The Importance of Vitamin B5 (Pantothenic Acid)
Vitamin B5, or pantothenic acid, is a water-soluble vitamin essential for numerous bodily functions. Its name comes from the Greek word pantos, meaning "everywhere," a testament to its wide distribution in both plant and animal foods. Its primary function revolves around energy production, as it is a critical component of Coenzyme A (CoA), which is necessary for metabolizing carbohydrates, fats, and proteins. This metabolic role makes B5 a key player in maintaining your body's energy levels and general cellular health.
Beyond energy, vitamin B5 plays a role in synthesizing hormones and cholesterol, and contributes to healthy skin, hair, and eyes. It is so widely available in foods that a deficiency is extremely rare in developed countries, typically only occurring in cases of severe malnutrition. For most people, simply eating a varied and balanced diet is enough to meet the recommended intake of 5 mg per day.
The Highest Source: Organ Meats
For those seeking the absolute most concentrated source of vitamin B5, organ meats are the answer. Beef liver, specifically, stands out. A single 3-ounce serving can provide over 160% of the recommended daily value, making it a highly efficient way to get this nutrient. While it may not be a dietary staple for everyone, it is a nutritional powerhouse for those who include it in their diet. Other organ meats like kidney are also excellent sources.
Excellent Non-Liver Sources of B5
While organ meats lead the pack, many common and palatable foods provide substantial amounts of vitamin B5. A balanced dietary approach incorporating a mix of these sources ensures you meet your needs without relying on a single food group.
Animal-Based Sources
- Fortified Breakfast Cereals: Many cereals are fortified to contain 100% of the daily value for B5 per serving.
- Fish: Salmon and tuna are great choices. A 3-ounce serving of cooked bluefin tuna provides about 24% of the daily value.
- Poultry: Chicken breast is another reliable source, offering 26% of the daily value in a 3-ounce roasted portion.
- Eggs and Dairy: Eggs, milk, and yogurt all contribute to your daily B5 intake.
Plant-Based Powerhouses
- Mushrooms: Shiitake mushrooms are a standout, with a half-cup cooked serving offering 52% of the daily value. Even white button mushrooms are a good source.
- Sunflower Seeds: Just a quarter-cup of sunflower seeds provides a significant 48% of the daily value.
- Avocados: This creamy fruit is rich in B5, with half an avocado containing about 20% of the daily value.
- Sweet Potatoes and Broccoli: These vegetables are also solid sources, contributing to your intake with each serving.
- Legumes and Whole Grains: Lentils, chickpeas, brown rice, and oats are all dependable sources of pantothenic acid.

What to Know About B5 Intake
While it’s clear that a diverse array of foods offers vitamin B5, a few practical considerations can help you optimize your intake. Since B5 is water-soluble, excess amounts are simply excreted, making toxicity from food sources highly unlikely. However, some research suggests high doses from supplements could potentially cause side effects like diarrhea.
It is also important to note that food processing can lead to a significant loss of pantothenic acid. Choosing fresh, whole, and unprocessed foods over their refined or canned counterparts is generally a better strategy for maximizing your B5 intake. For example, opting for whole grains over refined ones can provide more of this valuable nutrient.
For those on specific diets, such as vegetarian or vegan diets, focusing on plant-based sources like mushrooms, lentils, avocados, and fortified cereals is key to ensuring adequate intake. Given the wide availability, most people can easily meet their requirements without conscious effort.
Conclusion
When considering what food is highest in B5, beef liver is the clear winner, but it's far from the only viable source. With pantothenic acid being so widespread, a balanced diet incorporating a mix of fortified cereals, mushrooms, sunflower seeds, avocados, and various meats and fish will easily meet your needs. By diversifying your food choices, you can effectively support your energy metabolism, hormone synthesis, and overall health without needing to concentrate on a single superfood. A varied and whole-food-focused diet remains the most effective strategy for optimal nutrition.
