Finally, some people use it to lower blood cholesterol levels.

It is recommended to take between 300 and 1000 mg of vitamin B5 a day, although the dosage may vary depending on the context.

Always consult a doctor before taking any dietary supplement.

Vitamin B5 deficiency

Vitamin B5 deficiency is extremely rare because it is found in most foods.

However, some experimental studies suggest that pantothenic acid deficiency may be responsible for muscle fatigue, burning feet and hands ("burning feet" syndrome), severe fatigue and nausea.

Excess vitamin B5

There is no scientific evidence of any risk from taking too much vitamin B5.

There is no upper limit or dangerous dose.

Vitamin B5 and other B vitamins

To do its job well, vitamin B5 needs all the other B vitamins to be present in optimal amounts.

A deficiency in one of the B vitamins can cause dysfunction on many levels.

In addition, the consumption of alcohol or oral contraceptives can reduce the absorption of pantothenic acid and increase the need for it.

It is a water-soluble vitamin belonging to the B group.
