Acute GI disturbances in dogs and cats — loose stools, diarrhea, sudden dietary changes, stress colitis — call for rapid intervention. The challenge is getting effective ingredients into an unwell pet quickly and reliably. Aventi GI Complete Paste solves this elegantly: a palatable oral paste that can be administered directly into the mouth by syringe, making it ideal for pets who are too unwell to eat normally, or for situations where you need fast, reliable dosing.
Aventi GI Complete Paste from Aventix is the paste format of their flagship GI restoration formula — a comprehensive synbiotic registered with Health Canada as a Veterinary Health Product. The same clinically studied multi-strain probiotic, prebiotic, yeast, nucleotide, electrolyte, and B vitamin complex found in the powder version is delivered here in a syringe-ready paste format.
Each ml of paste provides up to 7.6 billion CFU of beneficial bacteria including Lactobacillus acidophilus, L. plantarum, and multiple other validated strains, alongside Saccharomyces boulardii (beneficial yeast), FOS and MOS prebiotics, natural antimicrobial peptides (lactoferricin B and nisin A), electrolytes for fluid balance support, and key B vitamins. The paste consistency allows precise weight-based dosing: 1 ml per 5 kg body weight per day.
The paste format excels in acute clinical situations: post-surgery recovery, parvo recovery support, severe acute diarrhea, or any situation where reliable oral delivery matters more than meal-mixing convenience.
Key Active Ingredients per ml of Paste:
-
FOS 190 mg / MOS 38 mg: Prebiotic complex
-
Multi-strain probiotics up to 7.6 billion CFU: L. acidophilus, L. plantarum, L. rhamnosus + more
-
Saccharomyces boulardii: Anti-diarrheal beneficial yeast
-
Electrolytes: Sodium, potassium, magnesium, calcium phosphate
-
B Vitamins: Niacinamide, thiamine, riboflavin, pyridoxine
Directions for Use:
Give 1 ml per 5 kg body weight by mouth daily, divided into morning and evening doses if preferred. Administer for 1–2 weeks or as directed by your veterinarian. Can be given directly by syringe or mixed into a small amount of food.
Supplement Advisor's Note:
The paste format is particularly valuable for cats, who often refuse food supplements when they're feeling unwell. Syringe administration into the side of the mouth (the cheek pouch area) is usually well-tolerated. Keep the 1 ml per 5 kg dosing in mind — a 4 kg cat needs less than 1 ml per day, so one 15 ml tube represents a 15+ day supply for most cats. For travel-related GI upset in dogs, starting the paste the day before travel and continuing for 2–3 days after is a practical protocol.
Frequently Asked Questions
Q: Why choose paste over powder or tablets?
A: Paste is ideal for pets who won't eat normally during illness, for precise syringe dosing, or when you need to confirm the full dose was administered without relying on the pet eating their food.
Q: How quickly does it work?
A: Stool improvement can be seen as early as 12 hours in some cases. Consistent use for 3–5 days typically resolves most acute GI upsets.
Q: Is this safe to give alongside antibiotics?
A: Yes. Saccharomyces boulardii is unaffected by antibiotics and is particularly helpful during antibiotic therapy to prevent secondary diarrhea.
Q: Is this registered with Health Canada?
A: Yes, as a Veterinary Health Product (VHP).
