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 10cfu/ml (109cfu/100ml 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.
