New Fluid Action® HA Powder in powder form provides the same great benefits as original Fluid Action® with Sodium Hyaluronate (HA) added for extra support in preserving healthy joints. Sodium Hyaluronate, or Hyaluronic Acid, supports healthy joint function by lubricating joints and helping to maintain structural integrity. It also increases the viscosity level of the synovial fluid in joints. In addition, FLUID ACTION® HA Powder contains Glucosamine, Yucca, MSM, Vitamin C, and many other beneficial ingredients. Fluid Action® HA Powder contains no pain relievers. Some other products contain ingredients for temporary pain relief that do not address the true cause of the problem. In fact, many of these pain relievers can actually make the trouble worse by breaking down cartilage. This is why FLUID ACTION® Powder products work on the cause of the joint problem and not just the symptoms.
