vK2 Vitamin K2 Supplement – MK-4 + MK-7 – Dual Form – 60 Capsules

The Science Behind Dual-Form K2

Most vitamin K2 supplements offer only one form of menaquinone, but research suggests both MK-4 and MK-7 play distinct roles in the body. vK2 provides 5 mg of MK-4 and 100 mcg of MK-7 per capsule, combining fast-acting and long-lasting support for calcium regulation. This dual-action approach is designed to optimise your body's uses of calcium, supporting normal bone health and blood clotting.*

How vK2 Supports Your Health

Vitamin K activates proteins that direct calcium to where it is needed—bones and teeth—while helping to prevent calcium build-up in arteries. This contributes to the maintenance of normal bones and normal blood clotting.*

• Bone Maintenance: K2 activates osteocalcin, which binds calcium to the bone matrix. Adequate intake may help maintain bone mineral density, especially during ageing.*
• Circulatory Health: K2 activates matrix Gla-protein, which inhibits calcium deposition in arterial walls. Population studies link higher K2 intake with healthier arteries.*
• Vitamin D3 Companion: Vitamin D3 increases calcium absorption; vK2 ensures calcium is properly directed, making it an ideal partner for 5,000 IU vitamin D3 supplements.

*Vitamin K contributes to normal blood clotting and maintenance of normal bones (EFSA approved).

Understanding MK-4 and MK-7

MK-4, naturally found in animal foods like liver and egg yolks, has a short half-life of about one hour and is rapidly taken up by tissues, including the brain. MK-7, from bacterial fermentation (natto), has a half-life of around three days, providing steady blood levels. vK2's MK-4 is pharmaceutical grade with over 99% in the active trans configuration, while the MK-7 is 70% trans, sourced from trusted European suppliers. The natural yellow colour is a hallmark of high-purity vitamin K2—avoid white or off-white supplements as they may indicate lower quality.

Who Should Consider vK2?

Anyone taking vitamin D3 supplements should consider vK2 to ensure proper calcium routing. This includes individuals concerned about bone health as they age, those whose diet lacks K2-rich foods (natto, some cheeses), and those with fat malabsorption conditions or on long-term antibiotics. Always consult your GP or health care professional before starting a new supplement.

Choosing a Quality Vitamin K2 Supplement

When selecting a K2 supplement, consider the form (MK-4 vs MK-7), isomer purity (trans vs cis), and source. vK2 uses pharmaceutical-grade ingredients from European suppliers. With over 25 years in business and an A+ BBB rating, NHS Global Distributors prioritises quality. Each batch is manufactured in the USA under strict quality control.

How to Uses vK2

Take one capsule daily with a meal containing fat for optimal absorption. Each capsule contains 5 mg MK-4 and 100 mcg MK-7. Store in a cool, dry place. If you are taking blood-thinning medications such as warfarin, consult your doctor before uses, as vitamin K can interfere with their effect.

Frequently Asked Questions

Why combine MK-4 and MK-7?

MK-4 provides rapid, short-term activation of vitamin K-dependent proteins, while MK-7 offers sustained levels. Together, they cover both immediate and long-term needs for calcium regulation.

Can I take vK2 with my vitamin D3 supplement?

Yes, vK2 is specifically designed as a companion to 5,000 IU vitamin D3. It helps ensure calcium is directed to bones and teeth rather than soft tissues.
