Israeli biotech company Enzymotec is going head to head with market leader Neptune Technologies by moving into the krill oil market. Enzymotec, which makes lipid-based ingredients targeting heart, brain and infant health markets, said its krill oil could give "additional benefits to customers by providing higher levels of phospholipids and omega-3, conjugated on phospholipids, lower cost and not forcing limitation of customer use". High in omega-3, phospholipids and antioxidants, krill oil is derived from the planktonic family of crustaceans.
