TRPM6
TRPM6 magnesium transporter — the molecular target that 1 compounds in the wiki act on.
In one line: The doorway that carries magnesium into your body.
TRPM6 is a transporter that absorbs magnesium — a mineral your body uses in over 300 reactions, including making energy, calming the nervous system, and quality sleep. Roughly half of people don't get enough, and athletes lose it in sweat.
Topping up magnesium (especially the glycinate form at night) reliably improves sleep and eases muscle cramps — this doorway is simply how it gets in.
