Sarah Higgins

I have an 8 year old horse who has been particularly sensitive about the girth and also even in the lightest of leg aids. He would shoot off with his back very tense and high and was clearly very uncomfortable despite having a very well fitting saddle. I put him onto GastriVet and even when he has been fresh or in a competition environment, he has continued to react to my leg in a much better way! For competitions, I have also given him the Instant Biotics pre and post competition which seems to be a winning combination. This has given me the ability to ride him much more confidently and as a result, he has stepped up to Prix St George very easily.


Johnathan Bowman

After getting a horse back from a trial, we noticed that she was showing signs of discomfort when being ridden, which was unusual for her. After speaking to NAF, we decided to feed her GastriVet, and wow, within four days she was back to her normal self. I’ve never seen a supplement work so quickly, with such obvious results.


Jo Howse & Mylee

After what was a serious colic incident, Mylee developed hind gut imbalance. Her droppings really smelt, and on examination my vet suggested that I add a supplement containing comprehensive gut support. We put her on NAF GastriVet and within three days the smell had left her droppings and she started to pick up, becoming her old self again.



"One of my horses stresses internally and on the advice of my trainer Bobby Hayler, I put him on GastriVet pellets and I am currently also trialling Magic for competition and heavy training days. I'm very pleased with his progress and his scores are up by around 4%."


Sam Pugh & Tommy

"I started noticing some behavioural issues with Tommy such as stress and tension and after explaining these to my local NAF representative Emily, I was recommended GastriVet. Since being on this amazing product, I have noticed a huge difference in Tommy's demeanour and attitude. He's so much happier in the stable and is much better when travelling now. He is also much calmer and relaxed in his work which has made a big difference in his jumping. I can't believe the difference GastriVet has made to my Tommy and would highly recommend it."


Dr Philip Dale & Happy as Larrie

"I have owned Larrie since he was 4 years old, and he has always been a sensitive horse with a temperament to match! I noticed him starting to dunk his haylage and feed into his water, as well as being uncomfortable whilst doing up his girth. After speaking to NAF, I tried him on GastriVet Pellets and within a week, the symptoms disappeared, the dunking ceased and he has become much for manageable to handle and ride. I would highly recommend this product!"


Amber Fletcher & Smokey

"The NAF GastriVet has been a lifesaver for Smokey! Turning him from being unrideable to winning at hickstead in just three weeks. It has done an amazing job and is very palatable for a fussy thoroughbred. The Show Off shampoo is also a godsend for keeping him looking gleaming."


Rachel Widdows & Arnie

Arnie 16.1hh Anglo Arab 21 yrs old. He is exercised regularly, hacking and flat work training. He has been getting very grumpy about having rug straps and girths done up for quite some time. This winter he was even worse, his groom and I have been dodging his front teeth. On top of this he lost some condition as well. I had been putting it down to the upset of moving yards and his advancing age. However having read that both weight loss and this sort of behaviour can be attributed to ulcers I decided to give the GastriVet a try. Within just a few weeks Arnie seemed like a different horse. Both my groom and I noticed an enormous improvement in his attitude. 5 weeks later he has continued to improve and has gained significant condition, before the spring grass has come through. I am absolutely delighted with the improvement. Arnie means the world to me, all I want is for him to be happy and well. Thank goodness the Gastrivet seems to be doing the trick.


Alfie Bradshaw

"Alfie was showing signs of digestive upset, and the vet confirmed our thoughts by scope in November. He was treated initially with veterinary medication but another scope four weeks later showed the situation hadn't improved. It was proving too expensive to carry on long term so a couple of weeks later we started feeding GastriVet. Four weeks after starting GastriVet and his behaviour has changed dramatically - he is much happier in his stable, being tacked up and is working really well. He will be travelling to Holland at the end of this month and will definitely stay on GastriVet for the move" Emily Bradshaw


Zarla Blue

A big thank you to NAF for keeping Pauldary’s Zarla Blue fighting fit! Back in 2014 Zarla was diagnosed with Gastric issues, following veterinary treatment and advice I chose GastriVet and the results have spoken for themselves. Zarla showed so much improvement quickly once GastriVet was added to her daily feed regime, she is a much happier horse and has gone from strength to strength in training and competition. With such impressive results I have since started feeding Superflex to keep her joints in tip top condition and MPower to support her muscle development. Zarla and I recently won the Scottish Regional Medium R Music Freestyle championship and received a wildcard for the Albion Medium Restricted Winter Championship at the NAF Five Star Winter Championships. A very big thank you to NAF and Area Sales Manager Mary Wastie for your support! Katie James. Photo Courtesy of Equiscot Photography.



Tigga ridden by Tintin Belsham and owned by Suzie Belsham. Tigga was displaying the types of behaviour associated with gastric issues, and while veterinary medication was an option, Suzie wanted to try an alternative so she started feeding GastriVet. Says Suzie, “After one month of feeding the supplement, Tigga was a lot happier in herself and was also much more settled in her stable.”



Sam, ridden by Faye Stephenson, a 17.2hh 6 year old eventer and hunter. Before: After Sam started producing inconsistent results, Faye decided to investigate what may be causing the issues. It was soon discovered that Sam had Gastric concerns. Following veterinary treatment, Faye decided to try GastriVet. After: Says Faye, “Since using GastriVet, Sam is looking and feeling amazing. Normally he would come back from eventing and hunting quite tucked up and would be off his feed and water for a while, however, he now comes back a different horse – looking as well as when he left the yard as well as tucking into his feed, haylage and water.



Hugo, a 16.3h British Sport Horse owned by Charlotte Sherriff. Two weeks ago, Hugo started refusing to go forwards when ridden and then became very upset when under the saddle. He also went off his feed and generally seemed uncomfortable within himself. Says Charlotte “So I stopped riding him, turned him out in the field with ad-lib hay and started GastriVet 7 days ago. Now, after the recommended daily amount for the first week, Hugo is a different horse! He’s very happy and comfortable and I can now put his saddle on without any problems! He is much more relaxed and happy int he stable too. I rode him yesterday for the first time in 13 days and wow, what a difference! He felt amazing, the best he’s ever gone – no naughty behaviour at all! He loved his work and I could tell he was thoroughly enjoying his schooling yesterday! Thank you NAF and GastriVet, an amazing product – I’ve just bought my second tub for Hugo and will be recommending this to everybody! Thank you!”



Harry, a 15 year old ex 2* Eventer owned by Charlotte West. When Harry arrived at Charlotte’s yard he was nervous, constantly alert and on the look out. Consequently, he couldn’t hold any condition, plus he seemed to be showing signs of discomfort. Charlotte suspected some digestive issues and started to feed GastriVet. Says Charlotte ‘We are very pleased with the improvements we have seen since feeding the GastriVet, Harry seems so much more comfortable. I also highly recommend Magic which we feed to Harry.” Self confessed NAF fan, Charlotte, adds “Charles has EnerG Shot and Mud Gard. I also love the NAF Off Citronella Tags. We go through tons of Minty treats and have lots of Pink Wraps in our first aid kit!”



Dexter ‘Odakotah Dex’ has always had an anxious disposition which, when I first rescued him, lead to frequent episodes of digestive discomfort along with a very bad temper. After discussions with our vet and searching for a supplement for what seemed a lifetime, we have found something that actually works! GastriVet is fab, his digestion has improved, and he is so easy and pleasant to be around now. We can finally re-start ridden work now he’s feeling comfortable. Thank you so much NAF. Jodie Stevenson



Bodie (Bodieve Top Flight), an 18hh ID x TB owned by Chloe Durrant. When GastriVet was launched, Chloe decided to try a tub as Bodie’s digestive system could be tricky to keep balanced. Says Chloe “GastriVet worked within just two days, and I’ve kept him on a maintenance dose to keep him regular. He’s much happier, less grumpy and easier to ride! You’re saving me a fortune in not having to rebuild Bodie’s stable every time he gets cranky! I am thrilled with all of your products.”



Bayberry King (Berry) an ex-racehorse owned by Colin and Michelle King. Berry would go through stages where his digestive system would become unbalanced so Colin and Michelle decided he needed some help. Michelle phoned many companies to see what products were available and, after calling the NAF Freephone line, they decided to try GastriVet. After Says Michelle, “Within 3 days we were able to ride him without any of the usual signs appearing after exercise. His appetite has returned and he is back eating us out of house and home. He has been on GastriVet for just 3 weeks and is back to his happy self. He is full of energy and we plan to put him onto the GastriAid once he has finished his course of GastriVet. GastriVet has provided Berry with relief that we can afford, and we are looking forward to having him healthy for many years to come.”
