Vitamin K2+D3

Vitamin D3 tells your body to absorb calcium. Vitamin K2 tells that calcium where to go — into bones and teeth, and away from arteries and soft tissue. Take them apart and you get half the story. Take them together — and you complete the loop. MD Vitamin K2-D3 pairs 5,000 IU of lichen-derived D3 (the only fully vegan source of cholecalciferol) with 90mcg of K2 as menaquinone-7 from natto fermentation. MK-7 has a half-life of approximately 72 hours — compared to just 1–3 hours for MK-4 — meaning one capsule delivers all-day vitamin K activity. Both vitamins are fat-soluble, so a single capsule taken with breakfast covers your daily needs.
