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.*'Dietary ConsiderationsWheat FreeDairy/ Milk FreeSoy FreeYeast FreeSugar FreePreservative FreeSalt FreeCorn FreeFree of Artificial Colors/Flavors'Serving Size:6 Vegetable Capsule'Servings Per Container:30 '' Amount Per Serving Vitamin C (ascorbic acid) 500'mg 'Vitamin E (natural d-alpha-tocopheryl acetate) 200'IU 'Vitamin B2 (riboflavin) 10'mg 'Selenium (L-selenomethionine) 50'mcg 'Horehound (Marrubium vulgare)* 1500'mg 'Natural Beta-carotene 600'IU 'N-Acetyl-L-Cysteine 600'mg 'Licorice Root (Glycyrrhiza glabra)** 200'mg 'Thyme Oil (Thymus vulgaris)*** '''Other ingredients: cellulose, hypromellose, water ''''Suggested use for adults: Six capsules daily, in divided doses, or as directed by your health care practitioner.This product is intended for professional use and is manufactured under strict quality control to ensure the optimum in purity, potency and reliability.
