How does activated charcoal reduce toxin absorption?

Explanation:
Activated charcoal reduces toxin absorption by adsorbing toxins in the GI tract. Its porous surface binds many substances, keeping them in the gut lumen so they cannot cross the intestinal wall into the bloodstream. Because the toxins stay bound and are not metabolized or filtered away, they are eliminated in the stool, reducing systemic exposure. It doesn’t break toxins down in stomach acid or neutralize them in the blood; its effect is local to the GI tract and depends on using it for appropriate ingestions within a suitable time window.
