Hyaluronic acid is a glycosaminoglycan. In osteoarthritis, changes occur in the hyaluronic acid found in cartilage leading to degradation of the cartilage. With continued use, Fulvic Enhanced™ products are able to aid the natural manufacture process of glycosaminoglycan to firm cartilage tissue. As published in WebMed “There isn’t enough information about hyaluronic acid to know if it is safe when taken by mouth”. Under joint health information by Ray Sahelian, M.D.: “Whether ingested as a pill it is able to easily enter joint tissue is not fully understood at this time. As to the injectable form, the results are mixed. At this time, I don’t have a strong opinion on the benefit of oral form of hyaluronic acid since I have not come across many studies evaluating its effectiveness for joints.”
