What is the recommended dosage for Chitosan?

Fat Binding: 1,500-3,000 mg/day before meals; Cholesterol Support: 1,000-3,000 mg/day

What are the side effects of Chitosan?

Potential side effects include: Constipation, Gas and bloating, Nausea, Allergic reactions in those with shellfish allergy (contraindicated).

What is chitosan and how may it relate to cardiovascular health?

Chitosan is a fiber derived from crustacean shells that may bind dietary fat in the intestine, reducing fat absorption. Some clinical trials suggest modest effects on total and LDL cholesterol. However, a Cochrane review found the effects small and of questionable clinical significance. It is more commonly marketed for weight loss.

What dosage of chitosan has been studied for cardiovascular outcomes?

Clinical trials have used 1–5 grams of chitosan per day, typically taken before meals. Cholesterol-related studies most commonly used 2.4–3 grams daily for 4–24 weeks. Results have been inconsistent across studies, with meta-analyses showing only small effects that may not be clinically meaningful.

What are the potential side effects of chitosan?

Common side effects include constipation, bloating, and indigestion. Chitosan may reduce absorption of fat-soluble vitamins (A, D, E, K) and medications. Individuals with shellfish allergies may react to chitosan, though the allergen is typically in the protein, not the polysaccharide. Long-term safety data is limited.

About

Chitosan is a positively charged polysaccharide derived from crustacean shells that binds bile acids and dietary fat in the intestine. A 2018 Cochrane review of 14 RCTs found a statistically significant but clinically modest reduction in total cholesterol, though its practical clinical significance is debated.

How It Works

A positively charged polysaccharide that electrostatically binds negatively charged bile acids and dietary fat forming insoluble complexes excreted in feces; reduces dietary fat absorption by 1-5%; bile acid sequestration triggers hepatic LDL receptor upregulation similar to bile acid sequestrant drugs.
