Vitamin D3 from Natural Factors provides a convenient daily dose of vitamin D as cholecalciferol to help support immune function and for the development and maintenance of strong bones and teeth. Vitamin D3 is the natural form of this vital nutrient and is most effective at raising blood levels of active vitamin D.
Vitamin D plays a key role in the absorption of calcium and phosphorus, two minerals that are vital for proper bone mineralization and turnover. Vitamin D is also required for the body’s innate and adaptive immune responses.
Each tablet or softgel delivers a single 1000 IU (25 mcg) dose of vitamin D3 for convenient maintenance of adequate vitamin D levels, even when dietary intake and sun exposure are lacking. When combined with an adequate calcium intake, a healthy diet, and regular exercise, vitamin D3 helps reduce the risk of developing the brittle, weak bones of osteoporosis.
Vitamin D3 1000 IU is certified non-GMO and is available as tablets or softgels in 90, 180, 360, and 500 count bottles. This formula contains no artificial colours, preservatives, sweeteners, or common allergens, and is suitable for use during pregnancy and while nursing an infant.
