How Vitamins Work Within the Body

We discuss vitamins frequently on social media and in our blogs, but you might also be wondering just how these vitamins work within the body. There are 13 essential vitamins but to keep it simple the main ones are A, C, D, E, K, and B. B vitamins come in 8 different varieties: biotin, folic acid, niacin, pantothenic acid, riboflavin, thiamin, vitamin B6, and Vitamin B12. Vitamins are essential to our health because they perform vital functions in the body.

The Two Types of Vitamins

The two types of vitamins are water-soluble and fat-soluble according to HelpGuide.


The water-soluble vitamins include all of the B vitamins as well as vitamin C. These vitamins with many things including energy and tissue health. They help get energy from the food we eat, create energy, build proteins and help cells multiply. Vitamin C also helps make collagen which helps repair cuts and scrapes and supports healthy bones. According to MedlinePlus, the body does not store water-soluble vitamins and leftovers leave the body through urine. Therefore, we must consume them regularly.


The fat-soluble vitamins include A, D, E, and K. These vitamins support the vision and bone formation. They also help maintain a healthy nervous system and support gut, skin, and lung health. According to MedlinePlus, fat-soluble vitamins are stored in the body’s liver, fatty tissue, and muscles.
