Our Vitamin D3 5000 contains 5,000 IU of vitamin D3 as cholecalciferol, along with vitamin K, which assists in some of vitamin D’s crucial functions. Evidence indicates that vitamin D3 is more effective than the D2 form, which is most commonly used in fortified foods.

Vitamin D plays a role in supporting the immune system and is a key player in bone health and calcium regulation in the body. When the body needs calcium, vitamin D stimulates the intestines to absorb more calcium from foods and reduces the amount of calcium the kidneys release into urine to be excreted. When blood levels of calcium are low, vitamin D triggers a natural hormonal process that allows calcium to be released from bones to restore proper blood levels.
