Why Vitamin D3?
Vitamin D exists in two forms: D2 and D3. Of the two, D3 is the more bioactive form, meaning it’s easier for your body to use. It plays a key role in maintaining normal calcium and phosphorus levels, supporting bone mineralization, and promoting neuromuscular health. Research also shows Vitamin D supports immune defenses by helping regulate lymphocytes, cytokines, and macrophages, key players in your body’s protective response.

Did You Know?
Vitamin D was first identified during research to cure rickets in the early 1900s. Scientists such as Sir Edward Mellanby, Elmer McCollum, and Adolf Windaus helped uncover how sunlight enables the body to produce this essential nutrient, revealing why it remains one of the most important vitamins for whole-body health today.
