Great product! Works to reduce cough and phlegm better than Claritan or any other product. We used to have to take prescription drugs when experiencing a cold or allergy symptoms, but no more. We were told about this product by a respiratory therapist who is asthmatic and treats others who are (plus those with cystic fibrosis). He swore by this product. My husband was recovering from long bout of pneumonia, still coughing constantly. He spent nights in a recliner as his cough was so bad. Even codeine cough syrup wasn't effective, As soon as he started taking this product, the cough was cut short and after the first DAY taking it, he slept in the bed for the night without coughing! We are sold on NAC. Amazon has a MUCH better price than a health food store.

THIS STUFF WORKS!! We both started taking it to prevent winter colds/flu and for Seasonal Affective Disorder (SAD), common here in the Pacific NW when winters are just long, dark and depressing. We both noticed a mood boost within just 2 days of starting it and it also makes you feel more alert and just more able to handle everything. MAJOR difference. Added bonus: we haven't had ONE cold, flu, or sinus infection all winter and we would have normally had at least 1 or 2 really BAD sinus infections by now for sure. I take 2 tablets in the morning with my coffee and feel the effects for at least 4 or 5 hours. If taken before a workout it gives you energy and helps burn fat more effectively so I use it for that also. Just don't take before bed as it's an "upper". I've since learned NAC is good for SO many things including PCOS, Weight Loss, Cold/Flu, Depression, Anxiety, Addiction, OCD, Anti-Oxidant, Anti Aging, Metabolism Increase and more - that I can't believe we don't hear about this stuff all the time. Why is that?? Anyway, I tell all my friends about it now and will continue taking this after winter ends. We love it - IT WORKS.

I love what this supplement has done to help with my mucus/allergy problems. I take it twice a day and since reading an recent article by Dr. Mercola citing other benefits, I may increase the dosage.

My Dr. recommended I try NAC as a treatment for "picking disorder". (if you don't know what that is, congratulations, you don't have it) The first brand of NAC I tried seemed to help a little (Piping Rock brand I think it was) When I ran out of that I tried this product (Now Brand NAC) What a difference! After just 1 week I feel I may be cured! One word of warning...though it says nothing on the label about taking this product with food make sure you eat something with it. If you don't you're going to spend an hour or 2 feeling like there's an alien in your stomach trying to get out!

This helps take the edge off my OCD.

I have trichotillomania. It helps immensely. I've tried so many psych meds, I never thought anything would work. Since day 1 of taking NAC, I barely have the urge to pull at all. I wish I would've tried it sooner, but for some reason I was skeptical bc it's so affordable and doesn't come from a prescription. If you're suffering, please have faith and try it out.

I'm a skeptical RN and have a younger brother whose heart nearly conked out on his when he was 50, and now he's 55 and doing better than ever, after a scare last year, when he hit a bad patch of life stress. His doctors told him he might need a second surgery but he has 5 kids, some of which are still at home. So they made him do a medical management plan vs another surgery. BUT IT WORKED, he has now been taking this and 3 other supplements and chelation IVs once a month and his heart disease has been 90& reversed. He's lost 60 lbs w diet modification, and he credits these Amazon products with unclogging his cardiac arteries. Now I'm taking these and the others his cardiologists ordered for him. It's all about reducing inflammation, and I say this as an RN for 39 years. So much misinformation out there, but this is working for us.

I have COPD.....seems that they are helping my lungs a bit.....not as much mucus...any improvement makes me more comfortable....will re-review in a few months...Update..... just purchased 2d bottle.....great product ,very little mucus really helps me breathe better

In case you didn't hear... this supplement is currently showing aid in the improvement of symptoms of m.s. in laboratory testing!

I suffer from OCD and social anxiety, and NAC really helps with both of these conditions. NAC also seems to lift depressive moods. Physically, I feel healthier too. As with most nootropics, I take this first thing in the morning on an empty stomach. I feel the effects after about 10 minutes to an hour, and I continue to feel them all day to some degree until bedtime. My personal experience with this product: Pro’s: -HUGE reduction in anxiety -HUGE reduction in “ruminating thoughts” (anxiety or distress over past events or mistakes) -HUGE increase in focus and productivity -Overall sense of well-being, reduction in depression -Increased creativity Neutral: -Colors seem brighter -HUGE increase in libido (may be a pro or a con for you) Cons: -NAC is very stimulating for me. One time I took it before bed, and it took me much longer to fall asleep. Now, I simply never take it before bed. -I can’t lie, NAC sometimes makes me feel “weird” but it not unpleasant, but I do not take it daily for this reason. I simply cannot deny that there is a change in consciousness, but it is nowhere near the change that you would experience from a low dose SSRI, for example. Finally, There is no denying that NAC helps tremendously with alcohol hangovers. I typically take 2 right before I go to bed after drinking (this is the only time I take it before bedtime). I used to get headaches that last for several days after drinking, but this product pretty much eliminates these. Some people have said that they take NAC before drinking, and I’ve noticed that when I do this, it typically takes 3x as much alcohol to get the same effect. This may be a placebo however. I put this at the bottom because I don’t want to encourage unsafe drinking habits. Some people experience a reduction in asthma symptoms, but I did not notice any change. I have Samter’s Triad so maybe I am not a good one to assess this benefit as we tend to not respond to conventional treatments. Overall I strongly recommend this product.
