Vitamin k2 - A Review

Vitamin K1 (phylloquinone), K2 (menaquinone), and K3 (phylloquinone) are the three types of vitamin K. (menadione). Vitamin K2 is found in both tissue and bacterial products (animal products or fermented foods). Vitamin k2 has nine chemical variations, with the number of isoprenyl units in their side chains determining the majority of them. The most frequent form of vitamin k2 in the human diet is the short chain, water soluble menatetrenone, which is generated by bacterial conversion of vitamin k1, as well as a tissue derivative (MK-4).MK-7, MK-8, and MK-9 are long-chain menaquinones (longer than MK-4) that are more prevalent in fermented foods like natto, a traditional Japanese meal prepared from soya beans fermented with bacillus subtilis var. Anaerobic bacteria in the colon create longer-chain menaquinones (MK-10 to MK-13), but they are poorly absorbed and have minimal physiological impact at this level. The effects of vitamin K2 on overall dentistry are the topic of this review
