Life Extension has Bio-Quercetin phytosome in a dose of 29mg that contains 10 mg quercetin \[from Japanese sophora concentrate (flower bud)\], phosphatidylcholine complex \[from sunflower\]) and they say to only take 1 capsule daily.
Thorne has Quercetin Phytosome (Sophora japonica concentrate (leaf) / Phospholipid complex from Sunflower) in a dose of 250 mg and they say to take 1 capsule two to three times daily.
Dr. Mercola's Quercetin Phytosome also contains 250 mg per capsule.
In this study they also used tablets of 250 mg Quercetin Phytosome: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6418071/
In this trial for covid19 they will give tablets of 500 mg Quercetin Phytosome twice a day: https://clinicaltrials.gov/ct2/show/NCT04578158
What is the difference between Life Extension's Quercetin Phytosome that has a very low dose and the other products of Quercetin Phytosome that have a higher dose?
What would be the equivalent dose of regular Quercetin for the Life Extension Quercetin Phytosome of 29 mg and for the Thorne Quercetin Phytosome of 250 mg?

I am not actually sure... That seems like a very low dose for the Life Extension one. Let me see if I can figure out what the deal is.
