What Is Medical-grade Sodium Hyaluronate?


Sodium hyaluronate is a natural substance found in the human body. This sodium saltis a visco-elastic long-chain polymer of sugar units of Na-glucuronate-N-acetylglucosamine. It is widely present in the extracellular matrix of connective and neural tissues in our body. Sodium hyaluronate is also involved in cell differentiation, wound healing, and inflammation.


Sodium hyaluronate plays an essential part in modulating the interactions inside our body. First, medical-grade sodium hyaluronate could form a viscoelastic solution, which serves as a protective barrier for our tissues and cells. The solution could also absorb mechanical stress. Last, this sodium salt is thought to provide nutrients to injured cells to promote tissue repair and cell growth. With these notable properties, medical-grade sodium hyaluronate is applied to treat arthritis, cataract, dry eye syndrome, and other diseases.

What Are the Medical Uses of Sodium Hyaluronate?

--Sodium Hyaluronate for Intra-articular Injection

Sodium hyaluronate is a component of the joint fluid that lies between your bones and cartilage. The fluid acts as a lubricant and absorbs shock in the joint, so you can move smoothly. Nevertheless, people with osteoarthritis have less hyaluronic acid and less joint fluid, causing pain, swelling, stiffness, and other uncomfortable symptoms. If you have thesesymptoms, you just need an injection of sodium hyaluronate torecover the viscoelasticity of the articular fluidand stimulate new fluid production.

--Sodium Hyaluronate to Cure Eye Diseases

Sodium hyaluronate is also extensively used in ophthalmic surgeries.

You can use medical-grade sodium hyaluronate to make artificial tears to alleviate dry eye syndrome. These artificial tears can form stable water film on the ocular surface to moisturize your eyes for a long time. Therefore, you can be saved from redness, itchy eyes, and blurred vision.
