What is Quercetin?

Quercetin is one of the most prominent and researched bioflavonoid compounds in plants. Although it exists in smaller quantities, you can find Quercetin in foods such as onions or grapes. Berries, citrus fruits, broccoli, and tomatoes are other Quercetin foods high in Quercetin. One of the aspects that makes Quercetin benefits unique is its interaction and synergy with other compounds. Quercetin has been shown to promote balanced oxidation levels by blocking an enzyme called catechol-o-methyltransferase (COMT).* Interestingly enough, some studies found that Quercetin supports the cellular absorption of green tea catechins by inhibiting COMT, thus demonstrating a synergistic relationship between Quercetin and Green Tea catechins. As a result, Quercetin may help promote the bioavailability of Green Tea catechins! 

Quercetin is also known to be an adenosine receptor antagonist, like caffeine. However, its effects are not going to be as noticeable as caffeine, but may provide you with a subtle spring in your step! Some additional research has also found that taking a Quercetin supplement can help support balanced inflammation levels in the brain which may help promote overall cognitive function.*

Quercetin Benefits and Uses

    • May help support cognitive function*
    • May help promote balanced oxidation levels*
    • May help support balanced inflammation levels*
    • May help promote bioavailability of other supplements*
    • May help support immune system function*

Quercetin Zinc Ionophore Activity

As discussed earlier, Quercetin has shown to be effective at supporting balanced inflammation levels through multiple pathways. However, that is not the most interesting research subject on Quercetin. Quercetin has been a popular research subject since it seems to play a role in several cellular processes. One element of interest is that Quercetin demonstrates zinc ionophore activity. A zinc ionophore is a compound that helps transport zinc into cells. This behavior is under more research and many believe that Quercetin’s role as a zinc ionophore makes it good at promoting immune system function and supporting other quercetin health benefits. Research has already shown that a Quercetin supplement may help effectively shuttle zinc throughout the body into harmful cells. Additionally, this activity was further enhanced when paired with EGCG. 

Although its mechanisms are still being researched, studies have shown that Quercetin benefits overall immune system function and helps support balanced oxidation levels. However, the Quercetin health benefits of taking a Quercetin supplement are still widely being researched and investigated.

Quercetin Stacks

Balanced Oxidation Levels Stack: Quercetin With Green Tea Extract + Piperine

This combination promotes a synergistic approach to balancing oxidation levels and promotes the bioavailability of Green Tea Extract providing an effective and well rounded approach to balancing oxidation levels.*

Immune System Support Stack: Quercetin With MicroZinc

This pair is a potent combination of an ultra bioavailable form of Zinc and Quercetin as a zinc ionophore. Quercetin further promotes the bioavailability and body’s use of MicroZinc, which is already much more bioavailable than traditional forms of Zinc. Adding Quercetin takes Zinc absorption to the next level!*

Balanced Inflammation Levels Stack: Quercetin With OptimALA

This dual mechanism approach to inflammation helps promote well balanced inflammation levels while also supporting energy levels. The versatility of Quercetin and OptimALA may also help support cognitive function as well, making this combination great for balancing inflammation levels with added benefits.*

Quercetin Dosage

As a dietary supplement, take one Quercetin tablet daily.

    Quercetin 50 mg. tablets

    Posted by Louise DeBernay on 27th Apr 2022

    Recommended by an X- employee of one of the big pharma companies to help counteract the effects of the pandemic shot to build the immune system. It should be taken along with zinc, vitamin D-3 and vitamin C. So far so good! Quercetin has had absolutely NO side effects, and I'm still healthy! I will continue to take this forever, at this point! This porduct has done what it is supposed to do, and kept me well!

    Quercetin 50 mg. tablets

    Posted by Louise DeBernay on 16th Feb 2022

    No ill effects! Assume that it is working to help boost my immune system. I do cut them in half as they are easier to swallow that way.

    Great Product

    Posted by Mark on 10th Feb 2022

    This is great the only reason it lost a star in my rating is because I think it would be better in capsule form if possible. The tablet tends to get stuck on your tongue/throat. A bit harder to swallow than most but it gets the job done.

    Good quality

    Posted by Robert Robinette on 17th Jun 2021

    These give me citrusy burps for a couple of hours after I take them. Who knows if they're helping, but longevity research looks promising.

    Amazing

    Posted by Daniel on 1st Jan 2021

    Great to combine with green tea and piperine. Also great on its own. Highest quality around, affordable, and quercetin is a safe flavonoid that just about anyone can benefit from. I take it every day

    it's definitely Quercetin

    Posted by Matt on 18th Nov 2020

    I get a 'flushing' feeling when dosing which is similar to caffeine possibly caused by histamine or because parts of it cross the BBB, this is just acute dosing though not through chronic use

    Quercetin Tablets | 500mg | 95% Anhydrous Quercetin

    Posted by Alexander Wendt on 25th Oct 2020

    I rarely write reviews - but this one was good in an unexpected way. Mainly bought it for the immune-boosting and anti-oxidant effects. But unlike other quercetin products I've tried, it gives me a noticeable boost in motivation and moderate stimulation. Definetely recommended!

    I've been waiting for quercetin tested by ND for some time, extremely cheap staple and amazing combo with NMN. Makes me so happy we finally live in a world with access to shit like this
