N-acety l cysteine benefits?

N-acety l cysteine benefits?

I’ve been taking NAC as part of a diet I’m doing, and to reduce mucus build up so my singing voice is clearer. (Thanks, Hobby, for bringing up NAC in that Fat Flush Diet thread. I rediscovered I had a bottle of it in the cabinet.)

But I just stumbled on this research this morning. It sounds like NAC might have effects similar to arginine. It could have benefits for ED, PE, and general penis health.…ay_01/news4.cfm

N-acetylcysteine Improves Blood Vessels

N-acetylcysteine (NAC), a relative newcomer to the supplement scene, might be recommended for atherosclerotic patients in light of new research conducted at the National Heart, Lung and Blood Institute, one of the National Institutes of Health in Bethesda, Md.

Researchers studied 16 patients whose average age was 50; nine were men. Seven of the patients had coronary atherosclerosis. Nine did not but were undergoing diagnostic cardiac catheterization for other reasons. All patients had coronary angiography performed after coronary artery blood-flow velocity was measured. The researchers determined coronary vascular resistance and blood flow from blood flow velocity, diameter, and arterial pressure. By testing both before and after the artery was infused with NAC, the researchers determined how the blood vessel responded to acetylcholine, nitroglycerine, and other compounds that produce vascular dilation.

In both normal and atherosclerotic heart vessels, NAC improved the ability of the blood vessels to relax, and increased the effectiveness of acetylcholine, which works by relaxing the lining, or endothelium, of blood vessels. NAC did not dilate blood vessels by itself or increase the response to substances such as nitroglycerine, which cause vasodilation by means other than endothelial response.

Researchers suspect this is because NAC enhances the bioavailability of the relaxing substance nitric oxide, but because nitric oxide has a short half-life and cannot be measured by current methodology, they were unable to determine this directly. In addition, NAC may act as an antioxidant that protects nitric oxide destruction. The authors suggest NAC may be beneficial in treating acute and chronic atherosclerotic manifestations.

I haven’t noticed any effects similar to any NO product. Did they happen to mention a dose? I know that at over 2g/day it becomes a pro-oxidant, a scenario we want to avoid. NAC is also good for detoxing the liver and good anti-oxidant. What dose are you taking for the mucous reduction?

I take one 500 mg tab twice a day of this product:

I saw a web page this morning that had the various recommended doses for various things, but I can’t find it now.

I haven’t noticed any effects similar to any NO product

Does that mean you feel effects from some NO products you have tried?

I have read some research that NAC can also reduce blood levels of
lipoprotein (a), an atherogenic lipoprotein.
