Best Vitamin B5 (Pantothenic Acid) Supplements 2026
Vitamin B5 (pantothenic acid) is an essential water-soluble B vitamin and a precursor to coenzyme A (CoA), which is central to energy metabolism, fatty acid synthesis and oxidation, and steroid hormone production. It is found widely in foods, and deficiency is rare. Supplemental forms are used for acne (dexpanthenol), adrenal support, and energy.
Key benefits
- Coenzyme A synthesis (energy metabolism)
- Adrenal hormone support (adrenal fatigue)
- Acne support (high-dose protocol)
- Wound healing (dexpanthenol form)
- Stress resilience via cortisol pathway
