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 just wanted to give a recent review, since I’ve seen many people saying their capsules had brown spots. Received my bottle today, and of course I was worried because my NAC sat in my hot mailbox for a few hours. To put you at ease, I carefully inspected the capsules, and they arrived all white. No brown spots. A silica gel pack is inside the bottle, & keeps it fresh. Please don’t throw it out! Always leave it in the bottle, and I advise to keep it refrigerated, to prevent any mold from forming. I bought NAC because it gets rid of bad Estrogen, and filters it out of the liver. It has many health benefits, and I can’t wait to see if it helps me too!

I’ve ordered this product twice now – once in January and once in May. The second time I ordered, the capsules had brown spots in them (not present the first time). From the research I’ve done, this could be a sign of moisture uptake and diminished biological activity.
I did notice that the issues I use NAC to treat got worse while taking the capsules with the brown spots, and as soon as I switched back to the first batch I ordered (I mistakenly bought more when I had some left), I felt better.
I would recommend this product, but be vigilant about returning it if it arrives with excessive dark brown spots in the capsules.

I am a regular customer and never paid or been solicited to offer reviews. I have loved this for at least 15 years and recommend it widely for liver repair & restoration and lung health. My son recovered from fatty liver disease in 3-4 mos. and lost a needed 30 lbs with this alone and no other diet changes about 13 yrs ago. I also order it for my son and his wife (and for others). We have NEVER had any of the “spotting” problems that are being reported. I am very sensitive to mold so that would be an important issue to me- but this spotting would be, if happening, oxidation issues-not mold.. There should be a slight sulfur smell to it as it is a component in the formulation of glutathione produced by the liver. (Sulfur is the reason MSM is so effective as well as a precursor to this process.) The bottle I am using now has been in my plastic set of supplement drawers in my kitchen since AT Least since July 2018…but not sure as I might have placed that order for my son so this could be older. The expiration date on this bottle is 5/2022. I am the only one using it at 1 cap /day so I expect it will continue to be fine probably for another 7-8 mos as my other bottles have been. I do not live in a dry climate, but in OR in the rainy Willamette Valley.

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.

Excellent supplement to protect and detoxify the liver from natural and synthetic toxins. Since using this supplement my migraine headaches have reduced in severity and frequency.

I was told to take NAC by a MD with holistic interests. The literature on the stuff is great. I take it regularly to prevent colds but even if I catch something I find I don’t feel as awful as I used to when sick as well as my colds don’t last as long. Additionally there is selenium in the product which has been doing wonders for my hair

I have been using NAC consistently for about a year. Somehow it keeps my mind focused and single-minded. In all the time I’ve been taking it has worked consistently. There are some concentration aids that lose their effectiveness over time, but the effect of NAC stable and predictable.
Are there any downsides? Well, I wish the effect keep my mind laser-focused would persist longer. On a typical workday, I’ll pop 6 of them.

I had those big tablets of NAC before with 1000mg and they were huge and too hard to swallow and plus 1000mg apparently is too much of a dose so I would chop them in half. These are 500mg and small pills with powder or something in them. Idk they work just as well if not better. I make better decisions on it and my thoughts aren’t as racy. Easier to control my thoughts, emotions, and over all I feel this is well worth the price I paid. Which to be honest I’m writing this at 3 am bc Amazon asked me to write a review while I was looking at stuff for my apartment, it just popped up like “You wanna review this or nah?” And I’m like sure why not, it’s helped me. Anyway I can’t remember how much I paid. 10? something like that. Worth it. Okay bye.

Most of my family takes this product- (that’s 8 of us). It’s used for OCD, in doses of 1200-1800mg., It’s best taken in an empty stomach, an hour before food or two hours after eating. When using 1800mg. per day as we do, divide them into dose of one 600mg. capsule an hour before breakfast and 2 600mg. caps before bed. It has been clinically studied to be an effective natural option to treat Trichotillomania (Hair Pulling Disorder). It has made a world of difference for my daughter with autism, and her OCD behaviors. It can also be used as a pre-hangover remedy, instead of the mini pack pills or drinks you see at the liquor store that taste horrible. NOW NAC has no taste. Take 1 600mg. capsule with your first drink and 2 capsules after your last drink. I only drink 1-2 times a year, but it makes a big difference for us light weights. NAC can also save your life! It has been a long standing IV treatment in Emergency Rooms for Acetaminophen toxicity. The uspharmasist.com website states:
US Pharm. 2014;39(3):HS2-HS8.
ABSTRACT: Acetaminophen toxicity is one of the most common causes of both intentional and unintentional poisoning in the United States. Acetaminophen-associated overdoses account for approximately 56,000 emergency department visits, 26,000 hospitalizations, and over 450 deaths annually. Acetaminophen-induced liver toxicity has become the most common cause of acute liver failure and the second most common cause of liver failure requiring transplantation. The recommended dose of acetaminophen in adults is 650 to 1,000 mg every 4 to 6 hours, not to exceed 4,000 mg in a 24-hour period; in children, the recommended dose is 10 to 15 mg/kg every 4 to 6 hours, not to exceed 50 to 70 mg/kg in 24 hours.
This actually happened to a loved one of mine who had extreme tooth pain. He didn’t have dental insurance at the time, and was looking rather sickly after a day of dosing intermittently with RX strength Ibuprofen and RX strength Acetaminophen every 4-6 hours. As soon as I suspected he’d had taken too much medication, I went on the internet on the internet for side effects of the drug’s toxic levels. Ibuprofen can cause stomach upset, potential for ulcers, and it thins your blood, but nothing compared to Acetaminophen. Since NAC is a treatment in the thousands of milligrams an ER, I had him take 3600mg. of NOW brand NAC, and rushed him to the hospital. They gave him mega milligrams of NAC through an IV. The ER docs said that they’d never seen someone’s blood clear the whopping 8000mg. of Acetaminophen toxicity in under 6 hours, and without any liver damage. They said that had he waited even a half hour more, and not taken the NAC immediately at home, he would have had irreparable damage to his liver. Thank God we had it on hand!! They also told him that can never consume Acetaminophen again in his life and and should list it as a life threatening allergy in his medical records and on his phone. It may be less expensive elsewhere, I don’t know because when you’re happy, why risk trying other brands? I trust NOW supplements for their purity, and use at least 10 other supplements they carry on Amazon.

This is an excellent product with very helpful reviews from incredibly thoughtful people. Amazon consumers are too savvy to be so alarmed by a simple color change in a capsule. It is obviously competitors propagating the bulk of these “mold scare” reviews. NOW has always been a reputable company that stands behind their products. I have received nothing for this review I’m just a loyal customer, seeking knowledge and good health.
Cappygal –
I don’t know if these do anything for me. Got them for my cough/cold, can’t tell if they helped it go away or if it went away naturally. Then I kept taking them for mood because it is supposed to help with anxiety/depression, but yeah still haven’t noticed a difference. Owell. :/
Also everyone complaining about ‘mold’ needs to actually read the product description before buying lol. It’s not mold. Chill.

NOT moldy people….brown and black spots are the normal reaction from the sulfuric properties of this supplant. I’ve researched this extensively and it can and probably will happen to your NAC supplement no matter which brand you purchase…not a defect.

I originally posted a review saying I was also getting mold spots. But I actually bothered to contact the company. After reading their response I have upped my review to four stars. Here is what they had to say:
Last year NOW switched to new vegan based NAC raw material that consists of selenium and molybdenum compounds.
These capsules are more prone to speckle under certain conditions. Over time when kept in a humid environment, such as a kitchen or bathroom black spots may appear in NAC.
This is a normal oxidative reaction among the ingredients, but the product is safe to consume.
These spots are NOT mold or any other micro-contamination. Micro-testing has been performed to assess product safety.
To slow down this process, please either refrigerate or freeze the bottle.

This was recommended by two psychiatrists (one I know personally and one I know professionally) for impulsivity, skin pucking and so on related to bipolar I, OCD. I have been taking it for a few years along with other medications. I really notice a difference. I have used this brand since the start. Good value for the price. I have never had any issues with the quality. Research supports it’s potential benefits for this. It doesn’t eliminate the issues, but seems to assist with lessening the intensity, frequency and duration of them. Only down side is you have to take it a while before it really benefits.

I tried this product because I have trichotillomania. A compulsive hair-pulling disorder! I have had this disorder since I am 13 years old. I’ve never gotten a day of rest from it since that day. I am now 50 years old. I recently read some information about this vitamin and started taking it several months ago. I never knew that a chemical imbalance in my brain could also contribute to compulsive hair-pulling. When I take that vitamin I never even think about my hair. I never have any urges. It never crosses my mind to pull my hair. My friends and my family have noticed that I am not pulling my hair and they have said that I look fantastic! For anybody that suffers from trichotillomania I highly highly recommend this vitamin! It will change your life!!!!
Amazon Customer –
Great product. I’ve taken since 2016. Brown/black spots not mold but chemical reaction reference additional items in capsules according to NOW foods. Google them and you will see information on their interaction

I started using this 2 months ago my main reason was to help with endometriosis. I heard from a few bloggers that it can help with the pain and irregularities of your period when you take it. The first month went by and to my surprise my period pain was cut in half. Still painful but not as bad as without it not to mention my period came on time. If you have endo you know that the period pain can last very long sometimes the whole period. This past period my pain lasted 4 hours then the rest was a breeze compared to what im used to. In addition my children caught the flu im usually the first one to get their germs but this time i had no symptoms i didnt even get sick. Plus before i started taking nac i was using the pill to help with pain but i hated how emotional i was. This also got rid of anything left in my body from the pill and everyday i felt more like my non emotional self! After 2 months of taking it i can surly say its a maricle pill it did what i wanted it to do and more!!! The reason i am giving this a 4 is because 2 days ago I noticed that now when i took it i had the worst tummy ache ever for a few hours. Then i checked the bottle and noticed little blackish spots on the pills so i had to throw it out (i kept the little fresh package inside the bottle and kept it in a dry place!) so i am currently seaching for another brand since the past reviews mention this as well.
Amazon Customer –
I would give these 5 stars if they had lasted more than a month. I had bought them and only took a few of the pills before I noticed they had started to mold inside the capsules. Little spots of black mold showed up only a few weeks after opening. I have a lot of supplements in my medicine cabinet and for some reason these are the only pills that have molded. I am very disappointed because the whole bottle has to be thrown out. I hope the next bottle will last a bit longer.
