What Are the Common Types of Vitamins?

Vitamins and other dietary supplements are used by over 75% of the American population. Vitamins carry out several different functions in the body, from helping with metabolic processes in the body to fighting off illnesses.

With so many different types of vitamins, it’s important to know what each one does. In this short guide, we’ll take a look at the main vitamins for health and the benefits of taking them

The Different Types of Vitamins

There are two main types of vitamin:

Fat-soluble vitamins

Water-soluble vitamins

Fat-soluble vitamins are stored in the fatty tissues, where they can be held by the body for a longer period and used gradually. Water-soluble vitamins, on the other hand, are not absorbed as well by the body and need to be taken more regularly.

It’s important to not get confused between vitamins and supplements. A great explanation is that Vitamins are technically supplements, but they are specifically found in foods. Supplements are a broader category for anything that adds nutritional value to your diet or improves your health.
