Calcium pantothenate is a stable salt form of pantothenic acid, or vitamin B5, a nutrient involved in making coenzyme A, which the body uses to metabolize fats, carbohydrates, and proteins.
Why it’s used
Taken as a source of vitamin B5, generally as part of a broader multivitamin intake rather than for a specific standalone effect.
What the evidence is for
supporting normal energy metabolism via coenzyme A synthesis.
What the evidence says
NIH ODS confirms pantothenic acid's established role in energy metabolism and notes that deficiency is rare because the nutrient is widespread in food. Evidence for benefits from supplementing beyond typical dietary intake, such as for skin or athletic claims sometimes made for B5, is limited.
Context
NIH ODS sets an adequate intake of about 5 mg/day for adults rather than an RDA, and has not established a tolerable upper intake level, so there is no defined upper end to a studied range.
Rumors

No upper limit has been set — the data was not sufficient to set one, which is a gap in the research rather than a finding about safety.
