Vitamin K is important as it helps the blood to clot. The 'K' comes from the German word Koagulation, which literally means 'to clot'. Vitamin K can also contribute towards maintaining healthy bones.
How much Vitamin K do I need?
Vitamin K needs change dependent on a person's weight. Adults need approximately 1mcg a day of vitamin K for each kilogram they weigh. A really simple example would be, someone who weighs 55kg would need 55mcg of vitamin K a day, while a person who weighs 70kg would need 70mcg a day. Any vitamin K that the body doesn't use is stored in the liver for future use by the body, so there's no need to consume vitamin K rich food on a daily basis.
Vitamin K deficiency in babies
Vitamin K deficiency is quite common in new born babies, who are usually born with low levels of the vitamin. A single dose of vitamin K is usually given to most new born babies as low levels of vitamin K can give rise to a rare, but serious condition called 'vitamin K deficiency bleeding' (VKDB). Babies don't get enough vitamin K from their mothers during pregnancy, and VKBD can cause bleeding on the brain. In the UK, the HCP normally offer an injection of Vit K to newborn to prevent this blood disorder.
Vitamin K deficiency in adults
It's rare for adults to be deficient in vitamin K, as the vitamin is easily obtained through a healthy, varied diet. Any excess vitamin K not required by your body is stored in the liver for future use. Vitamin K is not usually used as a standalone dietary suplement, but it can be found in Seven Seas Perfect 7 Man.
What are good sources of Vitamin K?
Good sources of vitamin K include green leafy vegetables such as lettuce, kale, mustard greens, parsley, spinach, Swiss chard and turnip greens, as well as vegetables such as broccoli, Brussel sprouts, cauliflower and cabbage. It's also possible to obtain vitamin K from sources that are less rich in the vitamin. Foods such as meats, fish, liver, eggs and cereals can also be beneficial.
Interactions with Vitamin K
There are a few commonly taken medications that can interfere with the effects of vitamin K such as antacids and blood thiners such as Warfarin. In fact, vitamin K is given to counteract excessive amounts of Warfarin in the body.
There are two types of vitamin K: K1 and K2. K1 is the prevailing source through diet, it is then converted to K2 in the body.
