Why use Quercetin Plus? 

Your Wellbeing QUERCETIN PLUS is used to alleviate allergies and assist in the prevention of upper respiratory, skin, urinary and other infections. This compound, blended with bromelain, nettle root and olive leaf extract, completes the synergy for immune system support. It is also used for its antioxidant properties.

Quercetin and its health benefits

Quercetin is a natural yellow pigment that belongs to a group of plant compounds called flavonoids. These compounds are rich in antioxidant activity and exhibit anti-inflammatory, anti-allergic and anti-oxidant effects.

Antioxidants mop up and neutralize free radicals inside the body. These unstable molecules can cause damage to the cells when their levels are too high resulting in serious conditions like cancer and diabetes.

Quercetin is the most abundant flavonoid in a healthy diet and is readily available in foods like apples, grapes, cherries, red onions, cocoa, blueberries, green tea, tomatoes and kale.

Foods containing quercetin can help manage several inflammatory health issues. It is important to keep inflammation under control as chronic inflammation can eventually lead to damaged cells, tissue and organs. Over time, this can lead to chronic conditions like cancer, rheumatoid arthritis, autoimmune disorders, allergies and heart disease.

The causes of chronic inflammation are stress; viral and bacterial pathogens; foods like sugar and refined carbohydrates; long term exposure to irritants like pollution; smoking, high blood insulin levels, obesity and auto-immune response. 

Quercetin is the most well-researched antioxidant and the numerous studies done on this flavonoid have yielded some impressive results.

Quercetin and Allergies

Studies have shown that Quercetin acts to stabilize cells in the body that release histamine — the chemical that triggers immune cells to secrete mucus in the sinuses. (Trusted Source 1)

This natural antihistamine can relieve the symptoms of asthma and the effects of seasonal allergies that cause symptoms like coughing, sneezing, runny noses, itching and watery eyes.

Quercetin has been used for centuries in herbal formulas to control food allergies and to provide relief from skin conditions like eczema and hives.

For even stronger anti-inflammatory effects, take Quercetin as a supplement. It is safe to take as a supplement with little to no side effects. Doses exceeding 1000IU a day could result in headaches and tingling in the arms.

Helps Fight Pain

Studies have shown a correlation between quercetin and inflammatory pain. There is evidence that subjects experiencing bladder pains from infections have fewer symptoms when taking quercetin supplements. (Trusted Source 2)

It is also linked to pain alleviation of prostatitis (inflammation of the prostate) (Trusted Source 3) and rheumatoid arthritis.

In one study conducted over 8 weeks, 50 female participants with rheumatoid arthritis took 500 mg of quercetin a day. They experienced significantly reduced early-morning stiffness, morning pain, and after-activity pain. (Trusted Source 4)

Heart Health

Numerous studies have been conducted to test the effects of quercetin on heart and blood vessel-related disorders. Due to its ability to lower inflammation and oxidative stress, quercetin seems to be beneficial for people with certain cardiovascular risk factors. (Trusted Source 5)

Research studies also show that people who have a diet rich in antioxidants have fewer incidences of high blood pressure and hypertension.

Energy and Endurance

In a 2013 study involving 60 male students who had participated in athletics for at least three years, the results showed that they had improved their lean body mass, their total body water and basal metabolic rate, and their total energy expenditure after taking quercetin. (Trusted Source 6)

A 2019 study showed increased endurance in untrained participants after only 7 days on a 500mg twice-daily regimen. (Trusted Source 7)

Antioxidants have shown to improve the health of blood vessels that carry oxygen and nutrients to muscle and joint tissue. This positive effect on blood flow may be the reason for the boost in athletic performance.

Cancer

Research has indicated that Quercetin has the potential to prevent and treat certain cancers. It appears to have the ability to induce cancer cell apoptosis (cell death) without affecting non-cancerous cells.

The study also concluded that Quercetin in combination with chemotherapy and radiation acts as a sensitizer and protects healthy cells from side effects of these cancer therapies. (Trusted Source 8)

If you have cancer, consult with a specialist before you supplement with Quercetin. Quercetin supplementation may not offer protection against estrogen-fuelled breast cancer and may exacerbate tumour growth.

Neurological Disorders

Quercetin can protect the brain against inflammation and oxidative stress, factors that result in neurological conditions like Alzheimer's disease and dementia.

A 2018 study concluded that dietary flavonoids, like quercetin, can boost protection from cognitive dysfunction related to neuron destruction. (Trusted Source 9)

Bromelain

Bromelain is a natural anti-inflammatory derived mainly from the stem of pineapples. For centuries, South and Central Americans used pineapple to treat indigestion, swelling and inflammation.

Studies have shown that bromelain can reduce swelling after surgery and in the treatment of inflammation, particularly for chronic inflammation of the nose and sinuses. (Trusted Source 10)

Combining Quercetin with Bromelain enhances the anti-inflammatory properties of both compounds. Bromelain is also usually blended together with Quercetin to increase its absorption into the bloodstream.

This powerful blend of compounds with antihistamine and anti-inflammatory properties may be especially helpful in relieving eczema, hay fever and other allergies.

Nettle Leaf

Nettle Leaf has been used in traditional medicine for thousands of years. Early Greek physicians administered nettle leaf infusions for ailments from arthritis to lower back pain.

It also has a long history of use as a herbal remedy to modulate respiratory pathways and alleviate upper respiratory infections.

Studies show that taking a nettle leaf supplement may help to reduce hay fever symptoms and reduce blood pressure, blood sugar levels and inflammation. (Trusted Source 11)

Research suggests that the anti-inflammatory actions of nettle leaf are caused by the ability of the nettle to prevent the production of inflammatory chemicals known as prostaglandins.

If you are pregnant or taking medications like blood thinners, diuretics or lithium; or you are on medication for blood pressure or diabetes please consult with your doctor before consuming a nettle leaf supplement.


Olive leaf

Olive leaf extract has been used as plant medicine throughout the ages. It was used to treat a variety of ailments including malaria and as a general tonic to strengthen the immune system. Today, research indicates that olive leaf extract has strong antimicrobial, anti-inflammatory and antioxidant qualities.

The bitter substances in olive leaves are polyphenols. Polyphenols are organic chemicals that occur in plants. They protect the body against oxidative stress that can lead to chronic illnesses and inflammation. Polyphenols are particularly helpful in protecting cells against bacterial and viral damage.

Olive leaf contains as many as 50 different polyphenols including the main phenolic compound called oleuropein, and its metabolite hydroxytyrosol - which have powerful antioxidant, anti-inflammatory and disease-fighting properties.

Laboratory studies found that oleuropein may be effective against numerous disease-causing microbes including viruses that cause influenza and similar respiratory infections. The research suggests that oleuropein can also lower blood pressure and protect the heart and brain from degenerative diseases. (Trusted Source 12)


In summary

QUERCETIN PLUS is a proprietary blend of ingredients that work synergistically to enhance the effect of quercetin. 

Take this supplement to strengthen immunity, fight inflammation, resist allergies, boost exercise performance, and maintain general health.
