Formulated with highly bio-available hyaluronic acid (HA), it supports healthy cartilage, connective tissue, and mobility, promoting smooth, extended movement for optimal performance or improved quality of life.

Competition-Compliant Formulas

Our product is designed with competition-compliant ingredients, ensuring worry-free use for trainers and owners.

Support for every stride, every day

Flexify-HA is ideal for everyday joint care or to provide enhanced support during high-performance events. As horses age or take on intense workloads, their joint fluid diminishes, leading to discomfort and stiffness. Flexify-HA encourages the replenishment of joint fluid, easing joint friction and allowing your horse to move more freely.

The combination of hyaluronic acid, MSM, and Vitamin C helps improve joint fluid, maintain flexibility, and support cartilage, allowing your horse to move comfortably.

Formulated in the most competitive horseracing country in the world—the United States—Flexify-HA provides a competitive advantage at a fraction of the price of other supplements. It’s the joint support you need to give your horse the best shot at the photo-finish.
