The review
Why we put this on the shelf.
K2 directs calcium to bone instead of arteries. The MK-4 form Thorne uses is the body's preferred isomer — clinically dosed at the level used in Japanese osteoporosis research.
We carry Vitamin K2 because Thorne sets a bar most consumer-facing supplement brands don't clear: NSF-certified manufacturing, in-house clinical research with Mayo Clinic and the Mayo Clinic Sports Medicine team, and individual batch testing for purity and potency.
