Vitamin K2 (MK4)

Sinonimi: Menaquinone-4, Vitamin K2, MK-4, Menatetrenone, 2-Methyl-3-all-trans-tetraprenyl-1,4-naphthoquinone, Vitamin K2 (MK4)

Vitamin K2 (MK4) has become a key ingredient for formulators targeting bone and cardiovascular health. Unlike the more common MK-7, MK-4 is a short-chain menaquinone with a distinct pharmacokinetic profile—rapid absorption and quick tissue distribution. Its popularity surged after Japan approved menatetrenone for osteoporosis treatment, and it now appears in premium bone health supplements, cardiovascular support formulas, and functional foods.

Chemically, MK-4 is a naphthoquinone with a four-unit isoprenoid side chain. It occurs naturally in animal products like egg yolk, liver, and butter, but commercial production relies on chemical synthesis to achieve high purity. At LyvBio, we supply synthetic MK-4 with ≥98% purity (HPLC), ensuring consistent quality for your formulations.

Product Overview & Composition

Vitamin K2 (MK4) is a fat-soluble vitamin essential for activating osteocalcin and matrix Gla protein, which regulate calcium deposition in bones and arteries. Its mechanism involves gamma-carboxylation of glutamate residues in these proteins, enhancing their calcium-binding capacity. This makes MK-4 particularly valuable for bone mineral density and arterial elasticity.

Our MK-4 is synthesized through a multi-step process, yielding a crystalline powder that is standardized to ≥98% purity. It is available in various packaging sizes to suit your production needs.
