Quercetin

Learn more about the key ingredients found in Imuni Immune Defence  and how they combine to provide powerful immune support. 

Quercetin

Quercetin is a flavanol, or naturally occurring flavonoid polyphenol compound, found in several fruits and vegetables. It has antiviral and antibacterial properties.

Trials have shown that, in particular scenarios, Quercetin can reduce the incidence of viral upper respiratory tract infection. Namely, during periods of high mental stress or in the immediate post-exercise period following intensive exercise. These two scenarios are established as times when immune function is decreased and the incidence of viral infections is higher. 

Zinc 

Zinc has antiviral properties and also plays a role in immune function regulation. Adequate levels of zinc are also crucial for the development and function of particular cells in the body linked to immunity. 

Similarly to Vitamin D, there is widespread Zinc deficiency in our population. An Australian study conducted with adults in Tasmania found that as many as 30% of men are deficient in this important mineral. 

Research has shown that zinc can reduce the symptoms and severity of cold and flu. It has also been shown to play a role in reduced incidence of upper respiratory tract infections. 

Vitamin D

Vitamin D is essential for normal immune function. Why? It’s an immune modulator. That’s to say it can modify the immune system to help improve its function.

The number of Australians who suffer from a Vitamin D deficiency is significant at 31%. For women, the proportion jumps to 39% with a deficiency. This number increases in winter.

One large study of more than 10,000 people found that daily Vitamin D3 oral supplementation can prevent acute respiratory tract infection. These benefits were more visible in those with a Vitamin D deficiency, although there were positive impacts for those people with normal Vitamin D levels. 

Vitamin C

Long lauded for its antiviral properties and its ability to support the immune system, Vitamin C plays a role in enhancing various immune cell functions. 

Vitamin C supplementation has been shown to shorten and alleviate symptoms of the common cold. 

Interestingly, when taken concurrently with Quercetin, there is evidence to show that Vitamin C may have a synergistic effect, increasing the efficacy of the Quercetin to optimise its antioxidant and antiviral effects.
