Quercetin 500mg Quercetin 500mg

Optimized Quercetin is a dietary supplement consisting of quercetin, a chemical substance of plant origin, classified as a flavone. It is characterized by a very high biological activity and is one of the flavonoids most widely used in pharmacy. It has anti-inflammatory and anti-allergic properties. It protects the body system from oxidative stress and neutralizes the harmful effects of free radicals.

Quercetin shows immunomodulatory properties, and that is why it is recommended for people with low immunity. Clinical studies have confirmed its participation in the regulation of many cellular processes, which can be used in cancer therapy.

Vitamin C contained in the product should strengthen its action. Synergistic action of quercetin and vitamin C has been confirmed scientifically. The combination of the two compounds is characterized by a such broad spectrum of health promoting properties, that such combination has been even patented in some parts of the world and approved as a prescription drug.

Quercetin (3, 5, 7, 3', 4'-pentahydroxyflavone) is one of the main flavonoids from the flavonols group. It is naturally present in many plants, fruits and vegetables; its large quantities can be found in onions, apples, green tea, strawberries or cauliflowers.

Its structure is responsible for the unique biological properties of quercetin. The structure of quercetin molecule is flat, which facilitates reaching the interior of lipid bilayer and the protection against peroxidation of lipids. Antioxidant properties of quercetin are enhanced by the presence of double bind in the ring C. The presence of five hydroxyl groups in the quercetin molecule influences not only the antioxidant parameters, but also the ability to chelate metals.

Quercetin, ingested even in large quantities, is quickly metabolized and removed from the body system. To achieve the desired therapeutic effects, you need a significant increase in the concentration of quercetin in the serum, which can be provided only by a long-term supplementation.

Anti-inflammatory, anti-allergic and antioxidant properties
Chronic inflammation is often called "silent killer" because it is responsible for a number of diseases and accelerates ageing of the body system. Quercetin shows strong anti-inflammatory properties. It inhibits the activity of cyclooxygenase-2 (COX-2), the main enzyme responsible for inflammation. It also contributes to the reduction in the amount of various inflammatory mediators, including cytokines.

Inflammation may also appear as a result of allergic reactions. Quercetin inhibits enzymes responsible for production of prostaglandins and leukotrienes. Both leukotrienes and prostaglandins are strong inflammatory mediators, and leukotrienes are correlated usually with inflammation in allergic diseases.

Quercetin inhibits also the release of histamine, a substance responsible for the majority of allergic reactions. This reduces their severity and eliminates some of the unpleasant symptoms, e.g. hay fever and watery eyes. Laboratory tests proved that quercetin inhibits histamine with up to 96% efficiency!

Synergistic action of quercetin and vitamin C is the best protection against oxidative stress, which determines premature ageing and contributes to the formation of pathological changes in cells. One of the main functions of vitamin C is minimizing hazardous effects of oxidation.

Studies have demonstrated that quercetin, like other flavonoids, increases the concentration of vitamin C in the body system and improves its efficiency. Moreover, thanks to unique antioxidant properties, quercetin locates and neutralises the two most dangerous types of free radicals, peroxide and superoxide.

Prevention of cardiovascular diseases
Quercetin improves blood circulation and strengthens the walls of blood vessels, so it keeps the cardiovascular system in the proper condition. It protects against dangerous complications of diabetes, which can affect the cardiovascular system.

Diabetes contributes to increased activity of neutrophils, a type of white blood cells, which stick to the endothelium of blood vessels and lead to the arterial disease. The studies have shown that quercetin inhibits the activity of neutrophils in patients with type 2 diabetes, and thus protects the cardiovascular system from the harmful consequences of the disease.

Quercetin reduces lipid peroxidation which is a process leading to the development of atherosclerosis. It inhibits the oxidation of harmful low density lipoproteins (LDL) and reduces the formation of apoliprotein B, the main component of LDL. It also reduces the concentration of lipids in plasma and liver. Thus it improves the lipid profile and minimizes the risk of atherosclerosis and other cardiovascular diseases.

Support for immunity and anticancer properties
One of the main functions of quercetin in the body system is to strengthen the immune response to viruses, bacteria, allergens and carcinogenic substances. Quercetin can support the fight against a number of serious infections, and some scientists say that it is effective even in relation to the HIV virus. Studies have demonstrated that it selectively destroys cells infected by the virus. What is more, quercetin is an inhibitor of Vpr protein activity which is necessary for viruses to copy its genetic material and spread over the body system.

Quercetin was investigated for anticancer properties, and the results of these tests are very promising. It has been proven that this substance inhibits the proliferation of cancer cells and affects the growth of mutant cells apoptosis.

Optimized Quercetin is a product with a broad spectrum of health promoting and therapeutic properties. It contains substances of natural origin, whose effectiveness has been scientifically proven. It can be used in the treatment of cardiovascular diseases and to eliminate inflammations and allergies. It is an excellent element of prevention of cancer and diseases related to the weakening of immunity. Regular supplementation delays ageing processes of the body system and protects against many diseases related to chronic inflammations and oxidative stress.
