In brief: Vitamin B5, or pantothenic acid, is a water-soluble vitamin and a component of coenzyme A. It therefore participates in many metabolic pathways, including fatty-acid metabolism.[1]
How much vitamin B5 is needed?
| Group | Orientation |
|---|---|
| Adults | About 5 mg/day as a common reference |
| Pregnancy | Needs are slightly higher |
| Breastfeeding | Needs are higher than in non-lactating adults |
| Supplements | Extra intake is not automatically necessary |
Food sources
Pantothenic acid is widely distributed in both animal and plant foods, including eggs, meat, fish, dairy, mushrooms, legumes, whole grains and vegetables.
How common is deficiency?
Marked isolated deficiency is rare and usually occurs with severe malnutrition or multiple nutrient deficiencies.
Do people need B5 supplements?
Usually not with a varied diet. Very high supplemental amounts can cause diarrhoea and gastrointestinal discomfort.[1]
Pantothenic acid, pantethine and panthenol
These are not interchangeable terms. Panthenol is commonly used in topical skin and hair products; topical effects do not prove benefit from high-dose oral B5.
FAQ
Does vitamin B5 give more energy?
It is required for normal metabolism, but extra amounts do not reliably increase energy when status is adequate.
Is B5 deficiency common?
No.
Can B5 treat acne?
Small studies exist for specific products, but there is no basis for a general high-dose recommendation.
Does yellow urine indicate B5?
No. Bright yellow urine is more typical after riboflavin (vitamin B2).
Conclusion
Vitamin B5 is essential but widely available in food. High-dose supplementation is usually unnecessary for healthy people with a varied diet.
