Organic Fermented Gut Extract

GUTOMIZER is a fermented herbal extract as a feed supplement for dogs of all ages, which is given daily with the feed. The aim of feeding is a stable intestinal flora, which helps to improve the animal’s well-being and maintain its health.

The GUTOMIZER contains naturally occurring enzymes, vitamins, antioxidants, and trace elements, all of which are essential for optimal health. It also contains lactic acid. Although there is a misconception of the effects of lactic acid on the body, it is a good energy source and helps the digestion of animal tissue. It is involved in preventing degradation processes that arise from microbial changes in the environment in the intestine that can cause digestive problems.

A good intestinal environment leads to better feed conversion through balanced digestive processes. It is crucial for a strong intestinal mucosa, which protects the organism from pathogens and toxins and also prevents excessive infestation with intestinal parasites.

So, I think it was the dewormer that sent my 4 month old puppy into diarrhea. I tried everything (pure pumpkin, slippery elm) and could not get rid of it. Then, I purchased the Rocketo Gutomizer (the fermented gut extract). Success! I am now able to rotate his complete raw food (even between different companies) and it does not faze him. Rocketo-firm poos! LOL

Our mini poodle had digestive problems and unsettled stomach sometimes. It is difficult to know if t is this or the new food from Rocketo that has settled his stomach so well, but I expect combination of the two. He’s now a really happy pup. No more tummy troubles.

Mr T has had a massive improvement in his tummy after being on this for about a month. Just a tiny bit needed per day, it helps his bowels move more smoothly and they are so much more healthy. Extra poos came at first (still healthy ones) so I assume it is helping him clear out any excess down there too. He barely gets bad breath or smelly dog smell any more either - used in combination with the chicken/beef raw food AND the wild boar/venison which he also loves!

I was looking for a probiotic style supplement for my dogs, particularly as one has had some trouble gaining weight recently so I wanted to boost all their health. Dogs seem happy on this. Only gripe was it was very difficult to pour when the bottle was full - it kept dribbling down the bottle and making a mess of my counter!

Love this as part of a natural approach to managing my dog's IBD. He'll also it up when I poor it over his food (doesn't drink it if mixed with water tho as suggested). It's worth a try.

I have been adding this product to my dogs Rocketo food. Carlos was diagnosed with chronic colitis and it is practically all I have thought about for the past nine months or so. During this time we have tried many different diets (prescribed kibble, home cooked, bone broth, organic frozen) together with prescribed medication. Absolutley nothing has helped until now until I discovered Rocketo . We switched two weeks ago for both dogs and, dare I say it, there has been two days without blood in Carlos' healthy formed stools. Way Hay!!! I am praying we have cracked it. I will tell my vet all about it once we have had another few clear days - a much better alternative to medication as a treatment for colitis. My other dog Queenie has Addisons Disease so she too will benefit from an imporved diet. We are happy...

I use the Gutomizer for a couple of weeks now for my 2 old dogs with very sensitive stomach and colon and this works really great . Gives really good digesting and stool! Be careful not to use too much in the beginning, that can give too loose stool. Very healty product!

My dachshund mix rescue has a super sensitive stomach and liquidy poo. We usually get some tablets from the vet for that but it's always just a temporary fix. Gutomizer has improved his tummy problems immensely. Recommended it to everyone I know. Honestly, did not expect it to do much but I am so happy I decided to try it on a whim.
