    I’ve been using 2x NAC (600mg) twice a day for the last 5 years, (80 year old) because of a high speed motorcycle accident (120mph) where every rib left side had double breaks, causing massive scarring to left lung, this strategy has gotten me through 3 genuine Co.vid episodes, also 1 attack last year and 2 this year of Sepsis from a severe kidney infection ( 2 big stones in left kidney) now fighting to save this kidney, Nephrostomy tube fitted. But I totally believe this Is why I’m still here, and the massive boost it gives your immune system.

    Started taking 600mg 11 years ago and then 2x day as suggested for my age (78 now). I have not had any cold or flu since then. Only had the 2 dose J&J vaccine for covid (sorry I was intimidated), never got it though was exposed several times. 2 yrs. ago, finally quit PPI’s, and lungs cleared. The started low carb/keto and IF, lost 75 lbs. Feel pretty good!

    • @ianmontgomery9356 on November 17, 2024 at 11:24 pm

      don’t worry the JJ was not a mRNA vaccine and thus no spike protein problems.

    • @Willy-hs7uu on November 18, 2024 at 1:35 pm

      I used to get 2-3 colds a year, after NAC I have probably only got it twice in 8 years. for boosting immune system even more, zinc + quercetin quercetin acts as an Ionosphore for zinc to enter cells and combat viral replication. zinc is a powerful antiviral but has difficulty entering healthy cells where viruses “program” those cells to replicate the virus.

    • @pen25 on November 19, 2024 at 1:26 pm

      no reason to be sorry for and you were smart. the vaccine helped millions. dont be intimidated now into thinking it was a bad idea. only idiots would believe a single compound like this can heal as much as it can becaue every 10 years there is a new thing that heals all these same things. shark fin was claimed to heal these things.

    • @Willy-hs7uu on November 18, 2024 at 1:24 pm

      That was just more evidence that the main function of the FDA is to protect big pharma profits. ban anything that competes with prescription drugs, ban natural substances that big pharma can make a synthetic patented form of. they are doing this with peptides, example BPC-157 a naturally occurring peptide in our stomachs, that stimulates healing and tissue repair. it will be banned until it can be patented and sold for 2000 % more, like they have done with other peptides already.

      FDA recalls over 1000 substances a year that THEY approved because of dangers and complications, yet want to remove cheap safe effective natural supplements . I have been taking NAC for about 8 years now non stop. I found out about it when it was recommended by our toddlers doctor for his breathing problem (mucus). since I also suffered from that, I took it myself, then did more research on the ingredients within the German made medication, and NAC was the main active ingredient.

      I now combine NAC with Glycine, as they work together to boost glutathione.

      the reason NAC was to be pulled so that big pharma could profit “bigly” from it, was it’s effect on oxidative stress and the inflammation it caused from getting Covid.

      Although today my main reason for NAC is anti aging, it has continued to help prevent getting colds, and breathing problems. it also seems to help with my tinnitus, not directly, some things like Ibuprofen or Tylenol can make my tinnitus worse, NAC clears these out of my system, as a matter of fact, NAC is used as an antidote for tylenol poisoning in hospitals.

    • @jamesfeldman4234 on November 19, 2024 at 7:44 am

      A little background on the attempt to ban NAC. The FDA originally asserted that NAC cannot be sold in supplements because it was first used as a pharmaceutical ingredient in 1963 and therefore is not a legal dietary ingredient. However, this “rationale” was and is bogus. Many pharmaceutical products were first derived from or directly related to natural sources. And just because a firm managed to get a patent on a drug doesn’t mean that a naturally sourced supplement can’t have the same components, ingredients, etc., and can’t be sold.

      I love the information, but his NAC cost to much. You only get 30 pills in a bottle and if you are having to take the recommended dose of 2 pills two times a day, well that bottle will only last 7 1/2 days, so you would have to buy 4 bottle for one month.
