Digestive health problems — from acute diarrhea to chronic GI sensitivity — are among the most common reasons pet owners seek support for their cats and dogs. The intestinal microbiome is increasingly recognized not just as a digestive organ but as a critical component of the immune system, with the gut housing over 70% of the body's immune cells. Supporting it with the right combination of evidence-based ingredients produces benefits well beyond stool quality.
Aventi GI Complete Chewable Tablets from Aventix deliver the brand's comprehensive GI formula in a convenient chewable format. Registered with Health Canada as a Veterinary Health Product, each tablet provides 9.6 billion CFU of a multi-strain probiotic complex alongside prebiotics, yeasts, nucleotides, B vitamins, and electrolytes — making it one of the most complete synbiotic formulas available in the Canadian veterinary market.
Each chewable tablet contains Lactobacillus acidophilus (7.2 billion CFU), L. plantarum (2.4 billion CFU), and multiple additional Lactobacillus strains, plus Enterococcus faecium and Pediococcus pentosaceus. Saccharomyces boulardii provides yeast-based anti-diarrheal support. FOS (480 mg) and MOS (48.6 mg) prebiotics nourish beneficial bacteria while creating an unfavourable environment for pathogens. Natural antimicrobial peptides lactoferricin B and nisin A add another layer of protection against GI pathogens. B vitamins and key electrolytes support the metabolic and hydration needs of the GI mucosa.
The tablet format is practical for owners who want an easy-to-dose, long-term GI support supplement rather than the short-course paste or powder formats. Tablets can be given directly, crumbled over food, or dispensed in a pill pocket.

Directions for Use:
Cats and dogs 0–7 kg: 1 tablet daily. Dogs 7–14 kg: 2 tablets. Dogs 14–20 kg: 3 tablets. Dogs 20–34 kg: 4 tablets. Dogs over 34 kg: 5–6 tablets. Give for 1–2 weeks for acute GI issues, or as directed by your veterinarian for ongoing support. Dose can be divided morning and evening.
Supplement Advisor's Note:
The tablet format is the most convenient option for ongoing daily GI maintenance — ideal for dogs and cats with chronic GI sensitivity, IBD-adjacent conditions, or those who regularly experience diet-related loose stools. The 120-tablet count offers a full course for most dogs at maintenance dosing. One notable advantage of the multi-strain approach here is that different bacterial strains colonize different segments of the GI tract — a single-strain probiotic leaves significant portions of the gut ecosystem unsupported.
Frequently Asked Questions
Q: How is this different from Aventi GI Essentials sachets?
A: GI Complete has a significantly higher probiotic count (9.6 billion CFU per tablet vs. a lower maintenance dose in GI Essentials) and adds the nucleotide and electrolyte components. GI Complete is better suited for acute GI upset or more serious ongoing issues; GI Essentials is designed for daily maintenance in otherwise healthy pets.
Q: How long should I continue treatment?
A: For acute GI upset, 1–2 weeks. For chronic GI support, ongoing daily use may be appropriate — discuss with your veterinarian.
Q: Is this safe for kittens and puppies?
A: Generally yes for kittens and puppies over 8 weeks, but consult your veterinarian for young animals.
Q: Is this registered with Health Canada?
A: Yes, as a Veterinary Health Product (VHP).
