Dr. Mercola Vitamin K2 180 mcg as MK-7 - Supports Healthy Arterial Function & Heart Health - Non-GM, Gluten-Free & Soya-Free - 90 Capsules (90 Servings)

Understanding Vitamin K2 and Its Importance

Vitamin K2, or menaquinone, is a fat-soluble vitamin essential for calcium metabolism. While vitamin K1 (phylloquinone) is primarily known for its role in blood clotting, K2 ensures calcium is deposited in bones and teeth rather than accumulating in soft tissues such as arteries. This particular supplement provides 180 mcg of vitamin K2 in the MK-7 form, which is noted for its superior bioavailability and sustained activity. Sourced from natto fermented from chickpeas, this formula is soya-free and non-GM.

Distinguishing Vitamin K2 from Vitamin K1

Whilst both forms of vitamin K are vital, they perform different functions. Vitamin K1, abundant in green leafy vegetables, is crucial for clotting. Vitamin K2, produced by bacteria and present in fermented foods, has a longer half-life due to the MK-7 subtype, ensuring more stable blood levels. This supplement contains MenaQ7, a patented MK-7 that has been thoroughly researched for its capacity to activate matrix Gla protein (MGP) and osteocalcin—proteins that govern calcium deposition. Selecting K2 over K1 offers targeted benefits for bone and cardiovascular health.

Key Health Benefits of Vitamin K2

• Supports Heart Health: Vitamin K2 activates MGP, which helps prevent calcium build-up in arterial walls, thereby promoting healthy arterial function.*
• Strengthens Bones: By activating osteocalcin, K2 facilitates calcium binding to the bone matrix, helping to maintain bone density and strength.*
• Improves Calcium Utilisation: Vitamin K2 directs calcium to the bones and teeth, minimising soft tissue accumulation.*
• Works Synergistically with Vitamin D3: Many experts advise combining K2 with vitamin D3 for optimal calcium metabolism. (This product is standalone; consider pairing with a D3 supplement.)

Optimal Dosage and Usage Recommendations

Each capsule supplies 180 mcg of vitamin K2 as MK-7, a dose aligned with clinical research for bone and cardiovascular support. The recommended intake is one capsule daily, preferably with a meal containing fat to aid absorption. As with any supplement, consult your health care professional to determine the appropriate dosage for your individual needs, particularly if you are taking anticoagulant medication.

Considerations for Side Effects and Interactions

Vitamin K2 is generally well tolerated at recommended doses. However, high intakes may interfere with anticoagulant medicines such as warfarin. If you are on blood thinners, speak to your doctor before uses. Some individuals may experience mild digestive discomfort. Always adhere to the recommended dosage and keep out of reach of children.
