Product Summary:

CORTA-FLX® Pellets

CORTA-FLX® Pellets are a clinically proven oral supplement that helps produce joint lubricating fluids to help repair and regenerate damaged cartilage. First of its' kind, CORTA-FLX® Pellets are a unique formulation of micro-sized amino acids plus supportive vitamins and minerals for all classes of horses. Horse Journal stated “CORTA-FLX® produced dramatic results in 3 days” and named it the Product of the Year in 1999. In 2002, Michigan State University researcher Dr. Hilary Clayton proved in a double-blind, placebo-controlled study that CORTA-FLX® dramatically reduced asymmetry in gait analysis testing on horses with degenerative joint disease.

Rated 4.8 out of 5 by 5 reviewers.
Rated 5 out of 5 by Good Product I purchased this to use on my mare when we started jumping. A friend who competes in cutting recommended this brand to me, so I purchased the pellet form. It lasted as long as the label said it would, and definitely seemed to help my mare and her joints. I would recommend this product to anybody looking to purchase a good joint supplement without emptying their wallet should try this. May 20, 2013
Rated 5 out of 5 by Recommended My vet told me my 13yr old Polish Arabian had arthritis in his front left knee; a friend told me to put him on Corta-Flx with at least 50mg HA.... my Arab is back to moving out like a 5yr old again - it works and I recommend it to everyone all the time!!

Rated 4 out of 5 by Happy! my 18 year old quarter horse is on this, i get a lot of people telling me he looks a lot looser than before December 18, 2011
Rated 5 out of 5 by LOVE IT I have had nothing but great results with Corta Flx . My horse eats it without a problem, its affordable and priced nicely. I have an OTTB who I am rehabing with BAD joints. Corta Flx has been a lifesaver! May 21, 2011
Rated 5 out of 5 by Great product I used to use the powder version of this product but the pellets are so much easier. My horse loves these and literally licks the bucket clean. December 13, 2010
