Vitamin B5 (Pantothenic Acid)
An essential water-soluble vitamin crucial for energy metabolism, fatty acid synthesis, and hormone production
Quick Facts
Daily Needs
5 mg for adults, with variations based on age and life stage
Importance
Pantothenic acid is essential for energy metabolism, fatty acid synthesis, acetylcholine production, and adrenal hormone regulation.
Key Functions
- •Energy production from carbohydrates, fats, and proteins
- •Fatty acid synthesis and metabolism
- •Cholesterol production
- •Hormone synthesis (particularly adrenal hormones)
- •Acetylcholine synthesis (important for nerve function)
- •Vitamin utilization
- •Detoxification reactions
- •Red blood cell formation
- •Stress response support
- •Skin and mucous membrane health
Deficiency Signs
- •Fatigue and weakness
- •Irritability
- •Digestive disturbances
- •Burning feet syndrome
- •Numbness and tingling in hands and feet
- •Headaches
- •Muscle cramps
- •Increased susceptibility to infections
- •Nausea and vomiting
- •Poor coordination
- •Insomnia
Excess Signs
- •Diarrhea at very high doses
- •Nausea
- •Heartburn
- •Generally considered non-toxic even at high doses
- •Water retention (rare)
- •Abnormal liver function tests (rare)
Best Food Sources
- •Organ meats (liver, kidney)
- •Egg yolks
- •Avocados
- •Sunflower seeds
- •Mushrooms (shiitake, crimini)
- •Fish (salmon, trout)
- •Chicken and poultry
- •Sweet potatoes
- •Legumes (lentils, chickpeas)
- •Whole grains
- •Broccoli and cauliflower

Absorption Facts
- •Water-soluble - excess is excreted in urine
- •Absorbed in the small intestine
- •Absorption rate is typically high (50-90%)
- •Alcohol can impair absorption
- •Widely distributed in foods (name 'pantothenic' comes from Greek 'pantothen' meaning 'from all sides')
- •Less stable to heat and processing than many other B vitamins
- •Cooking can destroy 15-50% of pantothenic acid content
- •Freezing foods has minimal impact on pantothenic acid content
Special Considerations
- •Needs may increase during periods of stress
- •Athletes and physically active people may have higher requirements
- •May help with wound healing when applied topically
- •Therapeutic doses may help with certain skin conditions
- •Often included in hair and skin care products for its moisturizing properties
- •Higher doses may benefit rheumatoid arthritis symptoms in some people
- •Deficiency is rare due to widespread presence in foods
- •Works synergistically with other B vitamins
- •May reduce side effects of certain medications
