Hyaluronic Acid (HA) has been known for over 70 years and is found in the skin, lymph, joint cartilage and the tissues between the organs. Fifty percent of all hyaluronic acid in the body resides in the skin. The amount of hyaluronic acid declines steadily over a lifetime, especially after 40. As we age, HA is broken down, and this digestion is thought to contribute to the disease and conditions often associated with aging, such as arthritis and wrinkling. HA Extreme supports good health by replenishing healthy levels of HA lost with age. For the last thirty years, hyaluronic acid has been injected directly into the joints to relieve joint pain and now HA Extreme provides joint relief in a topical form. HA Extreme is a patented combination of menthol with hyaluronic acid, scientifically formulated to give fast, long lasting pain relief. Aching muscles and sore joints are a part of everyday life, and HA Extreme has been formulated with this in mind. Other pain relievers use three basic mechanisms to create the illusion of pain relief. Some contain high concentrations of essential oils, such as eucalyptus or methyl salicylate that create local inflammation and warm the skin. Others contain menthol and alcohol that evaporate quickly, numbing the skin and giving the "feeling" of pain relief - often leaving the skin dry and irritated. Still others, like capsaicin, are thought to actually deaden the nerve endings - these usually take several weeks of regular application in order to show pain relief. HA Extreme uses menthol for fast relief and high molecular weight hyaluronic acid for long term joint and muscle health. Regularly using HA Extreme aids in the replenishment of hyaluronic acid in the body, which can help protect against the breakdown of cartilage and aid in restoration of joint fluids.
