Shark oil, traditionally derived from the livers of deep-sea sharks, has been used for centuries in coastal cultures for its perceived health-supporting properties. Historically, Scandinavian and Japanese fishing communities valued shark liver oil as a folk remedy to promote resilience during harsh winters, support immune function, and enhance overall vitality. Today, it is available in capsule and liquid formats, continuing its legacy as a marine-based supplement rooted in traditional use while adapted for contemporary wellness practices.
Key Shark Oil Health Benefits
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 prevent chapped skin and wrinkles. The alkylglycerols in this oil have been studied for their possible benefits against unhealthy cell growth and infections.
In Europe, this oil is widely used to support healthy cell turnover because the alkylglycerols in shark liver oil may prime the immune system, causing unhealthy 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. This 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.
Shark Oil Supplements
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.
Cautions & Considerations
Mild digestive upset, including nausea, diarrhea, and indigestion, may occur, especially when you first start taking shark liver oil.
