Polychitosamine, a derivative of chitosan, is a modified polysaccharide derived from the shells of crustaceans. Chitosan and its derivatives have been studied as dietary fibers with potential lipid-lowering properties. The proposed mechanism is that chitosan binds to dietary fats and cholesterol in the gastrointestinal tract, reducing their absorption and thereby lowering blood lipid levels, including triglycerides. Some small randomized controlled trials and animal studies have shown modest reductions in total cholesterol and LDL cholesterol with chitosan supplementation, but data specifically targeting triglycerides is less robust. Meta-analyses suggest that chitosan may have a mild effect on triglyceride levels, but the effect size is small and often not clinically significant. The quality of evidence is generally low to moderate, with studies often limited by small sample sizes, short durations, and variable dosing regimens.

While chitosan-based products are marketed for weight loss and lipid management, major health organizations do not currently endorse their use for hypertriglyceridemia due to inconsistent and insufficient evidence. Reported adverse effects are generally mild (e.g., gastrointestinal upset). In summary, there is some scientific evidence that polychitosamine and related compounds may modestly lower triglycerides, but the overall strength of evidence is weak and further high-quality research is needed to confirm these effects and establish clinical relevance.
