Vitamin B6: The Brain and Body Booster—A Fun, Detailed Guide for Families
Vitamin B6, also known as pyridoxine, is a water-soluble vitamin that plays a crucial role in keeping both kids and adults healthy and energized. It’s involved in everything from brain development to immune function and even helps the body turn food into the energy you need to play, learn, and grow. Here’s everything you need to know about this essential nutrient, including its health benefits, best sources, how much you need, and what happens if you get too little—or too much.
What Is Vitamin B6?
Vitamin B6 is part of the B-vitamin family. It comes in several forms, but pyridoxine is the most common in supplements and fortified foods. Since it’s water-soluble, your body doesn’t store much, so you need a regular supply from your diet.

Getting too much vitamin B6 from food is nearly impossible. However, high doses from supplements can cause side effects, especially if taken over long periods:
