What’s unique about this combination?
Quercetin is a naturally occurring antioxidant found in several plants. In vitro (i.e. laboratory-based) and animal studies have demonstrated Quercetin’s antiviral and antibacterial properties. Human clinical trials have shown that Quercetin can reduce the incidence of viral upper respiratory tract infection in the immediate post-exercise period following intensive exercise and in individuals suffering from high mental stress, conditions in which it is known that immune function is decreased and the incidence of viral infections is higher(1-4).
Zinc is a key ingredient that has been selected for its antiviral properties and its role in the regulation of immune function. A substantial amount of scientific literature has documented the beneficial role of zinc in fighting respiratory tract infections such as common cold and flu. The World Health Organisation (WHO) estimates that up to one third of the world’s population is deficient in zinc. An Australian study of 497 Tasmanian adults showed that zinc deficiency was present in 18% of men over the age of 50 and 30% of men over the age of 70(5). We have intentionally included high doses of elemental zinc in IMUNI Immune Defence to boost zinc levels, to enhance the antiviral effects of Quercetin and to improve viral defence.
Vitamin C has long been known for its antiviral and immune boosting properties. While a balanced diet can certainly assist in maintaining healthy intake, viral infections are associated with an increased metabolism of Vitamin C and reduced circulating levels. Regular supplementation of Vitamin C during and immediately prior to viral infection can therefore assist in maintaining effective immune function. Vitamin C has also been shown to improve the bioavailability of Quercetin by helping recycle Quercetin into its active form thereby optimising its antioxidant and antiviral effects.
Vitamin D plays an important role in the immune response as an immune modulator. A large study of over 10,000 patients enrolled in randomised clinical trials demonstrated that daily oral supplementation with vitamin D3 can prevent acute respiratory tract infection. While effects were more pronounced in patients deficient in vitamin D, even those people with normal blood levels still gained some benefit from vitamin D3 supplementation(6). In Australia, Vitamin D deficiency is common and affects nearly one-third of adults aged over 25 years of age(7).

Glass is a material that will protect your product from moisture and can be recycled forever with no loss in quality or purity(22).
Did you know?
- Vitamin C increases bioavailability of Quercetin(2)
- In order to consume the same amount of Quercetin found in a single daily dose of IMUNI Immunity, you would have to consume more than 6.5 kg of red lettuce or 1.2kg of red onion every day!(11)
How much Quercetin should I take? Should I take it with food?
Taking into account safety considerations and scientific literature reporting a therapeutic daily dose of 500mg, this is the recommended daily dose of Quercetin in IMUNI Immune Defence which we recommend to be taken in separate doses of 250mg twice a day – that is, one capsule of IMUNI Immune Defence with breakfast and one capsule with dinner. Bioavailability of Quercetin may be enhanced when taken with vitamin C and absorption may be improved by taking Quercetin with food given that Quercetin is soluble in fat(2,8).
Why do I need to take IMUNI Immune Defence twice a day?
The half-life of Quercetin in the body has been reported as highly variable, ranging anywhere from 11 to 28 hours(3). This means that after a single dose, it could take as little as 11 hours to eliminate half this dose from the body. To ensure that you have sufficient amounts of Quercetin in your body around the clock, we recommend you take one capsule of IMUNI Immune Defence with breakfast and one capsule with dinner.
Under what circumstances should I take IMUNI Immune Defence?
Scientific evidence has shown the various components of IMUNI Immune Defence may be beneficial for prevention and treatment of respiratory tract infection, by reducing the incidence of infection as well as severity and duration of illness(2-5). We therefore recommend taking IMUNI Immune Defence to either prevent infection in times of higher incidence or to treat infection by taking it immediately at the onset of symptoms. Some times that you might consider using IMUNI Immune Defence for prevention of respiratory tract infection are listed here:
- For up to three months over the peak cold and flu season
- When exposed to a close friend or family member who is showing symptoms
- During periods of high stress, for example, following periods of intensive exercise or when under mental stress
- If affected by a chronic medical condition that might suppress your immune system*
*we recommend you talk to a doctor if affected by a medical condition; if using regular medications; or if you are pregnant or lactating. You should also talk to your doctor if symptoms are severe or persist despite treatment.
Is IMUNI Immune Defence safe?
Safety is our number one concern. IMUNI Immune Defence contains zinc which may be dangerous if taken in large amounts or for a long period. High doses of zinc can interfere with absorption of other ions such as copper, and can cause minor symptoms such as nausea(9,10). If you intend to use this product for periods longer than 12 weeks, we recommend you discuss this with your doctor. Quercetin can interfere with the metabolism of certain medications.
