Description

N-acetyl cysteine (NAC) is a stable form of the non-essential amino acid cysteine. It is a sulfur-containing amino acid that acts as a stabilizer for the formation of protein structures, and promotes the formation of glutathione. Glutathione is a powerful free radical scavenging compound that also helps to maintain normal, balanced immune system function. In addition, NAC can help to support healthy brain and neuronal tissues. Natural color variation may occur in this product.

    • Taken for Alzheimer’s
Size: 120 Count (Pack of 1)
My spouse has Alzheimer’s disease and has been in various drug trials at a well respected Houston hospital. In 2020, the first drug trial we participated in used a combination of NAC and Glycine at very high doses. (100mg each per kilo of body weight). This combination makes Glutathione, and the trial was to determine any positive effects of high doses of the two drugs in combination, on Alzheimer’s. The trial duration was for 6 months, mainly to test for tolerance, and there were no adverse effects on us. I understand that this trial is still ongoing. The main points I want to share are: The trial used very high doses of both drugs for Alzheimer’s. I wouldn’t suggest doing this without a physician’s approval and oversight. The drug trial physicians could not find a pure enough formulation of either drug commercially, so had to formulate their own, so be sure that you trust your source. The strong smell of NAC is a characteristic of the drug, and the stronger the purer. This is the sign of purity. The ones in the drug trial had a very strong odor. To ensure the safety and quality of any supplement, look for an independent third-party seal on the label, such as U.S. Pharmacopeia, NSF International, GMP or ConsumerLab. I think it’s noteworthy that the study used the two supplements separately, but taken at the same time, instead of a Glutathione pill. While our portion of the trial is over, we have continued to take both drugs together at the 1gm of each twice per day, and while it’s impossible to determine the effectiveness of these two drugs when combined, we are determined to continue the process. ... show more

    • Not sure
Size: 120 Count (Pack of 1)
Figured if this helped MacAfee stay alive running on pure drugs and borderline insanity in a jungle, that it might help keep me going. My life is tame however, and I'm still alive, so it could be working. Would not notice if this went missing from my supplement routine, take that for what its worth.

    • Work, but smells horrid
Size: 120 Count (Pack of 1)
This definitely helps me from picking my cuticles, something I do when my anxiety is really bad. The pills really help, but they smell and taste horrible!!
