Dr. Feb's Analysis

Scientific Mechanism

Vitamin D3 (cholecalciferol) is the bioactive form of vitamin D. Upon ingestion, Vitamin D3 is metabolized in the liver and kidneys to calcitriol. This active hormone binds to Vitamin D Receptors (VDR) found in almost every cell, including immune cells and enterocytes. This binding triggers gene expression that regulates calcium transport proteins, facilitating calcium absorption in the gut. Simultaneously, it modulates cell growth and reduces inflammatory cytokines, directly supporting cardiovascular and immune system integrity.

Key Benefits

Key benefits include:

Supports immune system function and response
Promotes cardiovascular and heart health
Enhances calcium absorption for bone strength
Aids in normal cell development and differentiation

Usage & Safety

The standard dosage is 1 tablet daily, providing 1,000 IU (25 mcg) of Vitamin D3. For optimal absorption, take with a meal containing healthy fats, as Vitamin D is fat-soluble. Consult a healthcare provider before use if you are taking medications for hyperparathyroidism or have kidney disease. Avoid simultaneous intake with cholestyramine or mineral oils.
