Yes, on topic- N-acetyl cysteine does not, which is helpful for this entire thread.
My point was missed- researching should never be assumed. Carnosine, a peptide made up of proteins suppresses mTOR. Beyond, there’s a dose dependant effect. Leucine, a SIRT1 activator has an addictive effect with metformin and does not activate mTOR1 at specified dosing regime. It has application to improve efficacy of metformin. It’s not as simple as putting leucine in a box in the context of elevated mTOR1 = deleterious.
Besides, amino acids do not activate mTOR1 in the presence rapamycin.
And what perceived results can you report? I ask as I too have been taking it (10 NAC 8 glycine) for a year now per Dr. Green’s recommendation. I may (or may not) have experienced a small endurance benefit. I most definitely have not experienced more than a small fraction of the benefits that the participants did in the study that DR. Green refers to.
I only started using Morgan Levine about six months ago, but, no, no particularly notable results - but I having been doing most things “right” for a few years all the time, ie no bad carbs, no bad fats, moderate protein, low body fat, 4 hours zone 2 cardio per week, 2 hours quality strength training per week, etc. There might not be potential for great change.
There’s also a product called glyteine sold under the brand name Continual-G that’s promoted as a way to boost glutathione levels. (Link)
And then there’s a compound called NACET which is a derivative of N-AcetylCysteine that is believed to be more bioavailable and more efficiently boosts glutathione. It has recently been introduced as a supplement product.
