Vitamin K is a fat-soluble vitamin that plays a fundamental role in many of the body's vital functions. Essential for blood clotting, bone health and the regulation of calcium levels, it is also recognized for its benefits to cardiovascular health. Although present in the diet, this vitamin can be supplemented with food supplements to meet specific individual needs.
Vitamin K comes in two main forms: vitamin K1, or phylloquinone, and vitamin K2, or menaquinone. The former is mainly found in plant-based foods such as green vegetables, while the latter is produced by intestinal bacteria and is present in animal products such as eggs, liver and fermented dairy products.
These two forms, though slightly different, play complementary roles in the body. Vitamin K1 is mainly involved in blood clotting, while vitamin K2 is more effective in bone health and the prevention of cardiovascular disease, thanks to its ability to regulate calcium binding.
Vitamin K is essential for a number of reasons. Firstly, it contributes to the formation of blood clots, a vital mechanism that helps stop bleeding in the event of injury. Without it, the clotting process would be inefficient, which could lead to dangerous bleeding. It also activates specific proteins that bind calcium in the bones, giving them strength and density.
Vitamin K also plays an important role in the prevention of cardiovascular disease. It acts by preventing the deposition of calcium in the arteries, a phenomenon which can lead to their hardening, thus increasing the risk of heart disease. It also has anti-inflammatory properties, promoting better general health and a stronger immune system.
Vitamin K is present in a wide range of foods, which means that a balanced diet can generally cover daily requirements. Leafy green vegetables such as spinach, kale and broccoli are among the best natural sources of vitamin K1. As for vitamin K2, it can be found in fermented foods such as natto (a soy-based product) and cheese, as well as in animal products such as liver and egg yolks.
However, dietary intakes can sometimes be insufficient, especially for people with unbalanced diets or digestive disorders. In such cases, dietary supplements are an effective option for ensuring optimal intake.
Vitamin K deficiency is relatively rare in adults, but can occur in certain specific situations. For example, newborns, who are born with very low reserves of this vitamin, are particularly at risk. People suffering from chronic diseases affecting fat absorption, such as Crohn's disease, may also be deficient.
Signs of deficiency include prolonged bleeding, even from minor injuries, and increased bone fragility, leading to a higher risk of fractures. In the long term, deficiency can also contribute to calcification of the arteries, increasing cardiovascular risk.
Dietary supplements can be particularly useful for people with increased needs or difficulties in obtaining sufficient vitamin K from their diet. This includes the elderly, who are often prone to reduced bone density, or those taking medications that interfere with the absorption of fat-soluble vitamins.
Vitamin K2-based supplements are generally preferred because of their better absorption and greater effectiveness in supporting bone and cardiovascular health. They can be easily integrated into your daily routine, particularly by taking them with a high-fat meal to maximize their bioavailability.
Before starting vitamin K supplementation, it's essential to consult a healthcare professional, especially if you're taking anticoagulants or other medications. Vitamin K can interfere with these treatments, necessitating dose adjustment or specific medical monitoring.
To increase your vitamin K intake naturally, opt for meals rich in green vegetables such as spinach, cabbage or broccoli. Add eggs, fermented dairy products and foods such as liver to your meals to benefit from vitamin K2. A varied and balanced diet remains the key to meeting your body's nutritional needs.
Vitamin K is an essential nutrient that plays a central role in blood clotting, bone strengthening and cardiovascular protection. While most people can get enough vitamin K from their diet, dietary supplements can be a practical and effective solution to meet specific needs.
