Oh, my appologies - do not use SmartGut if your boy does not have ulcers. My fellow does, being a TB and they are more "high energy" than other breeds - having him scoped showed ulcers in his digestive tract, so my Vet had us start SmartGut after doing a big treatment of Gastro Guard.
Do not start an ulcer treatment, unless you have your horse scoped to ensure that they are there or not, or your horse shows alll the signs of ulcers.
That is just the combination I have him on, to correspond with his issues.
If you are concerned that your horse may have ulcers, without going through the expensive treatments and tests to see if your horse does have ulcers - you can step up your digestive treatment from SmartDigest to SmartDigest Ultra.
SmartDigest just targets digestive issues, where SmartDigest Ultra targets both digestion and ulcers because it has 2 more ingredients in it, including
L-Glutamine and Solube Fiber.
