A closer look
What forms will I see on a label?
Calcium pantothenate is a common supplement form. Pantethine is a related ingredient rather than the same label term.
Why people use it
People obtain B5 in multivitamins and B-complex formulas to support normal nutrient metabolism and meet daily needs.
These are common goals and marketing uses. The evidence section below explains what research supports.
What does the evidence tell us?
B5 is widespread in foods, and deficiency is uncommon. General metabolism claims do not demonstrate benefits from extra B5 when intake is adequate.
What should I know before using it?
Very large supplemental amounts may cause diarrhoea or digestive discomfort.
