It works great for someone needing extra help to clear lungs to breath, my mother has been on oxygen for over 15 yrs. it’s not a miracle drug, but definitely something that helps.

I’m under 50, don’t smoke, and I was told I have either chronic bronchitis or copd. Last winter I had a very difficult time breathing due to cold air and lack of humidity. I had to get on steroids and use a nebulizer to get through the winter…..I was essentially unable to function for six months. I started taking this product and so far and it has tremendously helped with breathing issues.

Makes skin issues better. Fades dark spots and redness and helps hair grow when tsken with myo inositil

So grateful I discovered this. I’ve been taking NAC for 8 months and it has really helped me to improve my ocd behaviors and skin picking. When I first started it made me feel very tired and hot, but that has since gone away. I’ve tried both the tablets and the capsules from NOW and for me personally the tablets seemed to work better. I take this with my doctors approval in conjunction with an SSRI and adhd medicine, both which make my skin picking urges worse, and it’s really make a significant difference in the negative side effects of those. I am beyond happy with the changes as I probably would have stopped the other meds by now.

It was hard to tell if the NAC was working. But after almost 2 months the results are in.
My waistline has shrunk 1.5 inches. And I haven’t lost any weight.
First, I have three medical conditions that crank up my stress. So no matter how much I meditate, no matter how many adaptogenic herbs I take, no matter the lifestyle, my stress levels will be high and stay that way.
What about NAC? NAC is N-acetyl-L-cysteine. It is one of the necessary precursors to glutathione. Glutathione is THE MASTER STRESS ENZYME. It regenerates all of the other stress control/antioxidant enzymes in your body. In times of stress, you can strip all of the glutathione in your body. When this happens, it sure is nice to support your glutathione.
Do you need anything else for glutathione support? Yes. I recommend magnesium glycinate. You need magnesium to produce all those stress enzymes in the body and in times of stress, you can burn through all your magnesium too.
Anything else? oh ARRGGG! Glutathione is made from NAC (you got), glutamate (go get), and glycine (you got from the magnesium glycinate).
So why is losing 1.5″ from the waist a good sign that NAC is working? Stress puts fat around your waistline. And it won’t budge. I lost 50lbs about 2 years ago but my waistline dropped from 36″ to 34″. 20 years ago, my weight was the same but my waistline was well under 30″. I have a big ole stress belly I do.
And, alas, alas, since this stress is triggered by my genetics, I’m stuck taking NAC for the rest of my life.
That was a couple of years ago. Then my doctor suggested I try taking 2.5 – 3.0 gm per day. After about a month I noticed my compulsions were gone. I was left with the odd sensation of having nothing that needed doing. I was not sure I liked it so I stopped the NAC and boom! compulsive as ever. Back on compulsions gone.

This product helps with chronic cough. My husband does not take meds but will take this as it works for him. It shortens my cold by days. I feel great relief with it.
TubalCane –
This product has helped curve my addiction and OCD tendencies. Not a CURE but has helped tremendously. Anyone with a drug, alcohol or gambling addiction should consider trying 2000-3000 mg a day of NAC!
Deborah –
I’ve been taking NAC for a couple of years now. Before I started taking them… i suffered from severe bronchitis at least twice a year that always lasted two months or more with two rounds of antibiotics each time. NAC, I believe, has protected me from getting it as often and nowhere near as severe. I’ve had it once and instead of 2 rounds of 10-14 days antibiotics it was one antibiotic for 3 days. I ran out and forgot to reorder… I feel I’m getting it again. I’m reordering NOW!

I’m only 32 but have lost a lot of weight (on purpose) and do not drink on a regular basis. So when I have a night at a party, I struggle hard core the next day – I have always had bad hangovers but I could barely drink 4 beers over an afternoon/evening without being hungover – before this product. Now I take one when I start drinking and one before bed. No more headaches and zombie walking the next day. Allows me to still get a good nights sleep after a night out – still don’t drink a lot compared to my friends but I can now tolerate having 4 beers without being useless the next day.
Gigi Aharoni –
fantastic 1000 mg 3x a day for OCD symptoms, stress, etc. life changing.
Chucho –
Really noticed a difference in lung function improvement this winter when I had bronchitis. Seemed to be a synergistic improvement when I started taking it with the bronchial dilator I had been using. The tickling/rasping in one side of my lung airways dramatically improved over 2 weeks. It is a good mucus thinning supplement.
The reason I didn’t give it 5 stars is that (as with most supplements) there is no qualitative, traceable documentation of raw material sources/3rd party analytical testing of the product. Unfortunately, most supplement vendors do not provide any objective analytical documentation of their products.

Has brought my liver tests down and into the normal range. Will keep using

I am a big fan of any supplement that is suppose to do good things, and this is one of two that I take. The National Institute of Health. GOV website lists a wide range of benefits of N-Acetylsyteine, and if they say it’s good I’m inclined to believe them. I am 43, do not have any health issues currently and hope to continue being well, and count on this powerful antioxidant to keep me that way. For added clarification to those who are researching this for the first time- NAC is a precursor to glutathione, which your body makes naturally, but the reserves can get depleted for one reason or another. Glutathione is a free radical scavenger (free radicals are bad things that age you and your body) and create inflammation. Inflammation is the root of many health issues. At the risk of sounding preachy I will stop now but do the research, I think you’ll be amazed.

NAC (N-Acetyl Cysteine) it’s considered semi-essential because your body can produce it from other amino acids. Namely methionine and serine. It becomes essential only when the dietary intake of methionine and serine is low. NAC is the most powerful antioxidant and free radical scavenger. I take this daily, the pill is easy to swallow, it has little to no smell. I feel great. I hope you have great results while taking this also. This is an honest and true review. I was not paid, nor did I receive free products in exchange for my opinion or review. Shann?

I took this 1x per day as I developed long haul covid. Also took Vit C and Vit D 1000 IU. Many viral infections cause inflammation and cellular oxidative stress. ROS or reactive oxygen species bounce around our cells and damage proteins, mitochondria, and DNA. The SARS CoV2 virus is especially likely to cause disregulation in the oxidative/reduction system of our cells since it takes out the ACE2 receptors on endothelial cells. Glutathione is the key enzyme to decrease ROS and decrease oxidative stress. NAC supplements increase Glutatione.
Anyway,my long haul covid symptoms of fatigue and headaches gradually decreased over several months. I started 16:8 time restricted eating, 2 weeks later I had my last headache. I could do long hikes, but with pronounced fatigue the next day. I did a four day water fast to promote autophagy and recycling of damaged proteins and mitochondria. It seemed to work. After that, no fatigue post multiple day hikes or backpacking!
Good for minimizing covid19 symptoms and very helpful to recover from long haul covid.

NAC has so many benefits but I use it for OCD. It takes my OCD from a 9/10 to a 6-7/10 which is a GIANT difference for me. I take 2-3 grams a day. I like to use on an empty stomach. I take 1000mg in morning when waking up and then 1000-2000mg around 8pm. I’ll probably take NAC for the rest of my life and the NOW brand has the best deal on it. They have a little bit of a sulfur smell but that’s completely normal, so don’t worry. Give it a try, at worst, you’re out $15 but they have been a game changer for me!

I began taking this now NAC 100mg supplement 3 times a day in addition to taking the Now Glycine powder twice daily about August 1st. It is now mid-September & I am so happy to write that the Now Glycine powder taken twice daily as well as taking the Now NAC 1000 mg x3 daily has brought about results for me that feel like a true miracle. My depression is gone, zero panic attacks, and zero anxiety. My psychologist who has conducted Cognitive Behavioral Therapy Sessions with me weekly for nearly 5 years was so amazed at my results from this Glycine & the NAC that he began taking both daily. He has experienced the same stunning results I have! I have not been solicited to write this review, offered no free bottles, or gain anything by writing this. Do your research. Go to the website PubMed & enter NAC. Nearly 900 studies will pop up. Why don’t more professions recommend this? I wish I could tell everyone who suffers anxiety, depression, insomnia, and panic attacks what these two cheap, safe supplements can do to finally rid you of misery. To date, I have lost 24 lbs. Okay, yes, the weight loss is wonderful, but even better is the quality of my life has improved beyond belief.
NAC is powerfully effective for a plethora of illnesses & physical as well as emotional conditions. Good grief, it is even clinically proven to be effective to help poor drug addicts be successful in maintaining their sobriety.
Side effects? The only thing I noticed was more frequent bathroom visits during the first 2 weeks. NAC is clinically proven help flush out unhealth fats via the fecal route. (Again, see the website PubMed.) But again, that was normalized for me after 2 weeks. And because of the remarkable effect on my depression, metabolism, anxiety, and insomnia from the Now NAC & Glycine, I would continue to take both of these if I had to live in the bathroom.

Full disclosure: I’m not a healthcare professional. As such this supplement, or any other for that matter, should not be used to diagnose or treat any physiological issue, disease or symptom. As always, consult your healthcare professional.
That said, I was using a Pulmocort Flexhaler twice a day for asthma. I adhered to MANY lifestyle changes that ultimately helped me over time, inclusive of NOW Supplements, NAC (N-Acetyl-Cysteine) 1,000 Mg, Free Radical Protection, 120 Tablets.
I no longer use Pulmocort. In fact, the only exogenous modality I DO use, is NOW, NAC. My lungs are clear.

I have been taking this for 1 month at 3x a day 1 pill each time so 3,000mg total. I have noticed in the last two weeks that OCD thoughts are gone. I also have tried every prescription with no success. It helps somewhat but not reliably with stress and it helps somewhat with disordered eating patterns (mainly obsessions around this so Im more flexible). One thing it doesn’t help with is depression but that’s a different issue. I am also on a low dose mood stabilizer too but that hasn’t been working for a long time so I doubt it has anything to do with this supplements success. I’m planning to get off it so I can update then. The taste is fine no smell. The pill is a little large but well coated and easy to swallow. The only side effect I got was a lot of burping (no smell) initially but this side effect has worn off mostly at the 1 month mark. I love that I can take this otc, it’s safe for pregnancy so don’t have to worry about taking a break when I do that, and natural. Recommend!

Anybody else here experience fat loss, like really quick? My weight stayed the same yet my lovehandles were gone in less than a week. I have also noticed an increased clarity of thought and my anxiety has really settled down. Its not gone, but the ups and downs have been SEVERELY deminished. I’m glad to see other reviewers experiencing the same benefits as I was thinking that what was happening was too good to be true.
Alexandra Bradshaw –
I’ve struggled with trichotillomania for nearly 20 years and NOTHING has even remotely worked to control my urge to pull and pick at my hair and skin. After doing some research into NAC for body focused repetitive behaviors, I decided to give it a try. I’ve been taking 1000mg or 1 tablet per day for about 3 weeks now. I would say I’ve noticed about a 90% decrease in the urge to pull my hair or pick at my skin. For those others out there who suffer from the same issue, I urge you try it. Amazing so far. Will continue to take and update with any changes. Wow.
Shannon K. –
When I first got this I was skeptical. I wasn’t sure that NAC was going to do anything. Well let me tell you it does! 24 hours later and my anxiety was at an all time low. The stress I normally keep in my shoulders was gone and I felt muscles that I’ve never felt before. If I don’t take this every 24 hours I start to feel it in my back and notice my mood shifting. This really works for me and I hope it works for you too! FYI I take this with chellated magnesium to help with absorption, also you might want to consider GABA as well.

This supplement has been a god send. After horrible side effects from vraylar and being petrified to try again with other meds, I was desperate and began looking for something natural to help my depression . I stumbled across this and the reviews were awesome. For $15 bucks I threw caution to the wind and ordered this! Holy happiness! I felt so much better after only 5 days the weepy, crying crap left the premises! Wahoo! I can smoke again and enjoy life! Complete game changer! I then told a friend about this and she started using. Only a few days later she reported to me she was feeling so much better! I could hear it in her voice when I called her. I can’t say enough good things about this stuff!! Get it now!! Do not wait!! ❤️❤️❤️❤️

This product significantly helped clear my lungs by taking it twice a day when I was sick with an awful virus in November. Seriously when you are up days and night’s coughing endlessly and can’t sleep try this — it’s not why I had it in my cabinet but just gave it a shot. I take it daily now to help clear general congestion from allergens etc and should I contract corona at some point this will be in my arsenal of defense! Breaks up mucus, helps stop the post nasal drip that triggers the cough and clears congestion from the lungs.

After starting a new medication I developed (or had an increased) issue with skin picking. It had become unbearable as the skin around my fingernails was constantly bleeding, my face looked terrible, and I would find every skin imperfection. My psychiatrist recommended trying NAC to see if it helped. I started taking 1000mg per day for the first 2 weeks and then moved up to 2000 and will likely increase again. Although it hasn’t completely stopped the problem I am seeing huge improvements and it seems to be constantly getting easier to avoid. I probably would have stopped taking a medication that I really need if it hadn’t been for NAC. The pills are a bit large but are surprisingly easy to swallow since the coating is so smooth. They have a kind of weird taste but it isn’t very strong and goes away quickly. I’ve started taking them with my breakfast smoothie which completely masks the flavor so I’m sure taking them with something other than water would have a similar result.
Maui Doug –
I’ve taken other, similarly priced, capsule forms at the 600mg level for a year or so. I recently had a gum infection around a forward molar anchoring a bridge. My hotshot dentist had done a root canal on the tooth and as I have extremely deep roots, probably didn’t get deep enough and anyway there are branched nerve pathways they can’t get that also can become infected. My gums were bleeding over the holidays and on Maui, many take their annual vacations this time of year. I put Triple Antibiotic on the area, gently rubbing it in and around and it helped a little, but as not intended as an oral topical, I had to spit it out every 10 minutes or so.
I was low in my other brand NAC, so took a large dose, 4 x 600 mg capsules and the bleeding and pain subsided a little. 4 hours later I broke out the NOW NAC and gulped when I saw the size and smelled the tablets. I took 4, 2 at a time and within 2 hours all symptoms of infection, pain, bleeding and tenderness vanished! I MEAN TOTALLY VANISHED!
I’d been rinsing with diluted 3% Hydrogen Peroxide and nursing this thing for a week and it was only getting worse! I worry about oral infections, especially in the upper jaw as they are tooo close to the brain and mastoid process. Historically people have died from toothaches that got badly infected! Our Creator designed our bodies to work very well against invaders if we have the proper inputs and I’m using these big hulking tablets from now on! GLUTATHIONE RULES! AND ADDING GLUTATHIONE DOESN’T WORK – WE HAVE TO GIVE OUR BODIES NAC, THE PRECURSOR AND IT IS MANUFACTURED PER NEED TO FIGHT INFLAMMATION AND ASSIST INTRA-CELLULAR ACTIVITY.

N-Acetyl Cysteine or NAC is an amino acid valued primarily for its role in antioxidant production. Along with two other amino acids: glutamine and glycine, NAC is needed to make and replenish glutathione. Glutathione is one of the body’s most important antioxidants, which helps neutralize free radicals that can damage cells and tissues in your body and very important for liver function. Buy the Glycine and take it along with NAC 2 x day on empty stomach as a boost for a few months in a year. Glutamine powder comes in a large tub, you mix with juice or protein shake (low sugar or no sugar!), and drink right after exercise to build muscle. You can continue indefinitely with all 3, or just do boosters twice a year for 1-2 months stretch. I use Glutamine all year after my workouts. DO NOT EAT SUGAR DRINKS OR CARB LOADS, THEY ARE VERY DAMAGING TO BODY. Sugar will age you and destroy your body. Cut back drastically. No point taking supplements then canceling all that work with sugar in your drinks. I use Stevia – just a pinch.
NAC is good for lungs as it acts as an expectorant, loosening mucus in your air passageways. As an antioxidant, NAC helps replenish glutathione levels in your lungs and reduces inflammation in your bronchial tubes and lung tissue.
NAC is a chelator of heavy metals. In other words, NAC binds to toxic heavy metals such as mercury and lead, and removes them from the body. NAC is one of the most effective oral chelating agents. Taken regularly over a period of time, NAC will remove many toxic heavy metals from the body.
I take it for lung, kidney, liver support, lowering blood pressure, and increasing glutathione levels in body. Take this twice a day, or less. My advice is to use this as a booster for 1-2 months twice a year. It also lowers anxiety and helps sleep. Take on an empty stomach between meals.

I take two a day. After six months I’m off my metformin. Need I say more?
Sarah –
Honestly I was skeptical. I’ve been pulling my hair constantly since I was five years old and nothing ever helped. I heard about this after seeing it on reddit and thought what could it hurt. I’m a terrible pill taker. I can never remember to take them. However about three times a week I do remember so I take two or three at a time and I’m still seeing results. I’ve been taking them for about three months with this erratic schedule and have experienced no side effects. Except for walking out of the shower one morning not seeing a bald spot at all and crying. But that doesn’t count. I highly. HIGHLY. recommend these.
Jeremy M –
I take one every day and it has been very helpful for my anxiety, it’s pretty much nonexistent now. Would recommend to anyone struggling with anxiety and I’m definitely gonna continue taking this supplement. As far as the immune system benefits go, since taking it I got sick, got over it quick but I’ve had a cough for the past month. So I honestly don’t think the immune system benefits are that good but that’s not why I take this supplement.

Aside from the other health benefits of this Amino Acid, it detoxes the liver and helps to metabolize alcohol. It also cuts down on the cravings. Take this one hour before you start drinking. This is a game changer. It will help you drink less. It seems to block the mental processes that drive the need to drink more and more. The supplement NAC is an effective preventive measure for hangovers. N-acetylcysteine and alcohol metabolism are closely connected. The supplement increases the production of glutathione in the body. Glutathione is needed to break down acetaldehyde, a toxic substance that is produced when ethanol is broken down by the liver. Acetaldehyde is responsible for liver damage and many of the worst symptoms following alcohol consumption. The best thing for a hangover would, therefore, be something that gets rid of acetaldehyde. NAC does this by increasing glutathione levels in the body. This supplement has strong antioxidant and anti-inflammatory properties. It can decrease alcohol-induced free radical damage. In fact, N-acetylcysteine is used for medical treatment of acetaminophen (Tylenol) poisoning because of its protective effect on the liver.
B. Sigmon –
I bought this to help clean out the Tylenol I take seeing I take a lot for my pain. I had been taking a lot for many years and wanted something to maybe help ease the damage if any. I only take like one or two a week. it does mess with my finger nails. I hardly ever take Tylenol style products now. went total disable. a little time after taking this I got my first and only itty bitty kidney stone. oh was it a pain. I believe it was because of this product working with other to break down the bad stuff. cannot prove it, just what I believe. non doctor writing this opinion, I just know my body. but as always make sure to check with your doc and listen to your body, never hurts to talk with your pharmacist if you take meds and vitamins
Craig from Long Island –
This stuff is being recommended for everything from OCD and other psych issues to respiratory and immune challenges. Read up on it. It’s non-prescription, and not every doctor is that familiar with it.
Far from snake-oil, NAC is getting a lot of attention in the medical and psych communities. It’s been an amazing product for us.
Evan T –
It never occurred to me to leave a review for this, but I feel that I must. I’ve been taking NAC (specifically this brand) at 2000mg per day for about a year now and within the first week I completely stopped biting my nails.
I didn’t even notice I wasn’t biting them anymore until I thought about it at the end of the first week and realized my nails had actually grown out and needed to be cut.
So if you’ve got a chronic nail biting problem, grab this, and I suggest taking 2000mg a day and kick that nasty habit once and for all. Hope it works for all of you, too! Enjoy!
Also, this supplement is supposed to be amazing for other things as well, but you’d have to do your own research into what those other benefits are because I use it strictly for my nail biting habit (but it does help with old drug habit cravings as well.)

I’ve had chronic bronchial issues for most of my life, but they have increased in severity as I’ve gotten older (I’m over 50). I’ve never been a smoker, but grew up in a home with parents who both smoked, and I am a singer and musician who performed in clubs for many years before the indoor smoking bans. I stumbled upon NAC doing an internet search for natural bronchitis relief. I’ve been taking it for about a month now, and within the past couple of weeks the difference is remarkable! I went from struggling to take a deep enough breath to sing a line of music, to being able to breathe deeply enough to hit notes I haven’t since I was in my 20’s! I take one tablet in the morning with my coffee, and one at night with a glass of water before bed. I’m not exhausted all time anymore, it’s amazing how much more you can accomplish when you can actually breathe!!

I suffered from recurring eye infections and blepharitis and spent tons of money at the eye doctor every few months. He just kept prescribing ridiculously expensive eye drops that only helped for a while and I wanted a CURE. So, I began researching. My eyes constantly watered to the point I couldn’t even wear mascara because it was pointless. Prior to the watering eyes situation, I had extremely painful, dry eyes and used drops constantly. Turns out that non-stop watering eyes is a symptom of dry eyes. Who knew? Anyway, I started taking 2 of these NAC twice daily and the watering stopped and the Blepharitis is GONE. Now I only take 1 per day. It makes me sad that the doctors push expensive prescriptions that only offer temporary relief when you can be healed using an inexpensive supplement. Also, NAC appears to have many, many benefits. Google NAC (or N-Acetyl-Cysteine) benefits for more info.
Rob Lauzon –
This important chemical diminishes as we age. Our body finds it harder to create it from other amino acids. I enjoy my scotchs and bourbons so this is critical in my life. It is the ingredient my liver uses to break down the alcohol I drink. I do not want my Liver or Kidneys failing !

As a Nutritional Specialist, this is one of the products I recommend to my clients when they have difficulty losing weight on their diet and workout program. It’s one of the ways that’s safe and effective to help ensure your liver can process fats for energy efficiently.
RBW –
not necessarily the effect I wanted. I was hoping for increased energy and a calming of the mind. I have been taking it for about 5 or 6 days, I think I skipped one day. One thing I’ve definitely noticed is my appetite has gone up and I can’t seem to stop eating which is not normal for me. And it’s making me feel kind of sluggish, the opposite of the energy boost I was hoping to get. I couldn’t get through my 2 mile run without stopping to walk because i was just too tired. Anyway, I’m stopping them for now. Perhaps I’ll try a lower dosage at some point. Can these pills be cut up to get a smaller dose?

Use this for my PCOS, so far so good.
