I wanted to try NAC a couple of months back for my lungs. But, i read an article that says NAC (and even vitamin c) may affect absorption of some antibiotics. Since I am taking antibiotics and I want to get the maximum potency of the antibiotics, I did not push through with NAC.

Somebody read similar idea?

Not before now. I've only read a couple of articles, but it appears it depends on the antibiotic; NAC can help some antibiotics and hinder others.

I also came across this interesting one about antibiotics damaging mitochondria.

The Downside of Antibiotics?

Dr Smith and Stacy,
I checked at iherb and the weird thing was/is there were reviewers saying the Country Life NAC wasn't vegetarian, but much worse, one said it was made from Duck Feathers. How do we know where the NAC comes from and is vegetarian is better ? I have no idea what this reviewer is talking about, but it gave me pause.
Pure Encapsulation makes one that is 900. Don't know much about this company...but heard it was good. Also heard ideally, NAC should be taken two Times a day. Any thoughts?

Holy Duck Feathers!!!!!

What the heck?????????????

NAC is made from l-cysteine which comes from.....

This rather sheds light on the allergic component of side effects, as there may be residual substances left behind during manufacture. The China connection is very disturbing in an of itself, IMO.

Ok, this is disgusting. Nothing can be healthy about duck feathers and human hair.

I am done with this supplement.

But man, it really did make the last few nights of sleeping just dreams.

so long NAC.

You could always get a Vegan one? As described in the second link. I suspect you'd have to call the company up to see where they get the NAC from. Most of what I see on sites today about ingredients do not address the NAC itself but only the capsule (vegetarian), and fillers.

Many things we use today come from icky sources. That is just the way it is now. L-cysteine is a sulfur containing amino acid and that makes manufacture difficult. Has to come from animal sources. Lanolin is also rather icky IMO.

After all the natural thyroid products come from pigs, too.

Me either. How do we know who the blazes "Reviewer3340759" is, what their motives are, whether the information is accurate, or... don't get the skeptic in me started. I don't know, but when I see something like this without credible corroboration, I can't help but think of the old joke, "It must be true—I read it on the Internet!"

(A few mouse clicks later...)

As it turns out, there may be some truth in this, but IMO it's not a matter of chemistry—the molecule is the same regardless of the source—but one of lifestyle choice, and I am not a vegetarian. I thought about throwing a straw man into it and ask, "If it's made from human hair, does that make it cannibalistic," but....

Don't know. The directions on my bottle say take one per day unless directed otherwise by a healthcare professional. I would think if it were better taken twice daily that at least one of these mfrs would make smaller dosage capsules. That would behoove them because they could likely charge more for smaller ones as is the practice with most other supplements.

I recall something else that I can't find or remember clearly, but I did find this:

According to the link I provided from the Vegan source... non-human non animal sourced NAC will cost 2 to 3 times MORE and therefore the product price would be much higher.

Keep in mind people sleep with down products and feather pillows. Those feathers are cleaned before use, but with time break down and particles escape thru the fabric and you breathe them in and they can get in your eyes too. I can't have any feather products in my bed as my eyes swell shut and I can't breathe. No feather linens in our house!
