Strong consensus that Vitamin K2 is underrated and highly beneficial for bone, cardiovascular, and metabolic health, with minimal reported side effects.
DaVinci Labs Vitamin K2+ Resveratrol combines menaquinone-7 (MK-7), the long-acting form of vitamin K2, with trans-resveratrol to support cardiovascular health, healthy bone metabolism, and vascular integrity. This formulation is designed for adults seeking complementary support for calcium utilization and circulatory wellness.
Why It's Worth Considering: MK-7 offers extended biological activity compared to MK-4, and pairing it with trans-resveratrol — the bioactive polyphenol form — reflects a practitioner-informed approach to synergistic cardiovascular and skeletal support.
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.
