Review Summary

This is the summary of consumer reviews for Life Extension Super K with Advanced K2 Complex Softgels. The BoolPool rating for this product is Very Good, with 4.40 stars, and the price range is $17.95-$24.99 (90 Count).

Life Extension Super K with Advanced K2 Complex Softgels, is a combination of three forms of Vitamin K (Vitamin K1, Vitamin K2 as MK-4 and Vitamin K3 as MK-7) that the human body can utilize to promote arterial health and bone support. Life Extension Super K with Advanced K2 Complex plays a critical role in maintaining healthy bone density by facilitating the transport of calcium from the bloodstream into the bones. These softgels are small and easy to take/swallow. They help in reduction of blood clotting, appearance of vein and frequent bruises. This product contains no milk, egg, fish, peanuts, crustacean shellfish (lobster, crab, and shrimp), soybeans, tree nuts, wheat, yeast, gluten, corn or rice. It also does not contain sugar, artificial sweeteners, flavors, colors or preservatives.

However, this supplement is not recommended for individuals who are estrogen sensitive. Though it claims it does not contain tree nuts or soybeans, MK-7 is made from natto, which is fermented soybeans, which again might not be suitable for users. Some users also feel pain and soreness in breast due to this. It is also believed that Life Extension products are not GMO-free and are usually overpriced.

Overall, Life Extension Super K with Advanced K2 Complex Softgels, are recommended by many users as a good dietary supplement to compensate Vitamin K deficiency which is usually hard to get in regular meals. It helps in maintaining arterial health, strong and healthy bones.
