Respiratory problems are common in people with a weakened immune system. The primary cause of respiratory problems is the presence of pollutants in the environment. These substances trigger an inflammatory response that affects the respiratory system. If left untreated, these conditions can worsen and lead to serious complications. However, there are several nutrients that help maintain a healthy respiratory system. These micronutrients reduce inflammation and support lung health by reducing mucus production, strengthening cilia functions, or increasing immunity against pathogens.
Vitamin A
Vitamin A is a fat-soluble vitamin that has several functions in the body, including improving immunity, promoting eye health, and strengthening the respiratory system. Vitamin A deficiency is common and can lead to several illnesses, including respiratory problems. It is believed that the lungs accumulate vitamin A in the form of retinoic acid. This form of vitamin A is converted into retinol, which has several functions in the lungs. Vitamin A helps reduce inflammation and strengthens the immune system that fights against respiratory infections.
Vitamin C
Vitamin C is a water-soluble vitamin that is essential for maintaining a healthy immune system. It helps reduce lung inflammation and protects the lungs from oxidative damage. Vitamin C also strengthens the immune system and reduces the risk of respiratory infections. Vitamin C supplements are often used to treat respiratory infections, such as the common cold. While vitamin C may not cure these infections, it can reduce their severity by reducing inflammation and fighting against oxidative damage. Findings from a study suggest that vitamin C supplements, in combination with vitamin E, reduce the risk of respiratory infections and the severity of symptoms. Findings from another study suggest that vitamin C supplements reduce the risk of respiratory infections in women, but not in men.
Vitamin D
Vitamin D is a fat-soluble vitamin that has several functions in the body, including immunity and reducing inflammation. Vitamin D deficiency is common and can lead to several illnesses, including respiratory problems. It is believed that vitamin D has antioxidant properties, which help reduce lung inflammation. Vitamin D also strengthens the immune system and protects against respiratory infections. Findings from a study suggest that children who are exposed to higher levels of pollution have lower levels of vitamin D, which increases their risk of respiratory infections.
N-Acetylcysteine (NAC)
N-acetylcysteine is a naturally occurring amino acid that has several functions in the body, including reducing inflammation and strengthening the immune system. Studies suggest that NAC can reduce the risk of respiratory infections in children. In addition to improving lung function, NAC supplements have also been shown to decrease the risk of developing pneumonia.
Selenium
Selenium is a trace element that has several functions in the body, including strengthening the immune system and reducing inflammation. Selenium deficiency is common and can lead to several illnesses, including respiratory problems. It is believed that selenium has antioxidant properties, which help reduce lung inflammation. Selenium also strengthens the immune system and protects against respiratory infections.
Conclusion
Respiratory problems often occur as a result of a weakened immune system. This can be triggered by several factors, such as pollutants in the environment or a poor diet rich in inflammatory foods. Findings from different studies suggest that taking vitamin A, vitamin C, vitamin D, NAC and selenium can reduce the risk of respiratory infections in adults and children. Findings also suggest that vitamin A and vitamin C can reduce the severity of asthma symptoms in adults, while selenium and NAC can reduce the severity of symptoms in children.
