Sports Research Vitamin D3 + K2

A clean pairing: vegan D3 from lichen plus MK-7, the K2 form with the strongest carboxylation data. The honest caveat is dose-context — 5000 IU is generous, and most useful when a blood test shows you're deficient, since trials in already-replete adults (VITAL) showed limited added benefit. Test first. Don't guess.

5000 IU D3 · 100mcg K2 (MK-7) · VEGAN
