Nutramax Proviable-Forte Chewable Tablets

Proviable-Forte Chewable Tablets use the same seven bacterial strains found across Nutramax's Proviable line — Enterococcus faecium NCIMB 30183, Bifidobacterium bifidum NCIMB 30179, Streptococcus thermophilus NCIMB 30189, Lactobacillus helveticus NCIMB 30184, Lactobacillus delbrueckii NCIMB 30186, Lactobacillus casei NCIMB 30188, and Lactobacillus plantarum NCIMB 30187 — but at a higher guaranteed minimum: "Total Bacteria min....10 billion CFUs per chewable tablet," double the 5 billion CFU floor printed on the standard Proviable tablet's own label. The fact-pack doesn't indicate whether that 10 billion is guaranteed through expiration or only at the time of manufacture. No prebiotic ingredient is listed for this version, and storage is the same shelf-stable setup as the rest of the line: room temperature, under 77°F, out of direct light.

There are no health claims printed on this label beyond the strain list and CFU count, and dosing is flat — one tablet daily regardless of the dog's weight, with no tiered chart. The fact-pack notes this item is "available exclusively from veterinarians," and no Amazon listing was found for it. That makes it a product you'd realistically need to source through a vet's office rather than buy online, and the label is written for dogs specifically rather than cats.

Transcribed from the guaranteed analysis. "Species only" means this label prints no numbered strain, so study results for a named strain don't transfer.
