Assessment of the ability of seaweed extracts to protect against hydrogen peroxide and tert-butyl hydroperoxide induced cellular damage in Caco-2 cells

► Seaweed extracts reduced hydrogen peroxide-induced cell DNA damage. ► Seaweed extracts did not protect against tert-BOOH-induced cell DNA damage. ► Seaweed extracts reduced H2O2-induced superoxide dismutase depletion. ► Seaweed extracts protected against tert-BOOH mediated depletion in SOD activity.
