n-acetyl cysteine verses l-acetyl cysteine?
 

Hi, I am trying to wade through the wealth of information on here for supplements and PN. I started with this supplement, and of course the store carries the L-acetyl, but my notes say N=acetyl.

Now I can't find out exactly *where* I read that :p, as I spent at least a couple hours doing so.

Could someone tell me what the difference is and if it matters.

Heck, could someone just give me a list of the supplements to try,
dosages, and brands. Just kidding....sort of!

There are way too many brands to choose from!

And not all brands are created equal.

Thanks,
Sunrise

N-acetyl Cysteine has a nitrogen on the molecule

L-acetyl cysteine has not.

NAC is how it is typically abbreviated. NAC is a precursor given to improve glutathione synthesis in the body. You may see NAC as N-acetyl-l-cysteine which is its chemical name. Not all places put the -L- in there when the N is there.

The L- when used with amino acids denotes its stereo left or right handedness. Biological human systems require L. Some places don't always put the L in there, as it is assumed these days to be that form which is the only active form.

Don't confuse this with acetyl-l- carnitine This is a different thing all together.

AHHHH! Would you believe that is exactly what I did? They are selling Lipoic Acid with L-carnitine and I almost bought it!
Though this combo does sound like it makes sense, still, that is not what I was intending to purchase.
Thank you,
