Pantothenic Acid
Also known as: Vitamin B5, Pantothenate, Calcium pantothenate, d-Pantothenic acid
Effective Dosage
No established therapeutic dose from provided studies
What the Science Says
Pantothenic acid is vitamin B5, a water-soluble nutrient found in nearly all foods. It is a required building block for coenzyme A (CoA), a molecule central to energy metabolism, fatty acid processing, and cellular repair. Research suggests that low pantothenic acid levels may be associated with neurodegeneration, and animal studies show it can reduce inflammation and support tissue barrier integrity, though most of these findings have not yet been confirmed in large human trials.
What It Doesn't Do
Won't boost exercise performance or increase muscle coenzyme A levels — a clinical trial found no effect even at high doses. No proven benefit for healthy adults who already get enough from food. Not a treatment for Parkinson's disease, despite observational links. No strong evidence it improves skin, hair, or wound healing in people who aren't deficient.
Evidence-Based Benefits
Pantothenic acid is essential for the synthesis of coenzyme A, which plays a crucial role in fatty acid metabolism and energy production. It is also involved in the synthesis of hormones and cholesterol, contributing to overall metabolic health.

Absorption & Bioavailability
Good — pantothenic acid is readily absorbed from food and supplements; excess is excreted in urine, so toxicity is not a concern at typical doses
Red Flags to Watch For
- High-dose supplements (1.5 g/day or more) showed no measurable benefit in a controlled exercise trial, suggesting most people don't need supplementation
- Often included in multi-ingredient products (hydration drinks, B-complex formulas) making it impossible to isolate its specific effects
- Deficiency is extremely rare in people eating a normal diet — marketing claims about widespread deficiency are not supported by the evidence
- Most exciting findings (Parkinson's disease, endometrial protection) come from observational or animal studies, not human clinical trials
