Shark Oil
Updated Jun. 07th, 2023
Shark liver oil is a supplement that contains alkylglycerols, squalamine and squalene. It has been added to lip balm and cosmetic products because squalene moisturizes and prevents chapped skin and wrinkles. The alkylglycerols in shark liver oil have been studied for their possible benefits against cancer and infections.
In Europe, shark liver oil is widely used to complement traditional cancer treatments because the alkylglycerols in shark liver oil may prime the immune system, causing cancer cells to come under attack and preventing spread of disease. The oil may also fortify healthy cells and ease the harsh side effects of cancer chemotherapy and radiation treatments. Shark liver oil has been used traditionally to protect against, as well as speed the healing of, colds, flu, and various minor skin infections. It may also be helpful for asthma, arthritis, and the skin inflammations of psoriasis because of its anti-inflammatory properties.
Supplements are obtained from sharks caught off of Greenland, Norway, Sweden, and other coasts. The oil is available as a by-product of the commercial fishing industry; endangered sharks are not allowed to be killed solely for their oil. Some supplements are standardized to their alkylgylcerol content as a guarantee of their quality. It is important that supplement makers test and process the oil properly to remove potential toxins such as PCBs and mercury. Keep capsules away from heat because they can become rancid.
Mild digestive upset, including nausea, diarrhea, and indigestion, may occur, especially when you first start taking shark liver oil.
