium. Once your circulating Vitamin D levels exceed the critical minimum needed to monitor calcium, the sunshine vitamin heads straight to work on your cells. Scientists believe it is this path of action that explains Vitamin D’s disease-fighting power. Cancer prevention is Vitamin D’s most impressive feat, but the sunshine supplement also supports heart health, fights major diseases of the blood and muscles, and reduces the risk of diabetes.

According to the latest research, more than two-thirds of all adult Canadians receive less than adequate amounts of Vitamin D for optimal health. Made with premium Vitamin D3, Jamieson easy-to-swallow Vitamin D 1,000 IU Softgels contain the same form of Vitamin D that the body naturally produces when skin is exposed to sunlight.
