When a person inhales, their lungs absorb oxygen from the air to carry through to their bloodstream. The lungs release carbon dioxide when an individual exhales. Some manufacturers of vitamins claim products can reduce the symptoms of respiratory conditions and improve breathing patterns, but there is little medical evidence to support this.



Lung health

Several factors can increase a person’s risk of developing lung disease, including:


older age

genetics

smoking

exposure to harmful substances, such as asbestos and radon gas

chronic conditions, such as heart disease and diabetes

The American Lung Association (ALA) provides tips that can help individuals keep their lungs healthy. These include:


Avoiding smoking: Cigarette smoking increases the risk of lung cancer, chronic obstructive pulmonary disease (COPD), chronic bronchitis, and emphysema. People who smoke may have difficulty breathing, as the cigarette smoke narrows their airways.

Limiting exposure to indoor and outdoor pollutants: Chemicals a person may use at home or work, and outdoor environmental air pollution can damage the lungs. The ALA suggests people exercise indoors when there are high pollution levels outdoors.

Preventing infections: A person should wash their hands with soap and water or use alcohol-based cleansers to avoid infections. It is best to avoid crowds during the cold and flu season.

Getting regular checkups: Individuals should speak with their healthcare professional regularly to ensure their lungs are healthy and evaluate their breathing patterns.


Vitamins and lung health

Some vitamins claim to benefit the lungs. The British Lung Foundation (BLF) notes that all adults, including individuals with COPD or bronchiectasis, can take vitamin D supplements to reduce their chance of developing chest infections. However, there is no strong evidence to support this. Additionally, doctors may advise against taking these supplements if a person has sarcoidosis.


Researchers of a 2017 review found that people can use vitamin D as a complementary therapy to manage their asthma. However, there is limited research on this aspect.
