What is Immune SURE?

Immune SURE 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.

Immune SURE is not a substitute for veterinarian-prescribed antibiotics.

The ingredients in Immune SURE 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's immune system does not become compromised at these life stages.

What is Immune SURE used for?

Immune SURE is a multi-purpose formula designed to support the immune systems of cats. It is Pet Wellbeing's primary formula when immune system support or maintenance is indicated.

A note from our veterinarian...

You and your veterinarian are the best judges of what type of immune support your cat will benefit from. Immune SURE 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.

Immune SURE 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 Immune SURE 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 cat 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.

Does it come with a guarantee?

Yes! Immune SURE comes with a Five-Star Experience or it's FREE.

Immune SURE is Formulated With:

  • Andrographis herb (Andrographis paniculata): A tropical and subtropical herb that has been used in Traditional Chinese Medicine for many hundreds of years, Andrographis is receiving increasing interest in the West. Studies have isolated an antiviral component and also some activity against the 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 have been the subject of numerous studies for immune system support. Echinacea has been shown to exert an antiviral effect by stimulating an immune response rather than directly affecting a virus itself. Echinacea has also been shown to increase white blood cell counts and initiate general immune response and resistance.
  • Usnea thallus (Usnea barbata): Also called "Old Man's Beard", constituents isolated from Usnea lichen have shown an antimicrobial action against bacteria, viruses, and fungi.
  • Goldenseal root (Hydrastis canadensis): Goldenseal is often indicated for a healthy immune system response when infection is present. It has been shown to have a direct antimicrobial effect on many bacteria and viruses.
  • Elder berry (Sambucus nigra): Elder berries, high in flavonoids, have a long history of use for colds, influenza, fever, enlarged glands and tonsils, and sinus infection. Elderflower and berry have shown clinical effectiveness with its antioxidant and antiviral activity.
  • Licorice root (Glycyrrhiza glabra): Numerous bioactive constituents have been found in Licorice with glycyrrhizic acid considered to be the most active. Pharmacological studies indicate antiviral, antimicrobial, anti-inflammatory and anti-oxidative activity. Licorice is also used as a natural sweetener due to its sweet taste.
  • Propolis resin: This is an exudate collected from bee hives. Bees keep their hives protected from fungus and other life threatening microbes by sealing cracks in their hive structure with this substance. It is mainly collected from poplar trees and is considered a natural antimicrobial. When propolis is harvested, bees continue to make more for their hive.
  • Ginger rhizome (Zingiber officinale): A small amount of ginger is added to this formula as a "harmonizer" and for its known antibacterial properties.
