Charcoal is effective for ochratoxin but not zearalenone, whereas clay or probiotics may be more effective for zearalenone.

“So, charcoal is really good at certain mycotoxins, like ochratoxin. But charcoal is not very good at zearalenone, which comes from Fusarium. Fusarium is another mold that makes zearalenone. ... But charcoal doesn't work very well at detoxing it. A clay would work better or possibly a probiotic.”
