Dynavyte Microbiome Support Probiotic for Horses

Notify Me When Available
Want your horse to be healthier?

Microbiome Support is a naturally brewed and fermented probiotic that is the flagship of the Dynavyte range. It contains Bacillus subtilis, one of the most studied probiotics in the scientific world

Bacillus subtilis supports good bacteria within the intestines and suppresses bad bacteria promoting a healthier gastrointestinal tract. The Bacillus subtilis natto can form a spore when conditions are unsuitable and therefore survive where other probiotics die.

Microbiome Support has many advantages over other probiotics, including a prebiotic (food source for the probiotic), making it a new category of combinations called a synbiotic.

Helen Doessel (Brisbane, AU)
Dynavyte Microbiome Support

Love this product. I have an older horse (24) and a younger who is 7. They both get this product in there wet feed. My old girl can get colic from eating anything different so I use this to keep her gut health as good as can be. I normally buy the 10L and it lasts for months. Highly recommend. Great price too from vet n pet direct. Quick delivery and the service is always prompt. Thanks guys for caring to get things out as soon as humanly possible.

I have been using this product for years. It keeps my horse happy on the inside and the great health shows on the outside. She has dapples galore and a gorgeous shiny coat. Vet'n'Pet Direct have great pricing and quick delivery. I have never had an issue with any of my orders so I highly recommend.

Easy to administer probiotic

I started using this product when I bought home a very underweight mare. To assist her gut back to health. She started putting on weight in days rather than weeks and her gut health improved within the first few days of use. I still give my horses a few doses if they have had antibiotics.
