I stumbled across this on the Torq website about the benefits of 2:1 glucose (maltodextrin) /fructose intake. Thought I’d share - torqfitness.co.uk/news/maltodextrinfructose
It refers to a number of studies (I’m not personally going to be tracking them all down) for those who like to do further reading. Something new to me was the statement that a 90g serving would be needed to gain benefits over just maltodextrin alone. I thought the benefit was that the 2 sugars could be absorbed simultaneously (I suppose maltodextrin is absorbed pretty quickly anyway), but Torq say 60g will saturate the intenstine’s glucose transporters, so the benefit of taking in fructose comes at that moment. In other words, if you only use 60g of carbs in your drink (what I’d been doing for a few weeks), don’t bother with fructose. Maybe I missed the memo and apologies if so, but I don’t remember seeing this discussed - explains Beta Fuel coming in 88g sachets too.
“It is important to point out that in order to experience the benefits of using multiple transportable carbohydrates over that of a single form of carbohydrate you need to saturate the transporters in the intestine that absorb the carbohydrate as comprehensively as possible, so to experience the benefits, an intake of 90 grams of carbohydrate per hour is recommended. Taking on board only 60 grams per hour will supply a good level of carbohydrate to the blood with an extremely low chance of any gastrointestinal discomfort, but the higher does are where the true benefits of maltodextrin:fructose lie over single carbohydrate forms.”
