Vitamin C + Quercetin Complex 90 Capsules

Vitamin C + Quercetin Complex is a targeted and synergistic combination of nutrients designed to support your immune health, respiratory health, and healthy inflammatory balance. With 400mg of high-quality vitamin C, alongside potent plant-based ingredients like quercetin, bromelain, rutin, and citrus bioflavonoids, this formula helps your body respond to seasonal changes, balance histamine levels, and maintain clear airways.

Our Vitamin C + Quercetin Complex capsules are ideal for anyone looking for a natural way to support their immune function and respiratory health, particularly those who suffer from allergies or hay fever.

Histamine is a compound produced in the body as part of an allergic reaction, and it is what causes swelling, rashes, itching, sneezing and mucous production when the immune system reacts to a trigger. Symptoms can occur in the nose, lungs, throat, sinuses, ears, lining of the stomach or on the skin. This unique formula helps keep the nasal and respiratory airways functioning normally.

Alongside vitamin C, this formulation features citrus bioflavonoids, quercetin, rutin, and bromelain.

Bioflavonoids are antioxidant compounds synthesised by plants, which may help support a healthy inflammatory response, cellular health, and cellular signalling/communication. This formula contains citrus bioflavonoids as a standardised extract of 50% hesperidin.

Quercetin is another bioflavonoid found commonly in berries, onions and apples, and is thought to play an important role in modulating the body's histamine response.

Rutin is a bioflavonoid found in apples, buckwheat, and green and black tea. Traditionally used to support circulation and blood vessels, rutin has powerful antioxidant properties, and also helps the body use vitamin C.

Bromelain is a protein digesting enzyme found only in the stems of fresh pineapple, traditionally used as a digestive aid. Research continues to highlight its potential benefits in reducing inflammation, and supporting healthy nasal and respiratory airways.

A standardised herbal extract is a specific concentration of one or more of the chemical compounds found in the plant. It guarantees that the potency and amount of active compounds contained in the product is the same as those advertised on the label and is consistent from batch to batch.

With standardised herbal extracts, you know you're getting a sufficient amount of the beneficial compound, as determined by scientific evidence.

As well as supporting the body's immune system response, vitamin C also supports healthy skin, bones and teeth. It contributes to normal energy-yielding metabolism and can reduce feelings of tiredness and fatigue. Vitamin C also has a role in supporting the normal function of the nervous system and psychological function as well as protecting cells from oxidative stress caused be free radicals and even increases iron absorption.
