The Food and Nutrition Board was unable to establish a (UL) for pantothenic acid because there are no reports of pantothenic acid toxicity in humans at high intakes. Some individuals taking large doses (e.g., 10 g/day) develop mild diarrhea and gastrointestinal distress, but the mechanism for this effect is not known — per the NIH Office of Dietary Supplements.

Because some pantothenic acid is present in almost all foods, deficiency is rare except in people with severe malnutrition; the only individuals known to have developed it were fed diets containing virtually no pantothenic acid or were taking a pantothenic acid metabolic antagonist. The one group noted as most likely to have inadequate status is people with a pantothenate kinase 2 (PANK2) gene mutation causing the rare inherited disorder PKAN. Deficiency is associated with numbness and burning of the hands and feet, headache, fatigue, irritability, restlessness, disturbed sleep, and gastrointestinal disturbances with anorexia — per the NIH Office of Dietary Supplements.

Almost all plant- and animal-based foods contain pantothenic acid in varying amounts; some of the richest dietary sources are beef, chicken, organ meats, whole grains, and some vegetables. It is also added to various foods, including some breakfast cereals and beverages such as energy drinks. The food highest in pantothenic acid listed is beef liver (8.3 mg per 3 ounces), followed by fortified breakfast cereals, shiitake mushrooms, and sunflower seeds — per the NIH Office of Dietary Supplements.
