What is Immune SURE?

Immune SURE with Vitamin C and zinc is a powerhouse for supporting feline immune function. We call this product our "first-aid formula" because it is equally capable of supporting against viral AND bacterial microorganisms. The herbs in this formula have strong anti-microbial properties.

Unlike antibiotics, the ingredients in Immune SURE will not compromise the natural gut flora, a key component of healthy immunity. It has been said that 80% of a mammal's immunity is in the gut. By keeping this "first line of defense" intact, it not only helps combat current pathogens but may help prevent recurring infections that are more likely when the gut flora is weakened.

As with humans, the young and the elderly are the most vulnerable to infection, so it is important to pay particular attention that our felines' health 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 system against many of the microorganisms that can cause infections. Most notably these would be bacteria and viruses.

Immune SURE may help support against:

  • Viruses (such as FeLV, FIV, FIP and herpes)
  • Bacteria (such as gastrointestinal, urinary, skin and respiratory)
  • Parasites
  • Fungal problems
  • Allergic responses
  • Cancers
  • Environments where infections can be passed (such as kennels)

Many of the conditions above can receive treatment that is specific to that condition. For example, if your feline had a urinary tract infection, we would recommend Urinary Gold http://www.petwellbeing.com/products/urinary-gold-for-feline-urinary-tract-health as the primary formula to administer. Similarly, Life Gold http://www.petwellbeing.com/products/cat-cancer is designed to support pets with cancer.
In those cases, Immune SURE provides extra support and insurance for the immune system.

For other conditions such as viral infections, Immune SURE is Pet Wellbeing's primary formula.

Immune SURE can be used 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 feline will benefit from. 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 against bacterial and viral organisms.

Fortunately, we have ALL of these products at our disposal:  antibiotics and herbal-based broad antimicrobials such as Immune SURE.

Immune SURE can be used as the primary treatment when the animal presents with an infection; it can also be used as a secondary remedy. For example, for a respiratory infection, I would first use a product specific to that condition and recommend Immune SURE as an adjunct remedy to help maintain overall immunity. 

For a condition like feline leukemia virus (FeLV), feline immunodeficiency virus (FIV) or feline infectious peritonitis (FIP), Immune SURE would be principle natural treatment. While no cures for these conditions exist, the immune system requires support, possibly decreasing the likelihood of secondary infections.

Probiotics, such as Pet Wellbeing's Ultimate Probiotic 9 Strains, are also a key treatment for supporting immune function and can be given daily.


Never underestimate the health potential of optimal feline nutrition. Feeding your cat a natural, healthy diet is the best immune support you can give him or her. If you haven't already, consider an unprocessed, cereal-free diet.

*Never give an animal antibiotics prescribed for a human.

Can my cat take Immune SURE 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! Immune SURE comes with a 90 day money-back guarantee.
