1. A method for reducing the level of the surface antigen of hepatitis B virus (HBsAg) detectable in a subject suffering from chronic hepatitis B virus (HBV) infection in a subject in need thereof, comprising the step of administering to the subject an effective amount of a cyanobacterial biomass, and the step of administering an effective amount of an antiviral agent, wherein the cyanobacterial biomass is derived from Arthrospira maxima and the cyanobacterial biomass is administered orally at an effective amount of 1 to 20 grams per day for at least three months to result in a decrease of HBsAg level by at least 30%.
