Vitamin D3 helps your body absorb calcium from food, while Vitamin K2 (as menaquinone-7) directs that calcium to your bones and away from your arteries. This dynamic duo supports normal bone density and may help maintain arterial flexibility. Each tablet provides 400 IU of cholecalciferol (D3) and 100 mcg of MK-7 K2, a form that lasts up to 12 times longer in the body than other K2 forms.*\u003c\/p\u003e\u003ch2\u003eUnderstanding the Synergy: How D3 and K2 Work Together\u003c\/h2\u003e\u003cp\u003eThe partnership between Vitamins D3 and K2 is all about calcium management. Once D3 boosts calcium absorption in the gut, K2 activates osteocalcin and matrix GLA protein (MGP). Osteocalcin binds calcium to bone tissue, while MGP helps prevent calcium from building up in blood vessel walls. This one-two punch helps maintain calcium balance, supporting both skeletal strength and cardiovascular health. The MK-7 form offers a sustained release, keeping those proteins activated throughout the day.\u003c\/p\u003e\u003ch2\u003eWhy Combine Vitamin D3 and K2?\u003c\/h2\u003e\u003cp\u003eTaking Vitamin D3 alone can increase calcium absorption, but without enough K2, that calcium may end up in soft tissues like arteries. By pairing D3 with K2, you ensure calcium goes where it's needed—your bones—and not where it's not. This synergy is particularly beneficial as we age and bone density naturally declines. Source Naturals Vitamin K2 + D3 provides a balanced 400 IU D3 and 100 mcg K2 (MK-7) to support this critical process.*\u003c\/p\u003e\u003ch2\u003eQuality You Can Trust\u003c\/h2\u003e\u003cp\u003eSource Naturals has been a trusted supplement manufacturer for over 40 years, founded in 1982 by CEO Ira Goldberg.
