GCLC

In one line: The enzyme that builds glutathione, your body's master antioxidant.

GCLC is the key enzyme that assembles glutathione — the most important antioxidant your cells make, and the liver's main tool for neutralising toxins. Glutathione is like your cells' rust-protection: it mops up the damaging molecules that ageing, pollution, and hard training generate.

The catch is that building it needs a specific raw material (the amino acid cysteine) that often runs short. That's why NAC — which supplies exactly that raw material — restocks glutathione so effectively, and why it's the hospital antidote for paracetamol overdose (which floods the liver and drains glutathione).

More raw material in, more master antioxidant out.
