Hydrolysed Collagen Peptides

Studies into the effectiveness of Hydrolysed Collagen Peptides for Ulcers in horses has shown that Hydrolysed Collagen-fed horses had fewer and less severe ulcers throughout the trial. Significantly fewer ulcers were seen after 56 days of feeding. Hydrolysed Collagen also lowered the severity of gastric ulcers in stall-confined horses undergoing stall confinement and feed stress (Hydrolysed Collagen And Ulcer Study).

Gastric Cellular Support

Fermented Legume by Lactobacillus delbrueckii lactis Rosell 187 may help decrease squamous ulcer scores in horses (Fermented Legume Study).

Organic Tumeric

Turmeric in the research showed suppression of the formation of stomach ulcers when fed daily to horses (Turmeric Study).

Slippery Elm Bark

Contains high amounts of mucilage that adheres to the gastrointestinal tract, soothing and coats injured and inflamed tissues, helping them to heal and reducing the likelihood of scarring, as well as drawing out toxins and irritants.

Gelatin Hydrolysate

Gelatin’s short peptides – glyprolines – consist of amino acids of glycine and proline. They protect the stomach mucous tunic from injuries. Glyprolines are easily absorbed in the stomach and remain in the blood for a long time without breaking up. They act not only on the stomach cells but also on the central nervous system overcoming the blood-brain barrier, therefore they help prevent the ulcers caused by stress.

The Difference Between CEN Ulcer Protect and Ulcer Medication

Ulcer medications (e.g Ulcerguard) turn down/block acid production in the horse’s stomach (proton pump inhibitor).  CEN Ulcer Protect does not inhibit the natural acid pump action. It helps protect and heal the stomach wall with high-quality ingredients without side effects. Stomach acid is vital for protein digestion and absorption of key vitamins and minerals such as calcium and magnesium. The acid in the stomach is also important as a barrier against micro-organisms and parasites in the environment entering further down the digestive system. Ulcers in horses can occur in the Foregut and Hindgut. Long term use of ulcer medication can be risky. Evidence from human research that long term use of Omeprazole impacts calcium absorption, which has been linked to an increased risk of osteoporosis where bones become weak and there is the risk of fracture. Short term use would be a lower risk. This has caused some nutritionists and researchers in equine nutrition to question the long term use of Omeprazole in horses. Dr. Juliet Getty – internationally respected independent equine nutritionist, believes that concerns are reasonable because what happens in a horse’s stomach is not that different from human digestion.

“What happens in humans is that these medications not only reduce protein digestion, but they also inhibit the absorption of key minerals and vitamins, such as magnesium, calcium, vitamin D, and vitamin B12” said Getty.

What to feed horses with Stomach Ulcers?

Horses that have or are prone to ulcers will benefit from a high fibre, low sugar and starch diet. This will avoid the gut microbes getting excited and keep the pH at an Ideal level. Feeding long stem roughage will encourage the production of saliva which acts as a natural pH buffer.

Can horse Ulcers heal on their own?

Ulcers present in the glandular and non-glandular areas of the stomach may eventually heal themselves over time. Stress, metabolic complications and diet can all affect the rate and ability of which these ulcers will heal without intervention. A natural ulcer support product like CEN Ulcer Protect may assist with the rate of healing.

Can Ulcers cause back pain in horses?

If a horse is overcompensating in the way it carries itself to avoid pain or discomfort, over time this can cause musculoskeletal imbalances which can present as back pain.

Can Ulcers cause diarrhea in horses?

Diarrhea is a common and clear symptom that there is an imbalance or issue in the horse’s gut, it therefore makes sense that may equestrians link this to gastric ulcers. It is most common to see diarrhea as a symptom of hindgut ulcers. Feeding CEN Ulcer Protect may help support the healing of ulcers and it also contains Prebiotics and Probiotics for gut microbiome assistance.

How do horses get Ulcers?

There are many causes for equine ulcers inclusive of diet, deprivation of feed, stress as well as long term use of medication. Limiting a horses roughage intake can also contribute to ulcers as it reduces saliva production decrease the natural pH buffering effect. Splashing of stomach acid while exercising is a common cause for gastric ulcers, therefore access to grassy hay before training/performance is important.

How to prevent Ulcers in horses?

Having a balanced high fibre, low sugar and low starch diet is the easiest and best way to prevent ulcers. Ensuring you horse has adequate pasture/ roughage, reducing the grain content on the diet and using medications with care are all good preventative practices to help with gastric ulcers.

    Absolutely wonderful product –
    I got a mare from interstate who had to have 3 days travel, she travelled beautifully and arrived in perfect Nick a little underweight from travelling, after giving her a few days to settle in she was so sour toward me and nasty to my other horse and seemed to be losing condition (I had known her before purchasing so I know she was not like this) I thought I’d try CEN Ulcer Protect (I didn’t have a float so taking her to work to be scoped wasn’t really an option) within 2 weeks she was putting on condition, so cuddly and sooky and was a much happier horse, ever since being on CEN shes stayed the same happy healthy horse a year on.
    I also have my gelding on it as maintenance as he is known to get ulcers when in hard work or stressed.
    I highly recommend this product it actually works, plus it’s all natural ingredients ??

    CEN Ulcer Protect is an absolutely fabulous product. One of my geldings has had some long-standing health issues, and has unfortunately been on long-term pain relief. Knowing this would be playing havoc with his gut lining and overall gut health, I bought a tub of CEN Ulcer Protect for him. The results have been nothing short of astonishing. His overall health has improved out of sight, his demeanour has changed from being cranky and unpredictable to being super sweet and soft. He is no longer requiring pain relief, which makes me believe that his long-standing health issues were gut-related. CEN Ulcer Protect has helped him more than I can say, and he absolutely loves it so it must taste pretty good too! I can’t speak more highly of this product, and it is now always in my feedroom. Thank you so much.

    CEN Ulcer Protect great product and cost effective. My gelding was losing weight and looking very hollow stomach was gurgling often with the addition of this product and CEN Oil, his condition and attitude has improved dramatically!

  4. Carolyn Campbell (verified owner)

    CEN Ulcer Protect was recommended to me when I was seeking solutions to very hot behaviour in my 14 year old chestnut TB gelding. Things had gone awry during the drought, despite my best efforts. I am so happy with his change in attitude. He also eats up all his feed now. He never lacked condition but had little issues with his feet and big issues with his attitude prior to feeding him your product. I am SO happy with the change!

  5. Ash (verified owner)

    So far it has really helped my horse that has an ulcer. He is eating better and putting weight back on which is good to see. Can’t wait to see what more progress he can make.

    What can I say about this product other then AMAZING!!

    One of my show ponies suffered from Ulcers, I have previously used medicated ulcer treatments but wanted a more gut friendly (natural product). Withing 4/5 days I noticed a lot of his symptoms had decreased dramatically. I wasn’t worried about getting bitten while doing up girth or while doing his rugs and daily grooming. He’s back to happily eating like a normal horse and not the devil who you wouldn’t dare enter the stable with. we have since finished a course of CEN Ulcer Protect and have kept our show ponies on the maintenance dose while we are heavily training and traveling to ensure keeping the ulcers at bay.

    Thank you CEN for making Ulcer Protect a natural based gastric support supplement that actually works!

  7. Benjamin (verified owner)

    I’ve tried most of the digestive support supplements on the market and can honestly say CEN Ulcer Protect is the best- the results have been amazing, it’s very palatable, and the low feed rate makes it easy to add to small feeds

  8. Karen Curnow (verified owner)

    Nearly finished our 2nd month of Ulcer Protect and there has been a noticeable difference in my horses mood. He is less aggressive and less sensitive with grooming.

  9. Amanda Baxter (verified owner)

    The only supplement that has provided relief and maintained my OTTB ulcers. Highly recommended to all OTTB and ongoing maintenance of, has produced excellent results.

  10. Madi (verified owner)

    Can’t recommend this enough, I have used this to treat 2 different horses with ulcers and without any other treatment saw improvement in about a week and after the full course horses were perfect!!

  11. Tahlia (verified owner)

    Been using CEN Ulcer Protect for a month now and it really seems to be helping. My girl is much happier on the lunge and being asked to trot etc

    Good value for money as well when compared to other similar products, and the tumeric seems to give it a good taste!

  12. Chloe Hampton (verified owner)

    I started to use the CEN Ulcer Protect on my mare after being treated for ulcers. I now use it as a preventative and can’t recommend it enough. Absolutely love it!

  13. Pat Shaw (verified owner)

    I was referred to this product by a friend who had great results with her mare. My gelding has always had issues with his round belly but after a 4 week course, the results amazed me. He is more streamlined and relaxed in his nature. Also his disposition improved and his energy level increased too. I highly recommend Ulcer Protect.

  14. JF Rodwell (verified owner)

    This product is amazing , we cannot believe the shiny coat our horse has now & his improved appetite.
    Even his personality has changed , he is much happier. What a wonderful product to achieve all of this. Thank you !!
