By combining Quercetin with ascorbic acid preparations, an increase in the effects can be observed. This is evidenced by numerous reviews of Quercetin.

the flavonoid quercetin is an aglycone of many plant flavonoid glycosides, including rutin, and belongs to vitamin preparations group R. Due to capillary stabilizing properties associated with antioxidant, membrane stabilizing effects, the drug reduces capillary permeability. Quercetin has an anti-inflammatory effect as a result of blocking the lipoxygenase pathway of arachidonic acid metabolism, reduces the synthesis of leukotrienes, serotonin and other inflammatory mediators.
Quercetin exhibits anti-ulcer action associated with the use of anti-inflammatory drugs, and also has a radioprotective activity (after X-ray and gamma irradiation).
The cardioprotective properties of Quercetin are due to an increase in the energy supply of cardiomyocytes due to its antioxidant effect and an improvement in blood circulation.
The regenerative properties of Quercetin are manifested in accelerated wound healing. The drug can affect the processes of bone tissue remodeling; it exhibits persistent immunomodulatory activity.
Diuretic, antispasmodic, antisclerotic properties were also experimentally determined. Quercetin is able to normalize blood pressure and stimulate the release of insulin, accelerate platelet aggregation, and inhibit thromboxane synthesis.
Quercetin also binds to estrogen receptors. Due to estrogen-like properties (influence on proline hydroxylase, inhibition of tumor necrosis factor and synthesis of interleukins), the drug has a proosteoclastic effect.
After oral administration, the drug is well absorbed. Further pharmacokinetics of the drug have not been studied.

Pharmacological properties

Pharmacodynamics... The flavonoid quercetin is aglycone (Aglycon - a non-carbohydrate fragment of glycosides. Aglycone in most cases determines the biological activity of glycosides (pharmacodynamic properties)) many plant flavonoid glycosides (Glycosides - organic substances, the molecules of which consist of a carbohydrate and a non-carbohydrate component (aglycone). Widespread in plants, where they can be a form of transport and storage of various substances), including rutin, and belongs to group P vitamin preparations. Due to the capillary-stabilizing properties associated with antioxidant, membrane-stabilizing effects, the drug reduces permeability capillaries (Capillaries - the smallest vessels that penetrate organs and tissues. Connect arterioles with venules (the smallest veins) and close the circle of blood circulation)... Quercetin has anti-inflammatory effects as a result blockades (Blockade - slowing down or interruption of electrical impulses in any part of the conducting system of the heart or myocardium) lipoxygenase pathway metabolism (Metabolism - the totality of all types of transformations of substances and energy in the body, ensuring its development, vital activity and self-reproduction, as well as its connection with the environment and adaptation to changes in external conditions) arachidonic acid, reduces the synthesis of leukotrienes, serotonin (Serotonin - a derivative of the amino acid tryptophan. Synthesized primarily in the central nervous system and chromaffin cells gastrointestinal tract... Conduction mediator nerve impulse through the synapse. Vertebrate brain neurons that use serotonin as a mediator are involved in the regulation of many forms of behavior, sleep processes, thermoregulation, etc. As a hormone, serotonin also regulates gastrointestinal tract motility, mucus secretion, causes spasm of damaged vessels, etc. ) and others mediators (Mediator - a substance that transfers excitation from a nerve ending to a working organ and from one nerve cell to another) inflammation.
Quercetin exhibits antiulcerogenic action associated with the use of anti-inflammatory drugs, and also has a radioprotective activity (after X-ray and gamma irradiation).
The cardioprotective properties of Quercetin are due to an increase in the energy supply of cardiomyocytes due to its antioxidant effect and an improvement in blood circulation.
The regenerative properties of Quercetin are manifested in accelerated wound healing. The drug can affect the processes of bone tissue remodeling; it exhibits persistent immunomodulatory activity.
Diuretic, antispasmodic, antisclerotic properties were also experimentally determined. Quercetin is able to normalize blood pressure and stimulate the release of insulin, accelerate aggregation (Aggregation (attachment) - the process of combining elements into one system) platelets (Platelets - blood cells involved in the process of blood clotting. With a decrease in their number - thrombocytopenia - there is a tendency to bleeding), inhibit the synthesis of thromboxane.
Quercetin also binds to receptors (Receptor (Latin receptio - perception, English receptor): 1) specific sensitive formations in living organisms that perceive external and internal stimuli (extero- and interoreceptors, respectively) and transform activity nervous system... Depending on the type of perceived irritation, mechanoreceptors, chemoreceptors, photoreceptors, electroreceptors, thermoreceptors are distinguished; 2) active groups of protein macromolecules with which mediators or hormones specifically interact, as well as many drugs. A receptor is a conformationally flexible macromolecule or a set of macromolecules, binding to which (s) a ligand (agonist or antagonist) causes a biological or pharmacological effects... A number of receptors exist in several subtypes. There are four main types of receptors: 1) membrane receptors associated with ion channels and consisting of several protein subunits, which are located in biological membranes of cells in a radial order, forming ion channels (for example, H-cholinergic receptors, GABA A-receptors, glutamate receptors ) \\; 2) membrane receptors conjugated with G-proteins, consisting of protein molecules, sevenfold "stitching" biological membranes; biological effect when these receptors are activated, it develops with the participation of a system of secondary transmitters (Ca2 + ions, cAMP, inositol-1,4,5-triphosphate, diacylglycerol). Receptors of this type are available for a number of hormones and mediators (for example, M-cholinergic receptors, adrenergic receptors, etc.) \\; 3) intracellular, or nuclear receptors that regulate the processes of DNA transcription and, accordingly, the synthesis of proteins by cells. They are cytosolic and nuclear proteins (for example, receptors for steroid and thyroid hormones) \\; 4) membrane receptors that directly control the functions of the effector enzyme associated with tyrosine kinase and regulate the phosphorylation of proteins (for example, insulin receptors, a number of growth factors, etc.)) estrogen (Estrogen - the pituitary hormone responsible for the maturation of eggs)... Due to estrogen-like properties, (effect on proline hydroxylase, inhibition of tumor necrosis factor and synthesis interleukins (Interleukins - one of the groups of cytokines, are polypeptide mediators involved in the formation and regulation of local defense reactions organism)) the drug has proosteoclastic effects.

Pharmacokinetics... Not studied. The drug is well absorbed.
