Some researchers believe that shark liver oil derived from deep-water sharks may prove useful in fighting cancer and boosting the immune system. Today, shark liver oil is extracted from sharks that are caught off the coasts of Greenland, Norway, and a few other northern European countries.

It is important to know that shark liver oil is substantially different from shark cartilage supplements, even though both come from the same fish. Shark liver oil contains potentially therapeutic substances unlike those found in the cartilage.

Shark Liver Oil Medicinal Indications and Applications

Historically, shark liver oil has been used by the culture of northern Europe as a folk remedy for wounds and the flu. Shark liver oil contains a number of substances including alkylglycerol and squalmine, both of which are believed to possess medical properties. Much of the interest in shark liver oil stems from its alkylglycerol content which is believed to act as a potential complement to traditional cancer trainings and as an immune boosting agent. In animal studies, squalamine has been shown to fight cancers of the lung, breast brain, and skin by choking off the tumor's blood supply. Also found in high concentrations in shark liver oil are omega3 fatty acids and vitamin A.

Shark liver oil has been used in lip balms to moisturize and prevent chapping, and claims have been made that it may even help heal canker sores. However, evidence is weak supporting that shark liver oil can cure serious diseases such as AIDS, arthritis, chronic fatigue, fibromyalgia, or psoriasis.

Most meaningful studies have focused on the possible benefits of shark liver oil in fighting cancer and infections. Unfortunately, most studies to date have been inconclusive. However some researchers contend that shark liver oil shows real promise and more rigorous human studies are under way.

Dosage Information

As a complement for cancer treatments, take 1 to 2 capsules (providing 100 mg alkylglycerols) 3 times per day with meals. For fighting infections take 1 to 2 capsules a day with meals, for one week. Do not exceed manufacturer's recommended dosage.
