Vitamin K2 is an essential nutrient that plays a crucial role in maintaining bone and heart health. It is a fat-soluble vitamin that is found in various animal and plant-based foods. In recent years, the benefits of vitamin K2 have gained more attention as studies have shown its vital role in preventing various chronic diseases.
What is Vitamin K2?
Vitamin K2, also known as menaquinone, is a group of compounds that are found in animal and plant-based foods. The most common form of vitamin K2 is menaquinone-4, which is found in animal products such as meat, eggs, and dairy. On the other hand, menaquinone-7 is found in fermented foods such as sauerkraut and natto.
Importance of Vitamin K2 for Bone Health
Vitamin K2 plays a crucial role in maintaining bone health. It helps in the activation of osteocalcin, a protein that is responsible for binding calcium to the bone matrix. Without vitamin K2, calcium cannot be effectively utilized, leading to weaker bones and an increased risk of fractures.
Studies on Vitamin K2 and Bone Health
Several studies have shown the positive effects of vitamin K2 on bone health. A study conducted on postmenopausal women found that those who took vitamin K2 supplements had a significant increase in bone mineral density compared to those who did not take the supplements. Another study found that vitamin K2 supplementation reduced the risk of fractures in older women.
Importance of Vitamin K2 for Heart Health
Vitamin K2 also plays a vital role in maintaining heart health. It helps in preventing the buildup of calcium in the arteries, which can lead to atherosclerosis, a condition that increases the risk of heart disease.
Studies on Vitamin K2 and Heart Health
Several studies have shown the positive effects of vitamin K2 on heart health. A study conducted on older men found that those with higher levels of vitamin K2 had a lower risk of developing coronary heart disease. Another study found that vitamin K2 supplementation improved arterial stiffness in postmenopausal women.
Food Sources of Vitamin K2
Vitamin K2 is found in various animal and plant-based foods. The best sources of vitamin K2 are fermented foods such as natto, sauerkraut, and cheese. Other sources of vitamin K2 include meat, eggs, and dairy products.
