    I’ve seen at least one study in humans using dosages as high as 7.2 grams per day of both Glycine and NAC. I think many people are actually taking far too little, and yet hoping to see the longevity benefits associated with GlyNAC, especially when it has been shown to extend the lifespan of mice by 24%.

      you want minimal effective dose
      and minimal nr of supplements that actually work

      thinking this way you will take many supplements in high doses without any understanding how these alter your body processes and how these doses counter each other

      people take high doses of 1 type of B vitamin or vitamin D or vitamin C or melatonine without any understanding how much they deplete other vitamins and body resources…

      they feel great for 3 months max a year and then they crash for something else

    I was dx with Pustular Psoriasis a decade ago. Palliative care was a cream steroid and to wrap my hands and feet in Saran Wrap every night….in perpetuity. It only took one night to know I wasn’t going to live like that. Long story short, I take NAC and frankincense every day. I have zero symptoms or signs of my rare type psoriasis. The last time I was at a dermatologist for a rash from a plant, she asked me how I knew I had pustular psoriasis bc there was no evidence on my body. I told her I had managed my psoriasis using NAC & frankincense. She said there was no way I ever had it then. I showed her photos of my hands and feet. She was incredulous. Then she told me to stop taking it bc it could possibly make my rash worse…. She’s Pharma trained, so I expected nothing less. I can also vouch for the effects of NAC on the lungs (I have an allergic asthma). I take no pharmaceuticals.
