In addition to supporting bone health, vitamin D plays an important role maintaining cardiovascular health and immune function, and promoting an overall sense of well-being. This product is ideal for those who want a once-a-week dosing regimen for their vitamin D supplement.

Vitamin D is a steroid vitamin, a group of fat-soluble pro-hormones that are best known for the role they play in supporting bone health and aiding in the absorption of calcium and phosphate from the gastrointestinal tract. However, a growing body of research highlights its important role in supporting other body systems, including cardiovascular and blood sugar balance as well as increasing musculoskeletal strength, neurological and immune function enabled by its ability to target over 200 different genes throughout the body. At the same time, deficiency and insufficiency of this important nutrient has reached epidemic proportions around the world, making the achievement of optimal levels extremely important to overall health. Known as the sunshine vitamin, one of the key roles of vitamin D is maintaining serum calcium and phosphorous balance. The body makes vitamin D by converting vitamin D2 to D3, or cholecalciferol, when exposed to sunlight. Vitamin D3 is also the form which the body derives from dietary cholesterol. While vitamin D is available in both forms as supplements, studies have found vitamin D3 is the preferable form, as it has been found to maintain active vitamin D levels for a longer period of time. Vitamin D3 50,000 IU is ideal for those who have difficulty achieving and maintaining peak vitamin D levels. This often includes elderly patients with low vitamin D levels; those with challenges in absorbing and maintaining vitamin D levels; and overweight patients with an elevated body mass index that impairs vitamin D circulation requiring significant repletion doses. For those who require an immediate boost in their vitamin D status, Vitamin D3 50,000 IU is a convenient, effective way to get the substantial support they need.
