Vitamin
B5
Common
Name: Vitamin B5
Synonyms: pantothenic acid
Vitamin B5 - pantothenic
acid - is required for:
Vitamin B5 plays an important role in the secretion of hormones, such
as cortisone because of the role it plays in supporting the adrenal
gland. These hormones assist the metabolism, help to fight allergies
and are beneficial in the maintenance of healthy skin, muscles and
nerves.
Pantothenic acid
is also used in the release of energy as well as the metabolism of
fat, protein and carbohydrates. It is used in the creation of lipids,
neurotransmitters, steroid hormones and hemoglobin.
Some are of the
opinion that pantothenic acid is also helpful to fight wrinkles as
well as graying of the hair.
Deficiency of
vitamin B5:
With Vitamin B5 in short supply symptoms like fatigue, headaches,
nausea, tingling in the hands, depression, personality changes and
cardiac instability have been reported.
Frequent infection,
fatigue, abdominal pains, sleep disturbances and neurological disorders
including numbness, paresthesia (abnormal sensation such as "burning
feet" syndrome), muscle weakness and cramps are also possible
indications that this nutrient is in short supply.
Biochemical changes
include increased insulin sensitivity, lowered blood cholesterol,
decreased serum potassium, and failure of adrenocorticotropin to induce
eosinopenia.
Dosage:
The dosage underneath is the Recommended Dietary Allowance (RDA),
but be aware that this dosage is the minimum that you require per
day, to ward off serious deficiency of this particular nutrient. In
the therapeutic use of this nutrient, the dosage is usually increased
considerably, but the toxicity level must be kept in mind.
No recommended
dosage but 10 - 100 mg is indicated.
How Much Pantothenic
Acid Is Enough:
Lack of pantothenic acid in the diet is rare, so there is no recommended
daily intake for this vitamin. Often, pantothenic acid is included
in B-complex multivitamins. Normal daily intake of pantothenic acid
for adults is 4 to 7 milligrams.
Toxicity and symptoms
of high intake:
It does not appear to be toxic in high dosage, although diarrhea,
digestive disturbances and water retention have been reported on dosage
exceeding 10 g a day.
Taking 1,500 mg
a day over an extended period may cause sensitivity to the teeth.
Best used with:
It is most effective when taken with the B group vitamins, Vitamin
A, vitamin C and Vitamin E
When more may
be required:
People under stress, prone to allergies, consuming alcohol or eating
too many refined foods might develop a shortage of this vitamin.
Enemy of vitamin
B5:
Pantothenic acid can be lost in cooking - particularly with roasting
or milling, as well as when exposed to acids like vinegar, or alkali
such as baking soda. It is also destroyed to a large degree in canning.
Other interesting
points:
Do not add soda to the water when cooking vegetables - it will destroy
the pantothenic acid.
Food sources of
vitamin B5:
Beef, brewer, yeast, eggs, fresh vegetables, kidney, legumes, liver,
mushrooms, nuts, pork, royal jelly, saltwater fish, torula yeast,
whole rye flour, and whole wheat.
