Immune Support C Extra + Quercetin Bioflavonoids is a natural formula that supports the prevention and treatment of viral and bacterial infections.

Immune Support C Extra + Quercetin Bioflavonoids contains vitamin C and the antioxidant quercetin, whose immunostimulating, antimicrobial, anti-inflammatory and anti-allergic properties have been documented in numerous studies.

The combination of quercetin and vitamin C exhibits a powerful immunostimulating and antiviral effect against a wide range of respiratory infections.

Benefits of Vitamin C

A water-soluble vitamin, also known as ascorbic acid. It plays a vital role in maintaining immune status and stimulating recovery in the presence of an infectious disease with a developed clinical picture.

How it exerts its immunomodulatory effects: by enhancing lymphocyte activity, increasing interferon-alpha production, modulating cytokines, reducing inflammation, correcting endothelial dysfunction, and restoring mitochondrial functions, including the generation of cellular energy.

It also helps in the formation of collagen – a protein necessary for the normal development and maintenance of bones, cartilage, teeth and gums.

Vitamin C is not stored in the body and must be consumed daily through diet or dietary supplements. The body's needs for vitamin C increase during mental and physical stress, intense physical activity, illness, and antibiotic treatment.

Quercetin Benefits

It is a plant polyphenol antioxidant (bioflavonoid) from the group of flavonols with anti-allergic, anti-inflammatory, immunostimulating and blood vessel-protective effects.

It is contained in many fruits, vegetables, and herbs, but the recommended daily doses of quercetin are difficult to obtain through diet alone.

It exhibits a wide range of effects, including:
strengthening general and anti-infectious immunity;
relief of allergy symptoms;
maintaining the health of the heart and blood vessels – arteries, veins and capillaries;
neutralizing free radicals (reactive oxygen and nitrogen species formed during metabolism) and reducing oxidative damage to cells and tissues

There is data from independent external studies that:
quercetin has shown antibacterial activity against Klebsiella pneumoniae, Staphylococcus aureus, Escherichia coli, Acinetobacter baumannii, Candida;
the antiviral effect of quercetin affects influenza viruses (H1N1, H3N2, H5N2), norovirus, herpes simplex virus, hepatitis C virus, Epstein-Barr virus, respiratory syncytial virus and the new strain of coronavirus SARS-CoV22;
the systemic intake of the combination of quercetin and vitamin C has a good prophylactic effect against SARS-CoV2 (Covid-19) in high-risk populations.

Method of administration:
1 tablet daily, during meals. If using for more than 12 weeks without interruption, consult a doctor.
