Shiny Coats / Coat Health

"My horses love MagnaGard+ so much that they even try and sneak other horses some of it. Their coats look so good along with their manes. They run harder than ever."

"I've seen a huge change in my horse’s condition since she’s been on MagnaGard. Her coat is actually looking so much better now, very brilliant and shiny and she's not as nervous or cinchy as she used to be. I recommend this to all my barnmates!"

Ulcers / Cinchy horses

"My mare has always been cinchy from an accident as a baby and this product has actually made it easier to saddle her!"

"I have fed all types of ulcer treatments. Most were chemicals. Most were liquids that my horse hated. He is picky! I switched to this product and I must say he is doing great! He is slicking out nice and is less bloated."

"The best improvement, is that their ulcers are healing, and they are getting more out of their food."

"We give this to our 16 year old barrel horse and she has really blossomed on it. We suspected she had ulcers but after just a week on MagnaGard PLUS omega 3s Gastric Support her attitude improved significantly and she hasn't been displaying any ulcer symptoms."


"He is no longer acting like a 'typical barrel horse'. Highly recommend!"

"I love this stuff! My horses have been much more calm and their coats are so shiny and pretty!"

"All nine of my horses have changed for the better since being on the product. They are all calmer, and are handling the heat of their grain better."

Magnagard +

I've been using Magnagard+ for a while now and am thrilled with the way my horse looks. He has a healthy, shiny coat and is keeping his weight better.

Highly Stressed Horse!!

My daughter adopted a Mustang....which was brought from her herd in Nevada to TX. She was in holding for a little over a year before we adopted her and then moved to several facilities before she landed where we picked her up. I can only imagine how highly stressful that situation was for her. My daughter is 14 and we discussed some things we needed to do and get before Baylee's arrival. Since she would be in a pen with a 6 foot fence and her stall in the barn, with the pen being on the smaller side, I wanted to make sure we had a gut support additive in place on Day 1. We did our research and came down to MagnaGard Plus. I told my daughter that honestly we would try it, if we didn't like it we would try something else. Since this mare was wild, it was important we had something that could go in her feed. I ordered a small bag of it and she ate it readily along with her feed and hay. We have had her several months with no issues and we are super pleased with Magnagard Plus. My daughter hope to do eventing with this girl some day so I see this being a part of her daily program for the rest of her life!!

Excellent results!

I started using Magna Guard Plus in early March on a 10 year old Paint mare I adopted last fall. She was a very nervous horse. Within 6 weeks, she has calmed down, not aggressive towards my gelding & stands quiet with her head low while the farrier makes her beautiful again.
*She did not like the powder so I mix it with a little unsweetened applesauce. She loves it now!

It Works!

I took on a rescue in January and he was in very poor shape. I noticed that when he ate, he dropped a lot of his feed and would be agitated. He had his teeth floated a day before I got him so I figured that maybe his mouth was sore. As time went on he wasn't gaining weight like he should have even though I added high fat supplements to his diet. He gradually started improving but now he was kicking at his belly when he ate and turning his head from side to side. I was thinking maybe he had a ulcer from being so malnourished and I saw your product on Facebook and decided to try it. Within 2 days of being on it, he started filling out and not dropping as much of his feed and even the kicking at his belly has become much less, which I think now has more to do with flies. Even his attitude has changed, he has become more relaxed. I will definitely be keeping Moose on this and started giving it my mare looking forward to the results with her. Thank you for MagnaGuard Plus, great product.
