More category questions
What is the difference between K1 and K2?
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.
What is MK-7 and why is it the preferred form?
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.
How much vitamin K2 should I take?
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.
Can I take K2 if I'm on blood thinners?
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.
