Life Extension Super K, 150 Softgels - Vitamin K1 & K2 (MK-4 & MK-7)

Understanding Vitamin K: K1 and K2 Forms

Vitamin K is a group of fat-soluble nutrients essential for several bodily functions. The most common form, vitamin K1 (phylloquinone), is abundant in dark leafy greens and is crucial for normal blood clotting. The K2 family, including menaquinones like MK-4 and MK-7, helps regulate calcium distribution—directing it to the bones and away from soft tissues. Life Extension Super K combines all three key forms: K1, MK-4, and MK-7 (the latter derived from MenaQ7, a well-researched ingredient). This comprehensive blend supports bone density and maintains arterial flexibility.

What Does Each Form of Vitamin K Do?

Each form of vitamin K offers distinct benefits. Vitamin K1 (phytonadione) is primarily involved in blood coagulation. MK-4 (menaquinone-4) is naturally present in animal foods and contributes to bone metabolism. MK-7 (menaquinone-7) has a longer half-life and helps maintain calcium balance in the body. Together, they provide full-spectrum vitamin K support. Additionally, this formula contains ascorbyl palmitate (a form of vitamin C) to support antioxidant activity and vitamin E recycling.

Who May Benefit From Vitamin K Supplementation?

Anyone with a low intake of leafy greens, those taking anticoagulant medication (who should consult their GP), or individuals looking to support bone health as they age may benefit from this supplement. As vitamin K is fat-soluble, take one soft gel capsule daily with a meal containing fat for best absorption. Alternatively, follow the advice of your health care professional.

How to Choose a Quality Vitamin K Supplement

When selecting a vitamin K supplement, opt for brands that rely on clinically validated ingredients. Life Extension Super K uses MenaQ7 MK-7, a form with substantial research on bioavailability. These softgels are non-GMO and contain no unnecessary additives. Each bottle provides a 150-day supply (at one soft gel capsule per day). Store in a cool, dry place away from direct sunlight.

Are There Any Side Effects or Precautions?

Vitamin K supplements are generally safe for most people. However, if you are on anticoagulant therapy (e.g., warfarin), it is essential to speak with your GP before taking this product, as vitamin K may interact with these medications. Adhere to the recommended dosage and stop uses if you notice any unwanted effects.

Why Choose Life Extension Super K?

Many individuals fail to meet their vitamin K requirements through diet alone. Life Extension Super K addresses this gap by supplying a balanced combination of K1, MK-4, and MK-7 in a single, easy-to-swallow soft gel capsule. With 150 capsules per bottle, this non-GMO formula offers a full 150-day supply, making it a convenient choice for daily uses.
