Food grade sodium hyaluronate possesses excellent hydrophilic and water-retention capabilities. When taken orally, it helps increase skin hydration, improving dryness, roughness, and fine lines, leaving skin soft, smooth, and elastic. It is often used as a core moisturizing ingredient in beauty supplements and oral beauty foods.

Sodium hyaluronate is an important component of synovial fluid, maintaining the lubrication and elasticity of articular cartilage. Oral supplementation helps support joint flexibility and comfort, making it suitable for middle-aged and elderly individuals, athletes, and those with high joint stress.

Sodium hyaluronate also plays a moisturizing role in eye tissues, helping to maintain tear stability and corneal surface moisture. Oral supplementation can provide some moisturizing support for people who use their eyes extensively or spend long hours using computers or electronic devices.

Sodium hyaluronate's excellent moisture retention helps maintain a moist environment in the oral cavity and upper respiratory tract mucosa, relieving discomfort caused by dryness. It is suitable for use in health lozenges and throat lozenges.
