Taking this for brightening

Posted by lippyjunky on Mar 14, 2016

Along with Vitamin C. So far I don't see if it's more effective than L-Cysteine. Bought this because of the huge bottle and that NAC is supposed to be the more stable form of cysteine. I don't know, will continue and see.

OK, I guess?

It's difficult to tell i this had any effect. Maybe it worked, maybe it didn't. I've got asthma and somewhat chronic sinus problems, and I didn't notice that much improvement when using NAC from this brand. I've tried different brands like Solgar and felt a better response. It should be the same substance though... Maybe it hasn't noticeably helped me with my lungs, at least yet (3 months), but works possibly better as a detox agent? I'll probably buy Solgar next time to see if there really is a difference.

I don't like that iherb makes you review every single thing in your order. I wanted to add a review for one thing, but the only way iherb will accept that is if I review every single thing from this order. Maybe it's different if you just review from your account, rather than from a link in the email they send for reviews. So I added a 3 star rating because I don't want to show something negative when I didn't want to review this in the first place.

Capsule is a pain

Posted by Reviewer3253087 on Apr 15, 2012

The product in the capsule is fine; the capsule is a pain in the throat. This product capsule often becomes caught in my throat unless I take it with a mouth full of food. If you take it with water, let it soak in your mouth for 1/2 a minute first. NAC really burns in the throat so make sure it goes down the first time.

for bipolar disorder

Posted by Reviewer1864518 on Mar 05, 2012

I bought this product because I had read about some small studies in Australia that showed it might have some efficacy for bipolar disorder. I don't think I have been taking it long enough to say whether it is helpful or not in that regard. I will update when I know more.

Can Breathe with through my nose again.

Posted by Reviewer3356710 on Mar 24, 2011

It seems like I always have at least one side of my nose to where I couldnt breathe through, but after taking the NAC with Vitamin C it cleared that up like within a couple of hours. The only problem is that they make my head feel like of weird. Not sure why they do, but they do. But they definately help to breathe better.
