What is Vitamin B5 and Why Do We Need It?
Vitamin B5, also known as pantothenic acid, is a water-soluble vitamin essential for life. It plays a central role in converting food into usable energy by synthesizing coenzyme A (CoA), a critical molecule for metabolizing fats, proteins, and carbohydrates. Beyond energy, it is involved in synthesizing sex and stress-related hormones, forming red blood cells, and maintaining healthy skin and hair. Since the body doesn't store water-soluble vitamins, a consistent intake through diet is necessary.
The Top Food Source: Chicken Liver
Based on nutritional data, cooked chicken liver stands out as one of the most potent sources of vitamin B5. A 3.5-ounce serving provides a substantial amount of the recommended daily value, making it a nutritional powerhouse. For those who consume organ meats, incorporating chicken or beef liver into their diet is an effective way to maximize pantothenic acid intake.
Other Significant Sources of Pantothenic Acid
While organ meats may lead the pack, several other foods are also excellent sources of vitamin B5, catering to various dietary preferences.
Animal Sources:
- Salmon and Tuna: Wild-caught salmon and tuna are good sources of B5.
- Eggs: A single large, hard-boiled egg offers a decent amount.
- Dairy Products: Milk and yogurt are good contributors.
- Beef and Poultry: Lean chicken breast and beef also provide B5.
Plant-Based Sources:
- Shiitake Mushrooms: Cooked shiitake mushrooms are an excellent plant-based source.
- Sunflower Seeds: These are packed with B5.
- Avocado: A fantastic source of B vitamins, including B5.
- Legumes: Lentils, split peas, and chickpeas are good options for a B5 boost.
- Whole Grains: Whole-wheat and brown rice contain pantothenic acid.
The Impact of Food Processing on Vitamin B5 Content
Pantothenic acid is susceptible to significant loss during food processing. Milling grains can reduce B5 content by up to 75%. Freezing and canning can also diminish its potency. To retain maximum nutrients, opt for fresh, unprocessed foods whenever possible.
Comparison of High Vitamin B5 Food Sources
The following table compares the vitamin B5 content of some of the richest sources. Daily Value (DV) percentages are based on the standard 5 mg Adequate Intake (AI) for adults.
| Food Source | Portion | Pantothenic Acid Content | Percentage of Daily Value (DV) | Other Key Nutrients |
|---|---|---|---|---|
| Chicken Liver (cooked) | 3.5 ounces (100g) | 6.2 mg | 125% | High in B12, Iron, Folate |
| Dried Shiitake Mushrooms | 10 mushrooms (36g) | 7.8 mg | 156% | High in Copper, Selenium |
| Sunflower Seeds (dry-roasted) | 1/4 cup | 2.4 mg | 48% | High in Protein, Vitamin E |
| Avocado (raw) | 1/2 fruit | 1.0 mg | 20% | High in healthy fats, Potassium |
| Trout (cooked) | 3 ounces | 1.9 mg | 38% | High in Protein, Omega-3s |
| Lentils (cooked) | 1 cup | 1.3 mg | 25% | High in Folate, Manganese, Protein |
How Vitamin B5 Supports Overall Health
Beyond its role in energy production, a diet rich in vitamin B5 provides numerous health benefits:
- Energy and Fatigue Reduction: B5 helps combat fatigue and weakness by aiding energy metabolism.
- Skin and Hair Health: Pantothenic acid contributes to healthy skin by moisturizing and promoting wound healing.
- Stress Management: It plays a role in the function of the adrenal glands, which produce stress hormones.
- Heart Health: Some research suggests pantethine may help lower cholesterol and triglyceride levels.
- Immune System Function: It supports a healthy immune system by aiding in antibody production.
Conclusion
To answer the question of which food is highest in vitamin B5?, organ meats, particularly liver, are the top sources. However, because the vitamin is widespread, a balanced diet with a variety of foods—including shiitake mushrooms, sunflower seeds, and avocado—is usually sufficient. Since B5 is lost during processing, choosing fresh, whole foods is best. Incorporating these foods supports energy production, stress response, and overall vitality.

Incorporating Vitamin B5 Rich Foods into Your Diet
Adding these foods to your meals can be simple:
- Add Cooked Liver to Dishes: Use small amounts of sautéed chicken or beef liver in pasta sauces or on toast.
- Snack on Sunflower Seeds: Toss toasted sunflower seeds into salads or enjoy them as a snack.
- Use Avocado in Every Meal: Add avocado to sandwiches, tacos, or salads, or mash it on toast.
- Cook with Shiitake Mushrooms: Sauté shiitake mushrooms and add them to stir-fries, soups, or omelets.
- Eat More Legumes: Incorporate lentils, split peas, or chickpeas into soups, stews, and side dishes.
- Choose Whole Grains: Opt for brown rice over white rice to retain more nutrients.
Potential Issues and Considerations
While deficiency is rare with a balanced diet, certain factors increase risk, such as conditions affecting nutrient absorption, excessive alcohol, or genetic disorders. Symptoms are typically nonspecific, including fatigue and irritability. High-dose supplements can cause mild digestive issues, but toxicity from food is not a concern. Consult a healthcare professional before taking high-dose supplements.

What are the main dietary sources of Vitamin B5?
Pantothenic acid is widespread, with key sources including organ meats (liver, kidney), fish (salmon, tuna), dairy (milk, yogurt), eggs, vegetables (mushrooms, avocados, broccoli), legumes, and whole grains.
Why is Vitamin B5 important for health?
Vitamin B5 is crucial for converting food into energy, synthesizing coenzyme A, creating red blood cells, and forming sex and stress-related hormones. It also helps maintain healthy skin and hair.
Is Vitamin B5 lost during food preparation?
Yes, because vitamin B5 is water-soluble, it can leach into cooking liquids. Food processing like milling can also significantly reduce its content. Opting for fresh, whole foods is the best way to preserve the vitamin.
Can you get too much vitamin B5 from food?
No, it is very difficult to consume a toxic amount of vitamin B5 from food sources alone. Excess amounts are simply excreted in the urine.
Who is at risk for a vitamin B5 deficiency?
Vitamin B5 deficiency is extremely rare. It primarily occurs in individuals with severe malnutrition, alcoholism, certain genetic disorders like PKAN, or conditions affecting nutrient absorption.
Does vitamin B5 help with acne?
Some research suggests that topical and dietary forms of vitamin B5 (specifically dexpanthenol) may help reduce facial blemishes and promote skin health, but more studies are needed to confirm these effects.
How does vitamin B5 support skin health?
Vitamin B5 in the form of dexpanthenol acts as a moisturizer for the skin and enhances the healing process of wounds, relieving irritation from conditions like eczema and insect bites.
