My horse has been havingnissies lately and his fecal water syndrome was getting worse and worse. It cleared up while on ulcer meds and came back with a vengeance. A barn mate recommended to try this and see if it helped and it has immensely. His issues are mostly gone. We've gone from me having to hose his rear end off every day to just brushing it off. So glad I tried it.

This product is awesome! I have tried many gut supplements and this one is top of my list. The only other one close to this is Gastro Phix and frankly I think this product works better and bonus it costs half as much. My gelding does need 3 cups a day but boy does it work well and quickly. Within an hour of dosing I can tell he feels better. I am so glad I tried this and won’t feed anything else. I highly recommend this product!

My horse does not enjoy the flavor

I've seen him calm down with this gastric care supplement, but he really does not like eating it. He often picks at it and sometimes refuses to eat it entirely.

We started this supplement following an emergency colic surgery as my 7 year old TB was put back on stall rest for three months. We figured with the stress of being back in a stall anything we could do to support his gut health was a win. He had just been greenlighted to start full conditioning following a suspensory injury the week before his colic surgery. The supplement is very palatable and my guy didn't mind it added to his daily meals at all. Because we used it to support his gastric health after a colic, I don't have a baseline.

The Blue Seal Sentinel Care Gastric Supplement is perfect for horses that are under stress from training or travel. It is in pelleted form and can be given up to four times per day. It includes bio-available marine sourced calcium to help maintain normal gastric pH as well as butyrate and zinc for gut tissue integrity. My horses will eat this straight out of my hand. I give them some prior to exercise and stressful events such as trailering.

An affordable gasto intestinal support feed. Great quality pellets that my horse will actually eat and approves of the flavor. I would say highly palatable. So yes, great quality, great flavor but I like the bag. Easy to open pull string, clear instructions and ingredients. He doesn't have any issues, but who doesn't need gasto-intestinal support. I also prefer to give his pr

I took this sentinel care gastric support horse feed to the barn where my horse is boarded, and offered it to six different horses who are on a diet to support a healthy gut. None of the six were interested in this feed. We were disappointed and would not purchase it as a result.

I was excited to try this, but with the recent issues from ionophore contamination in horse feeds leading to the death of over 80 horses, I decided to contact the company first. After two emails, they still have not gotten back to me, and there's no info about their ioniphore safety on their website. Without confirmation, I will not use it. also, a feeding rate of 5lb/day for a supplement is extremely high and not worth it IMO.

Ok so this is one of those products that you can't really tell much about term but adding this to their feed and they are eating it. Texture and smell are good. Both my 25 year old horse and 9 year old donkey are on gut health. Price isn't bad when looking out how long a bad lasts if used as directed. Gonna keep them on this and will update in a few months.

While gastric supplements will take a while to show any visible improvement in the horse, I can say that my normally picky Thoroughbred mare eats this right up when it's mixed into her normal feed. I don't know if it's tasty or if she just doesn't notice, but either way it's nice to have a supplement she doesn't turn up her nose at.
