Modified Citrus Pectin is OTC and is, I guess, a relatively weak Galectin-3 Inhibitor. More powerful Galectin-3 Inhibitors are in development.

Evidence Summary
Have the potential to reduce organ fibrosis and protect against neuroinflammation. Clinically tested inhibitors show good safety but modest efficacy. More potent and specific inhibitors are in development.
Neuroprotective Benefit: Elevated galectin-3 is associated with cognitive decline. Galectin-3 inhibition may reduce pathological microglial neuroinflammation. Novel BBB penetrant inhibitors may need to be developed.
Aging and related health concerns: Elevated serum galectin-3 is a prognostic marker for reduced heart function, fibrotic disease, poor prognosis, and mortality. Inhibitors show potential benefits for fibrotic diseases in early clinical trials.
Safety: Good safety profile in clinical trials, but currently available inhibitors are relatively weak and non-specific. Many novel galectin-3 inhibitors are currently in preclinical development.
