Vitamin K was also discovered by dentist Weston Price, who traveled the world in the early part of the 20th century to study and study the link between diet and disease in different territories. He realized that in countries with less-developed industries, people’s diets contain an unknown nutrient with relatively high content that helps prevent the formation of dental plaque and diseases. chronic reason. He calls this mysterious nutrient the activating factor X (the original name is “activator X”), which is today’s vitamin K2.

Another study conducted on 16057 women also found that those who took a diet high in vitamin K2 had a reduced risk of cardiovascular disease. With the daily intake of vitamin K2 at 10 micrograms, the risk of cardiovascular diseases is reduced by 9%.

2.2 Improve bone health and reduce the risk of osteoporosis

Vitamin K2 plays a central role in the metabolism of calcium, the main micronutrient in human bones and teeth. Vitamin K2 activates the calcium-binding proteins osteocalcin and GLA that help build bones and maintain firmness. A three-year study of 244 menopausal women found that taking vitamin K2 supplements slowed down the process of reducing bone mineral density due to aging. In addition, vitamin K supplements are officially recommended for the prevention and treatment of osteoporosis in Japan.

Many studies have been done to find a link between vitamin K2 and certain types of cancer. Two clinical studies suggest that vitamin K2 reduces the recurrence of liver cancer and prolongs life. Moreover, an observational study of 11,000 men found that high levels of vitamin K2 supplementation were associated with a reduced risk of prostate cancer while vitamin K1 did not have this effect. However, there is still a need for quality studies before concluding on this effect of vitamin K in general and vitamin K2 in particular.

3. Foods that contain vitamin K2

  • The gut bacteria are responsible for synthesizing vitamin K2 in the colon and converting vitamin K1 into vitamin K2 but the conversion rate is very low and this conversion is not nearly enough to meet the body’s needs.
  • However, there are other foods rich in vitamin K2 such as animal products, meat, eggs, and fermented foods like cheese, yogurt, natto – a traditional Japanese food. Fermented vegetables are a good source of vitamin K2. Note: Not all bacteria produce vitamin K2, so not all fermented foods contain this vitamin.
