Doctor's Best Vitamin D3 (5000 IU, 125 mcg) provides high-potency cholecalciferol, the form of vitamin D most readily used by the body. Vitamin D plays a crucial role in calcium and phosphorus absorption, essential for maintaining strong bones, teeth, and a healthy heart. While the body produces vitamin D through sun exposure, factors such as sun protection and climate can lead to deficiencies. This supplement helps bridge that gap.
