Vitamin D

Vitamin D, also known as the “sunshine vitamin”, is made naturally in the skin from exposure to the sun’s ultraviolet rays. It helps with the absorption of calcium and phosphorus for normal bone mineralization, is essential for proper immune system activity, and supports cell growth and nerve and muscle function. When sun exposure is low, dietary sources of vitamin D become critical. Natural Factors offers a range of vitamin D supplements for all ages in the preferred cholecalciferol (D3) form.
