Best supplements and nutraceuticals for COVID-19: the scientific research

Any treatment for COVID-19 is not intended to replace vaccines and other measures e.g. social distancing etc.


However, COVID-19 is a problem globally. In our opinion, all treatments that are

  • practical
  • safe
  • effective

should be used. No treatment is 100% and effective for all variants.


Since the outbreak of COVID-19, we’ve heard a lot about nutrition, immunity and COVID-19...most of it based on theory, not actual scientific evidence.


 Nutritional supplementation for COVID-19 is an attractive option due to:

  • wide availability
  • low cost, particularly in developing nations
  • relatively safe


However, initially there was no data regarding nutrition, nutrition components and supplements in COVID-19. Luckily scientific data from studies with COVID-19 patients has started to emerge.


The strongest scientific evidence regarding supplements to help people who are infected with COVID-19 is for:


Vitamin D3

Vitamin B12






There is some scientific evidence for:



vitamin A

vitamin C



There is theoretical scientific evidence for:


phytonutrients such as polyphenols and flavonoids


The best evidence we have suggests that regarding COVID-19 infection, earlier supplementation is better
