Life Extension Super K 150 Softgels - Daily K1 & K2 Support

In this review of Life Extension Super K, the bottom line is simple: it is a convenient daily vitamin K formula for people seeking broad K nutrient support without complicated dosing. The reviewer finds it especially useful for adults who want both K1 and the two common K2 forms (MK-4 and MK-7) in a single softgel, plus a small amount of vitamin C to aid stability. One softgel a day delivers a high total of vitamin K compounds and comes in a 150-day bottle, making it an easy choice for long-term maintenance.

Key Features

• Once-daily dosing: Taking one softgel with food makes it simple to incorporate into a daily routine without multiple pills.
• Broad K spectrum: Contains vitamin K as phytonadione plus K2 as MK-4 and MenaQ7 MK-7, providing the common dietary forms of vitamin K in one supplement.
• Vitamin C added: Each softgel contains 10 mg of vitamin C as ascorbyl palmitate, which can help support antioxidant protection of fat-soluble nutrients.
• Long supply: A single bottle provides a 150-day supply when taken as directed, reducing how often refills are needed.
• Small, easy-to-swallow softgels: The softgel size is generally small, making ingestion straightforward for most users.

Who It's For

This supplement is aimed at adults looking for comprehensive vitamin K support from a single, once-daily softgel. It suits people who prefer a combination product that includes both K1 and the common K2 forms MK-4 and MK-7, and who value a long supply per bottle to avoid frequent repurchasing.

Those who require extremely specific therapeutic dosing or wish to avoid any added vitamin C should consult a healthcare practitioner or choose a more narrowly targeted formula. Also, anyone with a condition requiring tight medical supervision of vitamin K intake should check with their provider before using this product.
