Does Quercetin Boost Immune System?

The human body cannot function without nutrients and compounds like antioxidants. We need them for a stable metabolism and healthy lifestyle. And subconsciously, we consume healthy foods daily that provide us with these supplements. One such antioxidant is Quercetin.

Quercetin is a chemical that you will find in many foods you eat. They belong to a class of plant compounds known as flavonoids. Foods like fruits, vegetables, wine, tea, etc., are all rich in flavonoids. On average, an individual consumes up to 100 mg of Quercetin daily through various food sources.

Fruits and vegetables like onions, broccoli, berries, apples, etc., which we eat daily, have Quercetin in them. It is also found in red wines, grains, green tea, and herbs like American elder and St. John’s wort.

As you can see, these foods are rich in antioxidants. And Quercetin is one of the essential ones beneficial for many reasons. Their potential to function as antioxidants make them beneficial for the human body.

Quercetin has many uses and applications in the field of science and medicine. And we have listed a few of them below. Let us take a look.

Uses of Quercetin

Some of the many uses of Quercetin are as follows.

They have the potential to cure allergies.

When we have allergies, the body produces an inflammatory chemical known as histamine. This leads to reactions like itching, swelling, and sneezing.

Quercetin has the potential to prevent such allergic reactions from happening. However, this has not yet been approved. But the good news is laboratory studies on test tubes, and animals have shown promising results.

These tests showed that Quercetin might prevent the occurrence of enzymes that lead to inflammation. Consequently, this blocks and suppresses chemicals like histamine. For instance, one test showed that Quercetin could suppress peanut-related reactions in mice.

However, it is not yet clear whether this can have the same effect on humans. We need more research before buying Quercetin as a drug for allergies.

They are used by athletes.

Tests and studies have shown that Quercetin can also improve endurance in athletes. However, the improvement is minimal and not too drastic. In a 2011 study, the researchers measured the oxygen consumption of the test subjects to come up with this result.

Another study in 2013 yielded a better result. Sixty male athletes were given a dose of Quercetin and took an active part in athletics. After three years, they showed improvement in body mass, calorie maintenance, etc., after taking Quercetin.

However, this method is unhealthy and should only be used as a last resort.

They are used for testing anti-cancer effects.

Quercetin is an antioxidant that makes it a possible candidate to fight cancer cells. Lab tests in animals and in-vitro experiments showed that Quercetin could contain growth and eliminate specific cancer cells like lung cancer and leukemia.

Further studies also provide similar results with blood, ovarian, bladder, and liver cancer cells. In 2010, a research team took lung tissue samples from adenocarcinoma patients. They observed genetic changes after the Quercetin effect.

Promising as they may be, Quercetin still has a long way before it can play a role in cancer treatment.

They can reduce inflammation.

According to research, free radicals not only damage your cells but promote unwanted inflammation as well. Of course, our body requires a minor inflammation for healing and fighting infections. But if the condition persists, your health is the culprit.

Cancers and heart and kidney complications can lead to such problems. But Quercetin is shown to help bring an end to this.

During in-vitro experiments, researchers observed that Quercetin could reduce inflammation in cells. In another study that lasted eight weeks, subjects with rheumatoid arthritis were given Quercetin in mild doses. And this test yielded promising results. They showed improved health conditions compared to the placebo group.

They keep your blood pressure levels in check.

Quercetin has been tested on mice to check if they are compatible with regulating blood pressure. And the results were fruitful.

Thus, in 2016, a total of 580 individuals were subjected to 500 mg of Quercetin daily. The results showed that Quercetin helped reduce both systolic and diastolic blood pressure. They were able to reduce their blood pressure by 5.8 mm Hg and 2.6 mm Hg, respectively.

However, we still need confirmation on the precise dosage and treatment duration.

They might help tackle chronic brain disease.

The antioxidant properties of Quercetin have the potential to tackle brain disorders like dementia and Alzheimer’s disease.

In lab studies, mice with Alzheimer’s disease were given mild Quercetin injections for 3 months. After the study, Quercetin helped eliminate the disease markers. Plus, the mice performed better during tests.

It will help if you note that some of these benefits are not fully proven. Tests and experiments are still ongoing, and the results are looking promising. And if you want to employ such treatment methods, consult your healthcare provider first.

Does Quercetin boost immune system?

Quercetin has several health benefits and can boost your immune system. They are potent antioxidants that can cure cancer and brain disorders.

Antioxidants like Quercetin eliminate the chemical by-products like free radicals, which have harmful effects on the cell membranes and DNA structure. These free radicals are unstable and can increase the risk of chronic diseases like cancer and diabetes.

The presence of Quercetin in our immune system helps prevent such conditions. Furthermore, they can also kill cancer cells, take care of your heart, and regulate blood sugar levels.

Quercetin may also help reduce signs of aging and decrease allergies and inflammations. All these factors are necessary for a healthy immune system. And Quercetin, as a supplement, is an excellent choice if you’re looking for a boost.
