Decision two – When you give Supplements

Choose a pre-shift supplement to stabilise the workers blood glucose levels before their shift, for safety, cost and health. Choose a Low GI mid-shift supplement at 3/4 hourly intervals, depending on the length of the shift.

Choose the pre-shift and mid-shift supplements carefully, using the following criteria

  • The pre-shift supplement needs to be almost a meal replacer that provides a Low GI product in powder form to be mixed with cold water, to encourage fluid consumption.
  • Containing high levels of protein, which is mainly missing from the workers regular diet because of cost, but which is essential to the stabilization of blood glucose pre-shift, and which provides stamina to perform the work load. 
  • Containing electrolytes to hydrate the worker and combat heat stress, and to comply with legislation which specifies a minimum of 2 liters of potable water be available to the worker every day on the job, the supplement provided should be mixed with cold water.
  • Containing the correct levels of vitamins and minerals essential to the promotion of good body functions. Including high levels of Vitamin C [250mg daily as specified by SIMRAC the Chamber of Mines research unit]. 
  • Good fats 
  • Fibre 
  • Taste 
  • Reduced hunger
  • Packaging must be easy to use
  • No ingredients that are not medically and dietetically proven
  • Safe to use

The mid-shift supplements at 3 to 4 hourly interval’s also need to be in a drink format [powder to be mixed with cold water], and should contain;

  • Low GI ingredients for a sustained energy release over 4 to 5 hours, and a stabilized blood glucose level.
  • Electrolytes to maintain hydration of the worker
  • A variety of great tasting flavours to encourage consumption and prevent product fatigue
  • Fibre to give continuity to a feeling of fullness that controls hunger pangs, and reduces intake of skaf tins High GI products.
  • No ingredients that are not medically and dietetically proven
