Certain nutrients have been found beneficial in the prevention and treatment of allergies. Often the intake of vitamin B5 or pantothenic acid brings great relief to the sufferer. This vitamin may be taken in a dose of 100 mg daily for a month. In such cases, liberal amounts of pantothenic acid helps even though the recovery takes several weeks. A dose of 400 mg of vitamin E taken daily for four to six weeks is also beneficial as this vitamin possesses effective anti-allergic properties.
