My horse really struggled with any change in forage. Any rain on the grass and he would have diarrhoea. The same if his hay gets wet or the grass is lush. With Bio Pro I still have to be careful with how much moisture is in his forage but he has had 7months without diarrhoea.

it works to keep my pony's hind gut healthy.
Trusted Feefo Customer - 04/04/2024 10:34
I've used this before to settle my horses stomach when the grass starts coming through. It's always been very good to get him back to normal and not cow pats.
I'm now also using it for my other horse who is on long term Bute.
Trusted Feefo Customer - 10/03/2024 09:05
Good on the gut  horse's happy
Trusted Feefo Customer - 21/02/2024 22:43
I have purchased Biopro for over five years for my present pony.
Trusted Feefo Customer - 14/02/2024 18:21
Had tried another well known probiotic for slightly watery stools. Within 2 days at 1/2 dose faeces returned to normal consistency.
Trusted Feefo Customer - 09/11/2023 04:32
Didn't help my pony sadly
Trusted Feefo Customer - 05/10/2023 15:07
Brilliant supplement, much better than other well know brands

Keeps my older in in check which rich grass and content
Trusted Feefo Customer - 26/07/2023 16:50
First time using this product and really impressed. I had previously used another well know brand without success, I asked for help online and this was recommended.  My horse was suffering from excess liquid although his droppings were normal. This cleared it up very quickly.
Trusted Feefo Customer - 25/06/2023 10:06
When the grass changes in spring and late summer my TB does cowpats. As soon as he starts I give him this and it soon settles him down.

Biopro is good. I have been feeding it to my horse for a while now. Tried other gut products but always end up back with this
Trusted Feefo Customer - 19/01/2022 21:21
Went from very sloppy poo so started with product and have to say two weeks down the line we are back to normal.
Trusted Feefo Customer - 16/12/2021 16:22
Riri has been on this for years as prophylaxis for grass sickness and to aid in general gut health
Trusted Feefo Customer - 16/12/2021 00:03
Worked well to start with, but tend to give him a couple of days off it to maintain its efficacy. Extremely palatable, both my horses lick their bowls clean when I feed it with their balancer
Trusted Feefo Customer - 10/12/2021 15:13
good product i use all the time
Trusted Feefo Customer - 17/11/2021 19:23
Takes a good 10-14 to see a difference but does help.
Shame it is one of the more expensive supplements.
Trusted Feefo Customer - 15/11/2021 08:05

Trusted Feefo Customer - 05/11/2021 18:31
Seems to have helped my horse
Trusted Feefo Customer - 19/10/2021 09:44
I started using this product after my 18yo Welsh Sec D lost weight in spring, and didn't shed his winter coat as usual.  PPID tests showed there was nothing there, but his droppings were also a little loose. By introducing BioPro gradually, until we reached the stage where his droppings were consistently normal, and not separating him and his Dartmoor Hill Pony companion during summer, he regained weight and his droppings have been normal, on less than the recommended daily dose, ever since.
Trusted Feefo Customer - 17/10/2021 20:50
Always reliable when we change to a new field kn the the grass
Trusted Feefo Customer - 16/09/2021 09:10

I buy the same supplements every month and wouldn’t use anything else!
Trusted Feefo Customer - 27/01/2021 19:29

Trusted Feefo Customer - 21/10/2020 10:29
I've used this supplement for nearly 2 years now. If it didn't work I wouldn't still be using it. Much cheaper than the same thing from my vet. My horse keeps her weight on & doesn't seem continually hungry.

Trusted Feefo Customer - 24/07/2019 19:59
The Biopro has really helped clear up my girls loose stools, I just keep her on a low dose to keep her regular and if we go to camp I up the dose a little to save her getting the trots.

She also has Clarity which helps to keep her airway clear as she suffers from COPD.

Nutrition Information

BioPro™ combines live yeast Yea-Sacc® with the prebiotic FOS.

Horses have evolved to eat a high fibre diet, and this fibrous material is utilised by the horse following the process of fermentation to break it down. This fermentation is undertaken by a number of microorganisms which reside in the hindgut of the horse. The balance of different species is vital in order to keep the hindgut, and hence the horse, healthy, and to allow the horse to get the most from their diet. This balance is easy to upset, and changes in the diet, exercise and management of the horse can have negative impacts on this population, and allow the number of undesirable bacteria to rise. To help keep this delicate environment in peak condition, providing prebiotics (food for the good bacteria), and adding beneficial live yeast in the form of Yea-Sacc® helps to stabilise the population of microorganisms, which allows efficient digestion of fibre, reduces digestive upsets, and helps to maintain optimum digestive health for your horse.

BioPro™ should be fed daily to optimise hindgut health, to older horses, or horses that are poor doers. It can also support horses under increased stress, such as when competing, travelling, or when routine is changing. 


Fructo-oligosaccharide (FOS) (37%), Rice bran (36%).

BioPro™has been formulated to maximise the utilisation of nutrients in your horse's fibrous feed. It is safe to add to your horse's current ration continuously and alongside regular feed and any other supplements. Please allow at least 7 - 10 days for effects to be seen.

Up to twice the recommended amount can be fed for up to 2 weeks if necessary.

Feed supplements should be fed according to body weight. Introduce to the horse's diet gradually, splitting between feeds (when applicable).
