Squalene is a hydrocarbon and a triterpene, and is a natural and vital part of the synthesis of all plant and animal sterols, including cholesterol, steroid hormones, and vitamin D in the human body.Squalene is used in cosmetics, and more recently as an immunologic adjuvant in vaccines.Squalene has been proposed to be an important part of the Mediterranean diet as it may be a chemopreventive substance that protects people from cancer.qualene is a low density compound often stored in the bodies of cartilaginous fish such as sharks, which lack a swim bladder and must therefore reduce their body density with fats and oils.
Many ancient Mediterranean cultures believed that olive oil increases strength and longevity, and indeed the olive tree is a rich source of squalene. Extra-virgin olive oil contains about 200 - 450 mg squalene per 100 g oil. 4 In India, the amaranth herb has been widely used for thousands of years.his oversized liver contains between 50% and 70% squalene. Squalene is a source of energy for the sharks and allows them to live at these depths and thrive in an environment that is harsh and oxygen-poor.
