EquiBrew is a high performance probiotic feed supplement for horses, ponies and foals at all stages of development.

EquiBrew is safe, non-toxic and Clean Sport compliant.

EquiBrew features extremely high microbial viability (minimum 109 CFU/dose lactobacilli) and activity along with a suite of beneficial metabolites.

EquiBrew is safe for use in sugar-sensitive horses. Sugars have been converted by our microbes into more microbes and beneficial organic acids. Virtually no residual sugar is left when bottled.

EquiBrew is an intact fermentation product with very high numbers of beneficial microbes and the equally beneficial metabolites they produce. This combination can only be found in BioBrew Ltd products.

Why is fresh best?

You would not enjoy being freeze-dried and neither do microbes.

The process of freeze-drying damages the vast majority of the microbes being processed. Only 1/10th or even 1/100th for the microbes you start with will survive the process in a condition from which they may possibly be brought back to life.

The process of reanimating a freeze-dried culture takes another heavy toll with again ONLY 1/10th to 1/100th of the microbes that may have been able to survive actually finishing the process in a condition where they can metabolize and reproduce.

The above means that only a tiny fraction, 1/100th to 1/10,000th of the microbes that enter the freeze-drying process will ever wake up and get to work trying to be a probiotic. Further, this process takes time meaning that the tiny fraction of the microbes that make it through the grueling process can only benefit that lower part of the gut that they find themselves in once they get to work.

The live, active microbes in BioBrew products get to work from the moment you administer them. There is NONE of the lag time or massive losses associated with freeze-dried products.

The microbes in BioBrew products are selected to survive the rigors of the digestive system, including stomach acids and bile salts. They do their job the entire trip through the digestive tract.




“I started in July and noticed results within 2 or 3 weeks”

"…. after a busy season we thought we will stop feeding (including our EquiBrew). Within 3 days they were feral! So we put them back on EquiBrew and overnight we got our lovely calm horses back! It pays to keep the maintenance dose of EquiBrew up, even in the rest periods!" Fee O'Neill, Canterbury



Georgia Wiltshire, Rotorua, EquiBrew sponsored rider.

I would like to thank EquiBrew for there ongoing support and sponsorship. EquiBrew is a fantastic probiotic it has the horses looking and feeling great. I have found Equibrew very beneficial for my mares.


"Roger That was a 40:1 underdog with a history of picky eating and poor recovery after hard work. His Trainer Antony Fuller used an unconventional training program that included EquiBrew to turn this $4,000 horse into a $500,000 Group 1 race winner."
