Quercetin Zinc And Synergy With Vitamin C

Although quercetin has some direct effects that protect against viral infection, its major effect maybe by acting as what is known as an ionophore in aiding the transport of free, unbound zinc into cells.

In its free, ionic state zinc can inhibit the replication of many viruses. When many viruses infect a cell, it inserts a piece of its genetic code and an enzyme called replicase to allow the virus to replicate. Zinc is able to block the replicase enzyme and, therefore, block the replication or spread of the virus. That is one of the reasons zinc is a popular recommendation against the common cold.

In order for zinc to have this effect on viral replicase, however, it is dependent upon an open ionophore – a special cell membrane channel that allows for an ion to enter the cell. Quercetin can act as a zinc ionophore to increase the levels of ionic zinc within cells to protect against viral replication. This effect of quercetin may explain the decreased number of respiratory tract infections noted in the studies described above.5

Another partner nutrient for quercetin is vitamin C. When vitamin C and quercetin are combined in test tube studies, their immune-enhancing and antiviral actions work synergistically to produce better results than when either is added alone.6

In addition to eating high vitamin C containing foods on a regular basis supplementing with additional vitamin C is also recommended .

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.

The Healing Effects Of Taking Quercetin And Vitamin C

Your body needs nutrients from your environment, specifically, through your diet, for it to function normally and keep itself safe from potential threats, such as a disease.

Quercetin, although not as well-known as most antioxidants, is a natural chemical you can obtain from eating plants. It can do wonders for your body, especially when supported with vitamin C.

Vitamin C, which is otherwise known as ascorbic acid, is a powerful antioxidant found in most fruits and vegetables. It is considered a natural shield against various diseases since it helps boost your immune system and protect our cells from oxidative damage.

What Is A Liposome

Liposomes are cells composed of two layers of fatty molecules that protect an inner compartment composed of water and water-soluble active ingredients. The water-soluble ingredient, like vitamin C for example, is protected within the inner compartment by the liposomal structure.

Liposomes of quercetin are not possible because quercetin is not water-soluble, but that turns out to make quercetin a perfect candidate for the use of technology that creates the LipoMicel Matrix.

Antioxidants Vs Free Radicals

In order to understand how taking a quercetin supplement may be beneficial to your health, its important to understand how antioxidants work.

Free radicals are molecules that can damage cells, potentially leading to numerous diseases, including cancer and heart disease. They form in the body as a result of the metabolic process, primarily when poor diets that consist of trans fats, processed foods, and excessive amounts of sugar are consumed. Environmental factors can also cause free radicals to develop, such as exposure to pollution, radiation, cigarette smoke, and various chemicals. A high level of free radicals in the body can lead to a process called oxidative stress, which in turn can lead to inflammation and various symptoms, ailments, and diseases.

One of the jobs of antioxidants is to tackle free radicals and reduce or eliminate their ability to cause cell damage. Antioxidants are found in numerous types of healthful foods, such as fruits, vegetables, grains, and seeds. They are also available in high concentrations in dietary supplements like quercetin.

May Improve Energy And Endurance

Quercetin is added to some athletic supplements because its believed to help increase athletic performance and endurance, likely because of its positive effects on blood flow. Researchers from the School of Applied Physiology at the Georgia Institute of Technology found that, on average, quercetin provides a statistically significant benefit in human endurance exercise capacity and endurance exercise performance.

Other studies show that quercetin helps increase immune function and prevents susceptibility to illnesses that can occur when someone trains intensely and experiences exhaustion. One study found evidence that taking a dosage of 500 mg of quercetin twice daily helped protect cyclers from exercise-induced respiratory infections.

Because it can boost energy, quercetin could affect sleep patterns. One study found evidence that it may alter the sleep-wake cycle partly through activation of GABA receptors. However, insomnia is generally not believed to be a common side effect of taking quercetin.

Immune Health Supplement Update: Quercetin And Vitamin C

An article was recently published in the June 19, 2020 journal Frontiers in Immunology entitled: Quercetin and Vitamin C: An Experimental, Synergistic Therapy for the Prevention and Treatment of SARS-CoV-2 Related Disease . The article states, Quercetin is a well-known flavonoid whose antiviral properties have been investigated in numerous studies. There is evidence vitamin C and quercetin co-administration exerts a synergistic antiviral action due to overlapping antiviral and immunomodulatory properties. Also, the ability of vitamin C to recycle and enhance the benefits of quercetin.

Helps In Preventing Inflammation And Allergies

Quercetin has also been shown to be anti-inflammatory and to directly help prevent incorrect immune responses like those involved in autoimmune conditions and allergies. In fact, supplementation with quercetin has been shown to stabilize certain immune cells, called mast cells, to prevent their release of histamine. Mast cells release histamine when they come into contact with an allergen. Histamine triggers other immune cells to migrate to the area so that the body mounts an immune response. It is this immune response that is responsible for allergic symptoms such as runny nose and itchy watery eyes. By preventing histamine release, quercetin can help to prevent environmental and skin allergies. For more information on this effect, please see our Autoimmune Disease and Allergy articles.

It Protects Against Allergies

Quercetin inhibits the release of histamines thereby making it effective against common symptoms of itching, watery eyes, and hives. Aside from this, it can also be taken ahead of exposure as a means of preventing allergies. This chemical is also being studied as a possible treatment against anaphylactic reactions.

Plus, quercetin has the ability to suppress leukocytes in both the lungs and bloodstream leading to a relaxed airway passage and more elastic lung tissue. Due to these, quercetin is considered to be a potential treatment for asthma, which is usually triggered alongside allergies.

Beneficial Effects Of Vitamin C And Quercetin In Viral Infections

There is a tremendous amount of literature supporting the antiviral properties of quercetin, in both in vitro and in vivo experiments. Quercetin inhibits several respiratory viruses in cultured cells . It inhibits the cytopathic effects provoked by many serotypes of rhinovirus, echovirus , coxsackievirus , and poliovirus at a minimal inhibitory concentration of 0.03 to 0.5 g/ml in Hela or WI-38 cells . Quercetin also significantly reduces plaque formation by RNA and DNA viruses displaying anti-infective and anti-replicative properties . It inhibits the replication of cytomegalovirus inoculated HeLa cells at a half inhibitory concentration of 3.2 ± 0.8 M and with a selectivity index of 22 . Dengue virus type 2 replication in Vero cells is inhibited by quercetin at an IC50 of 35.7 g/mL, causing a DENV-2 RNA reduction of 67%. This is attributed to quercetin’s ability to either block virus entry or inhibit viral replication enzymes such as viral polymerases .

The only human study of vitamin C has been in USSR soldiers with severe viral infection indicated vitamin C supplementation protected from influenza-associated pneumonia and was associated with shorter hospital stays .
