Protection against oxidative stress is crucial in lower respiratory tissues involved in oxygen exchange. N-acetylcysteine (NAC) is a precursor of the antioxidant glutathione, and is effective for supporting the bronchopulmonary tissues and supporting general well-being. BronchEze includes additional classic antioxidant support nutrients such as vitamins C and E, carotene, riboflavin, and selenium, many of which may be insufficient in Western diets. These nutrients also help maintain optimal immune system function. Horehound and licorice extracts, and thyme oil, are traditional botanicals and tonics for lung support.*
