Health Benefits of Vitamin K2

Vitamin K2 is widely recognized for its role in bone metabolism by activating osteocalcin, a protein that binds calcium to the bone matrix. This can contribute to maintaining strong, healthy bones as you age. Additionally, K2 supports cardiovascular health by activating matrix Gla-protein (MGP), which helps inhibit arterial calcification. By promoting proper calcium distribution, vitamin K2 helps maintain both skeletal integrity and vascular flexibility.

What is Vitamin K2 (MK-7)?

Vitamin K2, also known as menaquinone, is a fat-soluble vitamin essential for bone and cardiovascular health. The MK-7 form (menaquinone-7) is derived from natural sources like natto (fermented soybeans) and is recognized for its superior bioavailability and longer half-life compared to other forms of vitamin K. NOW Foods delivers 100 mcg of MK-7 per vegan capsule, providing a convenient way to support your body's natural processes.

Vitamin K1 vs K2: What’s the Difference?

Vitamin K exists in two primary forms: K1 (phylloquinone) and K2 (menaquinone). K1 is mainly found in green leafy vegetables and plays a critical role in blood clotting. K2, on the other hand, is more involved in directing calcium to the bones and teeth while preventing calcium buildup in arteries and soft tissues. Within K2, MK-7 is the most studied and effective subtype due to its long circulation time in the blood, allowing for steady support throughout the day.

How Much Vitamin K2 Should You Take?

The adequate intake for vitamin K varies by age and gender, but a typical maintenance dose of K2 (MK-7) ranges from 45 to 100 mcg per day. Each capsule of NOW Foods MK-7 provides 100 mcg, which aligns with common supplementation guidelines. For optimal absorption, take with a meal containing fat, as vitamin K is fat-soluble. Always consult your healthcare provider before starting any new supplement regimen, especially if you are taking blood-thinning medications.

Potential Side Effects and Interactions

Vitamin K2 is generally well-tolerated with few side effects. However, individuals on anticoagulant therapy (e.g., warfarin) should avoid vitamin K supplements unless specifically directed by a physician, as vitamin K can interfere with these medications. Mild digestive upset may occur in sensitive individuals. As with any supplement, it is important to follow the recommended dosage and seek medical advice if you have underlying health conditions.

Frequently Asked Questions

Can I take Vitamin K2 with Vitamin D? Yes, vitamin D and K2 often work synergistically. Vitamin D helps increase calcium absorption, while K2 directs it to the bones. Many people take them together for comprehensive bone support.

Is MK-7 safe for long-term use? MK-7 has a strong safety profile and is suitable for long-term supplementation at recommended doses. However, if you have any medical conditions or take medications, consult your healthcare provider.

Do I need Vitamin K2 if I eat a healthy diet? While green vegetables provide K1, dietary sources of K2 are limited (e.g., natto, certain cheeses). A supplement can help ensure adequate intake, especially for bone and heart health as you age.
