Overview
["Royal Canin's powder supplement is built around a single, precisely measured strain, Saccharomyces boulardii, at 1.13x10^9 CFU per 1 gram packet, sold in a 30 count box for dogs of all breed sizes. Unlike most of the chews in this category, this is a powder meant to be mixed into food rather than fed directly.", 'The label focuses on digestive and immune health, with Stomach listed as the specific use. Royal Canin is a well known name in veterinary nutrition, which may appeal to owners who prefer a brand with an established clinical reputation over newer supplement companies.', "At $30.99 for 30 packets, it's the priciest product in this batch, but it also carries strong numbers: a 4.6 star average across 453 reviews and about 1,000 units bought in the past month, among the highest purchase volume here."]

Performance notes
The active ingredient spec lists a precise dose, Saccharomyces boulardii CNCM I-1079 at 1.13x10^9 CFU per 1 gram packet, which is more clinically specific than most competitors in this batch that either list blended strains without exact counts or omit CFU figures entirely. It's a powder rather than a chew, so it needs to be mixed into your dog's food.
