Product Description
Vitamin K2 (also known as menaquinone) is a fat-soluble vitamin that plays a crucial role in various biological processes, including blood clotting, bone metabolism, and cardiovascular health. It is a part of the broader Vitamin K group, with Vitamin K1 (phylloquinone) being more widely known for its role in blood clotting. While Vitamin K1 is mainly found in plant-based foods, Vitamin K2 is primarily found in animal products and fermented foods.
Sources of Vitamin K2:
Vitamin K2 is mainly found in animal-based foods and fermented products. The most significant dietary sources of Vitamin K2 include:
- Natto (fermented soybeans): The richest known source of MK-7.
- Fermented dairy products: Such as cheese (especially aged cheeses like gouda), yogurt, and kefir.
- Egg yolks and liver (especially from grass-fed animals).
- Meat (especially chicken and beef liver).
- Butter (from grass-fed cows).
- Fermented foods: Sauerkraut, miso, and other fermented vegetables.
Vitamin K2 is a crucial nutrient for bone health, cardiovascular health, and overall well-being. It is found in a variety of animal-based foods and fermented products, with MK-7 from natto being the most studied and bioavailable form. Ensuring adequate intake of Vitamin K2 may help prevent conditions like osteoporosis, heart disease, and improve overall calcium metabolism.
