Coagulation and platelet aggregation. (A) Platelet counts and (B) Fibrinogen concentrations, in the 50 study participants, categorised by supplement use, median values indicated. There was no apparent difference in routine coagulation screens (prothrombin time, activated partial thromboplastin time, data not shown). (C) Platelet aggregation to stated concentrations of adenosine diphosphate (ADP) in the subgroup of 11 participants undergoing platelet aggregation studies, categorised by ingestion of no supplements (‘None’, N = 7), supplements other than fish oil (‘non fish’, N = 3), and fish oil (N = 1). Means and standard deviations illustrated.
