Hyaluronic Acid by Optima Naturals is a food supplement in tablets based on hyaluronic acid with copper and vitamin C. Hyaluronic Acid, thanks to its high polarity and hydrophilicity, attracts and retains water in the connective tissue, adequately supporting the levels of hydration, while protecting it from the penetration of viruses and bacteria, thanks to the possibility of organizing itself in a dense network with a protective and regulatory function. By soaking in water it takes on the appearance of a gel with different viscosity based on its three-dimensional characteristics and associating with other proteoglycans, it defines the formation of complex retinal structures known as proteoglycan aggregates, useful for the trophic and protective structural action. All of the above functions are particularly valuable for the skin and tendon structures. Copper is an essential trace element for health and life. Our body contains less than a gram but it is needed to perform some main functions. Essential for the skin, for the synthesis, the production of collagen and the formation of melanin, copper is an antioxidant mineral that protects us from free radicals. Vitamin C performs important functions in counteracting the effects of aging, moreover it also intervenes at another level: skin relaxation. Indeed, it plays a key role in maintaining the optimal density of collagen in the dermis: biochemical studies have shown that it acts as a co-factor for lysine and proline hydroxylase, two enzymes essential in the biosynthesis of collagen. It is recommended to take before meals with a little water or other drink. Do not exceed the indicated daily dose. Keep out of the reach of children under three years old. Food supplements are not intended as a substitute for a varied, balanced diet and a healthy lifestyle.
