Quick Take

Best for covering a poor diet or rare deficiency; outside that, evidence for noticeable benefits is thin.

Vitamin B5, or pantothenic acid, is a water-soluble B vitamin found in meat, eggs, dairy, mushrooms, avocado, legumes, and whole grains. It is converted to coenzyme A, a core compound for fatty-acid metabolism, cellular energy production, and synthesis of steroid hormones and acetylcholine. Its best-supported use is preventing or correcting deficiency. Small human studies also suggest possible benefits for acne and rheumatoid arthritis symptoms. People with very restricted diets, malabsorption, or chronic undernutrition are most likely to benefit.

Potential benefits

Corrects vitamin B5 deficiency

May reduce acne lesions

May improve RA symptoms

May support wound healing

Protocol

Amount

5-10 mg

Frequency

Once daily

When

Any time of day — consistency matters more than timing; take with food if higher doses upset your stomach.

Onset Time

Days to weeks if correcting low intake; little noticeable effect if sufficient

Who Should Consider

Adults with very limited or restrictive diets

People with malabsorption or chronic undernutrition

Heavy alcohol users with poor diet quality

Adults exploring acne support after basics fail

Food Sources

Beef liver (~6-7 mg per 85 g)
Chicken breast (~1 mg per 100 g)
Shiitake mushrooms (~1.5 mg per 100 g)
Avocado (~1.4 mg each)
Sunflower seeds (~2 mg per 30 g)
Yogurt (~1 mg per cup)

How It Works

Pantothenic acid is converted into coenzyme A and acyl carrier protein. These molecules move carbon fragments through fat metabolism, energy production, cholesterol and steroid synthesis, and acetylcholine formation. Low intake can impair tissues with high metabolic demand.
