Wellmune®, a leading natural yeast beta glucan derived from the cell walls of a proprietary strain of yeast called Saccharomyces Cerevisiae, clinically proven to help strengthen the immune system.
Quercetin is a plant flavanol from the flavonoid group of polyphenols, its beneficial effects come from its ability to function as an antioxidant inside your body and reduces free radical formation.
Ascorbic Acid functions as an antioxidant and is a nutrient your body needs to fight colds, flu’s, inflammation and most illnesses.

Why our advanced formula specifically contains these ingredients
Wellmune™
Ultra Nature Immune Defence contains Wellmune®, a leading natural yeast beta glucan derived from the cell walls of a proprietary strain of yeast called Saccharomyces cerevisiae, clinically proven to help strengthen the immune system. It is a 100% natural ingredient with demonstrated immunomodulatory effects (15). Wellmune® works to support and improve the body’s natural immunity, so the body is well-equipped to deal with infections. Wellmune® primes key immune cells to help protect against the harmful effects of physical and lifestyle stress.
When Wellmune® is ingested, immune cells in the gastrointestinal tract take it up and transport it throughout the organs in the body, releasing beta glucan in smaller pieces by immune cells over a series of days. These smaller pieces attach themselves to an immune cell called neutrophils. Because neutrophils make up such a huge part immune cells (40-60%), this allows Wellmune® to spread efficiently.
By spreading throughout the immune system, Wellmune® is able to strengthen major functions, without overwhelming the system.
Wellmune® works by releasing the natural beta glucan cells throughout the body to trigger immune defences.
Besides enhancing the immune system, Wellmune® exerts numerous other benefits such as:
· maintains overall physical health
· protects against the harmful effects induced by stress
· protects healthy energy levels and mental clarity
· has been clinically proven to help athletes stay healthy before and after high-intensity workouts or games
· to strengthen the immune system in the aged
increased reduction in upper respiratory tract infections displayed in subjects such as sore throats and runny nose
Ocibest™
Commonly known as Holy Basil or Tulsi, is rich in vitamin A & C, Calcium, Zinc, Iron and Chlorophyll. Working together with Quercetin, Ocibest™ functions as an adaptogen, helping the body adapt to stress and promote mental balance. Both these nutrients share the same strong antioxidant, antibacterial, antiviral, antifungal, anti-inflammatory and analgesic actions.
Vitamin D3
Activates natural killer cells important in defending the body against foreign pathogens. It plays a key role in supporting a healthy immune function.
Vitamin C, Selenium and Zinc
All combine to maintain the integrity and healthy function of your body’s immune system.

Is it ok to take Ultra Nature Immune Defence, even if cold and flu symptoms have set in?
The short answer is, Yes you can take Ultra Nature Immune defence, even after cold and flu symptoms have set in. Ultra Nature Immune Defence contains well-researched ingredients to prime and prepare the immune system. One such ingredient is Quercetin which is a pigment that belongs to a group of plant compounds called Flavonoids. Flavonoids are abundant in fruits, vegetables, grains tea and wine. The greatest beneficial effects of Flavonoids are that they act as antioxidants thereby reduces free radicals in the body. Free radicals are unstable molecules that may cause cellular damage when their levels become too high. Quercetin has been found to fight inflammation, boost immunity, combat allergies and maintain good health as well as have anti-viral and anti-bacterial activities (1). As a result of these findings, Ultra Nature Immune Defence may be used a prophylactic to modulate your immune system to prepare you for the cold and flu season as well as help with the inflammatory symptoms experienced with these conditions.

Numerous studies support the use of the entire plant. It’s therapeutic value is that it is high in nutrients such as Vitamin A and C, Calcium, Zinc, Iron and Chlorophyll (2).

Each recommended daily dose of Ultra Nature Immune Defence contains a therapeutic dose of 3000 mg of Ocimum Tenuiflorum.
Why does Ultra Nature Immune Defence contain a yeast in its formula?
The yeast found in Ultra Nature Immune Defence is called Saccharomyces cerevisiae. This is the most common yeast used in food fermentation. Saccharomyces cerevisiae contains beta-glucans found in the cell wall and belongs to a group of sugars known as polysaccharides. Ultra Nature Immune Defence uses Wellmune™ as the source of Beta Glucan in its formulation. Beta Glucan is an immune modulator that trains the body to defend against pathogens. It does this by adjusting the normal immune response to respond more effectively when a pathogen has been detected (4). Each recommended daily dose of Ultra Nature Immune Defence contains a therapeutic dose of 250 mg of Saccharomyces Cerevisiae.
