Er wordt veel onderzoek gedaan naar mogelijke positieve effecten van vitaminen, mineralen, kruiden, aminozuren, vetzuren, probiotica en overige voedingsstoffen in relatie tot het immuunsysteem. De laatste tijd is dit onderzoek vanzelfsprekend gericht op de relatie hiervan tot het coronavirus. Een gezonde leefstijl is natuurlijk belangrijk en ondersteuning van je gezondheid in de vorm van specifieke supplementen kan daar een bijdrage aan leveren.
CellCare Academy houdt de internationale wetenschappelijke literatuur bij op dit gebied. Recent hebben we webinars gegeven over SARS-CoV-2 en Therapeutische interventies bij SARS-CoV-2.
De volgende studie willen we graag delen. Het betreft een observationeel onderzoek onder ruim 445.000 appgebruikers uit 3 landen. Dit geeft onder andere informatie over zelf gerapporteerd gebruik van voedingssupplementen.

Modest effects of dietary supplements during the COVID-19 pandemic: insights from 445 850 users of the COVID-19 Symptom Study app
Abstract:
Objectives Dietary supplements may ameliorate SARS-CoV-2 infection, although scientific evidence to support such a role is lacking. We investigated whether users of the COVID-19 Symptom Study app who regularly took dietary supplements were less likely to test positive for SARS-CoV-2 infection.
Design App-based community survey.
Setting 445.850 subscribers of an app that was launched to enable self-reported information related to SARS-CoV-2 infection for use in the general population in the UK (n=372.720), the USA (n=45 757) and Sweden (n=27.373).
Main exposure Self-reported regular dietary supplement usage (constant use during previous 3 months) in the first waves of the pandemic up to 31 July 2020.
Main outcome measures SARS-CoV-2 infection confirmed by viral RNA reverse transcriptase PCR test or serology test before 31 July 2020.
Results In 372.720 UK participants (175.652 supplement users and 197 068 non-users), those taking probiotics, omega-3 fatty acids, multivitamins or vitamin D had a lower risk of SARS-CoV-2 infection by:
respectively, after adjusting for potential confounders. No effect was observed for those taking vitamin C, zinc or garlic supplements. On stratification by sex, age and body mass index (BMI), the protective associations in individuals taking probiotics, omega-3 fatty acids, multivitamins and vitamin D were observed in females across all ages and BMI groups, but were not seen in men. The same overall pattern of association was observed in both the US and Swedish cohorts.
Conclusion In women, we observed a modest but significant association between use of probiotics, omega-3 fatty acid, multivitamin or vitamin D supplements and lower risk of testing positive for SARS-CoV-2. We found no clear benefits for men nor any effect of vitamin C, garlic or zinc. Randomised controlled trials are required to confirm these observational findings before any therapeutic recommendations can be made.
