Nutramax Proviable-Forte Sprinkle Capsules

Proviable-Forte's label lists seven organisms -- Enterococcus faecium, Bifidobacterium bifidum, Streptococcus thermophilus, Lactobacillus helveticus, L. delbrueckii, L. casei and L. plantarum -- all printed as bare species names, with no strain code on this capsule's own panel. (Nutramax's own site documents NCIMB strain numbers for this fixed seven-organism blend elsewhere; the capsule label we reviewed doesn't print them.) The capsule carries one combined guarantee of 10 billion CFU; the label doesn't say how that splits across the seven organisms, or whether it holds through the printed expiry date or only at manufacture. One prebiotic, fructooligosaccharide, is listed with no stated amount. Storage is shelf-stable below 77 degrees F.

There's no weight-based dosing table on this label: one capsule a day, swallowed or sprinkled on food, regardless of the dog's size. Nutramax markets this as the vet-channel sibling of Proviable-DC, which carries the same seven organisms at half the CFU (5 billion); we found no Amazon listing for the Forte capsules during this research pass, consistent with Nutramax selling it through veterinary clinics rather than retail. The label claims "Clinically Researched" and "Vet Recommended Probiotic" without citing a specific study on this product by name.

Questions people ask about Nutramax Proviable-Forte Sprinkle Capsules

What's different between Proviable-Forte and Proviable-DC?

Both list the same seven organisms; Forte's capsule guarantees 10 billion CFU against DC's 5 billion. Neither label states what else, if anything, changes between the two.

Does it need to be refrigerated?

No. Store below 77 degrees F, out of direct sunlight, per the label.

Can I buy it on Amazon?

We didn't find an Amazon listing for the Forte capsules during this research pass -- Nutramax appears to sell this one mainly through veterinary clinics rather than retail.

Is the prebiotic amount stated?

No. The label lists fructooligosaccharide as an ingredient but doesn't print a quantity for it.

Are any of the seven organisms strain-numbered on this label?

Not on the capsule panel we reviewed -- all seven are printed as bare species names. Nutramax's own site does document NCIMB strain numbers for this blend elsewhere, just not on the package.
