User Reviews for n-acetyl cysteine (nac)

NAC has many benefits but always causes an upset stomach whenever I take it. Ful, empty or anywhere in between makes no difference. Pain subsides after about 15-30 minutes.

I use this only for COPD. I take 500 mgs 3x a day. I find it very effective with no side effects. I may have no side effects because I don't take any Rx or OTC meds. I DO take herbs, but, so far, so good. Not one problem. I take Bluebonnet and Carlson.

NAC prevents my hair pulling- completely stopped it. Had to go to higher dose, 2000 mg morning, 1000 mg at noon, and 1000 mg evening. I also noticed improvement in concentration and memory. So, I increased the dose to 3000 mg morning, 2000 mg noon and 100 mg evening. Results are very good and no side-effects. However, NAC molecule has sulfur bond so the bottles should have odor; if not do not trust the company. I have found considerable differences in brands.

I used to get swollen ankles in hot days. I have been taking NAC 600mg in the morning with a large glass of tepid water for about a year and Last summer never got this worrying symptom at all. However it doesn't seem to have done anything for excessive mucus in throat and lungs, maybe I am taking a dose which is too low.

It is a lie to say NAC is available by prescription from a healthcare provider. It is not covered by insurances and pharmacies don’t carry it. This is a case of the FDA attacking CAM as lap dog to the pharmaceutical industry.

Asthma is a risk factor for adverse reactions to N-acetylcysteine and special caution should be exercised in its use. If you have asthma do not take. Look it up. Had me severely ill, coughing fits, acid reflux, vomiting, unable to sleep and this is still ongoing and from only take 5 pills for 5 days has left so much damage to me.

I took to clean out my liver & kidneys and I started coughing so much, stopped taking this as I associated the coughing fits with this and days later still coughing. I will never take again.

Had chronic coughing days after taking. It may have helped liver but not worth taking imo as i was trying to clear liver now bad coughing cant sleep. Then i read it promotes tumor growth. Be careful.

My GP likes prescribing NAC for bronchitis and other minor-but-annoying colds/flus with respiratory symptoms. Gives me a weird acid reflux reaction, but since I read up on NAC and wondered if the benefits were even measurable I did some comparisons with/without the last couple years when I'd have colds and my GP would prescribe NAC next to antibiotics, or NAC on its own (600mg tablets). The effect wasn't super strong, but my coughs were definitely more productive and I found it easier to breathe through the night when I had a cold or flu that left me phlegmy. It could just be placebo effect but I was doubtful of the efficacy since most legitimate medical evaluations of NAC seemed to just be "Well, it won't hurt." NAC seemed to help recovery by a day or two for my incidences of bronchitis but it's definitely not on the level of say- taking a strong steroid and feeling your sinuses just open up in 20 minutes.Read More Read Less

I'm in my 50's and I've never posted a review for anything before. I wanted to share my experience with NAC in an effort to help other people who might read this. Over ten years ago I experienced a severe anxiety attack (a first for me) while driving 75 mph on the interstate. I had a lot of stress in my life at that time and I guess it manifested in that attack. Ever since then I had been unable to drive on "open roads", interstate, or in any lane where there was oncoming traffic. I lived with this for over a decade. This was embarrassing to me and caused stress in my marriage, made work difficult, plus other negatives. I did not seek medical attention for this as I did not want to get prescribed meds or see a shrink (it's just not for me). In 2021 I started taking NAC after long study on its effects in making Covid symptoms less severe. I know some people don't agree that NAC has any effect on Covid symptoms, but I took it anyway. I also read that some people said NAC could help with anxiety. Well, after 3 months of taking 600mg of NAC every day, I noticed changes in my anxiety. I researched it more. Then I started rotating taking 1200mg one day, and 1800mg the next day, every other day like that. My anxiety is GONE. I now drive like I did over ten years ago. I feel like this stuff has almost saved my life - the normalcy I once took for granted I am SO SO thankful for now. I am not claiming that NAC will help anyone else with their anxiety problems, but I thought I would share my testimony here because it almost feels too good to be true, but it is. Thank God for NAC!Read More Read Less

NAC have done a lot for my hallucinations I.e Lights and stars. Mood and cognitive function was also increased in a positive way. I have not experienced any side effects i took 600mg 3x daily until symptoms disappeared. i take 600mg 1-2x daily now i don't take any medication

I have dermatillomania and my psychiatrist put me on 600 mg of it, and unfortunately my anxiety and panic went through the roof and double. Not sure why, I was a walking mental mess first time I tried this NAC.

I'm 60 yes of age. I've done construction for half those years. And experience shoulder pain here lately. After several months of nac. I notice one day the pain had stop. Not completely maybe a 0or 2 in pain. And I feel strong when lifting objects now. Not the weightlifter type. But feel a different my strength. I can say it definitely work for me

I was given NAC by my dermatologist for several types of physical urticaria I was experiencing; cold, heat, rubbing, etc. It was preventing me from being active because anytime I did anything I'd break out in these awful stabbing, itchy rashes all over my lower body. My derm gave me Jarrow 600 MG 1x a day 2+ years ago and it changed my life, worked almost instantly to a complete healing. I have also tried the NOW brand 1000 mg but it has not worked at all even when I doubled the dosage. I have to spend more but it's worth it to have a peace of mind so I can live. I have no idea why NAC works for me but it's been a life saver. Read More Read Less

Doc recommended for my trichotillomania and dermatilomania, with consistent use I pick/pull a lot less!!

I have chronic back pain and just recently had a compression fracture in my T6 vertebrae. So with that being said I am taking pain meds with acetaminophen daily. Some days less then others more when I am working. I started taking NAC for my liver and I actually have been feeling better. I also take SamE too which does help with pain too. It has given me a new lease on life. Right before the shut down I bought some extra. How can they sell an amino acid as a drug? This is an outrage and more studies should be done on how it is a possible treatment for Bipolar Disorder!Read More Read Less

Side effects for me are intense acid reflux and severe fatigue to the point I almost vomit. Indokt know if it’s because I am on Prednisone as well or if it’s just the NAC for me but this is only using 300mg.

I have had a productive cofing for a long time and succede to get rid of it by using acetylcystein ( water saluble tabl x 2 for 1 week)

I have been taking NAC for 3 months for a chronic cough due to radiation damage to my lung which caused fibrosis. I take it 2 times a day (600 mg) and it has stopped 95% of the cough.
