Used widely in the NHS, each pack of GlucoBoost consists of an 80g bottle of clear glucose gel
A 25g dose contains 10g of carbohydrates each, mainly in the form of dextrose (glucose).
If you have diabetes it is always best to check your blood glucose before eating GlucoBoost to confirm that your blood glucose is low and that you need extra carbohydrates.
NICE guidelines state that when 10-20g of carbohydrates are administered, blood glucose levels should increase in 5-15 minutes.
GlucoBoost can be administered through a PEG tube, however you would not expect as quick absorption as you would through the buccal route (mouth/oral administration). It would be expected to increase blood glucose but not as quickly or as dramatically.
