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.*

Choosing a High-Quality Supplement

biophix Vitamin K2 MK-4 is manufactured in the USA in an FDA-registered, GMP-certified facility, ensuring strict quality standards for purity, potency, and safety. The formula is vegetarian and vegan-friendly, with no animal-derived ingredients. Each capsule delivers a precise 100 mcg dose of MK-4, and the addition of alfalfa provides complementary phytonutrients. The product is backed by a 100% satisfaction guarantee, so you can try it with confidence.

Supporting Bone and Immune Health

Vitamin K2 is a vital nutrient that helps direct calcium to your bones and away from soft tissues—helping maintain strong bones and a healthy immune system. biophix Vitamin K2 MK-4 100 mcg combines the bioactive MK-4 form with alfalfa concentrate in a convenient vegetarian capsule. Each bottle provides 200 servings, making it easy to integrate into your daily wellness routine.

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.
