Niacin
A foundation for cellular energy helpers.
Niacin supplies material for NAD and NADP, coenzymes used in many cellular reactions. They help transfer electrons as the body processes food and builds needed compounds. These biochemical roles do not mean niacin supplements provide an energy boost.
Conceptual illustration, not a molecular structure. Nutrients work together; each has distinct roles.
Make the connection
Connect the nutrient to its role, rather than treating it as a promise of better performance.
Find it in food
Examples, not a complete list. Amounts vary by food and preparation; check labels on fortified foods.
Keep the context
Supplemental nicotinic acid can cause flushing. High doses of niacin can cause serious harm, including liver injury, and require medical supervision.
These pages support learning, not diagnosis or a personalized supplement plan. Symptoms alone cannot identify a nutrient deficiency. A clinician or registered dietitian can help assess individual needs.
Check your recall
What is one role of Niacin?
A foundation for cellular energy helpers.
Does an essential nutrient mean everyone needs a supplement?
No. Essential means the body needs it. Whether a supplement is useful depends on dietary intake, absorption, life stage, health conditions and medicines.
