B6 is a hard-working multitasker that affects your mood, appetite, sleep, and thinking. In addition to helping you fight off infections, it helps turn food into energy and helps blood carry oxygen throughout your body. It also breaks down protein, carbohydrates, and fats.

Protein sources such as poultry, beef, and fish are some of the most common ways to get B6. Learn more about the benefits of B6.
