Don't be surprised if you see Seattle Mariners sensation Ichiro Suzuki downing an Ajinomoto Co. amino acid drink in the dugout at Safeco Field during a baseball game.

The Tokyo-based firm, a major manufacturer of amino acid products, has a contract this year with the team to offer Amino Vital powder and drinks as supplements to help prevent fatigue, increase the burning of fat during exercise and assist in muscle recovery.

Such benefits are also attracting athletes of other sports as well as health-conscious consumers.
