"I love Actiflex 4000. I feed it to both of my mares- one 20 year old with hock arthritis and one 14 year old with stifle issues. Both horses love the way it tastes. Actiflex 4000 is very affordable for all that it provides. I highly recommend it for any horse with joint problems. "

"Have noticed a big difference in the 5 horses that we are using this on. Especially the older fellow who seems like his much younger self these days! "

"I think this is the best stuff out there for stiff older or over ridden horses I’ve used it on and off for about 5 years now maybe longer. Works right away and they always feel better "

"I have used this for years on my gelding, and if I run out of it I can definitely see a difference in the way he moves and I immediately order more! Well worth the price. I use a scoop of MSM as well when I feed it to my mare, and that combination is a winner for her. I recommend it!"

"I have a barrel horse with osteoarthritis in both hocks, early stages of ringbone, and had even bowed a tendon a few years ago. I can completely tell when she is off this supplement. I tried another supplement that was an "everything in one" type deal, and she didn't move like she usually does. Switched back, and within a week she was back to normal. Great cost from Big Dee's as well! Cheaper than most joint supplement options and this one I've heard and seen nothing but great success!"
