Ulcers are formed by excess acid buildup in the stomach. MagnaGard lines the stomach, acting as a buffer and allows ulcers to heal naturally. Which means your horse can get back to feeling good again.


“The high incidence of ulcers in racing and recently retired off track thoroughbreds and the effectiveness of MagnaGard in treating them makes it a good match. It's certainly helped my three OTTB's!” -Sandy

"I have nine horses on this product. I have noticed a significant change in their hair coat, and attitude while training. They are calmer, and are getting more out of their food. The greatest change is that in one month their ulcers are healing." -Nichole (5-star Amazon review)

"My mare is prone to ulcers and I have found this product to help keep her tummy happy. I love knowing she’s getting all the extra minerals 
in her diet. She holding on to weight great." -Allie

Signs your horse might have ulcers

  • Cinchy/girthy
  • Change in attitude
  • Dull coat
  • Cribbing
  • Loss of appetite / hard keeper

MagnaGard stops ulcers in their tracks and keeps your horse’s gut healthy and happy.

MagnaGard is an excellent source of magnesium and other important trace minerals. Magnesium is a natural calmer and helps reduce stress in horses.

Suggested use

Feed 2 scoops daily (2 oz) in either AM or PM feed. May also be fed 4 hours before event as a calming support and gastric buffer.

Each pouch is a 1 month supply of MagnaGard.

Tips for picky eaters:

If your horse won’t eat MagnaGard, try mixing it in the feed with a good amount of water. You can also try adding some flavor (apple sauce or aloe vera juice usually work well).

Miss Stella

When i was looking for a supplement for my Mare Stella. I ran across MagnaGard I bought the 20 lb bucket because I was intending to really give this a try. She was cranky and irritable with the other horses. Run around with her ears pinned back.. Not willing to work. I started her on this 28 days ago... And what a turn around!! I have a different horse!!! she's loving sweet and Very Willing to Work!! I have fallen in love all over again!! I am a true believer in this product. I will keep her on this for ever.. Georgia S


Love this stuff!
No more cinchy-ness from my horse.
We’ve been using this probably 4 years now.

Helped my horses

I placed my two anxious horses on MagnaGard and their overall appearance and attitude improved. I have since placed my other horse on it, and since he is quite calm, I am interested to see if it improves his digestive health as much.

My horses are happy

This is my 2-3 time ordering this product for all of my client and sale horses. I've been able to reduce the amount of smart Paks and ulcer guard tubes they receive when traveling for shows. It's affordable and the horses have no pebbles consuming the powder or pellets.
