Many people who get infected with COVID-19 experience persistent post-illness conditions known as long COVID. However, because of the wide range of long COVID symptoms, an effective treatment hasn’t yet been found. However, a clinical trial published in The Lancet Infectious Diseases on Dec. 7, 2023, suggests that an oral gut microbiome formula, SIM01, can effectively alleviate various long COVID symptoms.
Long COVID is marked by symptoms lasting for weeks or even years after contracting COVID-19. It’s estimated that at least 65 million people worldwide suffer from long COVID, and the number of cases continues to rise. Long COVID usually affects the respiratory, gastrointestinal, and neuropsychiatric systems, often accompanied by fatigue.
