N-Acetyl Cysteine (300 mg)
I have been taking N-Acetyl Cysteine (300 mg) for 2 years as recommended by my lung specialist. It has really made a difference in my life allowing me to participate in more activities with my children and grandchildren. I have COPD and if I miss taking the NAC I can really tell a difference and I have more difficult breathing. N-Acetyl Cysteine (300 mg) is a great product!
