GSF-Syrup is the new name for Hypo-Fit, the name reflecting the components of this sugar source and potential hypo-halter. The fluid comprises glucose, sucrose and fructose (hence GSF) that provide a more stable way to bring yourself out of hypo. The sugars absorb at different rates, so one gets into your system really quickly, the others a bit slower – this way you come out of hypo with a reduced chance of going back into a low blood sugar. As well as the original box of 12 sachets (around £14.00 per box), there is a now a 3-sachet option (each sachet has 18gms containing 13gms of usable sugars).
