What is Vitamin D3?
Vitamin D3 (cholecalciferol) is a fat-soluble vitamin that functions more like a hormone. Your skin produces it when exposed to UVB sunlight, which is why it's called the "sunshine vitamin."
Bone Health
Vitamin D's primary role is regulating calcium and phosphorus absorption, making it essential for building and maintaining strong bones. Without adequate vitamin D, bones can become thin, brittle, or misshapen.
Beyond Bones
Research has revealed vitamin D receptors in nearly every cell in your body, suggesting roles far beyond bone health. It modulates immune function, affects muscle strength, and may influence mood and mental health.
The Deficiency Epidemic
Vitamin D deficiency is remarkably common, especially in northern latitudes, among people with darker skin, the elderly, and those who spend limited time outdoors. Many experts consider it a widespread public health concern.
D2 vs D3
Vitamin D3 (from animal sources) is more effective at raising blood levels than D2 (from plants and fungi). For this reason, D3 is generally the preferred form for supplementation.
