I use cosequin by paw and flax seed oil. Would never go without it
I used bean mill it put weight on my horse and it keeps them healthy
i use normal pellets and then on top of that i use previcox and some smartpaks (smartshine, smarthoof, smartflex, & smartbugoff (summer)).
I use MSM and glucosamine and I see a huge difference on my mare who is 21 :)
Sunflower seeds and Flax!! Its so great for their coat and there immune system! You can definitely look it up for more info! But trust me they are both so good for your horse! Hope this Helped!😊
