Love this supplement.

This supplement is the best. My 2 arthritic horses have been on it for years, and they are going well. It has all the good stuff in it and is priced affordable.

I’ve been giving my 27 year old gelding a loading dose of this for about three weeks now , and I’m thinking that I’m seeing improvement in his comfort ! I’m guardedly optimizing. I thought , mistakenly , that this was the pellets version , but it’s the powder. He’s an expert at avoiding powdered supplements but he eats this right up . The consistency is sort of like hay chaff and it smells just like alfalfa. Very unobjectionable!

Best Product of It's Kind

I have compared many OTC senior joint supplements, and this one has the best balance and range of ingredients. Plus, even my pickiest horse will eat it.

My horse is 28 going on 29 in a few months. She is able to move more freely since I started het on Acti-Flex Senior. Occasionally she will run around the past
