Pantothenic acid adequate intake

RDA have been established for many essential nutrients however, present knowledge of human nutritional needs of pantothenic acid and biotin is incomplete. Therefore, to ensure adequate nutrient intake, obtain the recommended allowances from as varied a selection of foods as possible. Nutritionists suggest that dietary planning include regular intake of each of the four basic food groups ... 

Adequate Intake For some vitamins, notably biotin (Section 11.5) and pantothenic acid (Section 12.6), dietary deficiency is more-or-less unknown, and there are no data from which to estimate average requirements or derive reference intakes. In such cases, the observed range of intakes is obviously more than adequate to meet requirements, and the average intake is used to calculate an adequate intake figure. 

From the limited studies thathave beenperformeditis notpossible to establish requirements for pantothenic acid. Average intakes are between 2 to 7 mg per day. This is obviously adequate, because, as discussed previously, deficiency... 

Pantothenic acid is ubiquitous in plant and animal tissues and especially abundant in foods rich in other B vitamins. No RDA has been established, but a daily intake of 5-10 mg is thought to be adequate for adults. Deficiency in humans is unknown. 

Pantothenic acid, also called vitamin B5, is a water-soluble vitamin. The average adequate intake of pantothenic acid for adults is 5mg/day (Food and Nutrition Board 1998). 

For some nutrients, such as the vitamins biotin (section 11.12) and pantothenic acid (section 11.13), and a number of trace minerals, deficiency is unknown except under experimental conditions. For these nutrients there are no estimates of average requirements, and therefore no reference intakes. As deficiency does not occur, it is obvious that average levels of intake are more than adequate to meet requirements. For these nutrients there is a range of intakes that is defined as safe and adequate, based on the observed range of intakes. 

Pantothenic acid deficiency safe and adequate levels of intake... 

There is no evidence on which to estimate pantothenic acid requirements. Average intakes are between 3 and 7 mg/day and, as deficiency does not occur, such intakes are obviously more than adequate to meet requirements. 

RECOMMENDED DAILY ALLOWANCE. The amount of pantothenic acid required by human beings has not been determined so, a recommended daily allowance for pantothenic acid has not been made by the Food and Nutrition Board of the National Research Council. Nevertheless, they do give "estimated safe and adequate intakes" beised on proportional energy needs (see section on VITAMIN(S), Table V-5, Vitamin Table). Further, they suggest that a higher intake may be needed during pregnancy and lactation.
