Taking chitosan supplements for 24 weeks may lead to a tiny weight loss compared to a placebo, but this difference is too small to be meaningful for health.
Chitosan didn't affect other health measures like body fat, blood pressure, or quality of life compared to a placebo.
Chitosan might cause small changes in cholesterol and blood sugar levels, but the study didn't say if they went up or down.
Chitosan doesn't lead to meaningful weight loss in overweight or obese adults over 24 weeks.
Peptides marketed for fat loss often lack robust human evidence, relying instead on animal data or short-term biomarkers without long-term clinical validation.
