What is Quercetin?

Quercetin is among the major flavonoids found in our diets. Flavonoids are a group of plant compounds that regulate cell cycle and activity. They also fight against free radicals which can cause oxidative stress if left unchecked.

As a plant pigment, quercetin is present in a lot of plant-based foods. These include onions, berries, kale, apples, and even green tea. On average, individuals consume around 10 to 100 mg of it every day through their regular diet.

Naturally, the quercetin molecule only has links with sugar molecules. There is no other substance involved. However, in supplements, it is present as a sole quercetin molecule or quercetin dihydrate molecule, which means it is attached to one or many water molecules.

Sometimes, the supplements also contain other components to improve performance. For example, quercetin supplements sometimes come with bromelain or vitamin C. Both of these substances improve its absorption in the human body.

Properties of Quercetin

Quercetin holds a special place amongst plant compounds and is known for the numerous benefits it can provide. Its ability to lessen the intensity of severe medical conditions lies in its unique chemical composition.

Also known as C15H10O7, quercetin exhibits three prominent categorical properties. These include:

Antioxidant Properties

An antioxidant refers to a substance capable of protecting cells from damage inflicted by free radicals which are unstable molecules released during the oxidation process.

Quercetin has antioxidant properties and helps by shielding cells from any potential harm. This maintains cell health and enables them to carry out activities free from the damaging effects of stress.

Anti-Inflammatory Properties

Inflammation is another word for swelling and pain. It can occur when chemical substances from white blood cells enter the bloodstream or tissues to fight invading germs. Quercetin possesses the ability to reduce swelling by blocking the substances cause it.

Antiproliferative Properties

When taken in appropriate amounts, quercetin also has the ability to prevent the spread of potentially harmful cells into surrounding tissues. These include malignant or tumor cells which means that quercetin has anti-cancer properties as well.

Health Effects Of Quercetin

With so many beneficial properties, quercetin offers plenty of health benefits too. A high-strength dose of it will instantly improve your mood and reduce pain in the body. And, a consistent intake over months yields even more amazing results.

One study concluded that quercetin can be used to combat aging. It eliminates aging cells and reduces the signs of aging in older individuals. Another review recorded increased endurance during exercise by those who took quercetin.

Here are the four significant benefits of quercetin:

Boosts Immune Health

Quercetin protects the cells from damage and reduces oxidative stress. In turn, this supports the body’s defense mechanism and enables it to be strong enough to fight off foreign molecules.

Reduces Inflammation

Generally, inflammation in the body causes slight redness and warmth. However, it can also trigger severe pain and high body temperatures. Since quercetin has anti-inflammatory properties, it eases the swelling and stress in muscles.

Lowers Risk of Chronic Brain Disorders

Chronic brain disorders refer to the existence of brain damage that results in permanent impairment. Such disorders include dementia, alzeihmers, and dystonia. Research shows that consuming quercetin can help lower the symptoms of chronic brain disorders in affected individuals and reduces the overall risk of acquiring these disorders in healthy people.

Improves Cardiac Health

Several human studies conducted by researchers found that quercetin had a positive impact on the heart health of participants. People who took in at least 500 mg of quercetin in the form of supplements saw a decrease in diastolic and systolic blood pressure.

Also, the plant pigment also helps regulate blood sugar levels. Thus, it is also beneficial for diabetics with complications.

How Do You Take Quercetin Powder?

The quercetin powder usually comes in capsule form. You can either swallow it using water, or you can open the capsule and mix the powder in your meal.

Since we all consume quercetin daily through food, you should watch how much of your supplement you take daily. The recommended daily value of of quercetin is 75 to 250 mg. You can consume this amount all at once or divide it into two doses.

Individuals with diets lacking plant-based foods may have higher requirements ranging from 500 to 1000mg. Do not consume the substance in higher doses than this without first speaking to a doctor.

Although quercetin is generally safe to use, it may cause mild side effects. These include headaches, tingling sensations, and nausea. Women who are pregnant or nursing should avoid quercetin consumption.

Also, people with kidney diseases should take these supplements with caution as consuming more than 1g of quercetin can cause damage to the kidneys.
