Pantothenic acid (vitamin B5) gets its name from the Greek word pantos, meaning "everywhere" — and the name fits. It's present in virtually all plant and animal foods, making true deficiency extraordinarily rare. As a component of coenzyme A (CoA), pantothenic acid is essential for synthesizing and metabolizing fats, carbohydrates, and proteins, producing steroid hormones, and manufacturing the neurotransmitter acetylcholine.
What It Actually Does
Coenzyme A participates in over 100 metabolic reactions, including the citric acid cycle (central to energy production), fatty acid synthesis and oxidation, and the production of steroid hormones (cortisol, sex hormones), hemoglobin, and melatonin. Without adequate B5, your energy production grinds to a halt.
In the skin-care world, B5 (often as dexpanthenol or panthenol in topical products) is valued for its ability to improve skin barrier function, retain moisture, accelerate wound healing, and reduce inflammation. The NIH notes that pantothenic acid contributes to the synthesis of coenzyme A, which is necessary for the synthesis and metabolism of lipids critical for skin barrier integrity.
Why You Should Care
Because B5 is so ubiquitous in food, deficiency is virtually nonexistent outside of severe malnutrition. The adequate intake for adults is just 5 mg daily, a target easily met by eating almost anything. However, B5's role in skin health has made it a popular topical ingredient and oral supplement for acne — with some preliminary evidence (including a small 2014 randomized trial) suggesting high-dose B5 may reduce facial acne lesions, possibly by regulating fatty acid metabolism in sebaceous glands.
The broader takeaway is that B5 works quietly behind the scenes in hundreds of metabolic reactions. You probably don't need to worry about it, but it deserves acknowledgment as a key player in your body's daily biochemistry.
Practical Tips
- Food sources: Found in almost everything — chicken, beef, potatoes, eggs, broccoli, whole grains, avocado, and mushrooms are all good sources.
- Supplements are rarely needed: Unless directed by a provider for a specific purpose, dietary intake is sufficient.
- Topical B5: Dexpanthenol in skin products (5%+ concentration) can help with dry skin, minor burns, and wound healing.
- Acne connection: High-dose B5 (up to 10 g daily) for acne has limited but interesting preliminary data. Consult a dermatologist.
Pantothenic acid is the B vitamin nobody talks about because it rarely causes problems. Sometimes, the best vitamin is the one that just does its job.
