Dourena’s Review
Written by Dourena from the sources under See the Research. No brand paid for this review or approved it. How Dourena makes money
What Stands Out
- Pre-portioned packets: one a day, no measuring.
- The label lists each probiotic organism with its own CFU amount.
- A short ingredient list: seven ingredients.
Things to Know
- The label gives one serving for every dog: 1 packet daily, with no weight-based amount.
- Zesty Paws’ product page says the formula includes “Yeast Extract”; the ingredient list names Saccharomyces boulardii, and the label lists “Yeast Extract (Saccharomyces boulardii)” with a live-organism count.
- No minimum age is stated by the brand.
- The label says it is intended for intermittent or supplemental feeding only.
- Gut and immune benefits, including those described for the DE111 strain, are Zesty Paws’ claims. See What the Manufacturer Says in the research.
- Sold as a box of 30 sachets.
