TET2
TET2 — the molecular target that 1 compounds in the wiki act on.
In one line: An enzyme that helps "reset" the chemical tags on your DNA that drift with age.
TET2 helps manage the chemical tags sitting on your DNA that switch genes on and off — a pattern that drifts as you age (part of the "epigenetic clock"). The supplement Ca-AKG feeds enzymes like this, and a small human study suggested it lowered measures of biological age.
Think of it as helping tidy up the DNA's control settings, which get messy over the years. Promising, early.
