Vitamin D3, also known as cholecalciferol, is more than just a vitamin—it’s a vital nutrient that your body naturally synthesizes from sunlight. Once absorbed, it converts to its active form, calcitriol, which plays a critical role in maintaining calcium and phosphorus balance, supporting strong bones, immune health, and overall well-being.
Vitamin D3 binds to receptors throughout the body, influencing key processes like gene expression and calcium regulation. It enhances calcium absorption in the gut, helping to maintain strong bones and teeth. Additionally, it plays a key role in immune function, supporting the body’s ability to fight infections and reduce inflammation.
