Is there any real difference in quality between brands of Quercetin? (Vanity)

I've been buying Thorne's Quercetin Phytosome but find it expensive. So I wonder is there any real difference in quality between brands of Quercetin?

It’s dangerous. Do your research, and save your money.

My first bottle was Swanson brand at 1/3 the cost.

[ryderann]

Ditto Swansons.

[Java4Jay]

How you mean dangerous? I did do lots of research and understand it to be beneficial.

I LOVE “NOW” Brand Anything! They have Quality Products, VERY reasonable prices! And yes, I have purchased their Quercetin before. Quercetin w/Bromelain 120 VegiCaps 17 dollars

That is complete rubbish.

I understand that Quercetin is hard for the body to absorb. That’s where I looked at studies that the Phytosome type had the best absorption rates. I could be just another bought study but normally ‘you get what you pay for’.

Quercetin is not cheap no matter where you buy it.

Do a search on it and compare prices.

I just did a search and found prices from .15 to .26 per capsule. Look around.

Thorne Quercetin Phytosome 250mg - Exclusive Phytosome Complex - $36 for a months supply

Swanson High Potency Quercetin 475mg
$10 for 2 month supply

Nutricost makes a decent product

The finer the powder, the better absorbed.

ConsumerLab.com tested quercetin and their picks were:

- BulkSupplements.com Quercetin Hydrate (11 cents per 500mg)
- MRM Quercetin (smallest grains)
- Solaray Quercetin

However, they tested few overall.

My wife and I get Now Foods Quercetin, but would get Swanson on one of their better sales.

That is the form we have.

“Quercetin is a plant flavonol from the flavonoid group of polyphenols. It is found in many fruits, vegetables, leaves, seeds, and grains; red onions and kale are common foods containing appreciable amounts of quercetin.”

“In preliminary human studies, oral intake of quercetin in doses up to one gram per day over three months did not cause adverse effects.”

Which part is “dangerous”?

[Osage Orange]

You post///but don't answer.

Why?

[Uncle Miltie]

The NIH on quercetin and ecgc’s zinc ionophore properties:

That's what I use. Get it from Amazon.

Yes, not really worth taking it unless bromelain is included or purchased à la carte.

Wife did some research and bought us Natural Factors Bioactive Quercetin EMIQ, supposedly 40 times greater absorption. 60 caps @ 50mg. Not sure the cost
