Hyaluronic Acid is a compound present in every tissue of the body, with the highest concentrations occurring in connective tissues such as skin and cartilage. Hyaluronic Acid is an important constituent of joint fluid where it serves as a lubricant and plays a role in resisting compressive forces. What is Hyaluronic Acid (HA)? HA is found within collagen throughout the body. As the most important space filling substance in the human body HA holds more water than any other molecule in the body and is necessary to keep collagen hydrated and youthful. What does HA do in the body? HA supports the structure of connective tissue by acting as a water magnet. HA forms a viscous fluid with exceptional lubricating properties necessary for the vital functions of many parts of the human body including the skin, heart valves, aqueous/vitreous humor of the eye and synovial fluid (joint lubricant). The skin contains over 50% of the body's HA. Considering that skin is over 70% water and renews itself more readily than most other bodily tissues HA is absolutely vital for its structure and daily maintenance. Skin is constantly involved in renewal and repair because of daily exposure to solar radiation, pressure, heat, trauma and wound healing. How much HA should I take? Our bodies are in a continual state of rebuilding. New skin cells for example replace old ones about every 20 to 30 days. The rate of HA degradation can be increased by excess intake of riboflavin (B-2), ultraviolet radiation exposure and viruses. Any long-term overexposure to any of these may result in premature connective tissue destruction. What is the purpose of MSM in this formula? MSM is an organic source of sulfur, a mineral necessary for the normal function and structure of the body. Sulfur is a raw material utilized by the body to manufacture proteins, cartilage and other connective tissues. Studies with MSM have proven it to be safe and effective for the use of various types of connective tissue needs.
