Let customers speak for us
from 57 reviewsI've only just started tapering Larry onto the Protek GI so I can't speak to the product itself as of yet but the customer service was amazing. I had many questions and they were extremely responsive and informative with each of my emailed questions. We haven't worked up to a full dose yet but so far my picky eater has been eating the product without issue. Hopeful for great results for my ulcer prone guy!
My horse is very picky but soaked with her grain and a little water and she licks her tub clean. She's been on it for about 2 weeks and so far I've noticed less fussing on the crossties, less yawning and much more comfortable under saddle.
This is the best ulcer/gut supplement on the market. Would rather use this than ulcergard.
I am so thankful and happy that my vet recommended this product to me. It is amazing. My horse was having reoccurring ulcers, was on ulcerguard for 5 months straight and was still having colic issues. I started this product and I was able to take him off ulcerguard completely and I’ve had him on it for about a year now with no signs of ulcers. My horse also loves it and he’s pretty picky!
My 6 year old struggled with ulcers that would just come right back once treatment was finished. With ProtekGI, we’re 4 months ulcer-free!
Protek GI was recommended to me by Dr. Ben Sykes during a virtual consultation I had with him about my mare’s ulcer challenges. Once he explained how Protek GI works, I realized that it offered much more than the multiple supplements I was currently using. I’ve seen amazingly fast results in terms of improvements in her under saddle performance, and she seems much more comfortable and happy. She loves the taste, I have streamlined her feeding program and with autoship, I’m certain not to run out.
My 2 horses were struggling this Fall with stomach discomfort. Since starting Protek GI they are feeling much better.
My horse is feeling so much better and is looking amazing .I’m on my second tub ... Thank You
If you are looking for a great product that helps with Ulcer prevention, this is one of those, that I would really recommend.
My mare has been suffering from chronic ulcers for 6 months. As soon as we finish a 28 day omeprazole treatment and do the suggested weaning off, the ulcers start coming back within 24 hours. This product was recommended by my vet. We tried it and I saw a difference in my horse’s attitude with the very first dose. I was impressed. She perked up and got her pre-ulcer energy back within a week. I started adding it to my other horses feed with the same response. It is a powder that they actually eat and lick their bowls clean. I have high hopes for long term results with ProTek GI. I’m telling horse owner I know about it.
Excellent product, is helping to maintain an ulcer free stomach once treated. The horses I have it on are gaining weight better and appear to be much more comfortable.
Put my gelding on this for a grade 3 ulcer. He has never been better under saddle! I’m keeping him on this Several other people in the barn have also been using it. Game changer for the ulcer prone horse!!
We've been scoping, GastroGard, and using the high end supplements but only inching toward better gut health until we tried ProTEK GI
A real game changer. Your horse will thank you and your competition results will improve!
This is a great company to work with. Every horse is different and they understand that. Very responsive.
Been using PROTEK GI for three months now for my horse's pyloric ulcers. Best results to date. We've eliminated Misoprostal, eliminated Assure Guard Gold, and have seen far better results with PROTEK GI.
