Modified Citrus Pectin / MCP

Citrus sinensis (modified fraction)

Anti-metastaticmoderate evidence

Modified Citrus Pectin (MCP) is a specially processed citrus fibre that inhibits galectin-3 — a protein cancer cells use to stick to vessel walls and form metastases. Clinical studies show MCP significantly reduces PSA doubling time in prostate cancer. It also binds heavy metals and environmental toxins. MCP is one of the few supplements with direct anti-metastasis evidence in human trials.

Cautions & Interactions

May cause initial digestive discomfort — start low
May interact with chemotherapy timing — take separately
Ensure product is genuinely 'modified' (low molecular weight) — regular pectin does not work the same way
Expensive — prioritise if prostate cancer or high metastasis risk
