The importance of vitamins & supplements for asthma sufferers

People with asthma are often deficient in key nutrients and therefore vitamins and supplements can be used to complement conventional asthma therapy and hence ease the symptoms of asthma. Below are some of the vitamins and supplements you may want to consider.

Vitamin C and asthma

Vitamin C

Vitamin C is needed for defending the body against pollution and infection and enhances the human body immune system. It can also help to reduce reactivity in the lungs when in contact with allergens and can be particularly beneficial for exercise induced asthma. Vitamin C is found in fresh fruits and vegetables such as apples, carrots and tomatoes.

Vitamin B6

Vitamin B6 helps to maintain a biochemical balance in the body and can help to reduce the wheezing that asthma sufferers have which in turn can help to reduce the severity of asthma attacks.

Vitamin B12

Supplementation with vitamin B12 can help alleviate and improve asthma by reducing its severity and frequency. This is especially the case in children. Foods that contain B12 include milk, liver, hard cheese, beef, eggs and fatty fish.

Vitamin D

A report in the Journal of Clinical Investigation published in December 2005 revealed that taking Vitamin D could help to improve the effects of steroid drugs used to treat asthma.


Magnesium can help regulate smooth muscle contraction and relaxation which can help prevent attacks.

Gingko Biloba

Gingko Biloba, a Chinese herb, may also be effective, as it will enhance your breathing and help with your bronchial reactions.

When deciding which vitamins and supplements to take you must ensure that you discuss this with your medical professional and never stop taking medication prescribed for asthma without consulting your doctor.
