Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be randomly allocated to one of six treatment groups using simple block randomization. Groups will be coded numerically and the allocation code concealed from the research team in sealed envelopes for the duration of the trail.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Given the multiple treatment arms in this trial, simple block randomisation will be used for subject allocation. This involves ordering the six treatment groups in a series of randomly sequenced repeating blocks. Consecutively recruited participants are then allocated to a group based on the sequence of the current block.
Masking / blinding

Summary
Brief summary
Growing research into the effects of several whey-derived proteins (cow’s milk proteins) suggests that bovine lactoferrin and immunonglobulins may have a number of health benefits for consumers including improved metabolic and immune regulation. This study aims to examine any link between bovine lactoferrin and immunoglobulin consumption and gene expression patterns which may reveal which biological pathways are involved in driving responses to these supplements.
