"The synergistic duo — vitamin D3 + K2 in coconut oil for optimal calcium metabolism"
Overview
Sports Research Vitamin K2 + D3 provides 5000 IU of vitamin D3 and 100mcg of vitamin K2 (as MK-7) per veggie softgel in a coconut oil carrier. The D3 + K2 combination is increasingly recognized as the optimal way to supplement vitamin D — K2 directs calcium to bones and teeth rather than arteries, addressing a key concern with high-dose D3 supplementation.

Our Verdict
Sports Research K2 + D3 is the smart way to supplement vitamin D. The K2 (MK-7) ensures calcium goes to your bones, not your arteries — addressing the main safety concern with high-dose D3. The coconut oil carrier aids fat-soluble vitamin absorption. If you're taking 5000 IU D3, adding K2 is a no-brainer.
