Formerly known as vitamin B5, pantothenic acid is essential to almost all forms of life yet there is still much to discover in understanding this vitamin. It is not one of the ‘Big Four’ B vitamins (thiamin, riboflavin, niacin and folate) and is not used to fortify drinks or cereals so you won’t hear much about it even though it’s vital to good health and growth in children.
Pantothenic acid is involved in the metabolism of carbohydrate, fat and protein for energy. It is needed for the production of key players in the body including:
The Adequate Intakes (*AIs) for pantothenic acid per day are:
1.7 mg for infants (0-6 months)
2.2 mg for infants (7-12 months)
3.5 mg for children (1-3 yrs)
4 mg for children (4-8 yrs)
4 mg for girls (9-18 yrs)
5 mg for boys (9-13 yrs)
6 mg for boys (14-18 yrs)
4 mg for women (19 to 70+ years)
5mg for pregnant women
6mg for breastfeeding women.
6 mg for men (19 to 70+ years)
Note: mg = milligrams

*There are no RDIs as there are with better-known vitamins so an Adequate Intake (AI) figure is given instead.
An upper limit hasn’t been established for this vitamin but 1000 mg a day is considered a prudent maximum intake.
Commonly, whole grains, chicken, beef, potatoes and tomatoes are major contributors to pantothenic acid in Western diets. Here’s a list of 20 of the richest food sources of pantothenic acid:

Food | Amount (mg) |
60 g lamb or chicken liver, grilled | 4.5 |
12 0g grilled Atlantic Salmon (3.6 mg), served with salad using half an avocado (0.8 mg) and toasted bread roll on the side (1.5 mg) | 6.0 |
Mini cheese platter with 50 g soft white cheese (1.5 mg), 100 g fresh bread (1.5 mg), 30 g each of pecans (0.5 mg) and raw cashew nuts (0.6 mg) and 30 g dried apricots (0.2 mg). | 4.3 |
Two poached eggs (2.2 mg) served with 100 g stir-fried mushrooms (2.2 mg) | 4.4 |
2 wholewheat breakfast biscuits (1mg) topped with 25g unprocessed wheat bran (0.65mg) and 150ml milk (1.25mg). Served with a drink of chocolate beverage base using 20g malted base (0.35mg) and 150ml milk (1.25mg). | 4.5 |

Naturally occurring pantothenic acid deficiency is very rare in humans and is only seen in experimentally induced cases or in malnourished individuals. Interestingly, during World War II, some prisoners in Asia experienced ‘burning feet’ syndrome whereby they had numbness, tingling and painful burning in their feet. This was a result of pantothenic acid deficiency.
Here are the tell tale sign of pantothenic acid deficiency:
Most of what we know regarding the effects of pantothenic acid deficiency comes from experimental research in animals.
Rats that were fed a pantothenic acid deficient diet ended up with grey hair, yet no connection has been found with this vitamin in determining the colour of human hair.
Pantothenic acid is one of the constituents claimed to be responsible for the health benefits of royal jelly but remember royal jelly contains bee pollen and may trigger life threatening allergic reactions in susceptible people.
