Product Description

Product Description

Vitamin K2, particularly in the form of Menaquinone-4 (MK-4), is a fat-soluble vitamin known for its critical roles in blood coagulation, bone metabolism, and maintaining overall health. MK-4 is predominantly found in animal-derived foods such as butter and egg yolks, and it has been the subject of research for its potential therapeutic effects, particularly in the treatment of rheumatoid arthritis (RA). Studies have indicated that MK-4 can reduce the proliferation of rheumatoid synovial cells, with a daily intake of 45 mg demonstrating a reduction in clinical and biochemical markers of disease activity.

Application

Vitamin K2 as MK-4 has been utilized in supplement form to support bone health and may contribute to the prevention or alleviation of conditions like cardiovascular disease, osteoporosis, and inflammatory diseases. The production of MK-4 involves a complex biosynthetic pathway, which includes the shikimate pathway for chorismate production and the mevalonate (MVA) or 2-C-methyl-d-erythritol-4-phosphate (MEP) pathway for the isoprene side chain. Metabolic engineering strategies have been employed to enhance MK-4 production, such as overexpression of key enzymes and optimization of precursor supply.
