This 400 Million CFU (colony forming units) probiotic blend gently restores essential beneficial microflora naturally occurring in the avian gastrointestinal tract, especially after disruption due to antibiotic use.

Natren probiotics are the true foundation for your bird’s nutritional needs. Our probiotic powders are packaged in amber glass bottles with steel lids and shipped to you in a refrigerated box. We do this because probiotic bacteria can be killed by light, heat, pressure and moisture. We also guarrante our product's potency to expiration when refrigerated storage requirements are met.
