What is Immune SURE?

ImmuneSURE with Vitamin C and zinc is a potent supplement for supporting feline immune function. We call this product our "comprehensive immune formula" because it is capable of supporting the body's natural defences.

ImmuneSURE is not a substitute for veterinarian-prescribed antibiotics.

The ingredients in ImmuneSURE will not compromise the natural feline gut flora, a key component of healthy immunity. It has been said that 80% of a mammal's immunity is in the gut.

As with humans, the young and the elderly are the most vulnerable, so it is important to pay particular attention that our feline' immune systems do not become compromised at these life stages.

What is ImmuneSURE used for?

ImmuneSURE is a multi-purpose formula designed to support the immune systems of cats.

ImmuneSURE is also used as a secondary formula, added to a regime to support body systems such as the urinary system or the respiratory system.

For other conditions that require immune system maintenance and support, Immune SURE is Pet Wellbeing's primary formula, whenever the immune system requires extra support.

A Note from our Veterinarian...

You and your veterinarian are the best judges of what type of immune support your cat will benefit from. ImmuneSURE is absolutely not a substitute or alternative to antibiotics. What we do know is that antibiotics have seen extensive use (some would say overuse or indiscriminate use) over many decades but there is certainly a very appropriate time and place to use them. Herbal medicine provides some potent and very effective antimicrobial products that have been proven to exhibit a broad spectrum of activity.

ImmuneSURE can be used as the primary formula; it can also be used as a secondary formula. For example, for respiratory, eye or urinary system support, I would first use a product specific to those body parts and recommend ImmuneSURE as an adjunct to help maintain overall immunity. 

Probiotics are also a key treatment for supporting immune function and can be given daily. 

Never underestimate the health potential of optimal nutrition. Feeding your cats a natural, healthy diet is the best immune support you can give them. If you haven't already, consider an unprocessed, grain-free diet for your cat.

*Never give an animal antibiotics prescribed for a human.

Can my cat take ImmuneSURE with medications?

Do not use with blood thinners. Use with caution in cardiac or kidney conditions, or if taking steroid medications. Use with caution if animal has a known allergy to bee stings as this product contains propolis, derived from bees.

Are there any side effects or precautions?

Not to be used during pregnancy or nursing. If animal's condition worsens or does not improve, stop product administration and consult your veterinarian. Excessive or long-term use may contribute to water retention or hypertension. An examination from a veterinarian is recommended prior to using this product.

Does it come with a guarantee?

Yes! ImmuneSURE comes with a 90 day money-back guarantee.

  • Andrographis herb (Andrographis paniculata): A tropical and sub-tropical herb that has been used in Traditional Chinese Medicine for many hundreds of years, Andrographis is receiving increasing interest in western countries. Studies have isolated an anti-viral component and also some activity against herpes virus. In traditional use, it has been employed for the liver, stomach and to induce normal appetite.
  • Echinacea root (Echinacea angustifolia): Echinacosides and polysaccharides in Echinacea are the subjects of numerous studies for immune system support. Echinacea has been shown to exert an effect on immune response, rather than directly affecting a microbe itself. Echinacea has been shown to maintain white blood cell counts and initiate general immune response.
  • Usnea thallus (Usnea barbata): Also called "Old Man's Beard", Usnea's anti-microbial constituents have been isolated in studies, showing an action on bacteria, viruses and fungi.
  • Goldenseal root (Hydrastis canadensis): Goldenseal is strongly indicated to help maintain a healthy immune system. It has been shown to have a direct affect on different types of microbes and by many herbalists, is considered and essential anti-microbial in their dispensary for the immune system. We use only cultivated Goldenseal so as not to threaten this endangered species in the wild.
  • Elderflower (Sambucus nigra): Elderflowers, high in flavonoids, have a long history of use for sinus, throat, and glandular support. Elderflower and berry have shown clinical results in having antioxidant activity.
  • Licorice root (Glycyrrhiza glabra): Numerous bioactive components have been found in Licorice with glycyrrhizic acid being considered the most active constituent. Phamacological studies indicate broad activity in contact with microbes. Licorice is also used as a natural sweetener due to its sweet taste.
  • Propolis: The substance is produced by bees to seal gaps in the hive and protect against microbes that could harm hive immunity. It is commonly used for naturally supporting immunity in humans and animals.
  • Ginger (Zingiber officinale) rhizome: Ginger adds warmth to this formula and helps the other ingredients to circulate through the body.
