Long-time readers know that my “go-to” sources for natural medicines (herbs, vitamins, and supplements) are ConsumerLab.com and Natural Medicines(TM). ConsumerLab has posted about coronavirus and NAC (N-acetyl cysteine):
NAC (N-acetyl cysteine) is a synthetically modified form of the amino acid cysteine (cysteine occurs naturally in foods, whereas NAC does not).
In the body, NAC is converted to the antioxidant glutathione. There is very preliminary evidence that NAC may improve certain blood markers of immune system health but there is not sufficient evidence to suggest that NAC supplementation improves the immune system to the extent that it will reduce the occurrence of illness, nor prevent coronavirus infection.
A clinical study using 600 mg of NAC taken twice daily during flu season found that it did not prevent infection but fewer infected people were symptomatic.
Evidence is weak for its purported ability to thin mucus during infections like colds.
There is no evidence that NAC will be of any help with the novel coronavirus.
ConsumerLab.com has tested and reviewed a variety of NAC supplements on the market and it has published its Top Pick in its NAC Supplements Review, which contains additional information about using NAC, its benefits, dosing, and potential side effects.
Of course, the most important thing you can do to avoid infection with coronavirus is to prevent exposure by following the latest recommendations of the CDC and World Health Organization and take steps to stay healthy, including getting adequate sleep, keeping up with your daily exercise, and eating a healthy nutritious diet.
