Natren Inc.

I’ve been using Natren probiotics for over 15 years, and they continue to be my top recommendation for both canine and feline gut health. After testing several veterinary-grade probiotics, I found that Gastrovegidophilus was the only one that actually contained the live organisms listed on the label. This is essential, as many probiotic products lose potency or contain inactive strains by the time they reach the consumer. Natren’s unique encapsulation method helps protect the bacteria, ensuring they stay viable and effective. For pets with urgent digestive issues, I recommend starting with Caninedophilus or Felinedophilus for fast and reliable relief.
