Within 3 months I started noticing a difference and I’ve been using this product for 8 months now and I couldn’t imagine not giving it to my senior horse. I wish I would have known about it sooner. It’s made such a difference in his life and his overall performance. He looks and acts 10 years younger now.

I have a 28 year old arthritic mare. I have tried multiple joint supplements but Actiflex works the best. No more lameness issues, her coat is shiny and she even gained some muscle tone in her rump.

This is the most cost-effective joint supplement that I have found for my senior horses. It has everything that I want in there to help with their mobility. They do move better when on this supplement and it doesn't hurt the pocket book as badly as some of the others on the market. It is a powder, so best to stir in with wet feed or buy the pelleted option.

It Works !

When the farrier notices a difference in the horse, you know the supplement is doing something. It also seems to be very palatable.

Happier horse

She has been on this supplement for a few months - seems to help her joints as she gets older, moving a little easier than she has in the past
