Best Health Benefits of Natural Quercetin Supplements

Quercetin is a natural flavonoid that can be recognized as the beautiful silver-purple color that it gives some vegetables and flowers. Most notably, it can be seen in onions, which have one of the highest concentrations of quercetin. The high concentration of quercetin in onions can be attributed to the unique feeling of freshness and clarity that you get while eating them.

This is a completely natural compound that can be isolated for consumption in supplement form. It works as a natural antihistamine by restoring proper function of histamine and its levels within your body. This stuff also works by helping to stabilize mast cells, which are known for their regulations of allergic reactions by your immune system.

Besides being a non-drowsy and non habit-forming natural antihistamine, quercetin supplements can also offer you a wide range of side health benefits as well, including:

  • Helping to ease and prevent seasonal allergy symptoms
  • Helping to ease food allergy symptoms
  • An improved mental cognition and awareness
  • Reducing high levels of systemic inflammation
  • Healthy stimulating of the nervous system
  • Antioxidant benefits
  • Improving mood and focus
  • Healthy boost in energy levels
  • Restoring proper function of the respiratory system
  • Reducing mucus in the lungs and airways
  • Protection of sensitive brain cells
  • Reduction of high levels of bad LDL cholesterol
  • Promoting proper blood flow
  • Preventing cancer and degenerative diseases

Natural sources of quercetin in food

Natural Food Sources of Quercetin

You can tell that a fruit or vegetable contains quercetin if it is pigmented with red, green or purple. These foods are known for their visually-interesting color that matches with its particular taste. As an example, grapes and wine have that deep purple-red color that shows its concentration of quercetin. From a taste standpoint, you could easily recognize the taste of quercetin by remembering similarities in tastes between grapes, wine and onions. There is that bold, almost metallic flavor to it that matches in its aroma.

The concentration of quercetin can vary depending on a few factors, which include:

  • Where the food source is grown on the planet
  • The quality of soil the crop is grown in
  • The nutritional quality of the developing food crop until it was harvested
  • How fresh the fruit or vegetable is
  • How it is preserved and prepared, as well as its packaging
  • The type of food that it is

The best sources of quercetin in food are going to include the ones with those deep pigments. Not only that, the most ideal sources are the ones that you can usually consume a large amount of at once. Therefore, concentration, as well as quantity of the actual type of food, will determine how much quercetin you are actually receiving.

Typically, you will hear that the best sources of quercetin are from tea, red wine and dark fruits like blackberries and cherries. However, you really can’t eat a larger amount of these because they are unhealthy in excessive quantities. Obviously, too much sugar or caffeine are going to prove detrimental to your long-term health.

If you are trying to get more quercetin in your diet, your best bet will be to get it from dark leafy greens like in spring mix and kale. You can eat a large amount of this because it is low calorie and free of sugar. Of course, you can add other quercetin-containing ingredients to make yourself a super healthy flavonoid salad.

You could add:

  • Apples
  • Peppers
  • Berries (blackberries and blueberries are the best)
  • Red onions
  • Tomatoes
  • Capers (Known to have the highest concentration of quercetin by mass)

While you are eating your quercetin-powered salad, you can drink a healthy beverage that adds a bit more. Green tea with lemon contains a significant amount as well.

Quercetin Supplement health benefits list

Explaining the Benefits of Quercetin Supplements:

  1. Quercetin Helps to Lower Systemic Inflammation

Many kinds of bioflavonoids across the board can act as potent anti-inflammatories that will soothe damaging inflammation throughout your body. The mode of action occurs due to flavonoids’ ability to act as antioxidants, which fight the effects of aging and toxicity from our normal daily lives. Free radicals develop in our bodies when we don’t even know it, so adding an extra antioxidant punch is never a bad idea.

It’s better to be safe than sorry when considering these disruptive particles that could potentially damage the DNA in your cells. If your body has a high amount of oxidizing free radicals, this puts your cells at risk for mutation and death. Cellular mutation can potentially lead to cancer and other life-threatening conditions. Thankfully, antioxidants prevent oxidants from causing damage by neutralizing their chemical charge so that your body has an easier time eliminating them.

In fact, many medical science researchers suggest that high levels of inflammation may be the root cause of the majority of conditions and diseases that we face. From heart disease to Alzheimer’s, inflammation seems to be present in almost all health problems, even acne.

Medical health practitioners suggest that natural quercetin supplements can be used in treating certain conditions that evolve from inflammation. Those include high cholesterol, asthma and hay fever, memory loss, fatigue, skin conditions, cancer and viral infections.

2. Helps Mediate Histamine Response During Allergic Reactions

This natural compound has been shown in clinical trials to control the body’s natural release of histamine, leukotrienes and prostaglandins. All of these chemicals are involved in the process of mediating reactions due to hay fever. These three compounds play a significant part in contributing to the development of symptoms like sneezing and congestion when exposed to pollen that your body is allergic to.

Quercetin can be considered an antihistamine like Diphenhydramine or Cetirizine, but it is completely natural and not manufactured in a lab. How it works is that it prevents Histamine H1 Receptor gene expression. This suppresses the protein kinase C’s activation.

How you will recognize these modes of actions is through feelings of freshness and clarity, rather than suffering from symptoms like congestion, sneezing and running nose. That’s typically what you want to be achieved from an over-the-counter antihistamine anyway. Many people who prefer natural supplements due to their lack of long-term risks of use and wariness of over-the-counter drugs are switching to quercetin for their hay fever symptoms.

3. Quercetin May Powerfully Benefit Your Brain

Being a reducer of oxidative stress, quercetin can help make sure that your brain is in a non-toxic state. Its benefits can even reach the brain by making sure that your blood is purified of potentially-damaging free radicals before it reaches your brain and the other organs in your head.

Natural quercetin has the ability to improve superoxide dismutase (Also known as SOD) levels and decrease malondialdehyde (MDA), which can potentially cause your brain unnecessary stress. Most flavonoids can block the progression of inflammatory chemicals that can cause degenerative brain disorders like dementia and Alzheimer’s disease. This action can also potentially act as a treatment for viral and bacterial meningitis, HIV/AIDS related dementia and stroke via multiple causes.

When administered to mice in a controlled study, quercetin was able to reverse the effects of the cognitive decline in these mice. It had shown especially effective for mice intoxicated with lipopolysaccharides and in the older subjects. Treatment with quercetin products also seemed to prevent disorders like schizophrenia and Parkinson’s.

4. Quercetin May Assist in Weight Management

In similar studies that involved monitoring the effects flavonoids had on mice, it seems that quercetin supplementation helped to reduce fat gain by almost 50%. Researchers concluded that this may be due to quercetin’s ability to block the production of fat cells and trigger the destruction of existing fat cells to be eliminated from the body.

Supplementation also seemed to stabilize insulin levels and glucose intolerance in the mice subjects. Perhaps quercetin’s ability to soothe system inflammation plays a role in this as well, by allowing inflamed fat cells to perform their proper function or be utilized for energy effectively. All of the actions that this antioxidant provides helps the root causes of obesity and excessive weight gain. That’s not considering excessive food intake, of course.

5. Quercetin Supports Normal Respiratory Function and Health

It is not a common problem today for people to suffer from excessively irritated lungs and airways. After all, we constantly breathe in smoke from nicotine and fumes from the engines of vehicles whether we intend to or not.

When your respiratory tract is inflamed due to exposure to these environmental poisons, your immune system can produce histamine as a response. This can be detrimental even though this is a natural bodily function because histamine can promote more inflammation and irritation.

When supplemented with quercetin, its antihistamine effects can influence cellular enzymes to reduce and block histamine that can cause inflammation. This stops the downward spiral of histamine-induced inflammation that your body could create for itself. The mechanism of action will present itself as relief from watering eyes, running nose and facial swelling.

In addition to all of this, some animal studies suggest that quercetin can dilate the airway muscles to more easily allow fresh air to flow into your lungs. That also means that polluted toxins can be more easily exhaled and released out of your body. Research suggests that quercetin allows your upper respiratory tract to relax, soothed from constricting inflammation.

6. Promotes Proper and Functional Heart and Circulatory Health

Numerous studies highly suggest that quercetin may be able to assist in heart health. This is also true for most flavonoids in general.

There may be two reasons in particular that they are great for your heart. First of all, quercetin promotes blood flow without increasing blood pressure above normal levels. This action is essential for healthy transport of nutrients throughout your body. Your blood is responsible for carrying all the vitamins and minerals to the locations that need them after you eat healthy meals.

On the other hand, researchers believe that the antioxidant potential of flavonoids can help protect against high levels of LDL cholesterol oxidation. This means that it will prevent the collection of bad cholesterol in your arteries, causing plaque that may lead to heart disease, heart attacks, or stroke.

7. Promotes Skin Health and Prevents Acne Caused by Allergies

Through its effective antioxidant profile, quercetin works especially to reduce the oxidation of your skin cells. Personally, I have noticed that quercetin had improved the radiance of my skin after using it for some time. I take it as a natural replacement for over-the-counter antihistamines when pollen counts are high during allergy seasons.

Since quercetin is able to block mast cells from triggering immune reactions, this shows itself by preventing disorders like dermatitis and photosensitivity. Perhaps quercetin could even prevent skin cancer by protecting from damage by the sun.

If your allergies to food or pollen are causing acne as a symptom, then quercetin would likely work wonderfully for you. It would treat the root cause of your acne problem, like it did for me.

Side Effects of Supplementing With Quercetin Regularly

Of course this flavonoid is natural and offers a wide range of wonderful health benefits. However, there are always considerations to be made before supplementing with anything for the long-term. That includes natural products.

It should be noted that inappropriately high doses of quercetin taken through concentrated supplements may put stress on the kidneys. That means that a mild to moderate dose of quercetin is necessary to prevent causing the problems you intended to treat in the first place.

Also consider some potential interactions with other drugs or supplements that you may be taking. Quercetin may cause interactions with blood thinners, corticosteroids and aspirin. Always consult your doctor before adding any supplement to your regimen, especially if you are already taking one of these. However, most healthy people should have no problem consuming quercetin from its food sources. It is the supplemented form that should be the cause for some potential concern in these cases.

Bottom Line for Quercetin’s Health Benefits

I personally love quercetin because it has helped act as a replacement for OTC antihistamines, which I used to be addicted to. If I stopped taking Benadryl or Zyrtec, I would get these strange antihistamine withdrawal symptoms that ranged from itching to brain fog.

Quercetin, on the other hand, does not produce any withdrawal effects if I don’t take it for a day. I don’t really take it every day anyway. In my opinion, supplements and drugs should be used as tools as needed, not every day on a schedule. We should be assisting our bodies, not adding to its load.

The best quercetin supplement that I’ve tried is this one here on Amazon. Check out the price it’s at because sometimes it’s on a good sale. I really like this one because it incorporates bromelain into its ingredients, which is an allergy enzyme. It helps to break down allergy chemicals like histamine and leukotrienes that linger in your bloodstream and cause inflammation. That is, of course, on top of all of the benefits that quercetin provides alone.

  1. If you have burning mouth, you should have your zinc/copper levels tested.
    Or just try taking some Zinc and see if it helps.

      Perhaps you are taking too much of the quercetin because for some people it can be a little bit stimulating. I’m sure that younger people would enjoy that effect though. But I believe that the shakiness will go away with time because it did for me. Keep in touch with me!
