The GI will have an impact on the speed also - coke is 63 on the GI index whereas Glucojuice is pretty much the gold standard in speed at 103. 15g of pure glucose in a bottle.
I have jelly babies during the day, but on my bedside table for the middle of the night I have those 150ml cans coke. I find the C02 makes it work quicker. Important for me when I’m half asleep.
I think it all comes down to personal preference and how many carbs you need to treat your hypo.
I prefer to use either Dextro energy tabs for carrying around, or pure Dextrose Monohydrate dissolved in water when at home.
I have always taken lucozade as my favourite and "works for me" Hypo stopper.. It works quickly (two or three large gulps) and 15 minutes later I am feeling on the mend.
Totally down to what you find better. When Hypo my only concern is to stop it as quickly as possible without having to go through any analysis regarding grams of sugars and carbohydrates..
