Each third of a bottle of Glucogel contains approximately 10 grams of fast-acting carbohydrates, mainly in the form of dextrose (glucose). If you have diabetes it is always best to check your blood glucose before eating Glucogel 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. Glucogel 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. Glucogel has never been tested on animals. Glucogel is Gluten, Dairy, Lactose, Wheat and Fat free.
