There is a lot of information, and unfortunately a lot of misinformation, about using natural supplements to boost your immunity. Many supplements have anti-viral properties and are being extensively studied this very moment for their effectiveness in the face of our current pandemic, so I am going to link you directly to these studies so that you can read them for yourself.

I also am giving you direct links to all the current clinical trials registered in the US National Library of Medicine that are being conducted for each supplement.

Here are the top 10 most medically studied immune boosting supplements, in order of most studied to least studied.


Here we go:

The Top 10 Supplements Being Studied

6. Black Cumin Seed Oil

Here are some new medical studies looking into the antiviral properties of Black Cumin Seed oil:


There are 3 ongoing clinical trials testing the use of

Nigella sativa against coronavirus infection…

7. Quercetin


Quercetin is a sort of “natural antihistamine” that I’ve long recommended to my patients who have seasonal allergies, as it helps decrease reactivity to allergens. So it makes sense that quercetin might play a role in decreasing lung reactivty:

Medical studies looking at quercetin include:


Currently there are 2 ongoing clinical trials looking at

quercetin’s role in coronavirus…

…which you can read about right here.



8. Curcumin


Curcumin is one of my favorite anti-inflammatories of all time. So it makes me so happy to see that curcumin is now being investigated as a therapeutic agent to decrease the inflammatory response of the body during viral infection.

Here are some great medical studies you can read:


There is only one ongoing clinical trial looking at

a combination treatment (that includes curcumin) to treat covid19…

you can read that here.




9. Glutathione


Ever since news that this New Yorker seems to have massively improved after taking large does of glutathione during her illness, there have been a lot of talk over glutathione’s role, if any, in preventive care.

Unfortunately, the medical studies on this supplement are slim and there are currently no ongoing clinical trials investigating it’s role in covid19 therapy.


There is one current study looking at the role

of glutathione in Covid severity…

you can read that here.


10. Echinacea


There are a few medical studies looking at the anti-viral properties of echinacea… but no current clinical trail as of yet. Studies that may interested you include:


No current Covid19 clinical trials.
