According to a study published by Neuenschwander, H.M. 2019; horses are unable to maintain enough Hyaluronic Acid (HA) in the Synovial Fluid for proper lubrication of their joints.
Looking back to 2004 a study published by Pierce, S.W., Oral Supplementation is "More Effective" than Intra-Articular injections of Hyaluronic Acid to prevent and treat lameness. Horses that maintained a daily dose of oral Hyaluronic Acid showed improvement of all characteristics.
In 2008 the efficacy of Hyaluronic Acid (HA) Absorption, Uptake and Tissue Affinity was evaluated in a study published by Balogh, L, and the findings were astonishing. This study presents the first evidence for uptake and distribution to connective tissues of orally administered, high-molecular weight HA.
Horses given Hyaluronic Acid had a "Significant Increase" in preserving cartilage and an increase in joint circumference with better overall baseline values in a study by Vet Sci, November 2019.
Based on these specific findings, as well as other proven research and countless case studies from horse owners all around the World, Hyaluronic Acid (HA) should be a part of your horses "Daily Nutritional Regimen."
