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 154.
    Rated 5 out of 5 by from Excellent product I have used Tri Amino for at least 5 years for several horses. Most horses don't get enough of these amino acids in their normal diet. My horses retain their muscle tone, even when on stall rest. They return to work more easily, with less soreness and faster recovery. If your horse is in training, it is essential. For those who have a difficult time getting horses to eat this - just mix with your choice of senior feed (not pellets - nothing sticks). A handful or two of senior, mixed with the Tri Amino and a few drops of water will prevent your finding the powder at the bottom of the feeder.

    Rated 1 out of 5 by from must not taste too good I bought this with the endorsement of a friend of mine who give it to her horse, but my mare is just tooooo particular about supplements that it would take me a month to tell you all about that. when ever I add any new item into her supplement baggie to be than added to her soaked pellets, I only add alittle at a time, this time I only gave her 1/3 of the dose and after just two days she was over it and refused to eat her soaked pellets and there goes the $$ for her Cosequin, vitamins, calmer etc all down the tube. It is probably just my horse, but if anyone else has a fussy eater, them may want to reconsider getting this product.

    Rated 5 out of 5 by from Love this product! I have only had my horse on this for about 2 months, but I already am seeing what seems to be a bit of an improvement! He has been gaining some muscle and some topline from this supplement and with the extra muscle he got from it is now able to ride round almost all the time when he used to ride like a giraffe because he had so little muscle. I'm very pleased with this product and will continue to have my boy on it for the foreseeable future.

    Rated 4 out of 5 by from seems to be a great product! My horse is 24 and a hard keeper. He also hasn't been in regular work, but I wanted to start back working again. So I put him on the tri-amino because a friend had used it and saw great results. In the month he's been on it he is keeping weight and he is getting muscle back (along with regular work 5 days a week). I am going to continue to use this!

    Rated 5 out of 5 by from Thankful for this product I constantly read about new products and try to do as much research as possible when forming a supplement program for any of my horses. Nobody seemed to know or care for Tri Amino when I brought it up. Given the extra ingredients apart from just the lysine I decided to give it a try. Within 30 days my horse was showing major improvement muscle wise with her toplne especially. My mare has never had health issues, is in a very consistent program, works regularly, is fed quality feed / hay, is on daily wormer etc... There was no reason for her to be in the condition she was in after having two vets check her out. The Tri Amino did not help with her weight , I have Amplify and a proper grain change to thank for that but helped greatly with her muscle, coat and feet! I would recommend this to anyone!- Bethany Unwin from CA

    Rated 5 out of 5 by from Awesome results I recently purchased a horse that is coming back from an emaciated state. She had lost most of the muscle across her top line, her hooves were ridged and brittle, Her mane and tail were ragged and dull. After a little over 30 satyr on Tri Amino, she is building back good muscle, growing out healthy hoof, and her coat and mane and tail are once again Beeson soft and shiny. This supplement has been a key factor in her rehab.

    Rated 3 out of 5 by from Gelding refuses to eat it Unfortunately, as much as my guy needs muscle, he's not inclined to eat this. He leaves it in the bottom of his feed bin. I can't say whether I'd recommend it or not as far as efficacy because he wasn't on it long and didn't eat much of it.

    Rated 5 out of 5 by from I have a 7 year old gelding who I bought this for. Right after I purchased it he was diagnosed with the beginning stage of EPM. He has lost a lot of muscle and I want to start him on it. The problem is he is VERY sensitive to grains, supplements etc. And they make him very hot. He turns from a very mellow horse to a bucking rearing maniac. I currently have him on the Flex Fit support for his joint issues and it is AMAZING! Doesn't make him hyper and has worked wonders for his joints. Can anyone tell me if the Amino Acids will make him hyper/hot?

    Date published: 2014-10-22
    Rated 5 out of 5 by from Results in 20 days! I love this product. I put my APHA stallion on this to help with building muscle. He was put on this about the same time he was put on stall rest. He was flabby at the time he was started on Tri-Amino and put on stall rest, on about day 20 I noticed that his chest was no longer flabby and was muscular and that he had more defined muscle on his legs.

    Rated 5 out of 5 by from Really saw improvement in a short time I bought this for a newly purchased senior gelding. Looking for more muscle tone and topline improvement. In 3 weeks I could see more definition and on top of that, his haircoat is gorgeous! Great price for great results!

    Rated 3 out of 5 by from Did not see a difference with my two horses. I bought this to build muscle on my 18 year old mare as well as my lanky 3 year old gelding. The mare appears to have built muscle in her legs. The gelding appears to be about the same. I'm on the fence about the effectiveness of the product.

    Rated 5 out of 5 by from Works Very Well I used this on a rescue TWH ( 5 years old at the time) and a young quarter horse (4 years old) and have been pleasantly surprised by the results. I'll attach a picture of the TWH, who has shown the greatest improvement.

    Rated 5 out of 5 by from Seems to be working My 5 year old Percheron mare has a noticeably increased energy level (I also started MSM at the same time) whether its the Tri-Amino or the MSM or the combination, I don't know but its very nice. She is normally dull in the summer heat and she clearly feels better during her work-outs. Too soon to really see a difference in her muscle.

    Rated 5 out of 5 by from Helped build muscle quick Been using this for 6 weeks and seeing good results. Have an older QH who came out of winter looking shabby- this has helped build him back up- especially in his hind end!

    Rated 5 out of 5 by from working great for my 24 yr old horse Added this to Buddy's smartpak about a month and a half ago. His top line has filled out. He no longer has the hollow "dips" on either side of his withers. His muscles are bulking up. Honestly I'm shocked a cheaper product could work so well. I recommend it to my sister in law. She just bought some this morning. Great stuff!

    Rated 5 out of 5 by from Great for muscle definition! I started my yearling colt on this almost 3 weeks ago to aid in muscle building. He had already been working 1hr/day and still is, but after starting this supplement I can see where his muscles connect because he is so well defined! He is doing amazingly on it!
