The nutrient, in context

How to read this ranking

This page compares Niacin (Niacin), in mg per 100 g of food.

Chemical forms and measurement methods remain separate. “Not reported” means a value is unavailable, not that the food contains zero. A food’s rank does not determine your individual needs or diagnose a deficiency.

Intake guidance

There is no validated NIH ODS fact sheet for this identity in Bitameans’ published version. We do not assign another nutrient’s recommendations to this form. An absent fact sheet does not mean that no upper intake limit exists.
