N-Acetyl-Cysteine (NAC)

This page goes into how NAC can be a game-changer for those with COPD.


I just started it myself and I feel it is making a difference. Hoping to see still more improvement as I continue. I take it along with vitamin C and MSM. All three boost glutathione, the body's master antioxidant. People with COPD have a lot of oxidative stress and are glutathione deficient.

  • My pulmonologist has had me on 1000 mg a day for almost three years. It definitely helped to stabilize my lung function for a couple of years and reduced the mucus and cough.

  • Thanks for sharing. I'm a little confused. It worked for a couple of years? Sounds like you stopped taking it--if it was working, why stop?

  • No, I'm still taking it, but I've had a rapid loss of lung function in the last six months (bronchiolitis obliterans) and I am now actively awaiting a double lung transplant. I've continued with the NAC through all of the pneumothorax episodes and pneumonia. Without it, I'm not sure I would still be here. Absolutely no coughing or mucus today, just low lung function. Merry Christmas and may God bless you in the coming year.

  • I'm sorry about your low lung function but glad NAC has been helpful with the coughing/mucus. I found a page at Earth Clinic about your condition, if you want to check it out.


    High dose vitamin C could be very helpful as well. It has been called "the primal panacea."

    Do you eat ice cream? I was reading about how ice cream containing artificial flavors can cause a lot of sinus and lung issues.


    "Over the last several years, California health officials have been tracking a handful of workers in flavoring factories who have been incapacitated with a rare, life-threatening lung condition 'bronchiolitis obliterans' for which there is no cure or treatment. Usually found only in people who are poisoned by chemical fires or chemical warfare or in lung transplant patients, bronchiolitis obliterans renders its victims unable to exert even a little energy without becoming winded or faint."

    "The airways to the lung have been eaten up," said Barbara Materna, the chief of the occupational health branch in the California Department of Health Services. "They can't work anymore, and they can't walk a short distance without severe shortness of breath."

    Seven flavoring-factory workers in California are known to have the disease or similarly serious lung damage, and 22 others have had lung tests come back with abnormal results..."

    I rarely eat ice cream myself and when I do, I look for organic brands like Three Twins.

    Holiday/Healing Blessings to you.

  • WHAT IS NAC? Everyone Merry Christmas and Happy New Year.


  • Here's the link again that I included in my first post. Also a quote.


    "With its ability to reduce oxidative stress and simultaneously quash chronic inflammatory changes, NAC is emerging as a game-changing therapy in COPD. A randomized pilot study of adults with acute exacerbation of chronic bronchitis and positive bacterial culture in the sputum demonstrated that 600 mg of NAC twice daily led to a near doubling of the rate of bacterial eradication compared with standard therapy, while reducing the number and duration of acute exacerbations and improving quality of life.35 NAC treatment of patients with moderate-to-severe COPD improved their physical performance on lung function tests, especially after exercise.37"

    Only started taking it recently and I can feel it is helping with the coughing and congestion. Finally something that works! Merry Christmas and Happy New Year!

  • Where do you get NAC ???

  • I got mine in bulk from BulkSupplements, at Amazon. amazon.com/BulkSupplements-...

    There are many other brands. Should be available in health food/supplement stores.

  • Great Stuff. I have been on NAC 600 2 daily 1 am 1 pm and it has just about stopped the exacerbation's. Been on for about 4 months. I have COPD 4 th stage.

  • Awesome, thanks for sharing!

  • Hi I ordered NAC from amazon and my reflux got worse so I stopped. Has anyone had that issue with NAC?

  • It can get worse in the beginning, it is detox symptom. I'd keep going.

    Here is a testimonial at Earth Clinic.

    5 out of 5 stars

    I am 63 and have severe COPD from smoking since I was about 16. I've had chronic bronchitis for a number of years and recently found some articles on using N-Acetyl Cysteine (NAC) for clearing phlem, so I bought some from a local health food store. I've been taking 1200mg/day and am amazed at the results - after just one day I was coughing up a lot, but the phlem was foamy rather than thick and sticky. It's been over a week now that I've been taking the NAC and my coughing has lessened significantly. I am now also taking serrapeptase and niacin.

    I was recently given a nebulizer machine by someone who's friend passed away from his COPD (he was 81 and had three nasty bouts of pneumonia) and have ordered some hoses/mouthpieces and some liquid DMSO, MSM and colloidal silver to try Ted's DMSO treatments to further help clear my lungs. I'll post an update after a few weeks.
