Works very well.

I've been using the powder for several months now and it seems to help my horse's joints. He'll be 28 next month.

Not a fan of powers.

I do prefer pellets for feeding. I like the product, had all three of my horses on it. Roan Dog went over the Rainbow Bridge this spring, down to two horses now

Immediately Caused Major Diarrhea :(

Thought it wouldn’t be any different than the liquid I have been using but there’s something in the Powder version that didn’t sit well with my horse.

Love the product and have used it for a while, but in pellet form. It works really well on my 20 year old mare, but the powder is hard for her to get to as she doesn't lick the bottom of the feed bucket. Will need to go back to the pellets

I can tell a huge difference in my mare already after just a couple of weeks! And my gelding’s colicky hocks are no longer clicking. Extremely fast shipping on Chewy’s part and very reasonable pricing.

The same as pelleted

I prefer the pellets, but was having an issue getting in pelleted form. The will due for now. My one horse will eat anything, the other really prefers pellets.
