## Questions & Answers

**Q: Is this the acetylated form of  glutathione?  Thank you.**
A: NAC, as far a I know, along with glycine and glutamic acid are the building blocks of glutathione.  Glutathione is not easily absorbed in a supplement, so NAC was recommended to me.  Not many foods contain large amounts of cysteine (an amino acid), but many contain the others mentioned above.  That's why I take NAC, so that my body can increase its production of glutathione.  I am not a nutritionist, though, so you'll have to check elsewhere as well.

**Q: Is this plant/food base or a cheap synthetic version???**
A: http://www.nowfoods.com/NAC-600-mg-100-Veg-Capsules.htm.  Should not matter if it is made from plants, food, or chemicals.  It is an amino acid in a very specific form.  So long as the bottle has the NAC and not some crap, then you are good.  It is GMP quality assured, which is the industry oversight group that supplements wanted to use over the FDA.  So it should be NAC, I use it all the time.

**Q: Where, what country, are now nac manufactured?**
A: My container, purchased @ Amazon Feb 08, 2015 says: "Manufactured by NOW FOODS395 S. Glen Ellyn Rd., Bloomingdale, IL 60108, USA. For more product information visit www.nowfoods.com/0086"I will purchase this product again from Amazon. Don Welton

**Q: why is jarrow nac better than now nac?**
A: In my opinion neither is a quality product.  NAC should have a distinct odor you notice as soon as you open the bottle - a rotten egg smell.  Neither of them has this.  There is not odor even if you open the capsule, and no rotten egg taste.

Try Solgar.

### ⭐⭐⭐⭐⭐ Good liver and immune support
*by I***T on February 24, 2026*

Keeps me staying healthy and with my liver disease works well for me and my wife been taking it for years

### ⭐⭐⭐⭐⭐ Supercharge your liver and say "goodbye" to hangovers...
*by K***S on July 4, 2016*

*Overview* In a few words, I can say that this supplement is the closest supplement I've ever used to a miracle product. Why do I say that? As a precursor to glutathione (Coined “The Mother of All Antioxidants” by Mark Hyman, MD), NAC serves to help my body overcome environmental and dietary toxins. In brief, I no longer feel "sluggish" like I once did or experience hangovers (even from minimal alcohol) like I once did. Since taking 1200-1800mg/day (2-3 capsules) in September of 2015, this has become a (long-awaited) staple in my supplement drawer and boost to my overall health. I am never without this product. *Dosage* I take, like I said, 2-3 capsules a day. First thing in the morning on an empty stomach with a large glass of water. Second one around lunchtime. Third one middle of the afternoon or so. If I plan on going out for a few drinks in the evening, I take another one before heading out the door to spend time with friends. I rarely miss doses but if I do, it is not as if my whole system crashes or I feel I have become so dependent on it I cannot function or am worse off than when I started. *What does it do?* If you're interested in the breakdown of what exactly this product is meant to do, I would recommend your own research or read some of the other reviews. I merely want to offer my own experience. I have taken a variety of supplements since I was a teenager (15+ years) and never really felt that most products lived up the hype or could back up their claims. As a former smoker, I stumbled across this product while researching "What products help mitigate lung damage from smoking" and found this on a random forum buried somewhere in the text. That's where I first encountered the name NAC. I was skeptical and more than a little nervous about taking it but was somewhat assured when I read this is used in hospitals for acetaminophen overdoses so, if used by the medical community, maybe there was something to it? The effect was initially subtle. I was bursting with energy or bouncing off walls but found certain things that used to be VERY hard for me started to lift. A few examples. I found myself picking up the phone more often and calling a friend where before I felt a dark lining on life that made it harder to be myself. I found myself breathing easier and experiencing less sinus pressure (which makes sense as this thins out mucus) which was hugely helpful as I am allergic to most everything and experience an overload. It didn't take all allergy symptoms away, but my need for anti-allergy meds has decreased. In fact, I can't remember the last time I bought a bottle of allegra. I found myself able to better focus in class and while I still experience a certain level of brain fog from time to time, clarity of thought is more the norm for me than the exception. This has corresponded to a lifting of a sense of depression and darkness making it easier to be myself in social situations (and move past the worst parts of social anxiety). Last, but certainly not least, I process alcohol WAY faster. I can't explain the effect but, like most adults, I have a drink from time to time. Like some adults, I have nights where I have more than one drink from time to time. Unlike most adults after a night of drinking, I don't have concerns for how I'll feel the next day. I can feel the effect even at the bar where I remain lucid and focused while drinking as opposed to becoming...sloppy? In the last year I've woken up with a headache once as opposed to formerly experiencing a headache after 1 beer. So...it seems to be doing something... Like I said, I cannot recommend this product enough and continue to share my experience with everyone I encounter. While I continue to experiment with other supplements, adding or removing items for specific things, NAC remains a baseline of health for me and will not go without. No, my hair has not fallen out (as another reviewer mentioned they experienced). No, this product will not allow you to drink like a monster without effect at all. Qualifiers aside, this product might help you and would be worth considering if you've tried everything out there (like me) and want a good baseline for health to continue to build upon. Best of luck in your search for better health! *edited 10/06/16 for clarity.*
