Maltodextrin is an oligosaccharide.

I disagree with the terms simple or complex, it's mostly an irrelevant use of words whereas we should should focus on the insulin index or a Glycaemic load index.

In any event, it's processed insulin spiking shite!

MAKE YOUR OWN GAINER WITH WHEY AND POWDERED OATS AND MAYBE SOME NATTY PB.

Or maybe eat some real food.
