What is Vitamin D3?
Vitamin D3, also known as cholecalciferol, is one of the most common forms of the vitamin D family. It is essential for maintaining bone health, supporting the immune system and cell growth. Vitamin D3 helps regulate the balance of calcium and phosphorus in the body, thereby promoting healthy bones and teeth. Additionally, Vitamin D3 has been linked to lowering the risk of certain chronic diseases, improving cardiovascular health, and supporting mental health.
