Each soft gel capsule supports your body's natural calcium metabolism, directing calcium to where it is needed most.*

• Bone health: MK-7 activates osteocalcin, a protein that binds calcium to the bone matrix, helping to keep bones strong and healthy.*
• Normal blood clotting: Vitamin K is essential for the production of clotting factors, ensuring proper coagulation.*
• Bioavailability: Unlike MK-4, MK-7 has a half-life of around 24 hours, providing sustained support with a single daily dose.

Understanding Vitamin K2: MK-7 vs. MK-4

Vitamin K2 (menaquinone) has several subtypes, with MK-4 and MK-7 being the most studied. MK-7, derived from fermented soybeans (natto), has a longer half-life than MK-4, meaning it remains active in the body longer and only needs to be taken once daily. This makes MK-7 the preferred form for maintaining consistent vitamin K levels throughout the day.

Who May Benefit from a Vitamin K2 Supplement?

While vitamin K2 is found in natto, cheese, and egg yolks, many people do not get enough from diet alone. Individuals who may consider supplementation include those concerned about bone density, postmenopausal women, older adults, and anyone seeking proactive support for their vascular system. Taking vitamin D alongside K2 is often recommended, as they work synergistically to regulate calcium metabolism.

Recommended Dosage and Usage

Each soft gel capsule contains 90 mcg of vitamin K2 as MK-7. The suggested uses is one soft gel capsule daily, preferably with a meal containing fat to optimise absorption. This 120-serving bottle lasts four months. Always consult your health care provider before starting a new supplement, especially if you are taking anticoagulant medication such as warfarin.

Safety Considerations

Vitamin K2 is generally well tolerated. However, because K2 supports blood clotting, individuals on warfarin or other anticoagulants should seek medical advice before uses. High doses may interfere with medication efficacy. Adhere to the recommended dosage and store the product in a cool, dry place away from direct sunlight.
