Modified citrus pectin

Tier 3 — weak evidence · Heavy metals · Cancer adjunct · Immunity

A modified form of citrus fibre that is small enough to enter the bloodstream and may help remove heavy metals. A handful of human studies show it reduces urinary excretion of lead and arsenic, suggesting it mobilises heavy metals. Early cancer research shows it may slow certain cancer progression by blocking galectin-3, but trials are small. Generally very safe and well tolerated with no serious side effects reported.

Dose: 5–15 g/day in divided doses; limited but growing evidence for heavy metal chelation
