Precautions and Contraindications

Patients with a shellfish allergy should use extreme caution in taking chitosan supplements, as many are derived from shellfish products. Chitosan products may be contaminated with heavy metals, such as lead, mercury, iron, and copper; therefore, chitosan should be avoided in children, pregnant patients, and nursing mothers.[8]
