Can anyone explain the Nutritional Information on this OGTT?

[IncogKeto]

The response you received from Galen makes sense to me - even though there was no mention of the 50.3g of sugars - but it just shows how easily I could have made a mistake if I'd mixed the solution myself. It appears to require much more knowledge than I'd imagine most people realise.

I'm now doubting my understanding of Nutritional Information Labels in general. Who would have thought that 23.8g of Carbohydrates (16.8g of sugars) would be the equivalent to 25g Glucose once ingested? Presumably a similar thing is happening with a number of food items that I'm consuming!

Oldvatr: Do you feel confident that the Rapilose is fit for purpose when performing a Tolerance test?
And do you think that the pre-made solutions would all induce a similar response in a particular person?

I am satisfied that Rapilose will perform an OGTT in line with the WHO guidelines. I am not entirely convinced that the polysaccharide syrup mixure is totally equivalent to a pure glucose hit in terms of timing, since long chain sugars which is what they are do take longer to breakdown compared to simple carbs. In effect the syrup gives a carb hit not a sugar hit. But syrup needs less refining, so is cheaper. So long as you are not trying to check your Stage 1 insulin response you won't notice the carb difference flattening the curve a little. It may be that the syrup version may give slightly different values for Insulin resistance (which is effectively Area Under the Curve) but for a home test the accuracy of the glucose meter will mask it anyway. [Note to self: using a CGM will have some extra delay so maybe shift the blood draw to something like 2hr_20 minutes]

So it was a good question, and as you say here, we all learnt something from the exercise. I hope that it will help others to do a home OGTT with more confidence. And we have other sources of readymix gloop to try. Even Lucozade could be used, but it has to be the original Sports formulation, not the new fangled version, and requires, I believe, 394ml to get the hit.
