VetriScience Extra Strength Gut Health for Dogs & Cats

VetriScience's Extra Strength Gut Health capsules list seven strains — Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus casei, Lactobacillus brevis, Bifidobacterium bifidum, Bifidobacterium longum, and Streptococcus thermophilus — at "7.5 billion CFU/capsule (guaranteed minimum)." The fact-pack doesn't specify whether that guarantee holds through the product's expiration date or is only measured at manufacture. The formula includes 75 mg of fructooligosaccharides (FOS) as a prebiotic. Storage is a cool, dry place at 70°F or below, with the added instruction to refrigerate after opening — so this one isn't fully shelf-stable once the bottle is opened. The label carries the NASC quality seal. It's also worth knowing this product was "formerly named 'Vetri Mega Probiotic,'" per the fact-pack.

The label does make some stated claims: it says the product "supports digestive health," "addresses occasional diarrhea/gas," and "supports immune function and healthy skin" — all label claims, not independent findings. No Amazon listing was found for this item. Dosing is weight-based for dogs (1 capsule daily under 40 lbs, 2 capsules at 40 lbs and up) with a separate half-capsule dose for cats, which fits an owner managing either species rather than dogs exclusively.
