Vitamin K

Vitamin K is a group of fat-soluble vitamins also known as phylloquinones. They play an important role in blood clotting and bone health.

There are two main types of vitamin K:

1. K1 (phylloquinone): Found in leafy green vegetables such as spinach, kale, lettuce. Also found in vegetable oils.

2. K2 (menaquinones): produced by bacteria in the intestines. Also found in fermented foods such as cheese and sauerkraut.

Vitamin K is necessary for the synthesis of proteins involved in blood clotting. It helps prevent excess bleeding.

In addition, vitamin K is involved in bone metabolism, maintaining bone health and preventing osteoporosis.

A lack of vitamin K can lead to increased bleeding and weakened bones. Adequate intake of vitamin K is important for maintaining health. The recommended daily intake is 90-120 mcg.
