In order to maintain blinding, these dietitians then gave the prepared cups to two different supervisors who in turn gave the product to each participant for consumption (once-daily doses). The preparation and delivery of the product was carried out during two work shifts (morning and afternoon), depending on each participants work schedule. The supervisors recorded product administration and consumption for each participant on a control form.
