3 vitamins may play a role in reducing asthma

Some scientists believe that asthma and vitamin deficiencies are closely related, so researchers have studied the role that certain vitamins - such as vitamin D, vitamin C, and vitamin E - play in the occurrence and severity of asthma. While it is clear that diet influences the occurrence and prevalence of asthma, what is Less clear is whether vitamin supplements can prevent asthma or improve its symptoms.

Asthma and vitamin deficiencies


The hypothesis, according to verywellhealth, is based in large part on the high rates of asthma in Western countries, where diets rich in refined sugar, fats and processed foods have led to widespread deficiencies in certain vitamins, including vitamins D and B complex.

Vitamin D


Vitamin D is a fat-soluble vitamin that is absorbed from sunlight by cholesterol in the skin. The vitamin is also found in dairy and other foods. It helps strengthen the adaptive immune response. It is part of the immune system that aims to identify disease-causing microorganisms. Some of them, such as respiratory viruses, cause asthma attacks.

Several studies have suggested a relationship between vitamin D and asthma, with a study published in the journal Cureus concluding that a daily dose of 500 IU of vitamin D may reduce the severity and frequency of asthma attacks in children.

Other studies have suggested that vitamin D may prevent the development of childhood asthma, although the evidence supporting these claims is generally weak.

Vitamin C


Vitamin C, a water-soluble vitamin found in many fruits and vegetables, especially citrus fruits, is touted as a defense against colds and free radicals that cause long-term damage to the body's cells.

Vitamin C has anti-inflammatory and antioxidant properties that may benefit people with asthma, and it has been suggested that vitamin C can reduce oxidative stress on airway tissues which in turn may reduce hypersensitivity to common asthma triggers.

Vitamin C may also reduce inflammation and hypersensitivity in the same way that inhaled steroids used to treat asthma work.

So far, however, the evidence to support these claims is weak. However, there is evidence that taking a daily vitamin C supplement may reduce the risk of developing a viral respiratory tract infection in people at high risk of asthma attacks.

vitamin e


Vitamin E is a fat-soluble vitamin found in nuts, seeds, oils, and green leafy vegetables. Many people take vitamin E supplements as a preventative measure to lower the risk of a wide range of disorders, including heart disease, cancer and Parkinson's disease.

Vitamin E has anti-inflammatory and antioxidant effects that may benefit people with asthma, and most evidence is based on studies showing a direct relationship between vitamin E deficiency and asthma severity.

A study published in the American Journal of Respiratory and Critical Care Medicine suggested that the use of infant formula fortified with vitamin E or OR may reduce childhood asthma, while also suggesting that vitamin E deficiency in mothers may increase the risk of asthma in children.
