Pantothenic Acid (B5)

Pantothenic acid, or vitamin B5, is an essential water-soluble vitamin that plays a central role in cellular energy production. It's a precursor to coenzyme A (CoA), which is critical for metabolizing fats, carbohydrates, and proteins, as well as synthesizing hormones, neurotransmitters, and cholesterol.

Found naturally in almost all foods ("pantothenic" means "from everywhere"), B5 is particularly abundant in organ meats, egg yolks, avocados, and whole grains. True deficiency is extremely rare in developed countries, but some practitioners suggest that stress, processed food consumption, and certain medications may increase requirements beyond typical dietary intake.

Pantothenic acid has an excellent safety profile with no established upper limit. As a water-soluble vitamin, excess amounts are readily excreted in urine. Even at very high doses (10+ grams daily), side effects are rare and typically limited to mild digestive upset or diarrhea. No serious adverse effects have been documented in the literature.

• No significant drug interactions - B5 does not interfere with medications
• B-complex synergy - Works well with other B vitamins
• Biotin interaction - Very high doses may theoretically compete with biotin absorption, though this is not clinically significant at normal supplemental doses

General health: 5-10 mg daily (adequate intake is 5 mg for adults)

Stress support: 100-500 mg daily in divided doses

Skin/wound healing: 200-500 mg daily

High-stress periods: Up to 1000 mg daily, though evidence for benefit at these doses is limited. Most people get adequate B5 from a quality B-complex supplement.

Very affordable supplement. Basic calcium pantothenate typically costs $5-10 per month for moderate doses (100-250 mg daily). Higher-potency standalone B5 supplements range from $10-15 monthly. Often more economical as part of a B-complex formula.
