This recommended vitamin K2 intake applies regardless of whether or not it is taken together with vitamin D3, so even if you aren't taking a vitamin D supplement you should still maintain the above dosage of vitamin K2.

People who have early indications of cardiovascular disease or osteoporosis can also take the higher dose to ensure that all the body's matrix Gla proteins (MGPs) are activated.Ĥ5mcg of vitamin K2 a day is generally enough for healthy people under the age of 50, but this recommendation only applies if there is no additional vitamin D3 intake from dietary supplements.Īnyone who wants to ensure an optimal supply and guarantee that all vitamin K2-dependent proteins are activated in the body should take at least 100mcg. The higher dosage of 200mcg is especially recommended for people who have a history of cardiovascular disease or osteoporosis in their families.

Professor Vermeer of the University of Maastricht thus recommends that people aged over 50 take a dosage of 100 to 200mcg vitamin K2 per day. People over the age of 50 are particularly vulnerable to cardiovascular disease and osteoporosis, but it is precisely at this age that the diet often contains even less vitamin K and the skin's exposure to sunlight is also severely limited, thus leading to deficiencies in vitamin K and vitamin D.

There is clear evidence that vitamin K intake is too low in Western civilisation. The optimum dose of vitamin K2Īs the intestines only produce small quantities of vitamin K, we have to provide a supply from foods or supplements that are rich in vitamin K. Vitamin D and K2 work together to strengthen bones and promote the health of the heart and arteries. These proteins have many health benefits, but cannot be activated if insufficient vitamin K2 is available, so anyone who is taking vitamin D needs more vitamin K2. Taking vitamin D stimulates the body to produce more of the vitamin K2-dependent proteins that transport calcium. in the arteries and other soft tissue of the body. It also prevents calcification, the accumulation of calcium in places where it is not required - i.e. This important vitamin is responsible for depositing calcium at the right places in the body - i.e. Anyone who regularly takes vitamin D as a dietary supplement also needs to take vitamin K2.
