Pantothenic acid is a water-soluble B vitamin required to make coenzyme A, a molecule central to energy metabolism in every cell.
Why it’s used
Taken to support normal energy metabolism, as part of general multivitamin or B-complex formulations.
What the evidence is for
supporting normal energy metabolism via coenzyme A synthesis.
What the evidence says
Per NIH ODS, its role in coenzyme A synthesis and metabolism is well established, and deficiency is rare because it is widespread in food. Evidence that supplementation above typical intake provides additional benefit in well-nourished people is limited.
Dose studied
5–5 mg — Adequate Intake for adults, per NIH ODS.
Context
NIH ODS sets an Adequate Intake based on typical dietary consumption rather than a formal RDA.
