Top 10 products ranked

Last reviewed May 2026

Clinical dose: 50–500 mg

Why Vitamin B5 for Energy

Vitamin B5 plays a supporting role in energy. Essential precursor to coenzyme A (CoA), which is required for energy production and for synthesizing and metabolizing fats, proteins, and carbohydrates. Also supports adrenal hormone production and stress response. In clinical studies, vitamin b5 powers energy production.

What dose to look for

Clinical studies typically use 50–500 mg of vitamin b5. Standard B-complex supplement range. Products below this range may not deliver meaningful results.

What the research says

Vitamin B5 has strong clinical evidence for energy benefits. Essential coenzyme A precursor; deficiency is virtually unknown due to presence in nearly all foods Learn more

Clinical research on Pantothenic Acid (Vitamin B5)

LOW — Theoretical energy role via CoA synthesis, virtually no clinical data · 5 mg/day (AI); no established therapeutic dose for energy

•Pantothenic acid is the precursor for coenzyme A (CoA) — required for fatty acid oxidation, the TCA cycle, and acetylcholine synthesis. Theoretically critical for energy metabolism.
•Deficiency is extremely rare ('pantothenic' comes from Greek 'pantos' meaning 'everywhere' — it's in almost all foods). There are zero RCTs testing pantothenic acid supplementation for energy or fatigue outcomes.
