Vitamin K | Frenly Beauty

Vitamin K, a fat-soluble vitamin, is crucial for blood coagulation and bone metabolism. It exists in two primary forms: K1 (phylloquinone), found in leafy green vegetables, and K2 (menaquinones), produced by bacteria and found in fermented foods and animal products. While K1 is primarily involved in liver-based clotting factor synthesis, K2 plays a significant role in directing calcium to bones and away from arteries, potentially reducing the risk of osteoporosis and cardiovascular disease. Despite its importance, deficiency is not uncommon, especially in infants and individuals with malabsorption issues, leading to increased bleeding risk and potentially weaker bones. The debate continues regarding optimal intake levels and the relative benefits of K1 versus K2 for long-term health.
