Product Overview

Essential amino acids for protein production

Tri Amino™ Powder provides the essential amino acids to help maintain strong muscles, support a healthy topline, and assist in protein production. Essential amino acids means that if they are not provided in adequate amounts, body productions will be limited. As horses, lysine, methionine, and threonine are not produced on their own and therefore can be supplied in their diet. Lysine and threonine are the most likely to be deficient and if found in low amounts can limit the body’s ability to build muscle. A deficiency in methionine affects muscle function and synthesis of structural proteins such as as hoof, connective tissue, and hair health. Lysine and threonine also aid in immune function and is involved in bone health. Tri Amino offers these protein building block in their pure forms, working together to support your horse’s overall body condition and create ideal protein levels for muscle building and function.

Made in the USA.
  • Muscle support for protein deficient diets
  • Supports hooves, bone health, immune function, connective tissue, mane and coat

Tri-Amino is rated 4.4 out of 5 by 239.
Rated 5 out of 5 by from Tri Amino my horse is doing very well with this addition to her feed as she has gut issues and these nutrients seem to help her digest better and keep her weight on .

Rated 5 out of 5 by from Great bang for your buck! I love this supplement for my ex-Amish driving horse. Since I am asking him to move in a very different posture, I feel it’s important to give him the building blocks to help him grow these new muscles!

Rated 5 out of 5 by from very palatable for the horses I will continue to buy product. It is shipped with in days

Rated 5 out of 5 by from Great company! I haven't been using this product long enough to see if it helps my mare, but all the products I've gotten from Uckele have been of high quality. I also like that they ship right away.

Rated 5 out of 5 by from Senior horse owners I've been using this on my 24 year old QH gelding who was losing weight last year on his regular feed and hay. I supplemented his diet with soaked timothy/alfalfa hay pellets and Tri-Amino. He gained weight and his topline filled out. He looks much younger and healthier and feels it too! I have a herd of horses and can't afford the pricier supplements, so was really happy to see how this less expensive one works so well.

Rated 5 out of 5 by from Great product and fair price I started my 17yr old QH gelding on Tri-amino to help him maintain/support his topline as he ages. I wasn't expecting to see results so soon since he's not in work during the winter, but I've noticed he looks fuller through his withers (used to have a bit of a dip behind them) and also over his hindquarters. I even think his mane and tail are benefitting. I cant wait to see how he looks once he comes back into work and is doing exercises to help build muscle while on this product.

Rated 2 out of 5 by from I haven’t seen a difference I’ve been using it for a couple months on my quarter horse gelding, I had hoped it would aid in adding muscle on the top line and make his mane grow. I’ve seen no improvement. On the plus side he eats it no problem.
Date published: 2019-01-30
Rated 5 out of 5 by from Noticeable Tail and Mane Growth Bought this to assist with muscle/top line development. Not only have I seen an increase in my gelding's muscle development, his mane and tail have grown noticeably. Others in my barn have even commented on the thickness/growth of his tail. Results were within 1 month.

Rated 5 out of 5 by from Tri Amio A great way to get important amino acids to my horse who has very limited access to fresh forage.
Date published: 2018-11-20
Rated 4 out of 5 by from Good value I have only been using this for a couple of months but I think it is beginning to show the effects of use. My quarter horse has some issues that we are working with the vet on but I think this is helping with muscle and soft tissue.
Date published: 2018-11-19
Rated 5 out of 5 by from Well worth the price! I added this to my SmartPaks a month ago and I can see my senior horse’s top line filling in. He’s also gaining more muscle & looks better than ever.

Rated 5 out of 5 by from I love tri-amino My senior horse has been on tri-amino for years. It really does help with building up his topline and other muscles.
Date published: 2018-10-21
Rated 5 out of 5 by from Gave my mare a Topline! I bought this a month ago and since using it, my mare has gained a topline and muscle behind her wither.

Rated 4 out of 5 by from Great product! It improved my pony's muscle tone No problems feeding Tri amino with sweet feed.

Rated 5 out of 5 by from Top line! This is the best supplement, for their top lines. I've tried other amino acid products, they just don't cut it. I've been top dressing my youngsters mashes with this since they were about a month old. All of their top lines are strong! I recently got a horse, with good conformation, however, his top line is a lil weak, ive been giving him Tri Amino for almost 2 weeks, and I can already see a change. The muscles are starting to fill in. Thanks Uckele.

Rated 5 out of 5 by from Tri Amino 5lb my horses topline is improving with the Tri Amino. She has been on this for 6 months and it is helping.
Date published: 2018-08-15
Rated 5 out of 5 by from Great suppliment I like that it's palatable for my horse in his grains because he can be fussy with what's in there but he eats this right up . Also I find it has been a great addition to my horses work out regimine helping him get fit .
Date published: 2018-05-15
Rated 5 out of 5 by from I can't believe the difference I have gone through three of the 2lb tubs of this and I can see a huge difference in my horse. Before it didn't matter what I did--proper diet and exercise was NOT fixing his topline. He looks amazing now and he's clocking much better times in the arena. I could not be happier. This product isn't even expensive! I added a before and after pic--in the "before" he's so lanky, his belly sticks out, and his topline is horrible even though I was exercising him and feeding him quality feed all by the advice of my vet. We then decided to add this supplement and the "after" picture was taken yesterday during his bath. No more belly poking out and finally some definition along his topline. We still have some work to do to get him looking perfect, but this is a great start. Also, it smells a little weird but he eats it just fine.

Rated 5 out of 5 by from Great for toplines I have a gelding that lost a lot of muscle tone especially along his topline for unknown reasons. I decided to try this supplement and it has done wonders for this horse. It took approx. 6 weeks for him to regain what he had lost plus gain muscle overall. This is one of the most reasonably priced supplements to feed as well.

Rated 5 out of 5 by from Love This supplement has helped my horse build muscle and have an overall healthier body condition.

Rated 5 out of 5 by from Topline! Put my mare in this who is recovering from kissing spine surgery and tendon tear. She has built up so much muscle and has a top line for the first time ever!
Date published: 2018-01-17
Rated 5 out of 5 by from Helps a lot! Are use this to help my Haflinger gain a little more top line as he was switched to a feed that he doesn’t get much of and I think therefore wasn’t getting enough protein compared to the old feed he was getting (oats and sweet feed, but that’s no good for hypothyroid or horses prone to tying up so had to make a change) so the top line was wasting a little bit just a month of this really help to get the muscle on

Rated 4 out of 5 by from so far so good used it for a month on 2 horses, one who was a body score of 2 & 1 who needed more muscle. both have showed improved muscle tone, as well as the body score 2 has shown quicker recovery.

Rated 4 out of 5 by from It's Working!! I have a PRE mare that is very fit and very lean but needed topline and hind end development. I have added Tri-Amino to a 3rd feeding and she has begun to fill out. Her mane and tail appear to be thicker also. The product is very smelly but it doesn't seem to bother her . I will continue to use
Date published: 2017-11-16
Rated 4 out of 5 by from Beginning to see changes in top line. After my mare foaled it seemed that her top line had disappeared! It was recommended to add lysine to her diet to aid in the utilization of protein. I decided on Tri Amino because it had the three amino acids that aren’t synthesized in the body. It seems to be working but like many supplements it needs enough time to show true results.
Date published: 2017-11-11
Rated 1 out of 5 by from Made horse very hot Had to stop giving it after a couple weeks because the horse got so hot. I didn't think it could be this because amino acids shouldn't have that effect, but I stopped giving it because I didn't know what else to try, and she was able to relax and focus again within days.
Date published: 2017-11-09
Rated 4 out of 5 by from Good for recovery I started supplementing my mare with this in preparation for our 3rd endurance ride. I noticed a huge difference in her recovery time. It should be noted that this stuff smells terrible, so you might need to doctor it for picky eaters. Wish it came in pellet form.
