What
is it?
Pantothenic acid,
also known as vitamin B5, is a water soluble vitamin.
Functions
- what does it do?
Coenzyme
A. The
primary role of pantothenic acid is as part of coenzyme A, which
is involved in the release of energy from carbohydrates and
proteins, and in the breakdown and production of fatty acids. Coenzyme
A also makes other molecules more reactive.

| *Adequate
Intakes (AI) are used as no Recommended Dietary Allowance
(RDA) is established. The AI is a recommended
daily intake level based on observed or experimentally determined
approximations of nutrient intake by a group of healthy
people who are assumed to be maintaining an adequate nutritional
state. |

Limits (UL) = The maximum level of daily nutrient intake
that is likely to pose no risk of adverse effects. Unless
otherwise specified, the UL represents total intake from
food, water, and supplements.
ND = Not
determinable due to lack of data of adverse effects in
this age group and concern with regard to lack of ability
to handle excess amounts. Source of intake should be from
food only to prevent high levels of intake. |
