Understanding Vitamin K2 MK-4
Vitamin K2 is a group of compounds called menaquinones, with MK-4 (menaquinone-4) being one of the most studied forms. MK-4 is a short-chain menaquinone naturally found in animal foods such as grass-fed butter, egg yolks, and meat. Unlike MK-7, which is produced by bacteria and has a longer half-life, MK-4 is rapidly used by the body and is particularly concentrated in tissues like the brain, bones, and blood vessels. This supplement provides 100 mcg of MK-4 per capsule, enriched with alfalfa concentrate—a natural source of vitamins and minerals—to support overall nutrient intake.
Key Contributions of Vitamin K2
-
Bone Health: Vitamin K contributes to the maintenance of normal bones by activating osteocalcin, a protein that helps bind calcium to the bone matrix.*
-
Normal Blood Clotting: Vitamin K is essential for the production of clotting factors, thereby supporting normal blood coagulation.*
-
Calcium Metabolism: Through activation of matrix Gla-protein (MGP), vitamin K2 helps direct calcium to bones and teeth and away from soft tissues.*
-
Heart Health: By promoting proper calcium management, vitamin K2 may support cardiovascular wellness, although this is not an authorised health claim in the UK.*

Who Might Consider Supplementing?
This supplement may be beneficial for individuals with limited dietary intake of vitamin K2, those concerned about bone health, and people taking medications that affect K2 levels (e.g., certain antibiotics or anticoagulants—consult your health care provider). Older adults and postmenopausal women may also benefit from additional bone density support. Because MK-4 is rapidly utilised by the body, it may be suitable for those needing a short-acting, easily absorbed form of vitamin K2.
Recommended Uses
Take one capsule daily with a meal—preferably one containing fat, as vitamin K2 is fat-soluble for optimal absorption. Do not exceed the recommended dose unless advised by a health care professional. Store in a cool, dry place away from direct sunlight. Each bottle contains 200 capsules, providing a six-month supply at one per day.
Safety and Precautions
Vitamin K2 is generally well tolerated. However, individuals taking blood-thinning medications (such as warfarin) should avoid vitamin K supplements unless specifically directed by a physician, because K2 can interfere with anticoagulant therapy. Pregnant or nursing women should consult their doctor before uses. Keep out of reach of children.
