iv. Does Quercetin Help Allergies? : Research Studies

Quercetin has been shown to reduce inflammation in multiple studies. In this 8 week study involving 50 women with rheumatoid arthritis, participants took 500mg of quercetin per day or a placebo. The quercetin group reported less early morning stiffness, morning pain, and after-activity pain. Early studies on quercetin and inflammation are promising, although more large scale human studies need to be performed to verify these benefits.Theres evidence that quercetin reduces allergy symptoms. Researchers believe quercetins anti-inflammatory effects may relieve allergy symptoms.This study , for example, found that quercetin could be effective for treating the anaphylactic reaction in someone with peanut allergies. A similar study from 2006 concluded that quercetin was a safe, natural therapy that may be used as primary therapy or in conjunction with conventional methods for blocking allergies. Its possible that quercetin has the same anti-allergy effect in humans, although more research needs to be done.

Dental Hygiene And Cold Sores

As the virus that causes herpes is carried in saliva, some extra dental hygiene precautions may be vital to avoid reinfecting yourself after an outbreak.

Keep your toothbrush in a dry place, on an open shelf where it’s exposed to circulating air or sunlight. A wet toothbrush in a moist bathroom is an invitation for viruses to breed.

Buy a small tube of toothpaste, use it during the outbreak, then throw it away.

Replace your toothbrush after an outbreak, and regularly in between times.

What Is Quercetin Used For

Quercetin is an antioxidant, which means it neutralizes free radicalsthe chemical byproducts that harm cell membranes and damage DNA. In alternative medicine, quercetin is said to help with the following conditions:

So far, results to support the benefits of quercetin are mixed. Furthermore, its use for some conditions has only been examined in test tube or animal studiesthe results of which can not automatically be assumed to apply to humans.

If you’re considering using it, consult your primary care provider first. Self-treating a condition and avoiding or delaying standard care may have serious consequences.

Here’s a look at some research highlights.

What Is An Ionophore

An ionophore is an ion carrier a molecule that facilitates the movement of electronically charged ions in and out of cell membranes. Ionophores are lipid-soluble and are typically biosynthesized by microorganisms. Their mechanism of transfer involves reversibly binding to ions and releasing them on one or the other side of a cell membrane.

There are two types of ionophores worth noting:

#1 Carrier ionophores

Carrier ionophores bind to an electrically charged ion and protect its charge while it is carried through the cell membrane. These can be proteins or a wide range of other lipid-soluble molecules with properties that are capable of reversibly binding to an ion.

#2 Channel ionophores

Ionophores can form ion channels through the membrane, allowing the passage of a variety of ions that would otherwise not have been able to enter or exit the cell. These ion channels can thus be regulated and controlled. Examples of endogenous ion channels include lithium , calcium , magnesium , and potassium but there are many others.

In industry, ionophores are especially of interest in the development of antibiotics and other pharmaceuticals.

For example, antibiotics may have difficulty entering into cells if they are hydrophobic. Thus, pharmaceutical development often needs to make use of endogenous ionophores to facilitate the antibiotic entering through the cell membrane.

How Much Quercetin Should I Take

In general, you probably get the right amount of quercetin from the food you eat, especially if you have plant-based foods into your diets. However, evidence shows that quercetin supplements can help with inflammation, allergy symptoms, immune response, and more.

Typical dosages range from 5001,000 mg per day. Evidence suggests that it is safe to take as a supplement, though taking more than the highest recommended dosage may lead to side effects like headaches or stomach aches.

You should check with your doctor before you introduce quercetin into your wellness routine it can interact with other medications and produce side effects. Because bodies dont easily absorb quercetin, supplements are often compounded with other ingredients to help absorption.

Quercetin is a pigment that belongs to a group of plant compounds called flavonoids.

Flavonoids are present in:

Theyve been linked to several health benefits, including reduced risks of heart disease, cancer, and degenerative brain disorders .

The beneficial effects of flavonoids like quercetin come from their ability to function as antioxidants inside your body .

Antioxidants are compounds that can bind to and neutralize free radicals.

Free radicals are unstable molecules that may cause cellular damage when their levels become too high.

Damage caused by free radicals has been linked to numerous chronic conditions, including cancer, heart disease, and diabetes .

Quercetin is the most abundant flavonoid in the diet. Its estimated that the average person consumes 10100 mg of it daily through various food sources .

Foods that commonly contain quercetin include onions, apples, grapes, berries, broccoli, citrus fruits, cherries, green tea, coffee, red wine, and capers (

Does Quercetin Protect Against Covid

There is not enough evidence to show that quercetin can prevent or treat COVID-19. However, recent studies have shown that it may prevent COVID-19 from replicating within the body, helping to fight infection and lessen symptoms.

In a recent study, researchers looked at plant-based chemicals to see if treatments for COVID-19 might be found in drugs were already using. Quercetin was identified as a top contender, and it has the potential to significantly interfere with a SARS-CoV-2 infection. It may bind to COVID-19 cells, preventing them from infecting host cells and spreading the virus further throughout the body.

Clinical trials must be done before there is evidence that a patient could receive quercetin as a treatment for a COVID-19 infection.

If You Have Symptoms Find Out What Youre Dealing With

With genital herpes, the biggest mistake people make is not seeking medical advice, says Gade.

People often find the signs or symptoms of a first herpes outbreak confusing, says Gade. You may mistake herpes symptoms for those of a yeast infection and try curing that condition on your own. But if your healthcare provider diagnoses you with herpes, the first line of treatment will be antiviral medications.

, you can make matters worse by putting things on the herpes sores that you shouldnt put on the sores, she says. People often try using Vaseline, bacitracin, or Aquaphor to soothe the itchy or painful eruptions.

Honestly, not putting anything on the sores is best, says Gade. Do keep the area clean and dry, though.

Warm compresses applied to tender or painful areas can help. So can sitting in a warm bath, using Epsom salt.

Sometimes people have enormous pain with urination, says Gade. For relief, you can urinate in your bathwater or while taking a shower to dilute the urine stream and lessen the sensation. You can also use warm water in a spray bottle to dilute the stream while youre urinating.

How Zinc And Quercetin Work Together

We are all familiar with zinc as an essential mineral for a strong immune system. Although zinc has many benefits, in order for it to get into the cells where it can be utilized most effectively, it needs assistance from substances called ionophores.

Ionophores are fat-soluble molecules that bind to ions to help move them across cell membranes. Without the right ionophore, elemental zinc is poorly absorbed and will remain stuck in the bloodstream where it cannot be used by the bodys cells.

Many substances can act as ionophores for zinc, one being the antioxidant quercetin. Thus, taking quercetin along with zinc may provide additional benefits to an immune-boosting protocol.

Zinc Deficiency During Illness

Zinc is the structural element of many molecules that play a role in immunity. It also helps regulate antioxidant balance, reducing oxidative stress within the cell. This important trace element also has extensive antimicrobial activity within the cell. It can act upon a variety of different viruses, helping the body effectively fight them off.

During times of illness, since zinc plays such an important role in immune function, the body uses up its current stores of zinc, leading to zinc depletion.

A zinc deficiency may result in increasedinflammation and oxidative stress, making it more difficult to fight off the original illness. Many of the complications related to severe illness are exacerbated by zinc deficiency.

Foods high in zinc include:

Quercetin

Side Effects Of Taking Quercetin

Quercetin is present in many healthy foods, and eating a variety of the quercetin-rich foods listed above poses no risk . Supplements are quite safe too. “I have found that quercetin is very well tolerated with minimal side effects, the most common of which is mild upset stomach,” says Rountree.

Some research suggests16 that quercetin may cause headaches or tingling nerve sensations, but Rountree says he has not seen this among his patients and that quercetin is on his “A-list of supplements” that most people could benefit from taking every day.

Who should avoid quercetin? If you’re currently taking another medication, it’s always a good idea to talk to your health care provider about potential interactions. For example, because quercetin can thin the blood and help reduce blood clots, it may interfere or amplify the effects of blood thinners there’s also some evidence it could interfere with medications that have a narrow therapeutic window such as transplant anti-rejection drugs.

Pregnant women should also steer clear since no good studies exist on the safety of quercetin during pregnancy .

How To Take Quercetin And Dosage

Most people will realistically only hit up to 80 mg of quercetin per day from dietary sources, according to Rountree. So supplements are necessary if you want to fight allergies, support immunity, or experience any of the potential quercetin health benefits listed above. In fact, “the dose for prevention of allergic symptoms is from 500 to 3,000 mg daily,” he says.

A typical dose of quercetin is 500 to 1,000 mg per day . However, quercetin is somewhat poorly absorbed through the intestinal wall, so Rountree recommends quercetin phytosomea form where quercetin is attached to a phospholipid complex18, which has been shown to dramatically enhance absorption19.

Another way to get more nutritional bang for your quercetin buck: Combine it with vitamin C. “I recommend a form of quercetin with a food-derived vitamin C source like acerola cherry and bioflavonoids from citrus,” says Miller. “This will provide some synergistic effects, which will get outcomes at a lower dosage.”

Inhibition Of Reverse Transcriptase

Quercetin has been investigated in vitro as an antiviral agent for HIV due to its ability to inhibit crucial enzymes: reverse transcriptase , integrase , and protease . Quercetin significantly reduces HIV viral replication and, when added to peripheral blood mononuclear cells infected with HIV and compared to HIV infected controls, quercetin reduced the levels of p24, Long Terminal Repeat gene expression, and viral infectivity together with an inhibition of TNF- and upregulation of IL-13 .

Quercetin has also been shown to inhibit non-HIV RT activity in vitro, including avian myeloblastosis reverse transcriptase , Rous-associated virus-2 , and Maloney murine leukemia virus . Quercetin displayed a dose-dependent inhibitory action: at 50 M, 23% inhibition of both AMV-RT and RAV-2-RT, and at 10 M inhibition of mammalian MMLV-RT of almost 60% were reached . HIV-RT was inhibited completely at 2 g/ml quercetin in a partially-competitive mode . These antiviral effects of quercetin are believed to be related to the five hydroxyl groups on 3, 3, 4, 5, and 7 as the inhibitory activity is lower for baicalein, quercetagetin, or luteolin which lack these groups .

Interestingly, Harakeh et al. studied the dose-dependent effect of ascorbic acid on HIV-infected T-lymphocytes in vitro and reported that > 99% reverse transcriptase and nearly > 90% p24 antigen suppression and a 93% inhibition of syncytia formation, a marker that correlates with viral infectivity and cytopathic effects .

Possible Quercetin Side Effects

Quercetin is generally well-tolerated when used in appropriate amounts. Some possible side effects of quercetin include:

• Tingling in the arms and legs

Very high dosesgreater than 1 gram per daymight cause kidney damage. Some studies have also found that quercetin may interfere with thyroid function.

Avoid taking quercetin if you’re pregnant, nursing, or have a kidney condition. It may also interfere with some antibiotics or blood thinners.

Check with your doctor before using a quercetin supplement. Be sure to mention any medications you are taking and any conditions you have.

Interfering With Dna And Rna Polymerases

The in vitro antiviral effects of quercetin on herpesviruses and adenoviruses suggest inhibition of early stage viral replication in a dose dependent manner , as well as inhibition of viral DNA and RNA polymerase . In human embryonic kidney cells , inoculated with polio, 3-methyl-quercetin disrupted plaque formation while quercetin itself demonstrated these effects when administered together with vitamin C . In fact, Vitamin C , prevented quercetin spontaneous degradation suggesting necessary co-administration with ascorbate to exert its antiviral effect. The beneficial effects of 3-methyl-quercetin were exerted primarily when the compound was administered 12 h post-poliovirus infection in Hela cells, inhibiting viral proteins and RNA synthesis in a dose dependent manner . In fact, 3-methyl-quercetin was identified as a molecule able to bind essential proteins required during the transcription from minus-strand RNA into positive polarity RNAs, thus interfering with cytoplasmic viral RNA replication .
