Protexin Pro-Soluble is a probiotic supplement, formulated to specifically restore and encourage normal digestive function for long term use. Highly palatable and can be added to water, food or milk, Pro-Soluble contains naturally occurring microorganisms to promote efficient and healthy gastric conditions. The micro organisms colonise the gut and help exclude potentially pathogenic bacteria.

The 150g pot is marketed for dogs and the 500g pot is for cattle, chickens, calves, lamb, piglets and older birds. The active probiotic organism in both products is the same, and at the same concentration.

Bio Premium/Pro Soluable

Vikki Lockwood

Hi, can you tell me what the difference is between Bio Premium/Pro Soluable. My dog has a very sensitive digestion and wondered which would be most suitalbe. thanks

  • Veterinary Advisor

Both products would be suitable for long term use in a dog with sensitive digestion. Protexin BioPremium is the more advanced supplement and contains probiotics, prebiotics and yeasts helpful to the gut where Pro-Soluble contains only probiotics. I would probably try BioPremium and see how your dog gets on with it.

Can you tell me why this product contains dextrose?

  • Non-Executive Director

I believe this is just a suitable "filler" to facilitate using the product. The total volume of the actual micro-organisms is tiny and giving a suitable amount of them in a dispersible form would not be possible without a "vehicle" to put them in. Dextrose works well for this.
