Natural Factors - Vitamin K2 120 mcg

Essential Vitamin for Bone and Cardiovascular Health

Natural Factors Vitamin K2 delivers 120 mcg of menaquinone-7 (MK-7), the most bioactive and longest-lasting form of vitamin K2. While vitamin K1 is primarily involved in blood clotting, vitamin K2 plays critical roles in directing calcium to your bones and teeth where it belongs—and away from your arteries and soft tissues where it can cause harm. This essential nutrient supports bone density, cardiovascular health, and proper calcium metabolism for optimal skeletal and circulatory wellness.

Key Benefits

• 120 mcg of vitamin K2 (MK-7) – The most bioavailable form with superior absorption and longer half-life in the body
• Supports bone health and density – Activates osteocalcin, the protein that binds calcium to bone matrix for stronger, healthier bones
• Promotes cardiovascular health – Activates matrix Gla-protein (MGP) to help prevent calcium deposits in arteries and soft tissues
• Optimizes calcium metabolism – Ensures calcium is directed to bones and teeth, not arteries
• Complements vitamin D and calcium – Works synergistically with these nutrients for comprehensive bone and heart support
• Supports healthy blood clotting – Plays a role in the synthesis of clotting factors for normal wound healing

Why Vitamin K2 (MK-7)?

Vitamin K2 exists in several forms, but MK-7 (menaquinone-7) is considered the gold standard due to its superior bioavailability and extended half-life in the body. Unlike vitamin K1, which is rapidly cleared from the bloodstream, MK-7 remains active for up to 72 hours, providing sustained support for bone and cardiovascular health. MK-7 is also more effective at activating vitamin K-dependent proteins throughout the body, making it the preferred form for therapeutic supplementation.

The Calcium Paradox

Many people take calcium and vitamin D for bone health, but without adequate vitamin K2, calcium may not end up where it's needed. Vitamin K2 activates two critical proteins: osteocalcin, which binds calcium to bones, and matrix Gla-protein (MGP), which prevents calcium from depositing in arteries and soft tissues. This dual action helps solve the "calcium paradox"—ensuring strong bones while supporting cardiovascular health.

Who It's For

Vitamin K2 is ideal for adults seeking to support bone density and strength, maintain cardiovascular health, or optimize calcium metabolism. It's particularly beneficial for postmenopausal women, older adults at risk for osteoporosis, those taking calcium and vitamin D supplements, or anyone looking to support long-term skeletal and circulatory wellness.

Suggested Use

Take 1 softgel daily with a meal containing fat for optimal absorption, or as directed by a healthcare practitioner. For best results, use in combination with vitamin D3 and calcium.

Important Note

If you are taking blood-thinning medications (such as warfarin), consult your healthcare practitioner before using vitamin K2, as it may affect blood clotting.
