Ka 1917, ho ile ha etsoa phuputso ea baeloji ho supa boleng ba lijo tse sa sebetseng.
Ka 1930 Albert Szent-Gyorgyi o pakile seo hyaluronic acid, eo a e ntshitseng litulong tsa likolobe tsa adrenal ka 1928, e na le sebopeho se ts'oanang le vithamine C, eo a khonneng ho e fumana ka bongata ho tsoa pelepele ea tšepe.
Ka 1932, lipatlisisong tsa bona tse ikemetseng, Heworth le King ba ile ba theha lik'hemik'hale tsa vithamine C.
