Vitamin D3
Brand: Natures Plus Source of Life Garden
Dr. Feb's Analysis
Scientific Mechanism
This supplement delivers Vitamin D3 (cholecalciferol) in a 5000 IU dose, which is converted in the liver and kidneys to calcitriol, the active hormonal form. At the cellular level, calcitriol binds to Vitamin D Receptors (VDR) in immune cells and osteoblasts. This binding modulates gene expression, promoting calcium absorption in the gut and regulating immune response pathways. The Certified Organic Mushroom Blend (500 mg) provides beta-glucans and polysaccharides that may further support innate immunity by activating macrophages and natural killer cells, working synergistically with Vitamin D3.
Key Benefits
Key benefits include:
- Enhanced calcium absorption for strong bones and teeth

- Support for healthy mood and seasonal wellness
- Plant-based, vegan-friendly nutrient delivery
