Gives comfort to my horse who has ulcers

My horse has no problems with his stomach  and I feel this product is the reason why.
sarah - 07/12/2022 23:56
All horses are eating it. Seen a big difference in their Genaro behaviour in the stable and whilst being ridden.
Guest - 07/12/2022 22:24
Excellent product, used this for a number of years on various horses. Works a treat.
Guest - 07/12/2022 20:08
Fab product, my horse seems to have a Happy GUT.
Guest - 09/11/2022 19:20
Product is palatable horse eats up well. Only been using for a week but so far no problems. Initial problem was unexplained colic and no further problems
Guest - 30/10/2022 19:39
Use on an ulcer horse who hasn’t shown signs of since being medically treated and this is a key part of her management.
Trusted Feefo Customer - 26/09/2022 11:38
My pony is prone to colic and this product helps to prevent it
Tamsyn - 25/09/2022 21:37
Both lids were off the supplement tubs. The supplement powder had escaped and was on the inside of the box. There was also powder residue on the outside of the box. The tubs were about 3/4 full. So I’m guessing they had been thrown around a bit in delivery?
Emma - 25/08/2022 07:49
Recommended to feed by my vet, very palatable and happy horses
Trusted Feefo Customer - 18/08/2022 20:14
Have not used this product very long but I think it is making a difference

Helps to maintain a healthy gut for my horse after recovering from grass sickness
Kay - 13/07/2022 21:07
I have a stressy cob who used to hate being girthed. He has been on gastric comfort for a while and has put on weight, relaxed more and not stroppy to girth
Trusted Feefo Customer - 13/07/2022 20:45
Excellent value for money
Trusted Feefo Customer - 21/04/2022 19:51
Not tasted it myself, but horse eats it
Trusted Feefo Customer - 07/04/2022 18:55
Works well on my horse .  He’s definitely more comfortable and settled
Trusted Feefo Customer - 16/02/2022 21:47
Amazing product that my mare loves to eat
Trusted Feefo Customer - 16/01/2022 18:04
Very good service and delivery
Trusted Feefo Customer - 19/12/2021 19:20
I am only on to my first TUB of Gastric Comfort, but I am sure it is making a difference
Clare - 01/12/2021 19:43
Used for years since my mare being diagnosed.
Trusted Feefo Customer - 22/11/2021 08:03
My horse is very happy and I wouldn’t go without it.
Trusted Feefo Customer - 11/11/2021 07:09
Very good product my mare eats up every scrap and keeps her tummy happy after ulcer treatment
Trusted Feefo Customer - 06/10/2021 20:11
A very useful supplement for horses prone to colic and it helps maximise food value I find so good for underweight horses without having to pile in the starchy cereals.
Trusted Feefo Customer - 15/09/2021 20:44
Works very well on my horse
Carol - 01/09/2021 16:47
It’s early days but the product is palatable and the horse appears happier

Helps to keep my horse’s digestive system balanced after surviving grass sickness
Dawn - 25/03/2021 12:32
No signs of stomach ulcers returning for over a year
Caroline - 24/02/2021 21:14
No measure scoop came with it. As this was the first time I brought the product it was a problem. There is a lot of powder in a cool but mixed in well with the feed and my horse ate her it.
Kay - 15/02/2021 07:23
This product really settles the gut. Good for stressy types and enhances well being
Trusted Feefo Customer - 10/02/2021 19:31
I’ve used Gastric Comfort for some time with my mare who can be prone to colic. She is definitely happier and looks better.
Trusted Feefo Customer - 08/01/2021 08:26
I was concerned that the scoop is quite large and it seemed like a lot of powder being added. I wondered how palatable it would be. However my pony has had no issues eating it all, even with being unable to add water to it (as per the instructions).

It seemed to be making a difference to my pony even before she started treatment from the vet. She was more settled and was allowing me to groom her girth area, which had been a complete "no-no" before.

Happy so far with this product, and the service from Feedmark.
Sandra - 07/01/2021 20:36
Hard to give comments this is my first time using this product.   Only just started to use so difficult to say until we have a few weeks under of belt.
Trusted Feefo Customer - 30/12/2020 19:30
The supplement's are so good they do exactly what they are supposed to.
Carol - 24/12/2020 19:33

Trusted Feefo Customer - 22/12/2020 22:04
my ulcer prone mare has a very careful diet but I always notice the difference with this product, much less mardy and girthy!
Becky - 22/12/2020 10:53
My horse is already looking more comfortable and happier - she has been suffering badly with ulcers and colic

I use this product all the time on my TB mare. She has been diagnosed with gastric ulcers and if I don’t give it to her the is very uncomfortable when putting her saddle on and girth up
Michelle - 23/08/2020 20:18
Superb supplement was recommended for my 20 yr old tb who has a sensitive tummy and it seemed to work wonders in less than a week!
Alice - 19/08/2020 21:38
Can tell the difference straight away. Will be using this forever with my ulcer pony
Trusted Feefo Customer - 12/08/2020 20:21

Trusted Feefo Customer - 11/08/2020 21:44
As far as we can tell it is benefiting our horse.
Trusted Feefo Customer - 29/07/2020 20:34
Great product, really helpful with any pony that has sensitive tummy, also helps with any girthing issues,  very palatable too,
Helen - 23/07/2020 07:17
I have used other products as I thought my tb mare was getting ‘used ‘ to gastric comfort and it wasn’t giving her the full benefits. However she started getting twitchy doing up her girth again and awful when I was getting my stirrups once mounted... so she’s back on gastric comfort and happier.
Trusted Feefo Customer - 18/06/2020 14:26
Our pony loves this product, it really settles his tummy and makes him much more comfortable
Antoinette - 11/06/2020 19:59
Good product. Pony appears happier and ate his feed with the supplement in quite happily.
Liv - 04/06/2020 18:15
The best Ulcer supplement for my horse... we have tried all the other brands available and it works the best.
Fiona - 03/06/2020 21:53
Ponies seem to enjoy it (normally fussy) and it seems to be helping too.
Trusted Feefo Customer - 27/05/2020 21:14
Recommended by my vet for my TB with history of gastric ulcers. She is normally a picky eater but doesn’t mind this at all!
Trusted Feefo Customer - 26/05/2020 09:49
Regularly use this Gastric Comfort, suits our pony perfectly who can have a delicate tummy, makes him much more comfortable and settled
Trusted Feefo Customer - 13/05/2020 20:22

Delivered very quickly but cannot give honest opinion at the moment as only been using it for 2 weeks but no change at the moment.
Trusted Feefo Customer - 02/01/2020 10:48
My horse was treated for Ulcers in November, it's really important she receives a good supplement and management to reduce the risk of ulcers coming back. With success following the Best Flex HA joint supplement I decided to swap my current ulcer supplement to Gastric Comfort. Unfortunately this hasn't worked, some of the previous symptoms of discomfort have come back. I've discontinued use and have gone back to my other product.
Trusted Feefo Customer - 28/12/2019 22:27
Having received a free pack I gave it a go for a grumpy stress horse who didn’t like his belly touched... no noticeable difference I thought.. until I stopped using it! Now he gets it every day. It clearly keeps him comfortable.
Michelle - 27/12/2019 11:42
Seems to have helped initially but she's not doing so well again now
Trusted Feefo Customer - 27/12/2019 08:51
my mare has really taken to this product and shes noticeably less girthy and happier in herself as a result
Trusted Feefo Customer - 18/12/2019 19:36
My horse is looking much more aware and is shinier and doesn’t have a runny back end I recommend this product!

Fedding the Gastic Comfort but my mare has ulcers so hard to tell she is on injections from vet now but think Gastric comfort is making her a little more comfortable
Trusted Feefo Customer - 06/11/2019 14:29
Amazing product, I noticed a difference in just a couple of days and I’m almost a month in and my horse seems so much happier under saddle and in the stable. I could barely get a grooming brush near him before using Gastric Comfort and now he will stand all day to be groomed. I honestly can’t recommend this enough!
Helen - 30/10/2019 10:36
Great product that really works

So I have tried my horse on other digestive supplements, some of which are way more expensive than Gastric Comfort, but I always end up putting him back on Gastric Comfort.
If my boy doesn't have his daily Gastric Comfort, he becomes miserable and bites and his eyes and coat become dull, as he is experiencing discomfort.
I really do recommend Gastric Comfort as my boy has had gastric and hind gut ulcers in the past and this supplement keeps him happy and healthy.
Trusted Feefo Customer - 04/08/2019 08:01
Prompt delivery and good quality product.
Trusted Feefo Customer - 03/08/2019 06:44
Was worried he wouldn’t eat it - but it’s no problem

I purchased initially clarity that was on offer. It was only after I’d completed the order that I remembered that I also needed gastric comfort. I emailed them and the following morning, Sue Meadows rang to confirm my email and add to the order

It does what is says on the tin. Works really well for my horse.

Defenetly can tell if the horse has stopped using product

Nutrition Information

This supplement contains a unique blend of ingredients to help maintain a healthy digestive system and nutritionally soothe the stomach lining. Lecithin and Pectin support the delicate mucosal lining of the stomach, and once ingested, the Magnesium hydroxide forms a soothing gel, helping to coat and line the stomach. Calcium compounds and Liquorice root are added for their alkaline properties helping to maintain normal acid production.


Magnesium hydroxide (35%), Calcium carbonate, Dicalcium phosphate, Wheatfeed middlings, Liquorice root powder, Apple pectin, Hydrolysed wheat glutamine peptides.

Feeding Guide


Weight of Horse/Pony Amount per feed
Up to 400kg ½ scoop
Over 400kg 1 scoop


1 level (50ml) scoop of Gastric Comfort™weighs approximately 32g


Feed with each meal up to a maximum of three times per day to help maintain a healthy gastric environment. 

Gastric Comfort™should be added immediately prior to feeding, keeping the supplement as dry as possible, otherwise effectiveness may be lost.

Avoid feeding large concentrate meals (pellets, mixes and grains). Instead feed little and often throughout the day, especially concentrate feeds. Always feed at least 1.5% of your horse's body weight per day as fibrous forage (for a 500kg horse feed at least 7.5kg of fibre per day). Horses showing signs of excess acid should have continuous access to forage.

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

Gastric Comfort™is a complementary feeding stuff for equine animals. Feedmark uses nothing in the formulation of this product that contravenes competition rules.
