When our skin is exposed to sunlight, it produces a specific form of Vitamin D, which is called Vitamin D3. Vitamin D3 increases and maintains serum levels of Vitamin D better than Vitamin D2. But we don't always get enough sun exposure year-round, and even if we do, we still may benefit from a pure, high-quality Vitamin D3 supplement due to the benefits it can offer. Older adults, obese individuals, and people with limited sun exposure can be at increased risk of developing Vitamin D insufficiency. These groups may need dietary supplements to meet their Vitamin D requirements. USDA Organic Vegan Vitamin D3: 1,000 IU (25mcg) of Vitamin D3 in every serving. 100% vegan and alcohol-free formula.
