The best thing about EquineCare Probiotic is it contains hardly any ingredients. Unless you are counting billions of beneficial microbes, yeast and water which create an environment the pathogens can no longer survive in. It is natural, organic and non-toxic which makes it completely safe to use on your animal. It is also non-swabbable which is good news for racehorses. In this day and age with antibiotic resistance occurring at an alarming rate, it is reassuring to have a natural, safe and effective alternative for infections of this nature.
