Are you looking for the best Quercetin supplement to support your immune system, cardiovascular function, and cellular health? 

We are proud to introduce a brand new Quercetin supplement, Quercetin Synergy

More than just another Quercetin supplement, this formula contains Quercetin, Wellemon™ lemon extract, and Turmeric to support a healthy immune response, healthy mast cell function, and respiratory and cardiovascular health.* 

Why did we add Wellemon and Turmeric to a Quercetin formula? The answer may surprise you.

Read on to discover the benefits and synergy behind the ingredients in our new Quercetin Synergy ingredients.

The Surprising Synergy Between Quercetin, Wellemon, and Turmeric

Quercetin has become a popular supplement, especially during pollen season and for those seeking natural immune, sinus, or heart support*.

So, what’s different about Gaia Herbs Quercetin Synergy?

In this formula, we sought to surround and support the benefits of Quercetin with bioavailable Wellemon® lemon fruit extract and Turmeric/Curcumin*.

We’ll cover the benefits and details of each ingredient in the following sections and offer an overview of the synergistic components of the three ingredients.

  • Quercetin and Curcumin: The main active plant compound in Turmeric—are polyphenol antioxidants and flavonoids with various overlapping benefits (which we’ll discuss in more detail shortly). Preliminary studies suggest a synergistic benefit of combining Quercetin and Turmeric/Curcumin for respiratory function.REF#2772
  • Wellemon: A type of bioavailable flavonoid extracted from lemons*.

Any of these ingredients may be beneficial if taken alone, hence all the basic Quercetin supplements out there.

However, when we combine these three yellow flavonoids, the result is a synergistic formula offering broad-spectrum support for cellular, immune, respiratory, skin, and cardiovascular function*.

Now that you understand the synergy aspect let’s take a closer look at each ingredient.


Quercetin is a flavonoid polyphenol antioxidant and plant pigment that gives its signature bright colors to fruits, vegetables, and herbs. 

It’s one of the most studied and prevalent flavonoids found in foods, with research suggesting it may provide a range of benefits*.

What is a Flavonoid Antioxidant?

Flavonoids are a diverse group of natural substances found in plants such as fruits, vegetables, herbs, nuts, wine, and seeds.REF#2773 REF#2774

Antioxidants can be man-made or natural substances that support cell health in the presence of free radicals (unstable molecules).REF#2775

Antioxidants are produced by our bodies and can also be found in fruits, vegetables, herbs, wine, meats, and other foods. 

Examples of antioxidants include vitamins C, and E, selenium, carotenoids such as Lycopene, and flavonoids such as Quercetin.

Research suggests Quercetin may provide the following benefits:* 

  • Quercetin may support normal histamine functionREF#5776 REF#2777 REF#2778
  • Quercetin may promote normal immune function REF#2779
  • Quercetin may support heart and cardiovascular function REF#2780

The Quercetin used in Gaia Herbs formulas is a natural plant-based Quercetin isolate derived from the Brazillian Fava d’anta tree, and is obtained without the use of harsh solvents.

It is also vegan, gluten-free, and third-party tested for identity, purity, and contaminants.

Wellemon®: Bioavailable Lemon Fruit Extract 

If you’re wondering why you’ve never heard of Wellemon®, that’s because it’s a relatively new nutraceutical ingredient.

Wellemon is a natural full-spectrum flavonone extract from whole, sustainably-sourced Spanish lemon fruits (citrus limon L.). 

It contains eriocitrin, a plant substance with antioxidant properties.REF#2781

Flavanones, like Wellemon, are a type of flavonoid that helps optimize absorption of vitamin C.REF#2782

Wellemon contains a potent source of eriocitrin from lemons. Eriocitrin is a plant substance with antioxidant properties.REF#2783

Preliminary research suggests the eriocitrin in Wellemon may be more absorbable than hesperidin, the typical flavonoid sourced from oranges.REF#2784

Hesperidin found in citrus bioflavonoids which are used in many Vitamin C products, for example, is used in many types of supplements.

This suggests Wellemon may provide a higher total concentration of bioactive metabolites which may support various aspects of health, including:

  • Cell function
  • Cardiovascular function
  • Immune function

In addition to its synergistic properties and benefits, we chose Wellemon for Quercetin Synergy for its bioavailability , sustainable sourcing, and clean extraction methods (water-only standardization method).

Turmeric: “The Golden Spice”

Turmeric, and its active plant compound Curcumin, are some of the most popular and most-studied herbal supplements.REF#2785 REF#2786

The Turmeric used in Quercetin Synergy is a concentrated Curcumin extract. 

For those who revel in the details, we chose this more concentrated source of Curcumin due to the research mentioned above on its synergistic relationship to Quercetin. You may also notice this product does not contain Black Pepper for enhanced absorption, like our other Turmeric formulas. 

This is intentional as Quercetin has similar bioavailability-support properties as Black Pepper.

Some additional benefits of Turmeric/Curcumin, according to research, include:

  • Antioxidant support REF#2787
  • Heart and cardiovascular support REF#2788
  • Promoting respiratory function REF#2789

Turmeric/Curcumin’s well-documented supportive effects on respiratory, and cardiovascular function make it the perfect addition to Quercetin Synergy.

As always, the Turmeric/Curcumin used in Gaia Herbs’ formulas is sustainably sourced, tested for heavy metals, and extracted using only ethanol and water—not acetone like typical extracts.

Quercetin Synergy offers a convenient way to take advantage of these three powerful yellow polyphenols for everyday support of respiratory, sinus, and cardiovascular function.
