Multi-Strain Probiotic Support for a Balanced Gut Microbiome
The gut microbiome is one of the most complex and consequential systems in your pet's body — influencing not just digestion but immune function, mood, skin health, and resistance to infection. Antibiotic use, stress, dietary changes, illness, and aging all disrupt microbiome balance. A targeted, multi-strain probiotic supplement helps re-establish that balance by replenishing beneficial bacterial populations that have been depleted.
Rx Biotic by Rx Vitamins for Pets is a multi-strain probiotic powder formulated for dogs and cats. It provides diverse beneficial microorganism strains in meaningful colony-forming unit (CFU) counts — delivered in a palatable powder that mixes easily into food. Manufactured to NASC quality standards by a veterinarian-developed company with an established track record in integrative veterinary nutrition.
Key Features
-
Multi-Strain Formula: Diverse probiotic strains colonize different niches along the GI tract — providing broader coverage than single-strain products.
-
Meaningful CFU Count: Provides a viable colony-forming unit count sufficient to establish colonization rather than simply passing through.
-
Prebiotic Inclusion: Probiotic effectiveness is enhanced by co-administration with prebiotics that provide the substrate for bacterial growth.
-
Palatable Powder Format: Mixes easily into wet or dry food for daily administration without resistance.
Directions for Use
Sprinkle onto food once daily. Refrigerate after opening to preserve probiotic viability.
- Cats and small dogs: 1/4 teaspoon daily
- Medium dogs: 1/2 teaspoon daily
- Large dogs: 1 teaspoon daily
Supplement Advisor's Note
One of the most evidence-supported applications for probiotic supplementation is post-antibiotic recovery. Broad-spectrum antibiotics can reduce beneficial gut bacteria by 80–90% within 3–5 days — and without supplementation, full microbiome recovery can take months. Starting a multi-strain probiotic within 24 hours of beginning antibiotics (or immediately after completion) significantly shortens the dysbiosis window. Store in the refrigerator after opening: probiotic CFU counts decline measurably at room temperature over weeks.
Frequently Asked Questions
When is the best time to give this — with food or without?
With food. The buffering effect of food protects probiotic organisms from stomach acid, significantly improving their survival rate into the intestinal tract where they're needed.
How long should I use this?
For post-antibiotic recovery: at least 4–6 weeks. For ongoing maintenance: indefinite daily use is safe and commonly recommended for pets with a history of digestive instability.
Can I give this to a cat who is currently on antibiotics?
Yes — space the probiotic administration at least 2 hours from antibiotic doses to avoid the antibiotic destroying the probiotic organisms before they can establish.
Does refrigeration matter?
Yes. Probiotic viability declines faster at room temperature. Refrigerate after opening and use within the period indicated on packaging for best results.
