Great product

This has worked so well with clearing out mucus from my lungs. Just as a warning, it works TOO good when taking consistently! You will have a lot of phlegm but I think it was worth the purchase. Read more

Does the job, includes selenium - smart move

Look, I'm not going to pretend NAC is some miracle supplement that changed my life overnight. Been taking this daily for about six weeks, and honestly? It just works. No drama, no fuss. The capsules go down easy, my stomach doesn't hate me for it, and here's the kicker - they threw in selenium. Why does that matter? Because NAC can actually deplete your selenium over time, and most people don't know that. So NOW Foods basically did your homework for you. That's the kind of attention to detail I appreciate. Fair warning: when you crack open the bottle, you'll get a whiff of that signature sulfur smell. It's not pleasant, but it's also not a deal-breaker. The capsules themselves don't taste like anything, so once you get past the initial "what died in here" moment, you're fine. Bottom line: if you're looking for a straightforward NAC supplement that doesn't require you to buy three other things to make it work properly, this is it. Good price, solid brand, does what it says on the tin. Skip it if you're expecting some kind of immediate transformation or if sulfur smells make you queasy. Read more

A Solid Choice, With One Small Quirk

I've been taking NAC for general wellness and antioxidant support for the better part of a year, and I decided to try this NOW brand bottle because the value is just fantastic for a 250-count. I've always trusted NOW for quality, and this product is no exception. The capsules are a standard size, easy enough to swallow, and have no aftertaste, which I appreciate. I genuinely feel they contribute to my overall respiratory health, especially during seasonal changes. The only reason I'm docking one star is the issue with speckling. After having the bottle for a month or two, I noticed some of the capsules started to get small, dark spots on them. After a bit of reading, it seems this is just oxidation and isn't harmful, but it can be a little off-putting to see your supplements changing color. It hasn't stopped me from taking them, but it's something to be aware of. I'll likely buy them again, but I might try storing them in the fridge next time to see if it helps. Read more

Supercharge your liver and say "goodbye" to hangovers...

*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.* Read more
