Vitamin K

Vitamin K is a fat soluble vitamin that appears in several forms: the compounds are labeled K1, K2 and K3, with the latter being synthetic. The vitamin is extremely important in the function of blood clots. It is unique among vitamins, in that it is produced by bacteria in the intestines. However, the amount that is produced satisfies only half of the daily requirement and therefore a Vitamin K supplement may be needed to make up for the rest, and to ensure that a deficiency does not take place.

The ideal natural sources for Vitamin K include leafy green vegetables, kelp, alfalfa, egg yolk, cauliflower, soybean oil, kelp and liver. As stated, however, the main place where the vitamin originates is in the large intestine. Individuals who do not receive a sufficient intake of the vitamin in their diets may develop clotting problem, and therefore should consider taking Vitamin K supplements to remedy and any potential problems.

Vitamin K works in the liver to synthesize the protein prothrombin, eventually converting it through a series of steps with other proteins into a blood clot. The vitamin’s effectiveness in this capacity also enables it to aid in reducing internal bleeding and hemorrhages, and can also help with menstrual cramps. Some recent studies indicate the vitamin may reverse the onset of bone loss through osteoperosis, by enabling the body to better absorb the mineral calcium.

As a matter of fact, one of the primary signs of a deficiency of Vitamin K is osteoperosis and prolonged bleeding times. Other symptoms include heavy menstrual bleeding, gum bleeding, nosebleeds and hematuria, which is blood in the urine. Individuals who take anti-coagulant drugs should check with their doctors before choosing to add Vitamin K supplements to their daily regimen. One of the most commonly prescribed oral anti-coagulants, for example, is the drug Coumadin, which directly counteracts the effects of the vitamin. Additionally, individuals who take antibiotics may experience a deficiency since the antibiotic may destroy the flora in the intestines, where the vitamin is created.

For supplementation, only about 1 mcg per kilogram of body weight is needed to prevent problems clotting. Accordingly, the recommended daily dosage for adults has been set between 65-80 mcg. The vitamin relies on calcium and vitamin D to increase its efficacy, and therefore any Vitamin K supplements should include a complete formula that contains all of these nutrients, and is certified as pharmaceutical GMP compliant to ensure compliance with the most exacting scientific standards for production.
