Mild NAC success story. Anyone else?

Background: Moderate CFS for 3 years post mono. I suspect a lingering EBV infection drives the majority of my symptoms. I take 3 grams of valacyclovir a day to suppress replication. I get very sick with mono-like symptoms and PEM if I miss a dose.


I took NAC for close to 2 months earlier this year (600mg a day.) I noticed I felt a whole lot better within a month or so but wasn't exactly sure it was the NAC helping me because I had a few other supplements in my stack. A few weeks later, I decided to drop all my supplements and see how I felt without them. Stopped NAC, l-lysine, zinc, and monolaurin. I did not drop my 3 grams per day Valacyclovir because it's the only drug I've found that stops my chronic EBV from replicating. I felt horrible again for a little over a month and assumed the combination of supplements I was taking were actually providing some benefit.

That month went by and then I started back on NAC alone and I was back to feeling much better. My lymph nodes weren't as swollen, my inflamed tonsils and sinuses were much better, I had more energy, and my activity threshold for triggering PEM had increased tremendously. I first expected a crash after exerting myself more than usual but it never came. I kept slightly over-exerting myself with short walks and even a quick mini-tennis session that led to no PEM. I was so happy to have a small part of my life back !

These benefits lasted the entire month I was back on NAC. I'm fairly confident I would have crashed hard several times with that much exertion if it weren't for the NAC.

Unfortunately, it's not a perfect fairytale story. A week ago, I came off the NAC again because it makes me pretty apathetic if I take it everyday for too long and I'm back to feeling pretty yucky within a couple days off it. Not completely terrible but noticeably worse. This could be a coincidence but I truly believe NAC helps my CFS. I also started back on L-lysine and it definitely helps with brain fog. No question. These are the only two supplements that have provided some CFS relief. I believe it more than ever that lingering EBV is to blame for a majority of my symptoms. I'll try to adjust my NAC dose so it doesn't make me apathetic while also provided CFS relief.

Here is some research I've found regarding NAC and EBV inflammation.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5724866/

The extra glutathione production from NAC could be the reason it helps me so much. I do I suspect it helps with the inflammation directly related to the EBV but I wouldn't doubt it to be more complex than that.

Has anyone else noticed a strong benefit from NAC?

Nac inhibits the NLRP3 inflammasome pathway and NLRP3 inflammasome activation normally can lead to reactivating Epstein-Barr Virus, while inhibiting NLRP3 efficiently represses EBV reactivation so maybe that is part of why that helped you related to a lingering EBV infection. Hopefully the NIH and other researchers will eventually give more info on the mechanisms of ME/CFS so that drugs can be found, created or other treatments can be more effectively targeted.

NAC has been shown to inhibit the NLRP3 inflammasome pathway (IL1β and IL18) in vitro, and decrease plasma TNF-ɑ in human clinical trials. NAC has been used to replenish glutathione stores and increase the proliferative response of T cells - N-Acetylcysteine (NAC) is an antioxidant and a precursor of the synthesis of glutathione (GSH). https://www.sciencedirect.com/science/article/pii/S0306987720308811 https://pubmed.ncbi.nlm.nih.gov/32504923/

Glutathione Transferase Omega-1 Regulates NLRP3 Inflammasome Activation through NEK7 Deglutathionylation - NLRP3 Inflammasome activation is limited by Exogenous GSH (Glutathione) and augmented in the presence of GSTO1-1 which suggests deglutathionylation as a possible process required for NLRP3 activation. https://www.cell.com/cell-reports/pdf/S2211-1247(19)31127-1.pdf

Added Note: NAC also appeared to be helpful for blood clotting, even in an ADAMTS13 deficient state. N-Acetylcysteine (NAC) was able to reduce the size of large Von Willebrand Factor (VWF) multimers, and inhibits platelet activation and formation of platelet-monocyte complexes. Injection of NAC into ADAMTS13-deficient mice led to the rapid resolution of thrombi and reduced plasma vWF multimers. Some people however it mentioned do have adverse allergic reactions in response to intravenous NAC infusion, and in those specific cases, they only showed concordant and rapid marked INCREASES in factor VIII activity and vWf antigen, rather than decrease, unless they took it with an antihistamine so that is important information for anyone who uses it if they get adverse reactions. https://gut.bmj.com/content/54/4/515

Amazing stuff. Thanks again for sharing your findings. Makes a lot of sense. I plan on really diving into these studies when I have the energy and maybe I'll share some of my findings. Just bought Liposomal Glutathione today to replace NAC so we'll see how that goes. Thanks !

Perhaps someone can also consider looking at trying S-Acetyl L-Glutathione I mentioned here, and can see if NAC vs Glutathione shows any benefit differences.
