How to choose the right quercetin supplement?
When picking the best quality quercetin supplement, consider if the product has:
- Enhanced bioavailability. Look for supplements that enhance quercetin's bioavailability. The body does not absorb quercetin easily, so formulations that include enhancers like bromelain or liposomal technology can improve its absorption.
- Adequate dosing. Check the dosage of quercetin per serving. Typical doses in studies have ranged from 500 to 1,000 mg per day. Ensure the product allows you to adjust your intake to suit your needs.
- Quality of ingredients. Opt for supplements free from unnecessary fillers, artificial colors, and preservatives. If you have allergies or dietary restrictions, look for products that meet these requirements, such as non-GMO or gluten-free options.
- Certifications. Choose products that third-party organizations have tested for purity and potency. Certifications from organizations like NSF International or US Pharmacopeia (USP) can assure quality.
- Positive customer reviews. Research the brand's reputation, including customer reviews and transparency regarding sourcing, manufacturing processes, and testing protocols. Trustworthy brands will be forthcoming with this information on their website.
- Good value for the price. Compare prices and consider the cost per dose to find a supplement that provides good value without compromising quality. Remember, the most expensive option is not always the best.
Disclaimer — Always follow the recommended dosage on the product label and discuss with your healthcare provider, especially if you have existing health conditions or take other medications. Pregnant and breastfeeding women should avoid quercetin supplements due to insufficient safety data.
What is quercetin?
is a naturally occurring flavonoid, found abundantly in fruits, vegetables, and grains. It's recognized for its potent antioxidant properties, which may help combat free radical damage.
As an extracted supplement, it's typically used for its purported health benefits. Preliminary studies suggest it could help with:
- Preventing and managing coronary and heart disease.
- Managing allergy symptoms endurance and performance.
- Protecting brain cells from damage through antioxidant properties, potentially lowering the risk of neurodegenerative diseases like Alzheimer's and Parkinson's.
- Reduce inflammation and its associated health problems, including arthritis and chronic pain.
However, these benefits need further confirmation from extensive human trials.
While generally deemed safe, quercetin could potentially cause side effects when consumed in high doses.
Benefits of quercetin supplements
Currently, clinical studies are exploring several potential benefits of quercetin, including its effects on cardiovascular health, allergy relief, athletic performance, brain health, and inflammation. In the following section, we'll examine each of these areas in more detail.
Quercetin is believed to support cardiovascular health by enhancing the elasticity of blood vessels, reducing inflammation, and potentially lowering blood pressure.
Its antioxidant properties help combat oxidative stress, a key factor in heart disease.
Additionally, some research suggests quercetin may inhibit the aggregation of platelets, which can decrease the risk of blood clots and related cardiovascular events.
Quercetin may alleviate allergy symptoms by stabilizing mast cells, which release histamine, a primary chemical involved in allergic reactions.
It also has anti-inflammatory properties, which may reduce swelling and inflammation associated with allergies. Thus, quercetin could potentially help manage symptoms such as sneezing, runny nose, and itching.
Quercetin may enhance athletic performance by increasing endurance and reducing fatigue.
It's believed to improve mitochondrial biogenesis in muscle and brain cells, essentially creating more energy powerhouses in these cells. This could lead to better exercise capacity.
Additionally, its anti-inflammatory and antioxidant properties may help speed up recovery after intense workouts by reducing muscle damage and inflammation.
Quercetin can support brain health due to its antioxidant and anti-inflammatory properties. It may help protect neurons from oxidative stress, a factor implicated in neurodegenerative diseases like Alzheimer's and Parkinson's.
Some research suggests quercetin could inhibit the formation of harmful plaques in the brain associated with Alzheimer's disease. Its anti-inflammatory effects might also reduce chronic inflammation, a contributor to cognitive decline.
Quercetin's potent anti-inflammatory properties can help reduce general inflammation. It works by inhibiting the production and activity of pro-inflammatory substances like cytokines and enzymes.
This makes quercetin potentially beneficial in managing conditions associated with chronic inflammation, such as arthritis, heart disease, and certain skin disorders.
Quercetin’s antioxidant properties also help protect cells from damage caused by inflammatory processes.
Best form of quercetin supplement
The best form of quercetin supplement depends on its bioavailability, which measures how easily a substance can be absorbed and used by the body. Quercetin naturally has poor bioavailability, so choosing a form that enhances absorption is key.
These are the common forms of quercetin:
- Quercetin dihydrate. A chemically modified form of quercetin supplement increasing its high bioavailability, helping the body absorb and use the supplement.
- Quercetin complex. Includes additional compounds like bromelain, a digestive enzyme derived from pineapples, and vitamin C. These added compounds may enhance the absorption of quercetin into the body.
- Quercetin phytosome. A more recent formulation where quercetin is bound to a type of fat molecule, which further enhances its absorption within the body.
Possible side effects of quercetin supplements
While quercetin supplements are generally considered safe for most people, they can cause side effects in some cases, especially when taken in high doses. These can include:
- Digestive issues. Some people may experience stomach upset, indigestion, acid reflux, or diarrhea.
- Headaches and tingling. Quercetin may cause headaches or a tingling sensation in the arms and legs.
- Kidney damage. Very high doses of quercetin may potentially harm the kidneys.
- Interactions with medications. Quercetin can interact with certain medications, such as antibiotics or blood thinners, potentially affecting how they work.
How to take quercetin supplements for best absorption?
Quercetin is a beneficial flavonoid found in many plants, but the main challenge with quercetin supplements is their low solubility and absorption.
To boost quercetin absorption, you can take quercetin supplement with a meal that includes healthy fats. For example, meals could include fat-rich foods like avocados, nuts, olive oil, almonds, peanut butter, Greek yogurt and oily fish. Fats help dissolve quercetin, making it easier for your body to absorb.
Also, you may look for supplements formulated with liposomal delivery systems or include the ingredient - bromelain. Bromelain is an enzyme extracted from pineapple that is suggested to increase the absorption of quercetin.
In conclusion, choosing the right quercetin supplement requires thoughtful consideration of several factors, including bioavailability enhancements, appropriate dosages, ingredient quality, certifications for purity and potency, and the reputation and transparency of the brand.
Quercetin offers a wide range of potential health benefits, from cardiovascular support and allergy relief to improved athletic performance and brain health, thanks to its potent antioxidant and anti-inflammatory properties. However, due to its naturally poor bioavailability, it is essential to opt for supplements with enhanced absorption due to bromelain or liposomal technology.
While quercetin supplements are safe for most people, they can interact with certain medications and may not be suitable for everyone, especially at high doses. Therefore, consulting with a healthcare provider before use is highly recommended.

Does quercetin increase testosterone?
Potentially yes, although more research is needed. Some studies suggest quercetin may potentially boost testosterone effects through inhibiting its metabolism, but human studies are lacking. Therefore, it's not yet clear whether quercetin can reliably increase testosterone levels in humans.
How do you take quercetin for best absorption?
To enhance the absorption of quercetin, choose supplements that use formulations improving bioavailability. These might include quercetin dihydrate or complexes that include bromelain or vitamin C. Taking the supplement with a meal containing healthy fats may further increase absorption.
