which is best for low sugar content- as a diabetic, I'm gonna be limited, aren't I?
There's 2 entirely different products being recommended:
- carb drinks, which you'll probably want to avoid (although talk to Matt Hart at Torq fitness, he's very knowledgable), such as Torq, High 5 Source (referred to as 'High 5' here), 4:1, SIS, Go, Accelerade, Cytomax etc etc
- electrolyte tablets such as Zym, Nuun, High 5 Zero and Elete.
The former will give you energy, and do little for cramp etc IME. The latter contain nothing but electrolytes, they're more palatable by and large, certainly in large quantities, won't ruin your guts, but don't actually provide any energy, so you'll need to get it from an alternative source such as bars or gels.
Depends what the issue is: running out of energy, carb drink. Getting cramp/dehydration: electrolyte tablets.
Many of the carb drinks do claim to contain enough electrolytes to stop cramp, but many years of experimentation whilst racing has taught me that personally, they do nothing!
