Overview

Essential amino acids for protein production

  • Contains 10,000 mg of L-lysine, 5,000 mg of DL-methionine & 2,000 mg of L-threonine
  • These three amino acids must be provided in horses' diets because they can't make them on their own
Support your horse with essential amino acids!

Tri-Amino contains lysine, methionine, and threonine. These essential amino acids must be supplied in the diet, because horses cannot make them on their own. Lysine, methionine, and threonine are also limiting amino acids, meaning that if they are not present in adequate amounts, the body's ability to make protein can be limited.

Lysine aids in bone health and immune function.

Methionine is vital to the health of hooves, and the density of the mane and coat.

Threonine aids in normal immune and digestive functions, as well as supporting muscle mass.

Tri-Amino is rated 4.4 out of 5 by 207.
Rated 5 out of 5 by from Love this Have had my horse on this since I brought him home and it works great. Used as a part of his workout routine, he’s building his topline and filling out more. And it smells so good (at least he and I think so!)

Rated 5 out of 5 by from Adds muscle I bought this product for my OTTB who has a hard time maintaining a "filled out" look. After 2-3 weeks on this product, his butt, chest and neck have filled out noticeably! You won't notice a gradual change, but it seemed that just one day he magically looked beefier (he has not been in work and has just been a cute pasture ornament this whole time). He is still a little ribby so this product did not add overall weight like I was hoping but I am super please at how his muscles have filled out on this.

Rated 5 out of 5 by from Great product! My ottb needed quite a bit of help in the weight and muscle department after being diagnosed with Lyme disease...he faced a serious battle and had gone down hill fast. After his treatment I added this supplement and it has truly been a god send! Along with a high quality grain and hay...he is also on smartstride ultra, smart digest and vitamin e. The tri amino is also the best bang for your buck!

Rated 4 out of 5 by from Easy to feed and palatable I love the product and what it is doing for my horses, I just wish it came in a larger container. I am feeding it to 2 horses and go through the container quickly.

Rated 5 out of 5 by from Saw a big difference! I bought a pony as a resale project that was so skinny and had absolutely no muscle due to lack of work and improper nutrition! In addition to a well-balanced diet, I wanted to make sure to give her the proper building blocks to get her muscles built up properly! Adding this supplement made such a huge difference for her!

Rated 5 out of 5 by from It works! I have been struggling to build up my horses top line and thought I’d try this product. I’m on my 2nd refill and I already see a BIG difference in his top line! I’m thrilled!

Rated 5 out of 5 by from Works very well on building muscle and topline See huge difference in my geldings Topline, butt and neck. This stuff works.
Date published: 2020-05-04
Rated 5 out of 5 by from Put weight on my horse after Lyme disease My mare needed serious rehab after Lyme disease. She list all of her top line and developed kissing spines. The vet felt certain that she would be fine if we could build her back up, so after a month of hand-walking and lunging, we were able to start riding again. We had added some cool proteins to her diet, but she wasn’t building muscle as quickly as we had hoped. My farrier recommended this and in about 4 weeks I started to see a big improvement. She doesn’t have her summer coat yet, but even though her winter coat is in the middle of shedding, it’s soft and shiny. Her feet are doing great, and I am starting to see a lot more top line, and she really isn’t getting sore from working. I was giving her weight builder, and I had to back that off because she is putting in a lot of weight since we started the tri-amino

Rated 5 out of 5 by from Really helps! I have a gelding who loses a ton of muscle after he has been on hay during the winter. The first winter I used it, I saw results in about 45 days. I have used it for 4 winters now with great results
Date published: 2020-02-17
Rated 3 out of 5 by from No difference after 2-3 months just crazy mare! So far no changes :/ I’ve had my mare on this for a month now and I’m thinking about either trying another month or trying something else :/ I have seen no change in body or top line. Only change is that she went from lazy pony mare to spooking at things and acting like a fire cracker! Also I wish was pellet form the powder she won’t eat unless I mix apple sauce :/
