… and it’s used for sore throats etc so that type will obviously be ‘consumption grade’
As for the type of carbohydrate drink, I’ll admit here to not being the worlds foremost expert on ‘the bloat’ but due to the amount consumed any that you tolerate well and like the taste of would be best. I know people who have had good results on just plain sports drinks.
Obviously as far as blood sugar levels and hydration go some combination of palatinose and rice oligodext would be a nice inclusion somewhere. The latter you can’t get easily in my country - so you see how your choices may be dictated. Perhaps there is some advice on Dave Tate’s site?
How would you use it differently? Well in terms of just pre-comp then the clear difference is carbohydrate AND water (for PL’ers) and not carbohydrate without much water (BB’ers).
Obviously it goes without saying that how you tailor it depend upon many things such as making weight etc.
