These days people live a more active and healthy lifestyle. We are encouraged to exercise more, practice sports and move more in general. We take protein for our muscles, NO products for better performance, but we forget that because we exercise more, we put more stress on our joints and skeletal system, and joints can wear out.

SynTech developed a new sophisticated formula for joints, connective tissue and cartilage that improves mobility and keeps your joints flexible.


SynFlex is a high-end formulation for connective tissues that are a component of bone, ligaments (that serve to hold bones together in proper articulation at the joints), tendons (that attach muscles to bones) and cartilage (that connects bones together and is found in joints and intervertebral discs). To upgrade the formula, we added Copper and Vitamin C. Copper contributes to maintenance of normal connective tissues and vitamin C contributes to normal collagen formation for the normal function of bones and cartilage.

Suited for:


  • Sportsmen and women with injuries related to joints, ligaments and cartilage
  • Persons with joint or ligament problems
  • Persons with knee injuries or chronic knee pain
  • Persons with arthrosis or osteoarthritis
