Nutramax Proviable-DC Capsules

Proviable-DC capsules from Nutramax carry the same seven-strain bacterial blend as the brand's standard Proviable tablets — Enterococcus faecium, Bifidobacterium bifidum, Streptococcus thermophilus, Lactobacillus helveticus, Lactobacillus delbrueckii, Lactobacillus casei, and Lactobacillus plantarum, each listed with its NCIMB strain code on this label. The guaranteed analysis states "Total Bacteria min....5 billion CFU's per capsule," meaning 5 billion CFU is the floor per capsule. As with the chewable tablets, the fact-pack doesn't say whether that 5 billion holds through the expiration date or is only measured at manufacture — that detail just isn't on the label. This version does include a prebiotic, fructooligosaccharide, which the tablets don't list. Storage is room temperature, under 77°F, away from direct sunlight.

The label carries no stated health claims, and there's no indication of when the CFU guarantee applies. Dosing is one capsule a day for any dog or cat, with no weight-based tiers — the same flat dose Nutramax uses regardless of pet size. That simplicity cuts both ways: easy to administer, but there's no label guidance for very small or very large animals beyond "one a day." Unlike the chewable tablets (dogs only), this capsule version is labeled for both dogs and cats. It has an Amazon listing under ASIN B001O3UE9E.

What's in it, strain by strain

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