How does vitamin D3 work? Vitamin D3 is essential in the development of strong bones by increasing the body's absorption of calcium. It is synthesized in the body from sunlight; only a small amount can be obtained from food. The winter season and almost all sunblock products inhibit the body's ability to produce optimal levels of vitamin D3 making vitamin D3 supplementation even more necessary to ensure your body receives an adequate supply.
