Overview of Vitamins D and K by Life Extension

Getting in your daily requirement of vitamin D from sun exposure or vitamin K from green leafy vegetables is not always easy. These convenient capsules by Life Extension make for an efficient and easy way to get all the great health benefits from vitamins D and K.

What are vitamins, D and K?

Vitamin D3 is a fat-soluble vitamin called cholecalciferol that is essential for the maintenance of healthy bones1, supporting the muscles2 and immune system3 and helping the body absorb calcium4, which in turn helps to support normal muscle function2.

Vitamin K is an essential nutrient that plays a vital role in helping the blood clot5, which affects the way the body bruises and bleeds. It also supports your bones6, making sure you feel strong both in and out of the gym so you can give it your all when training.

What foods contain vitamins, D and K?

The body is capable of making vitamin D, but it requires sunlight exposure to do it; hence vitamin D is often called the sunshine vitamin. Small amounts of vitamin D exists in foods such as fatty fish, egg yolks, and fortified foods, but the majority of people do not get enough from their everyday diet.

Vitamin K is found in primarily in vegetables - especially in green leafy vegetables, vegetable oils, and some fruits.
