Can hyaluronic acid be eaten?

When it comes to hyaluronic acid, many people think of cosmetics, and many beauty and skin care products contain hyaluronic acid. Recently, however, a series of foods containing hyaluronic acid have appeared on the market, such as hyaluronic acid bubble water, hyaluronic acid soft candy, hyaluronic acid jelly and hyaluronic acid milkshake. Hyaluronic acid has been transferred from cosmetics industry to food industry. Can you really eat it?

Hyaluronic acid, also known as hyaluronic acid, is an acidic mucopolysaccharide existing in human body, which widely exists in joint cavity, skin and other tissues of human body. Hyaluronic acid has a strong water absorption ability, which can help the skin lock in moisture, thus playing a role in moisturizing; In addition, hyaluronic acid has the functions of lubrication, promoting fracture healing and antioxidation.

Hyaluronic acid added to food generally exists in the form of sodium salt, namely sodium hyaluronate. At present, sodium hyaluronate has been approved as a new food raw material in China, which can be used in milk and dairy products, beverages, alcohol, cocoa products, chocolate and chocolate products, candy and frozen drinks. The recommended intake is ≤ 200mg/day. From this point of view, hyaluronic acid can indeed be eaten, but can oral hyaluronic acid make the skin better?

In fact, oral hyaluronic acid can not directly affect our skin. Hyaluronic acid, like starch, is a macromolecular polysaccharide and cannot be directly absorbed and utilized by human body. It needs to be digested by the gastrointestinal tract and decomposed into small molecular substances before it can be absorbed and utilized by the human body.

This part absorbed by the human body may be converted into energy to provide energy for the human body, or some macromolecular substances may be synthesized, which may not necessarily appear stably in the face or skin. Therefore, in the face of these various hyaluronic acid products, everyone should keep a clear head and plant grass rationally.
