Top 10 Benefits of Vitamin K

Vitamin K is an essential nutrient with many unique health benefits. Named for its role in coagulation (from the Danish word koagulation), this vitamin is essential in regulating blood clotting. Most of its benefits relate to blood, but there are several others as well. Let’s examine just ten of vitamin K’s immense health benefits.

1. Protects the heart

In order for the heart to function properly, its walls must be elastic so blood can flow through it easily. Vitamin K prevents the calcification, or hardening, of the heart’s walls, thereby preventing heart attacks and arterial disease.

2. Strengthens bones

Normally calcium is the primary nutrient associated with strong bones, so it may come as a surprise that vitamin K promotes the structural integrity of the bones. However, this vitamin does work in tandem with calcium, ensuring that it is properly absorbed and utilized to prevent fractures.

3. Promotes dental health

Vitamin K is a fat-soluble vitamin that maintains healthy teeth and gums. This vitamin protects against tooth decay by nullifying acids present in the mouth that would eat away at the enamel and structure of the teeth.

4. Prevents hemorrhage

Hemorrhages can occur at any age, but they are especially dangerous in infants and the elderly. Supplementation of vitamin K in pregnancy and old age prevents hemorrhaging that could possibly lead to death by increasing the efficiency of blood coagulation.

5. Boosts immunity

This vitamin gives the immune system a boost, preventing pathogens from entering the body and killing those that do, thereby protecting the body against numerous diseases. It has also been shown to maintain proper cardiovascular and digestive function.

6. Fights cancer

The antioxidants found in vitamin K put up a fierce resistance to carcinogens and free radicals that lead to the birth, growth, and spread of cancer cells. This vitamin has been shown to stabilize the condition of those with liver cancer, and it is known to prevent cancers of the stomach, prostate, and colon.

7. Speeds healing

Perhaps its most famous benefit, vitamin K speeds the healing of open cuts and wounds by speeding the process of clotting. Without this process, we would experience a condition similar to that experienced by hemophiliacs: a simple paper cut could cause an immense loss of blood. Coagulation also allows a scab to form more quickly, thus preventing bacteria from entering the body.

8. Prevents internal bleeding

This coagulation also aids in stopping internal bleeding, particularly in the liver and gastrointestinal tract. Overuse of antibiotics can cause internal bleeding, and while medical attention should always be sought in such a scenario, vitamin K can lessen the damage of that condition.

9. Relieves nausea

Many pregnant women experience nausea and morning sickness, and in rarer cases, a more severe condition known as hyperemesis gravidarum. Increased intake of vitamin K has been shown to reduce nausea and can play a role in preventing more serious conditions during pregnancy.

10. Prevents biliary obstruction

Long-term antibiotic use may cause biliary obstruction, which is a blockage of the bile ducts, as well as celiac disease and colitis. Vitamin K is known to treat symptoms of antibiotic overuse and can reduce the risk and side effects of these conditions.
