Which Shark Is The Most Potent?

Shark liver oil and shark cartilage are both pretty impressive supplements, but which one is the most potent?  According to researchers, the liver oil may be a more potent cancer fighter.  Shark liver oil is rich in vitamins A and D and also contains the compound squalene and alkyglycerol (AKG), which seem to have a powerful strengthening effect on the immune system.  It is also a strong antioxidant and may be helpful in protecting cancer patients before, during , and after radiation treatment.
