N-acetylcysteine also known as Acetylcysteine or N-acetyl-L-cysteine (NAC) increases levels of Glutathione (GSH), the most common antioxidant in the body. Taking GSH directly is costly and inefficient, NAC is a more efficient and economical means delivering GSH to cells.[1] NAC is a pro-drug for l-cysteine which enables cells to synthesise Glutathione providing antioxidant benefits.[2]

Evidence[edit]

In a presentation to the 2016 IACFS/ME conference Dr Dikoma Shungu of Cornell University gave a presentation on a trial of NAC in ME/CFS patients. [3] Previously his team had found a 36% deficit of the tissue anti-oxidant occipital cortex glutathione (GSH) in the cortical areas of the brains ofME/CFS patients.[4]

The trial supplemented patients with 1800g daily of GSH precursor n-acetylcysteine for 4 weeks and looked at levels of GSH. The study found that GSH had increased in patients and that symptoms were significantly reduced.

Clinical use[edit]

No official use for ME/CFS currently.
