Why Is Vitamin B5 Called the Universal Vitamin?
Pantothenic acid, or vitamin B5, gets its name from the Greek word "pantos," meaning "everywhere." This is an apt name because pantothenic acid is found in almost every food — meat, eggs, grains, vegetables, and nuts. Paradoxically, it is also one of the lesser-known B-vitamins.
Pantothenic acid is an essential component of coenzyme A (CoA) (EFSA, 2009). CoA participates in more than 100 metabolic reactions, including:
- Fat synthesis and breakdown — fatty acid oxidation and lipogenesis
- Energy production — a central component of the citric acid cycle (Krebs cycle)
- Hormone synthesis — steroid hormones, adrenal hormones
- Neurotransmitter production — acetylcholine synthesis
- Hemoglobin synthesis — red blood cell production
Without adequate pantothenic acid, the body cannot efficiently produce energy or metabolize fats.
Does Vitamin B5 Really Help With Acne?
One of the most popular claims about pantothenic acid is its ability to help with acne. This idea originates from Dr. Lit-Hung Leung's 1995 hypothesis.
Leung's Theory
Dr. Leung proposed that acne develops partly due to coenzyme A deficiency. His logic:
1. The body needs CoA for both energy production and fat metabolism
2. When CoA is scarce, the body prioritizes energy production over fat metabolism
3. This causes sebaceous gland hyperactivity — excess sebum accumulates in skin pores
4. High-dose pantothenic acid increases CoA levels and normalizes sebum production
What Do Studies Show?
Yang et al. (2014) — randomized, double-blind, placebo-controlled study:
- 41 participants with mild to moderate acne
- Dexpanthenol (pantothenic acid derivative) 2.2 g daily for 12 weeks
- Result: 68.7% reduction in inflammatory lesions vs 44.8% in placebo group
- Sebum production decreased significantly
Capodice (2012) — open-label study:
- Pantothenic acid-based supplement 2.2 g daily
- Significant reduction in lesion count at 8 weeks
Summary on acne:
- Evidence is promising but preliminary — more large studies are needed
- Doses are very high — 2,000–10,000 mg per day, far above the standard dose
- Effects are slow — expect to wait at least 8–12 weeks for results
- Better alternative: nicotinamide (B3) has stronger evidence for acne
What Role Does Vitamin B5 Play in Energy Production?
Pantothenic acid is a central link in energy metabolism. Without it, the citric acid cycle cannot function, and the body cannot efficiently convert food into energy.
How Pantothenic Acid Produces Energy
Coenzyme A and energy production:
1. Carbohydrate breakdown — pyruvate is converted to acetyl-CoA (requires pantothenic acid)
2. Fat oxidation — fatty acids are converted to acetyl-CoA (requires pantothenic acid)
3. Citric acid cycle — acetyl-CoA enters the cycle and produces NADH and FADH2
4. Electron transport chain — NADH and FADH2 produce ATP, which is energy
Practically every calorie you consume must pass through a CoA-dependent pathway to become usable energy.
Why Do You Feel Tired — Could It Be B5 Deficiency?
Fortunately, pantothenic acid deficiency is extremely rare since it is found in so many foods. However, certain situations can increase the need:
- Intense training — increases CoA demand for energy production
- Chronic stress — adrenal hormone production consumes CoA
- Alcohol consumption — interferes with pantothenic acid absorption
- Restricted diets — very low-calorie diets
Symptoms that may indicate deficiency:
- Fatigue and lack of energy
- Sleep disturbances
- Burning and numbness in feet ("burning feet syndrome")
- Digestive issues
- Irritability and mood changes
Does Pantothenic Acid Help With Stress?
Pantothenic acid is often called the "anti-stress vitamin," and there is a biological basis for this.
Adrenal Glands and Pantothenic Acid
The adrenal glands are the body's stress response center and among the largest consumers of pantothenic acid:
- Cortisol synthesis requires CoA — cortisol is the primary stress hormone
- Aldosterone synthesis requires CoA — regulates water and salt balance
- DHEA synthesis requires CoA — the "youth hormone"
During chronic stress, the adrenals consume more CoA, potentially creating a greater need for pantothenic acid.
Scientific Evidence
- Tahiliani & Beinlich (1991) showed that pantothenic acid deficiency reduced adrenal hormone production in animal models
- Human studies are limited, but anecdotal evidence suggests benefits for stress and fatigue
- Pantothenic acid + vitamin C + magnesium combination is often recommended for adrenal support
What Are the Best Sources and Forms of Pantothenic Acid?
Food Sources
| Food | B5 (mg/100g) |
|---|---|
| Chicken liver | 8.3 |
| Sunflower seeds | 7.1 |
| Salmon | 1.9 |
| Avocado | 1.5 |
| Eggs (one) | 0.7 |
| Sweet potato | 0.7 |
| Mushrooms | 1.5 |
| Lentils | 1.4 |
Supplement Forms
Calcium D-pantothenate — the most common and affordable form. Well absorbed and stable.
Dexpanthenol (panthenol) — a form used in skincare that converts to pantothenic acid in the body. Also available orally.
Pantethine — a dimethyl pantothenic acid derivative with better absorption. Some studies show improved bioavailability.
Recommended doses:
- General health: 5–10 mg daily (recommended daily intake)
- Athletes: 10–50 mg daily
- Acne: 2,000–5,000 mg daily (under medical supervision only)
- Stress support: 100–500 mg daily
Summary: Who Should Use Vitamin B5 and How?
Pantothenic acid is a universal vitamin whose needs are usually met by a varied diet. However, supplementation can be beneficial in certain situations:
For acne:

How Does Pantothenic Acid Affect Hair and Nails?
Pantothenic acid is a common ingredient in hair care products and nail strengtheners, and there is a biological basis for this.
Pantothenic Acid and Hair Growth
- Pantothenic acid supports hair follicle metabolism and energy production
- Deficiency can cause hair loss and graying (in animal studies)
- Dexpanthenol (panthenol) in shampoos and conditioners is a pantothenic acid derivative
- It moisturizes and strengthens the hair shaft, making hair stronger
- Human studies are limited, but anecdotal evidence is positive
Pantothenic Acid and Nails
- Vitamin B5 supports keratin synthesis — keratin is the primary nail protein
- Brittle, easily breaking nails may indicate B-vitamin deficiency
- Combination with biotin gives better results for nail strengthening
Pantothenic Acid and Wound Healing
Pantothenic acid plays an important role in wound repair:
- Vickers et al. (2007) found that dexpanthenol accelerated wound healing in animal models
- Panthenol is widely used in wound care — in creams and ointments
- Oral pantothenic acid (500–1,000 mg) may support wound healing post-surgery
- Pantothenic acid supports collagen synthesis — important for skin repair
- Combine with vitamin C and zinc for the best wound healing effect
Pantothenic Acid and the Digestive Tract
Vitamin B5 supports digestive health in several ways:
- Intestinal motility — pantothenic acid supports smooth muscle function
- Deficiency can cause constipation and digestive disturbances
- Some practitioners use high doses (1,000+ mg) to relieve constipation
- Pantothenic acid also supports intestinal mucosa health and repair

Frequently Asked Questions About Vitamin B5
Does pantothenic acid really help with acne?
Evidence is promising but doses are very high (2,000–5,000 mg daily). Nicotinamide (B3) is a better-proven alternative for acne. Try both and see which works for you.
Can I take too much pantothenic acid?
Pantothenic acid is water-soluble and excess is excreted in urine. No toxicity has been observed even at high doses. However, digestive issues may occur above 10,000 mg.
Does B5 help with stress?
Pantothenic acid is called the anti-stress vitamin because adrenal glands need it for cortisol production. However, scientific evidence is mainly from animal studies.
What is the best way to get pantothenic acid?
A varied diet usually provides enough. For supplements, calcium D-pantothenate is the most common and well-studied form. A B-vitamin complex conveniently covers all B-vitamins.
