Strong consensus that K2 is underrated and effective for cardiovascular and bone health, with some debate on optimal form and dosing.
Bioclinic Naturals Vitamin K2 100mcg delivers menaquinone-7 (MK-7), the long-chain form of K2 known for its extended half-life and sustained activity in the body, supporting calcium utilization and bone matrix protein activation. At 100mcg per serving, it's formulated for adults seeking to support cardiovascular and skeletal health as part of a broader wellness routine.
Why It's Worth Considering: MK-7 is the preferred K2 form for those prioritizing prolonged circulatory presence compared to shorter-chain MK-4, and Bioclinic Naturals applies a practitioner-grade standard to sourcing and potency verification.
Vitamin K1 (phylloquinone) is for blood clotting — abundant in leafy greens. Vitamin K2 (menaquinone) directs calcium metabolism — puts calcium in bones and keeps it out of arteries. Most people get enough K1 from diet but are deficient in K2, which is found mainly in fermented foods (natto, certain cheeses) and animal liver.
MK-7 is the most bioavailable and longest-acting form of K2, with a half-life of ~3 days (vs ~1 hour for MK-4). This means a single daily dose maintains therapeutic blood levels 24/7. MK-7 is derived from natto (fermented soybeans) and has the strongest clinical evidence for bone density and arterial health.
For general health with D3: 100-200mcg MK-7 daily. For osteoporosis: 180-360mcg. For cardiovascular calcification prevention: 180-200mcg. The dose should scale with your D3 intake — higher D3 doses require more K2 to handle the increased calcium absorption.
If you're on warfarin/Coumadin: NO — K2 counteracts warfarin and will destabilize your INR. Consult your cardiologist. If you're on newer anticoagulants (Eliquis/apixaban, Xarelto/rivaroxaban, Pradaxa/dabigatran): these are NOT vitamin K-dependent, so K2 is safe. Always confirm with your prescribing physician.
