An adequate intake of vitamins and minerals is essential for the maintenance and promotion of healthy bodily systems. The respiratory system, most notably the lungs, needs special attention because of pollutants in the air and because of unhealthy actions. Smokers especially need to take extra care with their lungs and increase their nutritional requirements. For example, smoking increases the need for vitamin C by 30 percent, according to the Merck Online Medical Library.
Vitamin D
Vitamin D has anti-inflammatory and anti-oxidative properties which make it valuable in protecting the lungs from various environmental stresses and diseases. Vitamin D deficiency is also closely associated with chronic lung disease, according to a study published in the May 2009 issue of the "Canadian Respiratory Journal." People with asthma, chronic obstructive pulmonary disease, cystic fibrosis and interstitial pneumonia seem to be at an increased risk for the vitamin deficiency, although the reason for this has not been determined.
Vitamin C
Antioxidants, most notably vitamin C, are invaluable in protecting the lungs from the oxidative damage of free radicals brought on by environmental stresses or defective bodily inflammatory processes, according to an article published in the February 2001 issue of "Epidemiological Reviews." Vitamin C has been identified as the most abundant antioxidant in the fluid surrounding the lung and its alveoli. Vitamin C is also an immune boosting vitamin which helps combat respiratory infections and maintains proper immune cell functions in the lungs.
Magnesium
Magnesium is essential for lung health, according to the February 2001 issue of the Journal "Epidemiologic Reviews." Magnesium stabilizes the immune cells which become hyperactive to environmental and internal stimuli in asthmatics. Magnesium stimulates the dilation of the airways, making breathing easier, according to the article.
