What Are Quercetin Benefits for Allergies and Side Effects?

Quercetin allergies

Allergic rhinitis is somewhat of an umbrella term, covering everything from pet allergies to dust allergies to mold allergies; even seasonal allergies symptoms are considered to be a part of allergic rhinitis. It’s a very common condition, with the American Academy of Allergy, Asthma, and Immunology estimating that between 10 and 30 percent of the population have suffered with allergic symptoms at one time or another. It’s not surprising that many people want to know how to cure allergies, but unfortunately there is no allergic rhinitis cure that’s 100 percent effective. However, there are a variety of remedies for allergies that can help to minimize symptoms, and reduce the risk of triggering symptoms in the future.

Many standard treatment options for allergic rhinitis have either proven to be ineffective, or contain ingredients like corticosteroids which could have long term health risks. That’s why more and more people are now looking into natural allergy medicine, like quercetin, which could be a good alternative.

Quercetin and allergies

What is Quercetin?

Quercetin is a flavanol, which is a type of antioxidant that’s often found in fruits, vegetables, and beans. Like other antioxidants, quercetin benefits the body by preventing oxidation processes from occurring. When cells in the body are placed under oxidative stress, they can quickly and easily become damaged.

Quercetin as an Allergy Remedy

Along with probiotics, quercetin is one of the most popular natural remedies for allergies. Experts believe that quercetin can help to manage allergic rhinitis symptoms in two different ways. Firstly, quercetin acts as a stimulant, and stimulates the immune system to produce a more effective and efficient response to common symptom triggers such as pollen in the summer. Secondly, quercetin is understood to have pretty powerful anti inflammatory properties. This means it’s great at reducing inflammation in the nose, getting rid of that flu-like feeling.

So does quercetin for allergies really work? Available research indicates that quercetin is a very effective treatment for allergic rhinitis. Studies have found that taking quercetin for at least 5 consecutive days can minimize instances of sneezing, and significantly reduce nasal itching, helping sufferers to live a more comfortable life.

Sources of Quercetin

Quercetin is one of the most widespread of the flavanols, and can be found in many different types of foods. Fennel, red onion, sweet potato, and kale are all good sources, as well as fruits like blueberries and cranberries, and herbs like dill and cilantro. Quercetin can even be found in black tea and red wine!

Quercetin Supplement and Dosage

For those who are concerned that they’re not getting enough quercetin in their everyday diet, quercetin supplements are also widely available, and are sold as either quercetin capsules or quercetin powder. There are no official guidelines relating to the recommended quercetin dosage, but research suggests that at least 25 mg/kg is required in order for it to be effective as a treatment for allergic rhinitis.

Is Quercetin Safe?

Quercetin is a ‘safe, natural therapy’, and as it is found naturally in foods, it is unlikely to cause damage to the body. There have been concerns about a potential link between quercetin and cancer, but due to limited evidence, quercetin is not classed as a carcinogenic, and quercetin side effects are rare. Many chewable vitamins for kids also contain quercetin due to the many benefits it offers. However, quercetin should be used with caution in people who are taking certain medications due to possible reactions. Quercetin has shown to have a number of possible interactions, including reducing the efficacy of antibiotics, and increasing the effects of blood thinners. In healthy people, however, quercetin is generally considered to be very safe.
