Vitamin K is an essential fat-soluble nutrient that comes in two forms, K1 and K2. K1 comes from plants especially leafy green vegetables while K2 is naturally created in the intestinal duct and works similarly to K1. It was named so, not because of alphabetic order but because the Danish researcher who discovered that it prevented chickens on a fat-free diet from bleeding out called it the “koagulation vitamin” using the German spelling of coagulation. Hence, vitamin K.

General benefits of vitamin K

Bone and teeth health: There appears to be a correlation between low intake of vitamin K and osteoporosis. It supports the maintenance of strong bones, improves bone density, and decreases the risk of fractures. Health: Tips For Stronger Bones And Teeth

Helps with blood coagulation: It is needed to manage proteins involved in blood clotting and works to keep you from bleeding to death when you get a cut. If you don’t get enough vitamin K, your blood does not clot when it needs to and you could experience haemorrhaging which is excessive bleeding from a wound.

Reduces excessive menstrual flow: Adequate intake of vitamin K is important for menstruating women working to reduce blood flow. A deficiency could lead to a woman experiencing excess menstrual bleeding. It can also help reduce pain and cramps because it regulates the hormones in the body. Here Are Foods To Eat And Those To Avoid During Your Periods

Cognitive health: Increased levels of vitamin K in the blood have been linked to improved episodic memory in older adults. It limits neuronal damage in the brain thus playing a key role in fighting Alzheimer’s.

Heart health: It appears to keep blood pressure low by preventing mineralization which is where minerals buildup in the arteries. This then enables the heart to pump blood freely through the body. Mineralization naturally occurs with age and is a major risk factor for heart disease. Adequate intake of vitamin K has also been shown to lower the risk of strokeDifferent Types Of Heart Disease And Managing Them

Anti-cancer benefits: A few studies suggest that K2 may help reduce the recurrence of liver cancer and increase survival. A high intake of K2 also lowers the risk of advanced prostate cancer.

Symptoms of vitamin K deficiency

The main symptom is excessive bleeding.

Causes of vitamin K deficiency

People are at an increased risk if they:

  • Take medication with anticoagulants which thin the blood.
  • Are taking antibiotics.
  • Have a condition that causes the body not to absorb fat properly.
  • Have a diet that is extremely lacking in vitamin K.
  • Are an infant. Breast milk is very low in vitamin K. Vitamin K also does not transfer well from mother to baby through the placenta. The liver of a newborn infant does not efficiently use the vitamin and newborns don’t produce K2 on their own for the first few days of life.
