D-1,000: Foundational Vitamin D3 for Daily Immune and Bone Health
Thorne’s D-1,000 delivers a balanced, daily-maintenance dose of Vitamin D3, an essential nutrient vital for whole-body wellness. Known as the “sunshine vitamin,” Vitamin D is crucial for a robust immune response, strong bones, and healthy muscle function. This formula provides 1,000 IU of pure, high-quality vitamin D3 per capsule, offering a simple and effective way to ensure optimal levels, especially when sun exposure is limited. As an NSF Certified for Sport® product, it’s a trusted choice for foundational health and daily support.
How It Works: The Science of the Sunshine Vitamin
Vitamin D functions more like a hormone than a vitamin, influencing thousands of genetic processes that are key to your health.
Support for Immune Readiness and Bone Density
This formula uses Vitamin D3 (cholecalciferol), the same form your body naturally produces from sunlight, which is significantly more potent and better utilized than the D2 form. Its most critical role is promoting the absorption of calcium, which is fundamental for maintaining bone density and strength. In the immune system, Vitamin D acts as a key modulator, supporting the healthy function of T-cells and other immune cells to ensure you’re ready to face seasonal challenges.
A Foundation for Overall Wellness
Beyond immunity and bones, maintaining adequate Vitamin D levels is essential for supporting healthy muscle function, promoting a positive mood, and contributing to cardiovascular health. The 1,000 IU dosage in Thorne’s D-1,000 is ideal for individuals looking to maintain healthy vitamin D levels year-round, providing a solid foundation for a healthy, active lifestyle.
