vitamiinK

Vitamiin K is a fat-soluble vitamin that plays a crucial role in blood clotting and bone metabolism. It exists in several forms, with vitamin K1 (phylloquinone) and vitamin K2 (menaquinones) being the most common in humans. Vitamin K1 is primarily found in green leafy vegetables such as spinach, kale, and broccoli. Vitamin K2 is produced by bacteria in the gut and also found in fermented foods like natto and certain cheeses.

The body requires vitamin K for the synthesis of proteins essential for blood coagulation, preventing excessive bleeding. It also contributes to bone health by facilitating the incorporation of calcium into bones and regulating calcium levels in the blood. Deficiency in vitamin K is rare in healthy adults but can occur in newborns, individuals with malabsorption disorders, or those on certain medications. Symptoms of deficiency can include easy bruising and prolonged bleeding. Maintaining adequate intake through a balanced diet is generally sufficient for most individuals.
