Squalene is a liver oil (natural unsaturated hydrocarbon) that supports the strong vitality of deep-sea sharks that live 1000 meters deep. Originally, it is biosynthesized in a small amount in the human body and is used as a raw material for vitamin D, cell membranes, hormones, and good cholesterol. It is said to be a jade in traditional Chinese medicine and has been widely used for a long time. Nyurudo's squalene contains 99mg of high-purity squalene, 300mg per tablet.
