Dosage and Adverse Effects

Generally, people taking chitosan for cholesterol reduction use between 1000 and 1200 mg twice daily, although dosages in some studies have been as high as 6 g/day. Chitosan for weight management has been used in dosages ranging from 1 to 5 g/day, taken in divided doses.

The most commonly reported adverse effects of chitosan are gastrointestinal problems, such as nausea, diarrhea, and constipation.[7,8] These effects are generally not reported as being severe enough to cause discontinuation of chitosan use.
