Vitamin K2 (MK-7) Tablets - 60
Aiwo K2-MK7 contains Vitamin K2 (as Menaquinone 55mcg ).
It is a fat-soluble vitamin responsible for blood coagulation and plays a critical role in improving bone density and the strength of teeth. It reduces the risk of bone fractures and improves cardiovascular health by activating a protein which binds excess calcium to prevent calcification of arteries and soft tissue.
It works by providing vitamin K that is needed for blood to clot normally in the body. Vitamin K plays a key role in blood clotting and helps produce 4 of the 13 proteins needed for blood clotting.

What is Protocol?
A protocol is a daily system of supplements each one targeting specific longevity pillars.
Not All Vitamin K2 Supplements Deliver the Same Results
Bone Activation
Arterial Protection
- Key Proteins Activated (Osteocalcin + MGP) With a 72-hour half-life, a single daily tablet maintains consistent K2 activity throughout the day and night — MK-4 requires multiple doses to achieve comparable coverage.
- K-7 activates two critical proteins: Osteocalcin (directs calcium into bone matrix) and Matrix Gla Protein or MGP (keeps calcium out of arterial walls). Both require carboxylation by Vitamin K2 to function. Without adequate K2, calcium circulates — potentially depositing in arteries rather than bones.

Straight answers.
Vitamin K1 (phylloquinone) is found in leafy greens and plays a primary role in blood clotting — its activity is largely confined to the liver. Vitamin K2 (menaquinone) travels beyond the liver to bones and arteries, where it activates two critical proteins: Osteocalcin (for calcium binding in bone) and Matrix Gla Protein or MGP (to prevent calcium from depositing in arteries). Most people get adequate K1 from diet — K2 is where the gap exists for bone and arterial health.
Both are forms of Vitamin K2. MK-7 has a half-life of approximately 72 hours — meaning a single daily dose maintains active K2 levels throughout the day and into the next. MK-4 has a half-life of just 1–2 hours and requires multiple higher doses per day to achieve comparable effect. For a daily supplement protocol, MK-7 is the preferred clinical choice.
Adults over 35 looking to support long-term bone density and arterial health, individuals supplementing with Vitamin D3 (D3 increases calcium absorption — K2 ensures that calcium is correctly directed), those with family history of osteoporosis or arterial calcification, and anyone looking to complete their calcium metabolism protocol. Your Certified Dietician will determine whether K2 MK-7 belongs in your protocol.
Yes — Vitamin D3 and K2 MK-7 are synergistic. D3 significantly increases calcium absorption from the gut. K2 then activates the proteins that direct that calcium to bones (Osteocalcin) rather than arteries (MGP). Taking D3 without K2 increases circulating calcium — K2 ensures it ends up where it belongs. AIWO Vitamin K2 MK-7 pairs naturally with any D3 supplementation protocol.
Vitamin K plays a role in coagulation. If you are on anticoagulant medication such as warfarin or other Vitamin K antagonists, consult your doctor before supplementing with any Vitamin K form. Do not self-supplement. Your Certified Dietician will advise appropriately for your protocol.
