Amazing Ingredients!!!

I’ve only just started feeding this to my mare with suspected mild arthritis but I just have to say that for the price the ingredient list is amazing. The fact that Bioperine(helps the body absorb nutrients) and Super Oxide Dismutase(fights oxidative stress and inflammation) is in the ingredients even before water is impressive. As an added bonus there is now collagen added which I was not expecting but definitely thrilled about! I’m excited to see how this product transforms my mare’s movement and mobility!

Really Works for my Dog

Got for my old Newfoundland Border Collie mix. We give him a quarter ounce a day mixed in his food. It is kind of thick and weird pina colada flavor. Two weeks later and he is climbing the linoleum staircase on his own choice. I can't remember the last time he did that. We were planning on making a ramp for our two large stone stairs, but this may give him another year. I may start taking it,

Excellent joint supplement

My horse really likes this. It smells like coconut and has high levels of key ingredients. He's 17 and moves great! I think it's one of the best and isn't expensive.

Bottle White cap

This is great. Works well. Prefer the one in the white cap though. The black cap bottle is darker in color and stronger in flavor. Hope my next order is the lighter color.

Love love love!

This is the best joint supplement I think I’ve ever tried! My younger guy was much more flexible after a little over a week and my older one, I haven’t heard any clicking since keeping him on it consistently!

love this product

I've been using Actiflex for 8+ years and I absolutely love this product. I use to give my horses monthly injections for their joints and this product has changed that. They get this every evening on their food and they love it!
