The targeted support for strong tendons, stable ligaments and a supple musculoskeletal system

Take your horse's tendons, ligaments, and connective tissue to the next level with Duval TendiFlex. This targeted supplement is formulated to optimally support the musculoskeletal system —precisely where horses most often need extra help.

Duval TendiFlex is designed for horses that need extra support with their tendons , ligaments , and connective tissue , especially during intensive training, rehabilitation, or rebuilding. The supplement combines MSM, green-lipped mussel, turmeric, oyster shell, plant-based oil, and natural vitamin E—a carefully formulated blend that provides high-quality building blocks for tissue quality and supports recovery, supple movement, and sustained resilience.


Thanks to its excellent absorption, TendiFlex is ideal for horses that become stiff more quickly, react sensitively after exercise, or undergo intensive strain. The ingredients support ease of movement , tendon quality , and the natural resilience of the tissue. The product is suitable for sport horses, recreational horses, young horses in training, and horses recovering from previous strain.

How ingredients work

  • Collagen Peptides (Type I & II)Type I and II collagen form the foundation of tendons, ligaments, and cartilage. These peptides provide immediate building blocks for strong, supple, and resilient connective tissue and support recovery after exertion.
  • MSM (methylsulfonylmethane) MSM is a natural source of sulfur, essential for the development of connective tissue. It contributes to the quality of tendons and ligaments and helps horses that become stiff or sensitive more quickly after exercise.
  • Turmeric (Curcuma longa) Turmeric supports natural recovery after exercise and contributes to smooth movement. It is suitable for horses in rehabilitation or horses that need extra comfort during intensive training.
  • Green-lipped mussel Green-lipped mussel naturally contains omega-3 fatty acids and specific lipids that contribute to joint comfort. It supports horses that have difficulty moving smoothly or that are subjected to heavy loads.
  • Plant-based hyaluronic acid Hyaluronic acid is a naturally occurring substance that contributes to the quality of synovial fluid and cartilage. It supports supple joints and helps horses that require additional support for their musculoskeletal system.
  • Vitamin C Vitamin C plays a role in the horse's natural collagen production. It supports strong connective tissue and contributes to recovery during build-up phases or intensive training.
  • Anise powder– Aniseed supports digestion and makes the product palatable and easy to absorb. This helps horses that are sometimes reluctant to eat supplements, especially during rehabilitation or during periods of heavy exertion.
