The Role of Resistant Starch in COVID-19 Infection

  • Study HIC#:2000027887
  • Last Updated:06/02/2020

This study is a multicenter randomized trial to evaluate the efficacy of administering a dietary supplement containing resistant starch to non-hospitalized COVID-19 positive subjects, The intervention will begin as soon as possible after subjects test positive for COVID-19 and continue for 14 days. Investigators hypothesize that short-term administration of a dietary supplement containing resistant starch has the potential to reduce rates of hospitalization and improve time to clinical recovery and symptoms in non-hospitalized COVID-19 positive patients.
