Vitamin K3

Vitamin K3, chemically known as Menadione, is a synthetic, fat-soluble vitamin used primarily in animal nutrition and some pharmaceutical applications. Unlike Vitamins K1 and K2, Vitamin K3 does not occur naturally but is a stable precursor that the body (or animal body) can convert into active forms of Vitamin K. It plays a critical role in blood clotting, bone metabolism, and cellular health. Vitamin K3 is usually available as Menadione Sodium Bisulfite (MSB) or Menadione Nicotinamide Bisulfite (MNB) for enhanced solubility and stability.
