Definitely shows promise

Posted by iHerb Customer on Oct 30, 2009 | Verified Purchase

I have/had a 30% hearing loss from family genetic predisposition. I've been taking this supplement for 3-4 months now and I believe there has been definite improvement. Maybe a 10%-15% reduction. I've stopped using my hearing aids and though I still have trouble hearing I'm picking up much more conversation than I did in the past. I'm 54 but I think this is definitely worth a try. This substance was supposedly tested by the US Navy to help prevent hearing loss onboard ships but it has also helped me.

Thanks for your feedback!

Too early to tell.

I started taking 1 x 1000mg a day to see if it had any of the mucolytic affects that my research advised it might. To date I can't say that I've noticed any perceivable difference but I guess the results will be apparent during my next lung function test with my respiratory specialist. I haven't experienced any of the usual side effects such as overly smelly flatulence or feces. But then again both my flatulence and feces didn't have a particularly pleasant bouquet in the first place...any change might have been an improvement. One thing I'd recommend is to look at getting some vitamin C as well. This isn't something that iHerb or the Source Naturals instructions advise but a few minutes on google will show you that high dosages of NAC have side effects that are minimised by taking at least a 2:1 ratio of vitamin C to NAC. With a 1000mg dose of NAC you'd be taking 2000mg of vitamin C which is right on the border of the safe recommended daily intake for vitamin C before the laxative effects kick in and other long term high dosage complications such as kidney stones can occur. My 3 star rating at this stage is really just based on the good service I received from Source Naturals rather than the product itself as I haven't had a long enough exposure to NAC to make any firm decisions on whether it's been beneficial or not. Definitely recommend iHerb. The product was on my door step within 14 days...and I live in the middle of nowhere even by New Zealand standards.

Powerful antioxidant in a larger dose

Posted by iHerb Customer on Dec 05, 2008 | Verified Purchase

I have been taking NAC for months now, and I appreciate the larger 1 gram size, also need to up my vitamin c dosage to 3 grams with this monster, otherwise it can cause more bad than good. Strong sulfur odor lets me know it means business.

Thanks for your feedback!

Excellent pill

I have used this product for a year now and my friends had told me a difference in my skin. Whiter and fairer. It took 3 months before you start to see results. 5 star rate I purchased this product from IHerb,cheaper and effective to me.The one I purchased from GNC doesn't work at all besides they got the 50 mg stock only compared to 1000 mg dose from iHerb.

N-Acetyl Cysteine by Source Naturals

I like Source Naturals in general. I learned about them through Dr. David Perlmutter's book The Better Brain. I like this particular product becasue it is so highly concentrated.

Thanks for your feedback!

May help those with depression

Recommended by my Dr for depression. Apparently latest research shows it helps repair the brain even better than fish tablets.. Have been feeling great with the antioxidant support.

Thanks for your feedback!

Excellen t Product

Really helps my Bi-polar a lot. Great Product. Postage very slow using International Airmail to Australia it took 2 1/2 months. This is not Iherb's fault though.

Source Naturals, N-Acetyl Cysteine

Posted by iHerb Customer on May 16, 2008 | Verified Purchase

I heard that this was a good way to combat environmental pollutions ie. Chemtrails and I have not been sick since. I believe N-Acetyl Cysteine might a factor.

Thanks for your feedback!

Wonderful Supplement

Posted by iHerb Customer on May 25, 2011 | Verified Purchase

My son had suffered from six months of bronchitis every winter and spring for 3 years. I decided once and for all to get rid of it. I gave him one of these twice a day along with vitamin C and Elderberry extract. Within 3 days his cough was gone, and he hasn't had it since (this was 3 years ago). If it comes back, I know what to do. Now my husband takes it for his bipolar and depression. I think I will take it too--it seems like it is wonderful for so many things that I can't see how I could go wrong!

Tried Source Natural's after Google'ing brands that pushed out quality multi vitamins. Source Naturals was a brand that was ranked higher than Jarrow's, but I think quality and potency differs for specific supplements. I found the Jarrow's Sustained NAC a better formula than Source Naturals.
