Dylan is a 23 year old trakehner who this summer developed very itchy skin and reaction to fly bites. He’s always been a bit of a grumpy old man which I thought could be related to his gut health. Since using Microbz his skin is brilliant and he’s so much happier in his demeanour. He has it every day and his skin is healthy and he’s happy, best product ever!

Tedward is fussy and stressy. He loves his microbz !!!! He literally licks his bowl clean with it in which is amazing as he's normally really dubious about anything in his feed. He's put more condition on and actually feels a bit stronger. He is less stressy too. We are really pleased!

I can tell when my ponies don’t have it and are on grass, Microbz helps them manage sudden changes of pasture and keeps them happy in work. Much less spooky and more active

I’ve been read up a lot about this for my horses. I’ve one with EMS and another with fecal water syndrome. I really do believe that a healthy gut is absolutely key for all of us including animals. So I bought my first 5 litre of Microbz for horses and a dispensing pump to give it a try. Trying to work out which does was correct for them, so I started with the lowest does and they both lived it. Then I had my summer livery at the end of March and I put him on it too. I will say I didn’t notice a difference for a couple of weeks, but then I noticed no fecal water and a much slimmer belly on Alfie. The EMS one seemed much happier with very little food and again looked better in his whole body. Then the livery started to look the best I’ve ever seen him look in the 3 years he has been coming to me for the summer. Their coats are incredible and very strangely all have been noticeable more relaxed . Going to try the dog one next but highly recommend the horses one, but don’t expect to see instant results as it takes time to rebalance the gut.

Dexter is a 12 year old Gypsy cob. He has ems and mallanders. He was having fecal matter so thought I'd give it a go. No more fecal matter and his mallenders have not split open for a while now. I feel he feels better from being on microbz.

Major improvement in my boy, he has always had tummy issues and thus a little grumpy! He is now so laid back and a lot happier. His two old aunties are doing well on it too

Horses coats and skin look amazing! Bought more for our TB who is a bit stressed, she does seem less so in her environment.

I’ve been using this on and off since last year. I tend to offer it straight in a bucket alongside various herbs and I often use it during season changes. My mare can be quite itchy but since using this, I’ve definitely noticed a difference in her. Their coats are starting to come out now as spring is impending so we’ve reintroduced it to help them get through the change and they love it. It’s a great training tool too-they find it so tasty that been using it in a syringe to help my gelding build up a positive association with syringes since he hates being wormed.

I have been using Microbz for a little while. My horses seem to do well on it, but esrly days. As an equine holistic therapist, I have been happy to promote this product to my customers, especially on my Natural Gut Health workshops where we discuss how we can help improve our horses microbiome. I work with herbs for horses in my business, and feel that Microbz has an important place in the horses diet, alongside natural feeding.

Both horses are now on their 3rd bottle and we can see the positive impact on their mood and performance. Much calmer and comfortable

I started Cora on Microbz following the results of a deficiencies and dysbiosis hair test showing she was suffering with dysbiosis and had a leaky gut. The hair test was a final attempt to resolve her itchiness that she’d been suffering with for around 8 months at this point. I’d tried antihistamines, steroids and had an independent equine nutritionist out. She also suffers with equine water fecal syndrome which had got worse year after year. The treatments for this fixed it short term but it always came back. I was worried she wouldn’t eat her feed with microbz in as she can be very picky but it’s not been an issue. I can’t say 100% if the microbz has been the one cure as I’ve had to hit her with other supplements to fix the leaky gut. But she has no objection to eating her feed with it, she is producing properly formed fecal matter, we have the odd runny one but usually during times of excitement or stress (local shoot). Her itching has subsided it’s not 100% cured but she’s 100 times better than she was, she’d become dangerous with her urges to scratch and it didn’t matter to her who was in her way! I think Microbz has played a big part in all of this and for how much it costs I won’t be taking her off it any time soon. The customer service is great, orders are received within a day or two and are always well packaged.

MicroBZ is a good probiotic to use long term while the gut populates with beneficial microbes. It takes time for this to happen but improvements can be seen soon.

FAQs
How will feeding my horse a probiotic help with their coat and hooves?
There are three kinds of bacterial microbes good, neutral and bad. Horses need a balance of these and thankfully only a few of the good bacteria are needed to keep the bad and neutral in check. As long as the balance of good, neutral and bad bacteria remains constant and the gastrointestinal tract is stable then the horse stays healthy.
Why does my horse need this if they have access to pasture?
Modern soils and pastures lack the same natural microbial diversity that they once did. Factors such as weather changes, overgrazing and reduced plant variety mean that your horse might not be getting the full spectrum of beneficial microbes from forage alone.
Can I use microbz alongside my other supplements and medications?
Microbz is completely safe to use alongside other supplements. If your horse is on medication, we recommend consulting your vet before introducing any new product, including probiotics.
I see it contains molasses, is this safe for my horse?
Yes, the molasses in microbz is used up during the fermentation process as food for the microbes. The result is a product with the taste and palatability of molasses, but without the high sugar content.
Can it be used in drinking water?
Yes, microbz can be added to drinking water. However, we recommend always providing a second source of plain water so your horse has a choice.
Can I add microbz to hot mash or boiling water?
No, avoid adding microbz to hot feed or boiling water, as high temperatures can kill off some of the beneficial microbes. Add it once the feed has cooled and is comfortable to touch.
