Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
HIV viral load is the main indicator of infection, however CD4 helper cell counts are most predictive of morbidity and mortality.We hypothesized that the consumption of algae could be important in diminishing the risk of HIV infection, and subsequent progression, possibly by enhancing the immune response.
