LubriSyn HU 6 Ounce 6-Pack For HumansLubriSyn HU is an oral, liquid form of hyaluronan (HA). HA is the main constituent of joint fluid. LubriSyn HU can help maintain healthy joints by improving the quality of the synovial fluid that cushions and lubricates your joints.Every mammal's joint fluid deteriorates with age and exercise. In fact, the more we exercise, the faster joint fluid can degenerate and the more likely bone-on-bone inflammation will occur. That inflammation leads to arthritis. LubriSyn HU replenishes and restores joint fluid, keeping your joints flexible and well-lubricated.Unlike other forms of liquid HA made from animal sources (e.g., rooster combs), LubriSyn HU is extracted from a microbial source. This method keeps LubriSyn HU free from protein contamination that can cause other HA products to break down and lose their effectiveness.
