from what ive learned from this board...
these two forms of gluclose r best after weight training because they 'refuel' or replenish ure muscles the best out of any carb. fruit is not as good because it replenishes ure liver stores, which is good in terms of being healthy, but not interms of muscle replenishment.
however they should be taking in conjunction with a high protein liquid for full benefit.
i personally do not take them...though have just started taking a recovery drink straight after w/outs. It is high in carbs and most of it is sugar..this will go straight to my torn muscles, giving my muscles the fuel it needs.
please correct me if i am wrong...but thats my 2c
