Calcium Pantothenate

Calcium Pantothenate (calcium salt of pantothenic acid)

Calcium pantothenate is the calcium salt most commonly used to supply vitamin B5; for a useful product comparison, compare pantothenic acid per serving and account for duplicate B5 in multivitamins or B-complexes.

It dissociates to provide pantothenate for coenzyme A synthesis.

Potential effects and evidence map

Evidence is strong for the essential nutrient role of pantothenic acid, but supplementation beyond adequacy has not been shown to produce a reliable general nootropic effect in well-nourished adults. Form-specific clinical uses should be evaluated separately.

B
Dose- and form-specific safety1

Ordinary nutritional use has minimal known risk; extremely high pantothenic-acid intakes can cause diarrhea and stomach upset.

FAQ

What distinguishes Calcium Pantothenate from related forms?

1

The label should report pantothenic-acid equivalence; calcium pantothenate is not the same ingredient or evidence base as pantethine.
