I take both glycine/NAC because they have both individual roles which I dimly understand and because together they create —in just the right amounts—glutathion which is a big antioxident. I also take TMG—originally because I was takin NMN or B3 or niacinimide...and its said that these supplements deplete TMG. But I have cycled off all of them for now. And I still take TMG. Now for no reason except habit. It would be nice if TMG did reduce or prevent arterial plaques. But its not clear that TMG is an analog for the peptide mentioned in this article.
It would seem the new tripeptide used leucine, but the paper itself doesn’t validate that.
