Ubiquinone (CoQ-10, CoQ10, MytoQ) might have strong prophylactic and/or therapeutic activity against COVID-19. People taking Ubiquinone were found to have 5.7x lower rates of hospitalization with COVID-19 in Israel. The sample was small, though, and the methodology did not allow to check for confounding medications.
(Israel et al., 2021) is a recently published reverse observational study. It attempted to detect users of which drugs (among those that are available Israel) are not getting hospitalized with COVID-19. The cohort of individuals hospitalized with COVID-19 was matched with a larger cohort from the general population. Average age was 65 in each cohort.
Surprisingly, nutritional supplement Ubiquinone came on top. People taking Ubiquinone had 5.7x lower rates of hospitalization with COVID-19. The downside of it is a small sample size – only 6 individuals taking Ubiquinone were hospitalized with COVID-19. (Israel et al., 2021) also provided an explanation:
“It is remarkable that these three drugs [Rosuvastatin, Ezetimibe, and Ubiquinone] act on the cholesterol and ubiquinone synthesis pathways, which both stem from the mevalonate pathway”
There is very little literature about Ubiquinone and COVID-19. Only one trial (Aarhus University Hospital, 2021) Coenzyme Q10 as Treatment for Long Term COVID-19 (QVID) could be identified. Theis not much literature on the topic and it suggests also other possible mechanisms of action. It is listed here without comments.
(Ouyang and Gong, 2020) Mitochondrial-targeted ubiquinone: A potential treatment for COVID-19
“Mitochondrial-targeted ubiquinone (MitoQ), a mitochondrial-targeted antioxidant, shows beneficial effects on various diseases through improving mitochondrial dysfunction. We hypothesize that MitoQ could act as a potential treatment in COVID-19. MitoQ may alleviate cytokine storm and restore the function of exhausted T cells in COVID-19 patients through improving mitochondrial dysfunction.”
