Niacin-Rich Foods That Support Energy and Focus

12. Why B3 Matters

Niacin isn’t flashy, but it’s essential. It helps your body turn food into energy, supports brain and nerve health, and plays a quiet but constant role in keeping your metabolism steady.

Because the body doesn’t store much of it, your daily intake matters more than you might think. Even mild shortfalls can leave you feeling foggy, sluggish, or off balance.

A varied diet with plenty of protein from meat, fish, legumes, or fortified foods can cover your needs without relying on supplements. For everyday energy and focus, food usually does the job.
