That's not a lot of energy.
How do you get "plenty of long term energy" from 3 grams of sugar and some vitamins?
The energy source is amino acids. After the body burns simple sugars, it burns fats and amino acids. I've had matches where I came in without eating for several hours. After the first few games, I thought I was finished, but as soon as the amino acids kicked in I got my second wind, and I literally felt more energetic after 2 hours than after the first 15 minutes.
