I went to their web page.
They are asking $56 for two tubes of the probiotic - $56 for two tubes
They want $84 for FIVE pounds of product for metabolic horses.
For that kind of money, their products should be NASC approved and I don't see the seal anywhere on the website; although I could have missed it. NASC - National Animal Supplement Council
I dunno. I am the first one to step up and say buy products that are pure and free of fillers, even though they cost more money. But this is ridiculous.
This isn't even a pre-probiotic; it's advertised as a probiotic.
My opinion is to keep looking
Or if you don't have the time, take a look at Med-Vet Pharmaceutical's probiotic. All their products carry the NASC seal and this is .18 cents per serving. Probiotic V™: medvetpharm
I buy their products thru United Vet Equine.
I use the Hyalarin/Boswelia and Anti Carb for my metabolic horses; one of which has pretty bad hock/ankle arthritis. Probiotic V
Hope this helps
