Formulation Notes

Supports Bone Health D3 + K2 + vitamin A are vitamins that build healthier, stronger, more resilient bones. Vitamin D oversees the absorption and use of calcium by the body & bones.

Promotes Heart Health and Immune Function Vitamin D3 supports cardiovascular functions. Vitamin K2 (MK-7) is a special form of vitamin K which directs calcium to your bones instead of your arteries, where too much calcium could be problematic. Vitamin A (and D3) both enhance immune system functions for overall well-being.
