Pantothenic Acid for Athletes: Vitamin B5 for Energy and Stress Response
Published: Nutrition & Performance Guide
Ever wonder why you feel drained during intense training blocks despite eating enough calories? You might be overlooking pantothenic acid (vitamin B5)—the essential B-vitamin that powers every single energy-producing pathway in your body. As the precursor to coenzyme A, pantothenic acid is critical for converting food into ATP, synthesizing stress hormones like cortisol, and metabolizing fat during exercise. Here's why athletes need to optimize their B5 intake for peak performance and recovery.
Understanding Pantothenic Acid
Pantothenic acid, also known as vitamin B5, is a water-soluble B-vitamin essential for synthesizing and metabolizing fats, carbohydrates, and proteins. The name "pantothenic" comes from the Greek word "pantos," meaning "everywhere," reflecting the fact that this vitamin is found in virtually all foods. For athletes, pantothenic acid is critical because it's the precursor to coenzyme A (CoA), one of the most important molecules in cellular energy production and metabolism.
Think of pantothenic acid as the metabolic facilitator—it doesn't just help you extract energy from food, it's also essential for synthesizing fatty acids, cholesterol, steroid hormones (including testosterone and cortisol), neurotransmitters, and even hemoglobin. Without adequate B5, your energy systems, hormone production, and recovery capacity all suffer.
Why Pantothenic Acid Matters for Athletes
Research from Harvard Medical School and the National Institutes of Health has established pantothenic acid as essential for optimal athletic performance. Here's why B5 is non-negotiable for serious athletes:
⚡ Quick Facts for Athletes
- ✓ Universal Energy Cofactor: Required for the Krebs cycle—the primary ATP-generating pathway
- ✓ Stress Response: Essential for cortisol production during intense training and recovery
- ✓ Fat Metabolism: Critical for synthesizing and breaking down fatty acids during aerobic exercise
- ✓ Hormone Production: Supports testosterone, estrogen, and other steroid hormone synthesis
- ✓ Widely Available: Found in nearly all whole foods, deficiency is rare with varied diet
Impact on Training Performance
- Strength training: Supports testosterone synthesis and protein metabolism for muscle growth and recovery
- Endurance training: Essential for fat oxidation during prolonged aerobic exercise—up to 70% of energy from fat oxidation
- Recovery: Produces cortisol and other stress hormones that regulate inflammation and tissue repair
- Energy production: CoA is required for every single metabolic pathway that generates ATP from food
📊 What Research Shows
Studies from the American College of Sports Medicine: Athletes under physical and psychological stress have significantly increased pantothenic acid requirements. Research shows that B5 depletion impairs energy production, reduces stress hormone synthesis, and increases fatigue markers during intense training periods.
Practical takeaway: Meeting elevated B5 needs (7-10 mg/day for athletes vs. 5 mg for sedentary individuals) supports optimal energy metabolism, stress response, and recovery capacity.
Key Functions and Benefits
Primary Functions:
- Coenzyme A synthesis: Precursor to CoA, essential for energy production from all three macronutrients
- Fatty acid metabolism: Required for synthesizing and breaking down fats
- Krebs cycle (citric acid cycle): CoA is the entry point for energy extraction from carbs, fats, and proteins
- Steroid hormone synthesis: Produces cortisol, testosterone, estrogen, and other hormones
- Neurotransmitter production: Synthesizes acetylcholine for nerve and muscle function
- Hemoglobin synthesis: Supports red blood cell production and oxygen transport
- Cholesterol synthesis: Essential for cell membrane production and hormone precursors
The "Anti-Stress" Vitamin
Pantothenic acid is often called the "anti-stress vitamin" because it's essential for producing cortisol and other adrenal hormones that help your body cope with physical and mental stress. Intense training, sleep deprivation, and life stress all increase pantothenic acid requirements. According to Mayo Clinic researchers, inadequate B5 can impair stress response, hormone balance, and recovery capacity.
Recommended Intake
Adequate Intake (AI):
Note: No RDA has been established; instead, an Adequate Intake (AI) is used:
- Men and Women (14+ years): 5 mg per day
- Pregnant women: 6 mg per day
- Breastfeeding women: 7 mg per day
Athletes and Active Individuals:
- Moderate activity: 5-7 mg per day (meet AI)
- High-intensity training: 7-10 mg per day (increased energy demands)
- Periods of high stress: Up to 10-15 mg per day may be beneficial
- No established upper limit: Excess B5 is excreted in urine (water-soluble)

Truly "Everywhere"
Pantothenic acid lives up to its name—it's found in virtually all whole foods. As long as you're eating a varied diet with adequate protein, vegetables, and whole grains, deficiency is extremely rare. However, highly processed diets low in whole foods can lead to suboptimal intake, particularly during periods of high physical or psychological stress.
Pantothenic Acid for Different Training Goals
High-Intensity and Endurance Training
- Pantothenic acid needs: 7-10 mg per day
- Why: Increased energy turnover and stress hormone production
- Best sources: Organ meats, fortified cereals, avocado, sunflower seeds, mushrooms
- Strategy: Include B5-rich foods at every meal for sustained energy
Fat Loss/Cutting
- Pantothenic acid needs: 5-7 mg per day
- Why: Essential for fat oxidation and energy from stored body fat
- Best sources: Low-calorie, high-B5 foods like mushrooms, broccoli, chicken breast
- Strategy: Ensure adequate B5 to optimize fat metabolism during deficit
High-Stress Periods
- Pantothenic acid needs: 7-15 mg per day
- Why: Supports cortisol production for stress response and recovery
- Best sources: Organ meats, fortified cereals, eggs, yogurt, avocado
- Strategy: Increase B5 intake during competition prep, heavy training blocks, or life stress
Deficiency and Excess
Pantothenic Acid Deficiency
Deficiency is extremely rare due to widespread availability in foods, but has been induced experimentally and observed in severe malnutrition. The National Institutes of Health notes that athletes on highly restrictive or processed diets may risk suboptimal intake:
Deficiency Symptoms (rare):
- Fatigue and weakness: Impaired energy production
- Burning feet syndrome: Painful, burning sensation in the feet (paresthesia)
- Insomnia and irritability: Neurological symptoms
- Numbness and muscle cramps
- Headaches and nausea
- Digestive issues: Vomiting, abdominal cramps
- Impaired immune function: Increased infection susceptibility
- Low blood sugar: Hypoglycemia
Excess Pantothenic Acid
Pantothenic acid is water-soluble, and excess amounts are excreted in urine. No upper limit has been established because toxicity from food or supplements is extremely rare. Even high-dose supplementation (1,000+ mg) typically causes only mild digestive upset in some individuals.
Common Questions About Pantothenic Acid
Do I need to supplement pantothenic acid?
Most athletes can easily meet pantothenic acid needs through whole foods. B5 is found in meats, eggs, dairy, vegetables, legumes, nuts, seeds, and whole grains. Supplementation is rarely necessary unless you're following an extremely restrictive diet or relying heavily on processed foods. A standard multivitamin typically provides 100% of the AI (5 mg).
How does pantothenic acid affect my training performance?
Pantothenic acid is converted to coenzyme A, which is required for the Krebs cycle—the primary metabolic pathway that generates ATP from food. Without adequate B5, your body cannot efficiently extract energy from carbohydrates, fats, or proteins. B5 also supports stress hormone production (cortisol) and fat metabolism during aerobic exercise, making it essential for both performance and recovery.
Can I get enough pantothenic acid from food alone?
Absolutely. A single breakfast of eggs (0.7 mg), yogurt (1.6 mg), and avocado (2.0 mg) provides over 4 mg—80% of your daily needs. Add mushrooms, chicken, or fortified cereal throughout the day, and you'll easily exceed 5-7 mg. The key is eating a varied diet of whole foods rather than relying on processed options.
Why is it called the "anti-stress" vitamin?
Pantothenic acid is essential for producing cortisol and other adrenal hormones that help your body respond to physical and mental stress. Without adequate B5, your adrenal glands cannot produce sufficient cortisol, impairing your stress response, recovery capacity, and overall resilience during intense training periods.
