Niacin-Rich Foods That Support Energy and Focus

1. Where to Find Niacin in Food

Niacin is found in both animal- and plant-based foods, especially those rich in protein. Poultry, fish, legumes, seeds, and whole grains are all solid sources.

Your body also has a backup plan. It can make niacin from tryptophan, an amino acid found in many high-protein foods. That gives you two ways to meet your needs: direct intake from food and internal conversion.

Cooking and processing can lower niacin content slightly, but most whole foods still provide useful amounts. And because excess niacin from food is filtered out in urine, there’s little risk of getting too much from meals alone.
