Pantothenic Acid (Vitamin B5): The Underrated Energy Orchestrator
Pantothenic acid — vitamin B5 — rarely gets top billing in the supplement world. Yet it is the direct precursor to coenzyme A (CoA), one of the most metabolically central molecules in human biochemistry. Every cell in your body depends on CoA for energy production, fat metabolism, and hormone synthesis.
Coenzyme A: Pantothenic Acid's Legacy
Coenzyme A participates in over 100 metabolic reactions. Its core roles include:
- Acetyl-CoA formation — the product of glycolysis, gateway to the citric acid cycle
- Fatty acid synthesis and beta-oxidation — essential for both making and burning fat
- Cholesterol and steroid hormone synthesis — cortisol, testosterone, oestrogen all require CoA
- Haemoglobin synthesis — supporting red blood cell production
- Acetylcholine formation — for this critical neurotransmitter (Kelly, 2011)
Pantothenic Acid and Acne: The Unexpected Connection
One of the most surprising applications of B5 is acne management. The hypothesis: pantothenic acid is rate-limiting for sebaceous gland fatty acid metabolism; deficiency leads to sebum accumulation and acne formation (Leung, 1995).
A randomised controlled trial (Leung, 2014) demonstrated statistically significant reductions in acne lesion count with a daily dose of approximately 2.2 g of pantothenic acid — with a favourable safety profile compared to pharmaceutical retinoids.
BIOTECHUSA B-Complex 60tab provides a daily maintenance dose of B5 within a comprehensive B formula.

Pantothenic Acid, Adrenals, and Stress Resilience
The adrenal glands use CoA to synthesise cortisol and other stress hormones. During periods of chronic stress, pantothenic acid turnover increases. Some researchers argue that insufficient B5 can impair adrenal function and reduce stress resilience (Kelly, 2011).
For athletes in heavy training blocks — a physiological stressor that activates the hypothalamic-pituitary-adrenal (HPA) axis — maintaining optimal B5 status may support the hormonal response to training.
Athletic Performance and Pantothenic Acid
Fat oxidation during prolonged exercise depends critically on CoA availability. Some researchers propose that optimising CoA status may enhance endurance performance by improving fatty acid mobilisation. While direct performance studies are limited (Wall et al., 2012), the mechanistic basis is sound.
Supplement Forms
| Form | Bioavailability | Notes |
|---|---|---|
| Calcium pantothenate | Good | Most common supplement form |
| Pantethine | Very good | Fat-soluble derivative, higher bioavailability |
| Dexpanthenol | Good | Topical use — skin and hair |
Who Is at Risk of Deficiency?
Pantothenic acid is found in virtually all foods (the name comes from the Greek 'pantothen', meaning 'from everywhere'). Isolated deficiency is extremely rare — occurring primarily in synthetic diet research subjects, severe alcoholics, and those with significant malabsorption.
Symptoms of deficiency include: fatigue, burning feet syndrome, tingling extremities, dizziness, and irritability.
Dosing Recommendations
EFSA adequate intake: 5 mg/day for adults. Supplements typically provide 50–500 mg. The acne protocol doses (up to 10 g/day) are significantly higher and require monitoring. No tolerable upper level has been set, as B5 has a very wide safety margin (EFSA, 2016).
Best Food Sources
- Beef and chicken liver (excellent)
- Meat and poultry generally
- Shiitake mushrooms
- Sunflower seeds
- Avocado
- Legumes and lentils

FAQ
Does B5 work for acne?
There is moderate clinical evidence supporting 2–10 g/day for reducing acne lesion count. Larger doses show more promising results but are expensive and harder to tolerate. It is not a first-line treatment for severe acne but may be a useful adjunct.
Does B5 help with stress?
Pantothenic acid supports adrenal function, which is integral to the stress response. It is not a direct anxiolytic, but deficiency may impair stress resilience. Maintaining optimal B5 status helps the body respond normally to stressors.
When is the best time to take a B5 supplement?
B5 absorbs well with or without food. For high doses, split throughout the day to maximise absorption. Always combine with other B vitamins for balanced support.
