Straightliner: It’s very unlikely to be the Maltodextrin. Torq gels contain Fructose, however, which does give some people GI issues. Maltodextrin is amazing stuff: Cheap, gives sustained energy, Very low osmolality and dissolves at very high concentrations. It doesn’t cause tooth decay either.
Has anyone done a study on the 2:1 (Malto: Fructose) formula at high intensity yet? As far as I know all these “2:1” products (in theory, the benefit is faster absorbtion than pure malto) are based on Jeukandrop’s study, which was done at relatively low intensities. At low intensities you can pretty much eat anything…stomachs generally get more particular the harder you go (and the hotter it is)
I find Torq gels are the tastiest but my fussy stomach gets on best with the isotonic orange SIS ones – I use maltodextrin in my drink as well, so it wouldn’t work so well with non isotonic gels either.
SIS drink contains Aspartime (gives many people nausea, including me) it’s not in the gels though
