TamaFlex™-A novel nutraceutical blend improves lameness and joint functions in working horses.

Background: Lameness is one of the major causes of reduced physical performance and early retirement in working horses. TamaFlex™ (NXT15906F6) is a standardized synergistic anti-inflammatory botanical formulation containing Tamarindus indica seed extract and Curcuma longa rhizome extract at a 2:1 ratio.

Methods: We conducted a 12-week single-center, randomized, blinded, placebo-controlled trial demonstrating the efficacy of NXT15906F6 in horses with lameness grade 2-4 on the American Association of Equine Practitioners (AAEP) scale. Twenty-two lame horses were supplemented with NXT15906F6 (2.5 gram/day) or placebo over a period of 84 days. Improvement in lameness over placebo was the primary endpoint, and changes in the levels of rheumatoid factor (RF), anti-nuclear antibody (ANA), and anti-cyclic citrullinated peptide (ACC-peptide) in serum, and pro-inflammatory cytokines including interleukin (IL-1β and IL-6), tumor necrosis factor-α (TNF-α) and prostaglandin-E (PGE ) in serum and synovial fluid were the secondary endpoints.

Results: NXT15906F6 exhibited significant relief from lameness in a time-dependent manner. NXT15906F6 also reduced levels of ANA, PGE , IL-1β, TNF-α and IL-6. Moreover, NXT15906F6 supplementation is safe and tolerable in alleviating joint pain in lame horses, and protects the joints from further degradation by reducing pro-inflammatory mediators.

Conclusion: NXT15906F6 significantly reduces the lameness during walking and trotting, leading to an improvement in their joint flexibility, health, and working performances.
