Vitamin B5, also known as pantothenic acid, is one of the essential B-complex vitamins that plays a critical role in energy production, hormone synthesis, and overall cellular function. Although it is found in a wide variety of foods and deficiency is rare, Vitamin B5 is vital for maintaining optimal health.
In this guide, you will learn everything about Vitamin B5, including its benefits, recommended dosage, deficiency symptoms, side effects, food sources, and who should or should not take supplements.
What is Vitamin B5?
Vitamin B5, scientifically known as pantothenic acid, is a water-soluble vitamin belonging to the B-complex family. The name “pantothenic” comes from the Greek word “pantothen,” meaning “from everywhere,” because this vitamin is present in almost all plant and animal foods.
Vitamin B5 is essential for the production of coenzyme A (CoA), a compound that helps convert carbohydrates, fats, and proteins into usable energy. It is also involved in synthesizing cholesterol, steroid hormones, neurotransmitters, and hemoglobin.
Since Vitamin B5 is water-soluble, the body does not store it in large amounts. Therefore, regular dietary intake is necessary to maintain healthy levels.
Vitamin B5 Dosage
Below is the recommended daily intake (Adequate Intake – AI) for Pantothenic acid according to age and life stage. Currently, there is no officially established Tolerable Upper Intake Level (UL) due to its low toxicity, but very high doses may cause side effects.
Recommended Daily Intake of Vitamin B5
| Age Group | Recommended Intake (mg/day) |
|---|---|
| 0–6 months | 1.7 mg |
| 7–12 months | 1.8 mg |
| 1–3 years | 2 mg |
| 4–8 years | 3 mg |
| 9–13 years | 4 mg |
| 14 years and above | 5 mg |
| Pregnant women | 6 mg |
| Breastfeeding women | 7 mg |
Note: There is no established Upper Intake Limit (UL), but doses above 1,000 mg per day may increase the risk of digestive discomfort.
