Vitamin D3 10,000 IU – Immune, Bone & Muscle Support

Vitamin D3 10,000 IU  — Immune, Bone & Muscle Support

Most people are deficient in Vitamin D — and most don't know it. This fat-soluble vitamin plays a critical role in immune defense, calcium absorption for bone density, and muscle function, yet modern indoor lifestyles and sunscreen use make it nearly impossible to get enough from sunlight alone.

Vitamin D3 (cholecalciferol) is the most bioavailable form, matching what your skin naturally produces from sun exposure. At 2,000 IU daily, it's a safe, effective foundational dose for year-round support.

What It Supports

• Immune system resilience and defense
• Calcium absorption and bone density
• Muscle function and strength
• Mood balance and seasonal wellness
• Cardiovascular and metabolic health

How to Use

Take as directed daily with a fat-containing meal for optimal absorption. Pairs well with Vitamin K2 to direct calcium to bones rather than soft tissue. Consult a healthcare professional before use if you are pregnant, nursing, taking medications, or managing a health condition.

Why This Formula

Iron Faith Nutrition's Vitamin D3 uses the D3 (cholecalciferol) form — the most bioavailable and effective form — in a clean, stackable daily capsule with no unnecessary fillers.
