Chief executive Mark LeDoux said: “It remains clear that as more and more regulatory actions and warning letters are being initiated by the FDA against companies not compliant with the basic tenets of the federal laws governing manufacturing of dietary supplements, NAI is in an enviable position to expand its domestic and international client relationships.”
With the Olympic Games approaching, NAI is also predicting growing interest in its patented beta-alanine sports nutrition ingredient CarnoSyn, which is claimed to decrease fatigue in athletes, he added.
“We received yet another patent on the use of beta-alanine on March 6, 2012 and continue to receive positive feedback from around the globe."
NAI develops and manufactures customized nutritional supplements for a wide range of clients.
