In addition to its large liver and high oil content, it is rich in vitamins A and D and is the raw material for the extraction of cod liver oil.
The small peptides extracted from squid using modern biotechnology and enzyme engineering techniques are rich in soluble calcium and have extremely high bio-safety and are easily absorbed by the body.
