Vitamin B5 — dosage, safety & deals FAQ

How much Pantothenic Acid do you need per day?

No RDA exists; the Food and Nutrition Board found the data insufficient to derive an EAR, so it set Adequate Intakes (AIs). The AI is 1.7 mg (birth-6 months), 1.8 mg (7-12 months), 2 mg (1-3 years), 3 mg (4-8 years), 4 mg (9-13 years), and 5 mg for ages 14+ (both sexes). Pregnancy is 6 mg; lactation 7 mg. — per the NIH Office of Dietary Supplements; general information, not medical advice.

Can you take too much Pantothenic Acid?

The Food and Nutrition Board was unable to establish a Tolerable Upper Intake Level because there are no reports of pantothenic acid toxicity in humans at high intakes. Some people 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; general information, not medical advice.

What are the signs of Pantothenic Acid deficiency?

Deficiency is rare except in people with severe malnutrition. It is associated with numbness and burning of the hands and feet, headache, fatigue, irritability, restlessness, disturbed sleep, and gastrointestinal disturbances with anorexia. Deficiency is usually accompanied by deficiencies in other nutrients, making the effects specific to pantothenic acid difficult to identify. — per the NIH Office of Dietary Supplements; general information, not medical advice.

Who is most likely to need more Pantothenic Acid?

People with a mutation in the pantothenate kinase 2 (PANK2) gene are the group most likely to have inadequate pantothenic acid status. Many PANK2 mutations reduce the activity of pantothenate kinase 2, potentially decreasing conversion of pantothenic acid to CoA and thus reducing CoA levels; these mutations cause the rare, inherited disorder pantothenate kinase-associated neurodegeneration (PKAN). — per the NIH Office of Dietary Supplements; general information, not medical advice.
