The authors have read the journal's policy and have the following conflicts: Funding for the trial was provided by Martek Biosciences Inc., who also provided product and placebo. PM, JRB, and RPS declare that no other competing interests exist. AJR acts as an occasional paid consultant (lectures and advisory work) for companies and organisations involved in producing, selling, or promoting foods or supplements containing ω-3. None of these issues alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
