Vitamin D3 2,000 IU

The Sunshine Vitamin. Your Performance Depends on It.

D1 Body's Vitamin D3 2,000 IU is the essential hormone-like vitamin that most athletes are chronically deficient in — and the one that impacts nearly every aspect of your performance and health. Vitamin D3 plays a critical role in testosterone production, muscle function, immune defense, bone density, and mood regulation. Without adequate levels, your body simply cannot perform at its genetic potential.

D1 Body Vitamin D3 is formulated in the most bioactive D3 (cholecalciferol) form — the same form your body produces from sunlight — for maximum effectiveness. Whether you train indoors, live in a low-sunlight region, or simply want to optimize your levels, this is the supplement that fills the gap.

• ✅ 2,000 IU of bioactive D3 (cholecalciferol) per serving
• ✅ Supports healthy testosterone levels and muscle function
• ✅ Strengthens bones and reduces injury risk
• ✅ Boosts immune function and reduces inflammation
• ✅ Improves mood, motivation, and mental well-being

D1 Body Vitamin D3 is the foundational supplement that unlocks your body's full performance potential. Don't let a deficiency hold you back — optimize your D3 and train at your true ceiling.
