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 214.
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!

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

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.

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.

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.
Date published: 2017-11-07
Rated 4 out of 5 by from Helped an undermuscled senior I started my 23 year old Arab/QH horse on this to help his topline. Within a week I could see a difference over his back and hindquarters - areas that were flat, had started rounding out. After having been on it about 6 weeks he has seemed to have plateaued, but overall I am pleased with it. Functional and cost effective. It does however, smell terrible and I can't imagine it tastes much better. To help ease him into the intense aroma, I started on smaller doses and built up to the maintenance dose.
Date published: 2017-10-31
Rated 4 out of 5 by from Already seeing results I added this to my mare's diet about a month ago, and I'm already seeing results in the improved shininess of her coat. I added it more to help build her topline, but I haven't seen many results there. I anticipate those to take longer, and looking forward to seeing the results in our 2018 show season.

Rated 5 out of 5 by from Nice product I bought this supplement to aid in putting a little more muscle in my geldings top line. It was cheap enough to try and not worry. I am amazed at how nice he is starting to fill out only after 1 month!!
Date published: 2017-10-26
Rated 5 out of 5 by from It works! My horse has been on Tri Amino for about 2 months now. The changes in his muscle structure with minimal exercise is impressive! A great supplement to compliment less than perfect hay to get the added Lysine.
Date published: 2017-09-26
Rated 5 out of 5 by from I bought this for my horses with skin issues. It made such a big difference!! Hair grew back faster and the hot spots on my mare from bug bites cleared up.
Date published: 2017-09-19
Rated 5 out of 5 by from I put my OTTB on this 2 months ago and can't believe the difference! He's never looked or felt better
Date published: 2017-08-28
Rated 5 out of 5 by from Made a difference My young and growing mare has always been just a touch thinner than I would like and has been very slow to put muscle on. We changed her diet 6 months ago to give her more calories, which helped with her weight, but she still didn't have much of a topline despite increased correct work. On the advice of a friend, I added this to see if it would help. We are almost through the first 2-pound bucket and it's made a noticeable difference! She is stronger, more balanced, and she's putting on good muscle in her neck and butt, and back. The Tri-Amino seemed to be the missing nutritional puzzle piece that helped her put on muscle, since correct work and calories didn't quite seem to be doing enough for us.

Rated 5 out of 5 by from Great! My horse has never looked better. His red roan coat has a golden shine, his top line is well filled out and his hooves look great! Very happy with this product. I recommended it to a friend about 6 weeks ago and she has seen the same results in her horse.
Date published: 2017-07-05
Rated 5 out of 5 by from Helps with topline and muscling I use this in conjunction with the Thrive pellets and within two months have notice a huge difference in my mare's topline and overall muscle and tone. Of course, she eats this along with regular training and exercise but the addition to her daily grain has really helped her muscle up and shine.

Rated 2 out of 5 by from Tri aminos Seems like a good product but nothing I do will make my mare eat it. I put it in a syringe with water and give orally but that's a pain.
Date published: 2017-06-19
Rated 5 out of 5 by from Does the trick I'd been looking for a supplement to fill out my OTTB for ages, and this finally did the trick. He's put on muscle and has bulked out considerably since being on this.
Date published: 2017-06-16
Rated 2 out of 5 by from My horse won't touch it I bought this and it smells really nasty. I don't blame my horse for not wanting to eat it. I even tried applesauce and mixing with water and still won't eat it. I wish I could give it better review but it's just too gross smelling.
Date published: 2017-05-21
Rated 2 out of 5 by from no noticeable difference yet Using on hard-keeper mare for approximately 30 days and nothing remarkable

Date published: 2017-04-13
Rated 3 out of 5 by from Just started using this My 25 yr old mare seems to like the taste. It's hard to see results just yet with her winter hair. I will update my rating after she has been on it longer.

Rated 5 out of 5 by from Excellent product I have been using this product for 4 months and can see a huge difference in my horses topline.
Date published: 2017-02-18
Rated 5 out of 5 by from Great for filling out and muscle development When I got my horse back from being in a lesson program for 2 years he was skinny and majorly lacked muscle definition. I stumbled upon this supplement after researching anything and everything I could find to help him start building muscle again. The top picture is from when I got him back in April 2016, and the bottom is from December 2016. He's always had trouble developing a true topline and hind end even in competition shape, but I can tell a huge difference this time around with the help from this supplement. He hasn't been in a full, consistent training program either and he's already started filling out. I started Tri-Amino in August and with the bottom picture being December that's only about 5 months with drastic improvements. So glad I found this supplement!! My only qualm would be I wish it came in pelleted form instead of powder, however that is by no means a deal breaker! I can't wait to see what he looks like come summer!

Rated 5 out of 5 by from Top-line development I used this product previously on an older Arab who had been a bit neglected. After a few months of this with flax and proper exercise he looked like a new horse. Now I'm using it on a paint who was also a bit under-nourished. After just about a month, he looks fabulous. I get lots of compliments on him. His energy and stamina have also increased without him becoming "hot".

Rated 5 out of 5 by from Worked like a charm! I have a small pocket rocket OTTB mare that we have struggled for a year to keep weight on. We have tried multiple feeds and supplements and Omelene 500 grain got us a good start. However, the Tri-Amino from Smartpak was absolutely the final key necessary. She went from dull coat, thin, and just overall poor looking to thick, muscled, and dappled in a month! She is in light work 2-3 days/week and she has absolutely blossomed on this product. I will continue her on it and plan to put my other OTTB on it next month as well!
Date published: 2016-10-27
Rated 4 out of 5 by from So far so good I bought this to help my yearling with some uneven muscle development on his left hip due to a hock injury and this appears to be helping build up some muscle along with exercise. It is palatable and reasonably priced as well. I was looking for something with just amino acids as he already gets other supplements for vitamins, etc. and this product is just a protein powder which is what I needed.
Date published: 2016-10-24
Rated 3 out of 5 by from Not much difference I used this supplement hoping to see some improvement in my Thoroughbred's muscling, specifically along his top line, but never really saw a change.
Date published: 2016-09-19
Rated 3 out of 5 by from Eh, not so sure I bought this for my 28 year old quarter horse gelding, hoping that it would help build up his toplane. He's been on it for roughly one month and being exercised 3-5 days a week (some days ridden and some lunged), but I really can't say that I've seen a substantial difference in his muscling. His hindquarters are more solid for sure, but the topline is about the same as it was before adding in the Tri-Amino. Not sure if the increased muscling behind is a result of the Tri-Amino, work, or a combination of both. However I will say that as an EXTREMELY picky eater, he licks his bucket clean! And for the price, it's worth continuing for another month or two before making a final judgment call.
