Originally bought 5 years ago after reading article that Taurine and NAC may be effective in treatment for lung damage. After a two week respiratory infection, I am so glad I had this to help clear my lungs.

always use when sick

Yeah the smell is bad and taste is not good either but mixing it in strong tea makes it OK. I use it whenever under stress and if I feel like I might get sick, I take several doses a day. Seems to work as I had several times I felt I might get sick, took a lot of cystine and was OK the next day.

Also useful to combat COVID-19

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7649937/ The novel coronavirus disease (COVID-19) is caused by a virus (SARS-Cov-2) and is known for inducing multisystem organ dysfunction associated with significant morbidity and mortality. Current therapeutic strategies for COVID-19 have failed to effectively reduce mortality rate, especially for elderly patients. A newly developed vaccine against SARS-Cov-2 has been reported to induce the production of neutralizing antibodies in young volunteers. However, the vaccine has shown limited benefit in the elderly, suggesting an age-dependent immune response. As a result, exploring new applications of existing medications could potentially provide valuable treatments for COVID-19. N-acetylcysteine (NAC) has been used in clinical practice to treat critically ill septic patients, and more recently for COVID-19 patients. NAC has antioxidant, anti-inflammatory and immune-modulating characteristics that may prove beneficial in the treatment and prevention of SARS-Cov-2. This review offers a thorough analysis of NAC and discusses its potential use for treatment of COVID-19.

Tart but healthy

This is something that will do you good, best to read up on the benefits as there are many. I'll use it with effervescent vitamin c to help with the taste as it is very sharp on the tongue.
