Feed orally by adding the recommended amount with the included scoop.

The scoop is equivalent to ¼ teaspoon.

Three types of Biotics:

  • Prebiotics: Food to help promote the growth of beneficial bacteria in the gut.
  • Probiotics: Live microorganisms that support a healthy microbiome.
  • Postbiotics: Metabolic substances produced by probiotics. Unlike probiotics, postbiotics do not contain any live bacteria. Their stable compounds enhance gut barrier function.

AstraGin® is a patented, proprietary blend of Astragalus and Ginseng extracts, specially formulated to provide full-spectrum gut health benefits and support gut wall health.

AstraGin® promotes Integrity of the Gut Lining:

In a healthy intestinal environment, a thriving community of beneficial microorganisms, known as the microbiota, resides in the lumen. When the protective barrier of the gut lining is compromised it can disrupt the delicate balance of the microbiota. Astragin has been shown to promote integrity of the intestinal barrier, leading to increased gut health and overall well being.

    Life changing

    Although this review seems to be placed under the reviews for calming support, I am not sure which product is making the difference in my dogs. I have them on 4 Fera Pets products. Cardiac support, calming, probiotics and post biotics.

    My male dog is 11 and he has mitral valve disease. His heart has enlarged due to his cardiac disease. We saw a change for the worse and started him on Cardiac support just after we began a second heart medication. I am not sure if it is the combination of both, or one over the other, but there is a positive change in him so I will continue with both therapies.

    My female who is 8 has been experiencing stomach upset for a very long time. We have tried everything ! She would wake at 5 am or earlier many mornings. I would wake earlier because her belly would gurgle so loudly. As soon as I heard it, I knew she would be waking me to go outside to eat grass and would not eat her breakfast. I have her on calming support plus the pro and post biotics. She is like a new dog and she isn't even consuming the recommended daily allowance yet. It is quite evident that she is feeling better, she is not waking early, not looking to go outside to search for grass and is excited to eat her daily meals. She is playing more and it warms my heart to see her feeling so well.

    I will forever supplement my dogs with your products. Thank you!

    Amazing!

    This stuff has really been a God-send for my little, old terrier mix that has recurrent diarrhea issues. It’s helped more than anything he has ever tried! Thank you Fera Pets!

    No More Messy Poos

    Most people are familiar with probiotics, but are you aware of the many benefits of postbiotics? Once again, Fera Pets has formulated a pawsitively magnificent product that supports a healthy intestinal tract while enhancing immunity called Postbiotics Plus. My pup loves eating anything she can find in the backyard, and sometimes this upsets her tummy and a mess comes out the other end. Postbiotics Plus by Fera Pets helps her maintain normal digestive function by giving her gut extra microbiome support. By sprinkling Fera Pets Probiotics and Postbiotics over her food everyday, her tummy stays happy and healthy, and I don't have to worry about messy poos.
