As I mentioned when I wrote this article about how to treat Long Covid (LC), I would add newer studies adding further information on combating LC as they become available. In that line of thinking, one of the most common Covid-19 and LC symptoms is Anosmia or the loss of smell. In this new study (Nov, 2022), it is shown that the common citrus fruit derived supplement, Hesperidin, reduced Covid-19 and LC symptoms, including anosmia :
Here is a relevant quote from the study :
' During the third wave of the COVID-19 pandemic, only 30% of initially symptomatic nonhospitalized and nonvaccinated subjects were asymptomatic about 18 days after symptom onset. Anosmia affected 50% of subjects and was the most frequently persisting symptom in 30%. Hesperidin therapy is safe and may help reduce a composite of selected COVID-19 symptoms, including fever, cough, shortness of breath, and anosmia. Further trials with this agent are encouraged. This research has previously been published as a preprint . '
