Outcomes
Primary outcome [1] 3035 0
Ex vivo changes in serum oxygen radical absorbance capacity.
Timepoint [1] 3035 0
Measured over an 8 week period at baseline (week -2) week 0, week 1, week 3 and week 5.
Secondary outcome [1] 5089 0
In vivo changes in lymphocyte subsets, lymphocyte activation, Phagocytosis of Granulocytes and Monocytes, and Cyclo oxygenase (COX 2) (anti inflammatory) activity. Participants had blood samples taken at weeks -2, 0, 1, 3 and 5 to measure these outcomes.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A third party who is independant of the trial generated the random numbers by a computer software generated sequence program. The numbers were suplied to the person who decided if the participant was eligble for the study by sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
