Life Extension Super K – 90 softgels
★★★★— BarefooterThis brand seems like a good choice, in my opinion. I prefer this vitamin K to other brands I have used. I really like that they are capsules rather than dry capsules.
Read all 16 reviews →★★★★★— AnonymLife Extension's Super K is one of the best vitamin K blends I have tried. The combination of K1, MK-4 and MK-7 makes it exceptionally well balanced, and the capsules are small, smooth and easy to take. I trust the quality that Life Extension delivers, and this product is no exception. Since adding Super K to my routine, I feel better supported in terms of circulation, bone health and general wellbeing. The bottle of 90 capsules is good value and lasts a long time. Highly recommended to everyone.
Super K from Life Extension combines K1 and two bioactive K2 forms in soft capsules – gluten-free and non-GMO.

Product Overview
Life Extension Super K is a carefully formulated food supplement in softgel form, combining three forms of vitamin K to provide a broad spectrum of nutritional support. Each pack contains 90 softgels, providing a long-lasting supply for daily use. Life Extension is a brand with over 40 years of experience in nutritional research, known for prioritising scientifically based formulations and high-quality ingredients. Its philosophy is to provide products that are both effective and transparent in their contents, giving consumers a reliable and considered supplement.
Super K is intended for people who want to supplement their vitamin K intake, particularly with forms that can be difficult to obtain from the diet, such as K2. The product is gluten-free and certified non-GMO, making it suitable for a broad range of people with different dietary needs.
Active Ingredients & Science
Life Extension Super K contains three important forms of vitamin K. Vitamin K1 (phytonadione) is the naturally occurring form found in green leafy vegetables and plays a fundamental role in the body's functions. Vitamin K2 is provided as menaquinone-4 (MK-4), a short-chain form that is rapidly absorbed and distributed throughout the body, and MenaQ7® trans-menaquinone-7 (MK-7), a long-chain, patented form derived from fermented soya that remains in the body for longer. Combining these forms provides broad bioavailability and different durations of action in the body. The product also contains a small amount of vitamin C as ascorbyl palmitate to complement its nutritional profile.
Benefits & Uses
- Suitable for anyone wishing to supplement their vitamin K intake with several forms in one product.
- Suitable for people who find it difficult to obtain vitamin K2 from their diet, such as vegetarians or vegans.
- Useful for everyday use by those seeking a simple and effective softgel supplement that is easy to swallow.
- A practical choice for anyone seeking a gluten-free, certified non-GMO option.
The product's formulation makes it relevant for adults of different ages who want to ensure a consistent intake of vitamin K, without having to worry about missing different forms or their optimal absorption.
