Bayer Healthcare's Arctic Wonder Market Test Succeeds With Neptune Krill Oil Leading to U.S. National Launch

Neptune Technologies & Bioressources Inc. ("Neptune") (Nasdaq:NEPT) (TSX-V:NTB) is pleased to announce that Bayer Healthcare, LLC Consumer Care Division has formally launched its Arctic Wonder proprietary Neptune Krill Oil ("NKO") in the United States in March 2011 after a successful market test.

Bayer's market test conducted over the last year with NKO® under its Arctic Wonder brand was performed in the U.S. internet direct response e-commerce channel of trade.

"Acasti management team is delighted by the relationship Neptune has developed with Bayer. This is yet another significant milestone for Neptune's strategic planning which will help NKO® achieve extensive consumer awareness and appreciation. We are looking forward to a successful long-term collaboration with Bayer," stated Dr. Tina Sampalis, President of Acasti Pharma.

"The agreement with Bayer, the market test results and the marketing approach for Arctic Wonder NKO® not only create broad consumer awareness, confidence and appreciation but also distinguish NKO® as the superior and prime choice amongst competitor krill oil products," said Mr. Henri Harland, President and CEO of Neptune. "Arctic Wonder is entering the rapidly growing omega-3 market which has shown a sustained annual growth of 12% according to the Frost and Sullivan Report 2010. The omega-3 category is valued at $1.7 billion and expected to reach $3.5 billion in 2015. We believe the full launch by Bayer of Arctic Wonder will achieve immediate success which will in turn positively influence our growth and increase Neptune's krill oil market share, reinforcing Neptune's position as the industry leader and Neptune Krill Oil as the gold standard of quality and efficacy for krill oil products in the market," he added.
