I have used the Cox Vet Lab Acti-Flex products for years for my senior QH. I was getting the powder for a while, but she really prefers the pellets. Because she likes them better than the powder (it's not the fault of this powdered product- she doesn't like ANY powdered supplements) I feel confident that she is ingesting all that she's being given and that it is able to do its work in her joints.

Great price. Easy delivery

I have been using this for years. My 29 and 21 year old both get it every day. They both move freely and the oldest still lets out excited bucks.

I have had horses on Actiflex on and off for nearly a decade. All my horses are older and have varying degrees of arthritis and have all responded positively to it. However, after falling into the trap of "But what if something else is better?" and letting social media get the better of me, I switched to a different, liquid product that was 4x as expensive (more money means more better, right? Wrong.) My mare has fused hocks and a sticky stifle and even with injections the stickiness never really went away on the liquid supplement. After more reading I saw more and more bad reviews of the product and had some concerns so back to Actiflex. We're just about done with the two-week loading dose and my mare's sticky stifle is gone! I will never switch again or be tricked into thinking the grass is greener; the ingredients are stellar, both in dosage and comprehensiveness. I don't think there's a better product on the market that is as cost-effective, and I've tried most of them! An excellent place to start if your horse needs joint support. And don't skip the loading dose - it matters!

It works

My 26 yr old TWH does really good on this supplement. Miss the 5# bucket option.

Easier to get him to eat the pellets, less waste of powder stuck to the bucket.

My old horse looks very healthy. This really made a difference. I've been getting the powder. Now I like the pellets better, Lee's waste

Keeps the old man galloping

He was on this supplement at 17 when I bought him. He’s active more than his age of 25 would indicate.
