The shark is one of the most remarkable creatures on the face of the earth. Existing virtually unchanged for 250 million years, shark's are unique in that they have a natural immunity to almost every problem known to man. When a shark is wounded, it heals quickly. The shark is the only animal with a skeleton comprised entirely of cartilage which accounts for between 6 and 8% of its body weight. Rich in mucopolysaccharides, each 750 mg capsule contains only pure Pacific shark cartilage with no additives, fillers or binders.
