Quercetin Supplement (QU995 Quercetin) for Allergies and Immunity Support

Our quercetin supplement — a specific quercetin extract named QU995® —has been developed to offer the benefits of the natural flavonol, quercetin. Also known as quercetol, this molecule is part of the large family of flavonoids, polyphenols that are known for their antioxidant potency.

Quercetin Supplement Benefits

Studies on quercetin for inflammation and immunity show that biological action from the polyphenol derived from plants may support the immune system. Other quercetin benefits may include anti-inflammatory, anti-carcinogenic, and antioxidant properties.

A systematic review of the flavonoid quercetin health benefits noted the following:

Antioxidant properties:

Quercetin may be one of the most powerful flavonoids in protecting the body against reactive oxygen species, with animal evidence supporting antioxidant effects and potential protection for the brain, heart, and other bodily tissues, against oxidative stress.

Anti-inflammation and allergy support:

Studies indicate quercetin’s benefits for inflammation may stem from how it inhibits the formation of prostaglandins, leukotrienes, as well as histamine release.


Quercetin is also being studied for its anti-proliferative effects in various harmful cell types in the body.

Additionally, studies on quercetin and exercise show promising interest in quercetin for the benefit of improving health and performance in athletes, specifically for post-exercise inflammation and oxidative stress, though further studies are required to determine the efficacy of those benefits.

While further research is needed to analyze the efficacy, safety, and use of quercetin supplements for humans, there is abundant research on quercetin that indicates its potential benefits.

Quercetin Supplement Side Effects

Before beginning a quercetin dietary supplement regimen — or any supplement regimen — for boosting overall health and wellness, you should first conduct your own research on the potential side effects.

Though the health benefits of quercetin supplements are being studied, there may be some quercetin side effects for certain people and those taking certain medications.

In addition to performing your own independent research using studies on the best quercetin supplements, you should also speak with your licensed medical care provider to ensure that taking quercetin is right for you, and that there will be no negative implications or drug interactions with any current prescriptions you may be taking.

In addition, anyone receiving immune-suppressant therapy should seek medical advice before taking quercetin as it can interfere with certain drugs, such as cyclosporine.

If you are currently pregnant, lactating, or may become pregnant in the near future, you should speak with your health care provider before taking quercetin supplements for allergies or for any other potential quercetin supplement health benefits.

If you experience any side effects while taking quercetin for immune system support — or for any other potential benefits — stop your regimen immediately and consult with your healthcare provider. You should wait until you have been approved by a licensed professional before proceeding with your regimen again.

What is quercetin? And how is it produced?

Quercetin is found in many plant-based foods, such as elderberries, blueberries, red onions, tea, and broccoli. It has also been identified in the pods and seeds of a tree native to Brazil called Dimorphandra mollis. Indeed, this is the natural source from which our supplement Super Quercetin is formulated.

The QU995® quercetin used in our high-quality product is obtained from a natural source.

Quercetin from dietary sources has received “Generally Recognized As Safe” (GRAS) status by the Food and Drug Administration (FDA). Super Quercetin, one of the best quercetin supplements for allergies, is extracted and purified using an exclusive proprietary process that ensures it is free from contaminants. The lack of contaminants ensures you get the most out of the potential QU995® benefits.

How To Take Quercetin Supplements

Our QU995 quercetin supplement is extracted from Dimorphandra mollis and standardized to 99.5% anhydrous quercetin. When you buy quercetin supplements from Supersmart, you’ll receive a bottle with 60 capsules. The only additional ingredient in Super Quercetin is acacia gum.

Each tablet of quercetin is 500mg, but the daily recommended intake for quercetin is 1000mg, so we recommend taking two capsules every day. The best time to take quercetin supplements is at the same time as any other supplements you take. The effects of quercetin for allergies and other benefits can also be boosted by combining it with other antioxidants, including Vitamin C, or other anti-inflammatories, such as bromelain.

Currently, there are no food intake restrictions for quercetin, but you should consult with your physician on when to take quercetin, and if you should or should not take more than our recommended daily serving of two 500mg quercetin supplement capsules. Your primary care physician can assist you — and may adjust the recommended serving — by suggesting the best daily mg serving amount for you.

Quercetin supplements are intended for healthy adults seeking to boost their overall health and wellness, and should not be consumed by children or pets. Keep your bottle of Super Quercetin out of reach of children and pets, and stored in a cool dry place.

Do not take supplements that have reached their expiration date. If your supplements expire, as indicated by the expiration date on the bottle, buy new supplements to ensure safety, and that you receive the top quercetin benefits suggested by current studies.
