The efficacy and function of fish bladder is to delay aging.

Fish bladder contains biological small molecule collagen protein, which is the raw material for human body to supplement the synthesized protein. And it is easy to be absorbed and utilized. It is stored in the form of aqueous solution in human tissues, thus improving tissue nutrition and accelerating metabolism.

It has been proved that collagen-rich foods can affect the physiological functions of certain specific tissues through the collagen-binding water, thereby promoting growth and development and enhancing resistance to disease, and play a role in slowing down the aging process and preventing the effectiveness of cancer.

Extended information:

Most scleractinian fishes have a swim bladder, an elongated, thin sac located dorsal to the body cavity, which is generally divided into two chambers and contains oxygen, nitrogen, and The swim bladder is usually divided into two chambers containing oxygen, nitrogen and carbon dioxide. The swim bladder is connected to the esophagus by a swim bladder tube called the laryngeal swim bladder, which belongs to the swim bladder of lower bony fishes, such as the carp. A swim bladder without a tube is called a closed swim bladder and is found in higher bony fish such as bass.

Functionally, except for a few fish, the swim bladder has a respiratory function, for most fish, the swim bladder is a body specific gravity regulation organ, by the swim bladder gas changes to help regulate the body's floating and sinking.
