Less than 15 years ago a compound discovered in a particular fish liver oil was identified as providing an immune system boost. The physicians who researched this compound were seeking a way to boost their patients immune system against a particular cancer. The compounds that were identified as building immune system against the cancer were identified as alkylglycerols. These alkylglycerols were obtained from the livers of coldwater sharks such as the Greenland shark. The fact that cancer is very rare in sharks may be due to the presence of alkylglycerols in their livers. The researchers found that the biologic effects of shark liver oil include stimulation of blood leukocyte and thrombocyte production as well as the activation of macrophage and anti-tumor activity.
Put another way, alkylglycerols led to lowered cancer cell reproduction and a reduced ability of the cancer cells to invade healthy cells. The authors concluded that alkylglycerols possess both cancer preventative properties, as well as cancer treatment effects. Alkylglycerols are beneficial against other enemies of our health, because they are known to increase the production of certain cytokines that attack viruses. According to some researchers, viral infections such as influenza or the common cold, can be prevented or reduced significantly by the addition of shark liver oil, taken at the first sign of symptoms. This is very good news for seniors who are concerned about fostering their senior health with an immune system boost.
