All You Need To Know About Fat-soluble Vitamins

As the name suggests, fat-soluble vitamins are a type of vitamin that is absorbed into the body through fatty tissue.

The human body requires a variety of vitamins to keep working properly. There are two types of vitamins: water-soluble and fat-soluble vitamins.


Vitamins are often obtained through regular food intake. Some people require or want additional vitamins provided through supplements.

Though both types of vitamin are important to the body, this article focuses on the types, functions, and sources of fat-soluble vitamins.

What are fat-soluble vitamins?

Fat-soluble vitamins will not dissolve in water. Instead, fat-soluble vitamins absorb best when taken with higher-fat foods.

Once absorbed into the body, fat-soluble vitamins are stored in fatty tissues and liver. The body can use these stores for future use. The water-soluble vitamins are vitamins B and C.

There are four types of fat-soluble vitamins:

vitamin A

vitamin D

vitamin E

vitamin K

Each type of fat-soluble vitamin promotes different functions in the body. People deficient in the fat-soluble vitamins may require supplements to boost their supply.

However, it is possible to take in too much of a fat-soluble vitamin, which could lead to toxicity and adverse reactions.
