Vitamin C helps protect smokers' lungs from oxidative damage prompted by tobacco smoke. A study published in the American Journal of Respiratory and Critical Care Medicine found that smokers who received high doses of vitamin C had less oxidative damage in their lungs compared to those who did not receive vitamin C. Vitamin C is known to be an effective antioxidant, and this property helps protect the body from damage caused by reactive oxygen species which are produced during metabolism or as a result of exposure to environmental toxins such as tobacco smoke. Vitamin C is also important for the synthesis of collagen, a protein that is essential for the health of connective tissues in the body.
