When horses are pushed through active show schedules, competition, or sustained training demands, Yin becomes gradually depleted, manifesting as generalized weakness, especially in the lower back and limbs. This formula replenishes Yin, restoring the foundation that sustains athletic performance and overall health. Available in traditional powder (500g, 900g, 1200g) and Flax Plus (30-day and 60-day supply); the Flax Plus format includes a six-tablespoon scoop. Dosing varies by body weight and health condition; your authorizing veterinarian will provide specific guidance.

The athletic horse is inherently Yang-dominant, and sustained performance gradually depletes Yin. Kidney Yin deficiency leads to skeletal weakness, especially in the lower back and legs; Liver Yin deficiency affects Blood quality and generates internal heat. Long-term Yin deficiency causes fatigue and increased susceptibility to dysfunction. This six-herb classical formula (based on Liu Wei Di Huang Wan) directly replenishes Yin while clearing deficiency Heat, providing the restorative foundation the athletic horse needs to sustain peak performance.

When horses are pushed through active show schedules, competition, or sustained training demands, Yin becomes gradually depleted, manifesting as generalized weakness, especially in the lower back and limbs. This formula replenishes Yin, restoring the foundation that sustains athletic performance and overall health. Available in traditional powder (500g, 900g, 1200g) and Flax Plus (30-day and 60-day supply); the Flax Plus format includes a six-tablespoon scoop. Dosing varies by body weight and health condition; your authorizing veterinarian will provide specific guidance.

Kidney Yin deficiency leads to skeletal weakness, especially in the lower back and legs; Liver Yin deficiency affects Blood quality and generates internal heat. Long-term Yin deficiency causes fatigue and increased susceptibility to dysfunction.
