Hi
The only thing that really affects fitness is your level of exercise.
A.C.T. is a drink designed to provide long lasting energy, ie no "high" or "crash and burn".
I noticed you also had a question elsewhere regarding the sugar levels. As you are obviously concerned with such issues, the best thing you can do is order a free sample of A.C.T., copy and print all you can on the ingredients and take both to your Doctor. Everyone is an individual and hence what is suitable will vary.
