Zesty Paws Aller-Immune Flavor Infusions Ingredients

  • EpiCor® — This postbiotic is a whole food fermentate made using Saccharomyces cerevisiae yeast that goes through a closely held trade secret fermentation and drying process. This process produces metabolites, including proteins, polyphenols, vitamins, minerals, amino acids, polysaccharides, and fiber. Numerous studies have demonstrated that EpiCor® postbiotic helps support the immune system, decreases inflammation, and modulates the gut microbiota.
  • Apple cider vinegar — Apple cider vinegar has various healthful properties, including antimicrobial and antioxidant effects, and may boost skin health.
  • Colostrum — Mother cows produce bovine colostrum, which contains particular nutrients, including antibodies, growth factors, cytokines, and proteins, to help their newborn calves thrive. Your dog also can benefit from bovine colostrum because the nutrients help regulate the immune system and have natural antibacterial and anti-inflammatory properties. 
  • Salmon oil — Salmon oil is exceptionally rich in omega-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Research suggests that these omega-3 fatty acids reduce inflammation by decreasing pro-inflammatory chemicals produced by immune cells, and they may have beneficial effects on skin health.
  • Quercetin dihydrate — Quercetin is a pigment that belongs to a plant compound group called flavonoids, which have antioxidant properties that allow them to neutralize free radicals. Quercetin may decrease inflammation and allergy signs and help maintain normal histamine levels.
  • Astragalus root — This herb has been used in traditional Chinese medicine for centuries to boost the immune system and reduce inflammation.

Zesty Paws Aller-Immune Flavor Infusions Rave Reviews

Zesty Paws Aller-Immune Flavor Infusions receive 4.7 out of 5 stars on Chewy, and 96% of users would recommend the product to a friend. 

  • “My dog is allergic to everything. She is in and out of the veterinarian’s office, has had multiple prescription medications, steroid shots, special diets, and much more. She scratched herself raw. Then we tried Zesty Paws Aller-Immune Flavor Infusions on a cyber Monday deal. Hallelujah! One week on this stuff and there was drastic improvement and her fur has almost filled back in. Nothing has worked this well.”
  • “Zesty Paws did the trick. Last year my dog was covered in sores and constantly scratching. I took him to the veterinarian for an allergy shot. This year I started giving Zesty Paws to him at the onset of allergy season and avoided a veterinary visit.”

Always ask your veterinarian before starting your dog on a dietary supplement.
