Premium formula for immune defence

True D+efence is a premium blend of key vitamins and minerals proven to stimulate a healthy immune response. Each tablet contains Zinc (23mg) and Vitamin D3 (25 micrograms) to maintain immune function, Vitamin C (500mg) to defend the immune system and Quercetin (250mg) for antioxidant support.


Vitamin D3

True D+efence contains 1000IU of Vitamin D, an essential vitamin necessary for normal immune system function and a range of other bodily functions.


Vitamin C

Vitamin C contributes to immune defence by supporting the cellular function of the innate (non-specific) and adaptive (acquired) immune system.



Quercetin is a plant flavonoid (polyphenol) and provides antioxidant support, important for reducing free radicals formed in the body.



Zinc is involved in numerous aspects of cellular metabolism and plays a vital role in healthy immune function. Inadequate dietary zinc intake is not uncommon due to food intolerance and lifestyle choices. D+efence contains 23mg per dose to help you top up your daily zinc intake.

    • FAQ

      What is in D+efence?

      D+efence is comprised of evidenced based doses of Vitamin C, Vitamin D3, Quercetin and Zinc. Each ingredient is well-known/researched for their positive/strengthening effects on the immune system.

      When should I take D+efence?

      Any time of day is fine to take D+efence.

      What is quercetin?

      Quercetin is a plant flavanol from the flavonoid group of polyphenols. It has potent antioxidant properties which help to protect the immune system. Humans don’t make quercetin within the body so must consume it from fruit and vegetables – with the majority of us not eating nearly enough. Studies suggest that supplementing quercetin may promote antioxidant activity which can support the body against environmental agents thereby supporting the integrity of the body.
