What is vitamin D3?
Vitamin D3 (cholecalciferol) is the same form of vitamin D your body naturally produces when your skin is exposed to sunlight. Vitamin D3 is considered the preferred form for maintaining healthy vitamin D levels.*
Why is vitamin D3 considered the preferred form?
Vitamin D3 is the preferred form of vitamin D because research shows it is more effective at raising and maintaining healthy vitamin D levels in the blood than vitamin D2.*
Should vitamin D3 be taken with vitamin K2?
Vitamin D3 and vitamin K2 work synergistically in the body. For individuals supplementing with vitamin D, adding vitamin K2 can provide complementary support for bone and cardiovascular health.*
