Jarrow Formulas Quercetin is a dietary supplement which contains quercetin, a natural chemical compound of plant origin. It shows antihistamine, anti-inflammatory and antioxidant properties.

Thanks to the strong antiviral effects, quercetin relieves the immune system and improves its functions. Moreover, it improves the condition of blood vessels and promotes the regulation of lipid profile. Used preventively, it prevents cardiovascular diseases and minimizes the risk of strokes and infarctions.

The product is recommended within the general preventive healthcare. It is extremely useful for people who are exposed to high risk of atherosclerosis and cardiovascular diseases. The supplementation will be also beneficial for allergics. The product is a valuable support for the body system in the period of pollen and in flu and cold season.

Quercetin (3,5,7,3’,4’-pentahydroxyflavone) is a chemical compound from the flavonoids group. It is naturally present in many plants, vegetables and fruits (onion, green tea, chokeberry, apple, cauliflower and brussels sprouts). Quercetin is metabolized quickly and does not accumulate in the body system. To achieve therapeutic effects, there is a need of a significant increase in its concentration in the blood serum, which is possible to achieve only with the regular supplementation.

The specific, flat structure of a quercetin molecule, which allows for the penetration into the lipid bilayer, the double bond in ring C and five hydroxyl groups are responsible for the biological activity of the compound and its pharmacological properties.

Anti-inflammatory properties
Quercetin effectively suppresses inflammations in the body system and prevents disease caused by them. It reduces the amounts of different inflammatory cytokines and is a strong inhibitor of enzymes responsible for inflammation development (e.g. cyclooxygenase-2). Moreover, it modulates the activity of a key anti-inflammatory factor, which is NF-kappa B.

The clinical studies on the possible use of quercetin in the treatment of rheumatoid arthritis have proven its effectiveness in inhibiting inflammations. This resulted in a significant reduction in pain, improvement in the range of movements and beneficial changes in the synovial fluid of joints in all people tested.

Antioxidant potential
Quercetin is characterised by a unique antioxidant activity. It scavenges the excess of the most dangerous peroxide radicals from the body system and protects cells from damage caused by their activity and oxidative stress.

Moreover, quercetin positively influences other antioxidants. It stimulates the core stage leading to glutathione production, which is the main cellular antioxidant. It shows synergy of action with vitamin C; it improves its activity and raises its level in the body system.

Anti-allergic properties
Quercetin acts as a natural anti-allergic agent and can alleviate the unwelcome symptoms of allergies, such as hay fever, tearing eyes, sneezing and problems with breathing. It stabilizes mast cells responsible for the release of histamine and other inflammation mediators associated with allergic reactions. In clinical studies, quercetin reached 96% effectiveness in inhibiting histamine!

Prevention of cardiovascular diseases
Quercetin supports the cardiovascular system and prevents its disorders in different ways. It reduces blood pressure in people with hypertension. In the randomized double crossover study, it has been proven that, after 28 days of regular supplementation with quercetin, the blood pressure in people without disorders did not change, while in patients suffering from hypertension the researchers observed a reduction in both systolic and diastolic pressure.

Quercetin takes care of the health of blood vessels. It improves the functions of endothelium and modulates the production of endothelin 1, a peptide contributing to vasoconstriction. Moreover, it thins the blood and prevents platelets aggregation, which can lead to dangerous clots.

Quercetin helps to regulate lipid profile and improves the relationship between HDL and LDL fractions. It inhibits the synthesis of apolipoprotein B, the main building element for low density lipoprotein (or “bad” LDL cholesterol). It contributes to the reduction in lipids concentration in liver and plasma. It reduces lipid peroxidation, which is an important element of atherosclerosis pathophysiology.

Antiviral properties
Quercetin affects different kinds of viral infections by reducing their ability to spread in the body system. It has anti-influenza properties; thanks to the direct influence on the influenza virus components it inhibits its replication. Moreover, it interferes with gene signals which allow for the production of the virus responsible for hepatitis C. It selectively destroys the cells infected by HIV.

Quercetin for athletes
There are studies indicating the positive influence of quercetin on the improvement in endurance and productivity, which can be of great importance for sports results. It is believed that quercetin contributes to the increase in the number of intracellular mitochondria. This has a positive influence on the increased aerobic activity and increase in the maximal oxygen consumption (VO2 max).

Anticancer activity
Quercetin shows anticancer potential. It not only prevents the development of cancer cells thanks to the antioxidant and anti-inflammatory properties, but also stimulates apoptosis of mutated cells and limits proliferation.

To sum it all up, Quercetin is a supplement of very beneficial influence on the human body system. The plant origin of the active substance makes it possible to use the product without the risk of negative side effects. The product supports the body system in different aspects and protects it from many diseases, including cancers.
