just looking at the nutrition label you kindly provided -- it has less than half the carb content per 100 grams in comparison to lucozade
lucozade is glucose in the first instance which is what the body requires when hypo.
i saw the label of the gel contained fructose -- which is also a sugar but perhaps not quite as efficient,
perhaps give it a go next time you have a hypo and see how you get on with it.
