I have a confession to make. It took me a long time to add quercetin to my supplements.

I think it was because it sounded weird, I had never heard of it, and I didn’t think it would be important.

Wrong again!

What is quercetin?

Quercetin is a plant pigment (flavonoid). It is found in many plants and foods, such as red wine, onions, green tea, apples, and berries.

Research shows quercetin has many health benefits. “It is anti-inflammatory and has antibacterial and antiviral properties, making it ideal for avoiding infections and warding off sickness.

Quercetin is part of the FLCCC protocol.

I’ve looked at various articles and studies, they are quite complicated and technical, so instead of sharing those, I am going to have you read this very friendly article written by a chiropractor. It makes the data available in a form everyone can understand. Please take a look:


OK, now that you are hopefully convinced that you should not omit quercetin from your supplement regimen, there’s more!

My friend Barbara shared a newsletter from Dr Mercola with me which is all about quercetin (link below) Thank you, Barbara!

It’s a bit more technical than the article above, but very much worth reading,

Please note this comment inside the Mercola article:

“The quercetin used was a brand name formulated with sunflower lecithin, which has been demonstrated to increase absorption in the gut by as much as 20 times, compared to pure quercetin formulations.”


Here is a study that has measured the absorption of quercetin and mentions the 20X increase in absorption by including “phytosomes”.

If you do not want to read the study below, here is the conclusion which is the basis for Dr Mercola’s statement above regarding 20X absorption.

“A more soluble formulation of quercetin based on lecithin, Quercetin Phytosome, has recently been developed, and was found to facilitate the attainment of very high plasma levels of quercetin—up to 20 times more than usually obtained following a dose of quercetin—when the novel formulation was administered orally in human volunteers, and it did not have any notable side effects. These results suggest that Quercetin Phytosome allows the oral administration of quercetin in a safe and bioavailable manner, thus facilitating the effective utilization of this natural compound to treat various human diseases.”


Which one is the right one to take?

I have found only three formulations available on Amazon after scouring all of their offerings. If I missed one, please let me know. If you find another supplement that fits these requirements, please let me know.

The key words I looked for were “phytosome” , “phospholipid” or “sunflower lecithin”.

Some of these have added bromelain.

This article explains the role and benefits of bromelain (easy to read): https://vitamedica.com/wellness-blog/bromelain-and-quercetin-natural-anti-inflammatory-supplements/
