    Probios Powder is rated 4.9 out of 5 by 214.
    Rated 5 out of 5 by from Quality product... This product is an "oldy but a goody" This company has sold this probios product for years- It is effective and economical.I use it for a horse with a sensitive hind gut that had a loose stool. It solved the problem.
    Date published: 2015-09-02
    Rated 5 out of 5 by from Great product I purchased this.product after my horse stepped on a nail and was put on heavy doses of pain medication and antibiotics. We were concerned with keeping the healthy gut flora. My Vet recommended a probiotic. After much research I chose Probios forit's ease of use, competitive price,and quality of the probiotics. I am happy to say my horse is doing great. I have decided to make Probios probiotic powder part of my regular feeding program for all my horses.

    Rated 5 out of 5 by from Great Product! I love this product! My horses can be sensitive to changes in their diet, especially in the spring when the grass first starts to grow in. I always start the whole barn on Probios to help avoid any digestive upset!

    Rated 5 out of 5 by from Very fast acting I just bought this today' and my Mare was colicing and very much down, my Husband thought i could be another impaction. Mixed it with a cup of grain 15 grams, and before i could finish her stall, she drank her water, and I didn't even see her as she was relieving herself. Never been so happy the Vet bills were running me so high, but this stuff really works, and she's staying on it. Probios just saved me hundreds if not thousands or even the death of my best Friend Sapphire..Thank you probios!

    Rated 4 out of 5 by from Better than Proviable We switched two horses (one senior and one with GI issues and ulcers) to Probios from Proviable and have had good results. All our horses readily accepted it and one horse's chronic loose stools (from 3+ months on another probiotic) firmed up within a matter of days. We like the product but the only things keeping us from a "5" are the price and how dusty the powder can be in a light breeze.

    Rated 4 out of 5 by from Helped with meds I bought this for my 32 year old gelding due to his being on long term antibiotic treatment. I felt this product would help with any digestive upsets he could have from the treatment and I believe that it did. Would use it again if needed.

    Rated 5 out of 5 by from What A Difference I purchased this for my horse and have been using it for about 6 months now. I am extremely happy with the results. My mare is 10 years old and her manure is often very loose. This has made all the difference in the world.
    Date published: 2015-04-18
    Rated 5 out of 5 by from Good product I have been using this for a month mainly because one horse is on stall rest. I was concerned about colic potential since he couldn't exercise as usual. The horses seem to like it and it appears to help to maintain digestion. It seems like a relatively cheap preventative.

    Rated 4 out of 5 by from It worked I called Smart pak with a problem of my mare all of a sudden starting to eat her droppings. This is what they recommended and it has worked.

    Rated 5 out of 5 by from Probios seem to be good for my mare I just got a new mare and she'd been on pro bios before with good results, so I continued them. Despite being at a new barn with a new owner and now a new feeding routine, she has done well. And the SmartPak system makes it easy to be sure she is getting what the vet ordered for her.

    Rated 5 out of 5 by from Wonderful product I purchased this for my rescue mare, who has problems with loose stools especially in the colder months. Works great - I would highly recommend it!
    Date published: 2014-12-17
    Rated 5 out of 5 by from Worked for me! My horse has all kinds of tummy trouble, is a cribber, and always dances around when I tighten his girth. We've tried a slew of different probiotic options, but this one is the only one that I can tell is working! He's been on it for 1.5 months and he is gaining weight and no longer gets agitated when saddling. He seems happier overall. **side note, I buy/use the actual canister of powder and scoop it out myself. The live probiotics are very sensitive to heat and die easily. I want as few people touching my product as possible.
    Date published: 2014-12-17
    Rated 5 out of 5 by from He likes it! It must be helping him a lot - he now auditions for the Spanish Riding School (or maybe it's the Royal Ballet) all the way up to the barn. Of course, he won't do any of those things when I ask, but it's great to know he can.

    Rated 3 out of 5 by from Just didn't see results. My mare is the kind of horse that will always have poo on the moist side. I've had her on smartdigest for a while and that cleaned it up great. I wanted to give probios a try but didn't see any results. Gave it a try for 120s before switching back to smartdigest. It did wonders for my dog and reptiles though! My mare ate it right up too which is surprising.

    Rated 5 out of 5 by from Best probiotic for my horse! I tried equerrys and fast track but this is the only probiotic where I saw a noticeable difference in my gelding! My picky boy didn't have a problem eating the full dose or 15 grams, it doesn't have a strong odor.

    Rated 5 out of 5 by from Seems to work Helped to clear up some diarrhea but the powder doesn't stick to pellets well and seems to get left int he bottom of the feed bucket without some molasses or applesauce added.

    Rated 5 out of 5 by from It really works!! I bought this for my 28 year old horse who had lost a lot of weight. Nothing else that I tried helped, but within two weeks I could see that he had started to put his weight back on and now, after a month on Probios, he looks awesome
