Why Vitamin B3 is important and its natural sources

Vitamin B3, or niacin, quietly supports energy, brain function, and digestion. It aids DNA repair and nerve cell health. Vitamin B3 may not have the fame of other vitamins, but its role is deep-rooted in metabolism, nerve repair, and aging gracefully. It is not just a side note in a nutrition chart—it’s an anchor that holds multiple systems together.
