I know that most don't believe in feed through supplements and most say injectables but I was wondering as my coming 2-year old will be getting started this year (as long as she doesn't keep trying to cut herself open- facepalm) what does everybody gives their young horses? Or do you just let good feed do the work till they are in more consistent work/hauling? Want to try to make sure she stays sound. (Without putting her in a padded room) 

I didnt have mine on a supplement until she was in training. I had her on Corta-Flx as a 3 year old and then I switched the Actiflex pellets last year. She is about to be 6.

I have everything on MVP Exceed 6 Way. I just give half the regular dose when they're young & not in heavy work. 

all of mine are on Grand Meadows Grand Premium Plus. 

Myristol Pro!  

But I don't start mine on anything till they are hauling... but my training is not intense either... lol

I should say my older horses that are still hauling every weekend (15 and 24) are on cetyl m most of the time. And that has helped both a ton. I just want to keep her as sound as I can. Although young horses like to hurt themselves. 

The very best, most surefire way to keep your young horses sound is to NOT ride or work them as two year olds.   Despite the industry wide popularity of treating horses as disposable commodities, if you love your colt and want an animal to durably prosper, let his vulnerable soft baby bones mature. 

Thank you for your opinion! Everyone has an opinion on when to start or work a horse. She is not going to be running by the time she's 3 but she will be basic started as a 2 year old and then let mature or take on some easy trail rides either ponied or ridden. And that's if I feel she's ready to be started physically and maturely. Trust me she's not just another horse and being that I also have a 24 year old (who's been with us as a family for 16 years) who is still running every weekend I do take care of my animals 

Personally, as you mentioned in the original post, I'm not really a big believer/user of feed through joint supplements. I think in most commercial feed through joint supplements the efficacy is minimal. However, I was looking into GLC 5500. Have heard great things about it. Is anybody a user or former user that can comment on this?

My barn owner has a retired reining horse on the GLC 5500, he does lessons for young kids now, walk trot & very limited loping. He's been on it since summer, she still moves awkwardly stiff just the same as before. The injections he had gotten before that did a much better job. I expect her to just go back to injecting, she doesn't feel like there's any difference n him. It also may just be him, i don't know what was done with him. He doesn't have great brakes and he doesn't know how to spin more than half a mile an hour, I'm not really sure what kind of reining career he could have had.

I do agree with feed through's generally not being very effective. I do the Exceed because my vet and I have gotten actual documented results from it & he's the biggest skeptic of them all with feed throughs. I still do joint injections though annually for some of them. But I used to try everything under the sun for joint supplements & my horses still came to the vet for injections with completely dry joints so clearly nothing was doing any good lol 

We don't like to start at 2. The earliest we did was our stallion. He was started in Sep and was born late May. Just had a quick easy 30 days put on him. 

GLC-5500MAX is awesome as a preventative. 

If she can handle it that will be all she's getting is 30 days and it will be later in the year. She's had a ton of groundwork and has been handled so it won't be much to get her started. There's plenty of arguments on both sides of the argument on when to start a horse and I have seen both horse started older and started younger. 
thank you to the rest who understood the question!! I was just thinking out loud when I posted

I don't feed joint health, I'd prefer to inject. If she's not gonna be heavy worked, I'd worry more about an ulcer preventative while she adjusts to her new schedule than joint maintenance. I'd revist a joint supplement later into her 3 year old year as work gets harder. But thats just me!

Exceed 6-Way would cover the joint aspect & the gastric care aspect, 2 birds with one stone. Or really 6 birds with one stone, it has many other benefits :) 

I love OCD pellets. Worth every penny.
