Vitamin K (Potassium)

Any of a group of vitamins found mainly in green leaves and essential for the blood-clotting process. They include phylloquinone ( vitamin K1) and menaquinone ( vitamin K2). Some studies suggest that it is important for promoting bone health. You can find it naturally in foods, such as: cabbage, cauliflower, dark green vegetables (broccoli, brussel sprouts, asparagus), dark leafy vegetables (spinach, kale, collards), fish, liver, beef, eggs, and in cereals. The Potassium’s main function is to make sure calcium goes only to your bones and not where it is not needed. Your body needs it to function normally. It is vital to the functioning of nerve and muscle cells.

Vitamin K is a vitamin found in leafy green vegetables, broccoli, and Brussels sprouts. The name vitamin K comes from the German word “Koagulationsvitamin.”

Several forms of vitamin K are used around the world as medicine. But in the U.S., the only form available is vitamin K1 (phytonadione). Vitamin K1 is generally the preferred form of vitamin K because it is less toxic, works faster, is stronger, and works better for certain conditions.

Effective for:

Treating and preventing vitamin K deficiency.
Preventing certain bleeding or blood clotting problems.
Reversing the effects of too much warfarin used to prevent blood clotting.

Insufficient Evidence for:

Weak bones (osteoporosis). So far, research results on the effects of vitamin K on bone strength and fracture risk in people with osteoporosis don’t agree.
Cystic fibrosis.
Heart disease.
High cholesterol.
Spider veins.
Stretch marks.
Other conditions.
More evidence is needed to rate vitamin K for these uses.

Vitamin K is safe for most people. Most people do not experience any side effects when taking in the recommended amount each day.

Special Precautions & Warnings:

Pregnancy and breast-feeding: When taken in the recommended amount each day, vitamin K is considered safe for pregnant and breast-feeding women, but don’t use higher amounts without the advice of your healthcare professional.

Kidney disease: Too much vitamin K can be harmful if you are receiving dialysis treatments due to kidney disease.

Liver disease: Vitamin K is not effective for treating clotting problems caused by severe liver disease. In fact, high doses of vitamin K can make clotting problems worse in these people.

In the body, vitamin K plays a major role in blood clotting. So it is used to reverse the effects of “blood thinning” medications when too much is given; to prevent clotting problems in newborns who don’t have enough vitamin K; and to treat bleeding caused by medications including salicylates, sulfonamides, quinine, quinidine, or antibiotics. Vitamin K is also given to treat and prevent vitamin K deficiency, a condition in which the body doesn’t have enough vitamin K. It is also used to prevent and treat weak bones (osteoporosis) and relieve itching that often accompanies a liver disease called biliary cirrhosis.

People apply vitamin K to the skin to remove spider veins, bruises, scars, stretch marks, and burns. It is also used topically to treat rosacea, a skin condition that causes redness and pimples on the face. After surgery, vitamin K is used to speed up skin healing and reduce bruising and swelling.

Major Interaction. Do not take this combination:

Warfarin (Coumadin) interacts with VITAMIN K
Vitamin K is used by the body to help blood clot. Warfarin (Coumadin) is used to slow blood clotting. By helping the blood clot, vitamin K might decrease the effectiveness of warfarin (Coumadin). Be sure to have your blood checked regularly. The dose of your warfarin (Coumadin) might need to be changed.

Healthcare providers also give vitamin K by injection to treat clotting problems.

An increased understanding of the role of vitamin K in the body beyond blood clotting led some researchers to suggest that the recommended amounts for dietary intake of vitamin K be increased. In 2001, the National Institute of Medicine Food and Nutrition Board increased their recommended amounts of vitamin K slightly, but refused to make larger increases. They explained there wasn’t enough scientific evidence to make larger increases in the recommended amount of vitamin K.
