Health Benefits
Bone Health
Activates osteocalcin, a protein essential for binding calcium to bone tissue, improving bone density and reducing fracture risk.
Cardiovascular Support
Prevents arterial calcification by activating matrix Gla-protein (MGP), supporting vascular health.
Cognitive Health
Protects neurons and supports brain function, reducing the risk of age-related cognitive decline.
Cellular Repair
Enhances cellular health by reducing oxidative stress and supporting mitochondrial function.
Hormonal Balance
Regulates calcium metabolism in reproductive tissues, supporting overall hormonal health.
Origin & History
Menaquinone-4 (MK-4) is a highly bioactive subtype of vitamin K2, critical for calcium metabolism, bone health, and cardiovascular protection. Naturally occurring in animal-based foods such as organ meats and eggs, MK-4 activates specific proteins essential for directing calcium to bone tissue and preventing its deposition in arteries. It is widely used in supplements to enhance bone density, prevent arterial calcification, and promote systemic well-being.
“While Vitamin K was discovered in the early 20th century, the specific roles and benefits of Menaquinone-4 (MK-4) have been elucidated through modern scientific research. Its targeted action in calcium metabolism represents a contemporary understanding of nutrient-gene interactions, without a specific traditional medicinal history.”Traditional Medicine
Scientific Research
Menaquinone-4 has been studied extensively for its role in bone and vascular health. Modern research highlights MK-4 as a key nutrient for preventing bone loss, arterial calcification, and promoting systemic wellness.

Frequently Asked Questions
What is Menaquinone-4 (MK-4)?
MK-4 is one of several subtypes of vitamin K2, a fat-soluble vitamin essential for calcium metabolism. It activates osteocalcin (which deposits calcium in bones) and matrix Gla-protein (which prevents calcium buildup in arteries). MK-4 is found naturally in animal foods like egg yolks, organ meats, and butter.
What is the difference between MK-4 and MK-7?
Both are forms of vitamin K2 but differ in half-life and dosing. MK-4 has a short half-life of about 6–8 hours and requires higher or more frequent doses. MK-7, derived from fermented foods like natto, has a half-life of about 72 hours and maintains stable blood levels with once-daily dosing. Japan uses pharmacological MK-4 doses (45 mg/day) for osteoporosis treatment.
Can I take MK-4 if I am on blood thinners?
No — MK-4 and all forms of vitamin K2 are contraindicated with warfarin and other vitamin K antagonist anticoagulants, as they directly counteract the drug's mechanism. If you are on any anticoagulant therapy, consult your physician before taking vitamin K2 supplements. INR monitoring is essential if co-administration is considered.
