Vitamin D3 supports bone health, immune function, and calcium absorption with the most biologically active form of D3. Known as the "Sunshine Vitamin," it also aids muscle strength, emotional wellness, and blood pressure regulation.

While the body produces vitamin D when exposed to sunlight, many people—especially those with limited sun exposure or the elderly—may require supplementation. Aging reduces the body's ability to produce vitamin D, and studies suggest most people consume less than the recommended amount.

Ensure optimal levels with 1000 IU (50 mcg) of D3 as cholecalciferol in every serving.
