Acetylcysteine "I'm female, mid-30s. Started taking this when I had COVID as I am prone to developing ARDS. I read that NAC can help boost immunity and repress inflammatory overreaction. I did not develop ARDS. I can't say for certain that the NAC prevented it. I will say, however, that wheezing and chest tightness stopped, fever went down, and I began to recover within 24 hours of starting the NAC. I stopped taking it for a while. Later I started taking it daily for 4-6 months. Stopped recently due to medical issues. Results: 1) (neutral) At last 2 med checkups BP was 95/66 and 106/60 (usual 125/80) 2) (negative) Started having severe palpitations, iron deficiency worsened, odd results on metabolic panel. 3) (positive) I did not catch stomach flu or colds that others in my home had."

Acetylcysteine "Gave me bad acid reflux, coughing, and I later found out it exacerbates asthma, had me so sick. Will never take again. Also read online NAC exacerbated tumor growth in lung cancer and melanoma. It may help some, but if you have asthma, be cautious. Wish I had read before taking. Don't let the good reviews fool you."

Acetylcysteine "I've now been taking NAC 650 mg in the evening for 2 weeks. I suffer from chronic depression and generalized anxiety. It helps to stabilize my mood, and it definitely helps with anxiety. I thought I should perhaps take a small break, and yesterday I skipped the pill. I woke up feeling quite sad, and in a couple of hours, the anxiety started to get stronger. I gave up the idea of a break and took one NAC pill right away. After a while, I felt a lot lighter. What surprised me is that my singing voice suddenly improved a lot. I have suffered from voice issues. I think NAC helps with acid reflux, lungs, and mucous membranes. Also, anxiety and stress relief helps. I hope this doesn't wear off, as all the other supplements have done so far."

Acetylcysteine "I take this for COPD. I am wheezing constantly. After regular use of NAC cysteine, it helps a little, reducing mucus but creating a difficulty in breathing and wheezing daily. Whereas this did not happen before taking this drug, I revert back to MSM powder with vitamin C liquid and feel better."

Acetylcysteine "I've taken it off and on for a few years, for its antioxidant effects initially, and the past couple of years for lung support, as my asthma tries to blossom into COPD. I take 600 mg once daily. Seems to help, doesn't hurt, with one exception. If I take it daily for more than a couple of weeks, it aggravates a pain in my left calf that is also aggravated by consuming generous amounts of smoked meat (yes, really). My doc has no idea what's up with any of this, but isn't worried. My present hypothesis is nitrogen sticking with endothelial tissue in a vein. Oh, aging is SUCH fun!"

Acetylcysteine "I had taken NAC a few years ago to help repair damage in my body caused by taking the very strong antibiotic cipro. It helped to restore cell damage and I tolerated it well. With the flu hitting close to home, I decided to take it again as a prevention, but within a few days I started having terrible acid reflux and just a feeling of unwellness."

"NAC is scientifically proven to raise glutathione levels, and that's why I take it, for liver support. I take a low dose as recommended by my doctor, he says most people take way too much. It does have some side effects, one is an acidic stomach, the other is that it makes me tired. I've switched my dose to nighttime with food. He said it will take months for it to work, so stick with it, so I am. Good science behind this supplement!"

"I was struggling to breathe with COPD and using inhalers continually. Doctor prescribed these tablets - 1 to be taken 4 times daily. Almost immediate relief. I cannot believe how much they improved my breathing by clearing mucus from my lungs. Fantastic!!"

Acetylcysteine "I wanted to share my experience with using NAC as part of my approach to managing high cholesterol. After researching potential solutions, I incorporated Nutraharmony's NAC into my routine. I've been taking NAC for a while now, and it seems to be contributing positively to my cholesterol management journey. While it's not a one-size-fits-all solution, I've noticed some improvements. So, I will continue to monitor my results."

Acetylcysteine "Used NAC with quercetin to reduce COVID symptoms. It definitely helped since I took blood thinners and was unable to have the recommended shot. No negative side effects, 600 mg twice a day. It does smell terrible."

"Lungs were clear-no problem before starting NAC pills. I took it to clear out my liver for 4 or 5 days, now I have a chronic cough, feels terrible. I'm coughing while typing this :( and I also read afterward that this med promotes cell growth as well as tumor growth as it doesn't distinguish the two, so be careful. Wish I never took it!"
