N-Acetyl L-Cysteine is a bioactive form of the amino acid cysteine
N-Acetyl L-Cysteine, known by the abbreviation NAC, is a bioactive form of the amino acid cysteine, one of the building blocks of proteins. Cysteine is one of the semi-essential amino acids, which the body can make only if it has enough of the amino acids serine and methionine. However, when the body lacks these amino acids, it is a good idea to supplement them regularly.
Other benefits include the fact that N-acetyl L-cysteine can be converted to cysteine in the body and also help with reaching its optimal levels. Like cysteine, its NAC form is a precursor to glutathione.

Most reviewers speak very positively about NAC for immune and liver support, antioxidant and anti inflammatory effects, and a noticeable boost in well being, energy, and mental clarity. Many also report it suits daily routines and is easy to take, with few to no digestive issues for them. The main recurring drawback is a reduced NAC amount per capsule versus earlier batches or versions.

Until recently, the formula was 500 mg per capsule. It never even occurred to me to check whether anything has changed. Now it is 150 mg, which is—how should I put it—for pine extract: because the Nac benefits start at 600 mg, so realistically it makes sense to take at least 4 tablets; in my case, even more. In every second product review, I read that the quality has gone downhill, and this time it was confirmed for me. Last time I am ordering from Gymbeam. It has been overhyped for a long time and nothing special—at least not anymore. Hopefully, several customers will finally open their eyes.

It is good to have this product in the house. It has a multitude of beneficial effects. I found Gymbeam while actually looking for NAC, and I sincerely hope it won’t disappear from here. It is affordable, has low toxicity (recommended after a drinking binge), has been approved by the FDA for many years, and it seems to have therapeutic effects against COVID because it suppresses the “cytokine storm,” protects T cells, and reduces inflammation and cell damage caused by the virus.
