SLC6A6
SLC6A6 taurine transporter — the molecular target that 1 compounds in the wiki act on.
In one line: The doorway that carries taurine into your heart and muscle cells.
SLC6A6 moves the amino acid taurine into cells, where it stabilises the heart and muscles, helps manage calcium, and acts as an antioxidant. Taurine levels fall with age, and in a major animal study, topping it up extended healthy lifespan.
It's cheap, safe, and increasingly interesting for both endurance and longevity — this doorway is simply how it gets where it's needed.
