Over/for

Hello,
Could you please tell me whether we can use both 'over' and 'for'
in the sentence below :

Guarana releases its caffeine gradually causing sustained energy over/for a long period of time.

I think 'over' means the same as 'during'...

Thank you very much for your help,
Kind regards.

One nuance between the two is that I believe "over" has the added implication that the energy is released throughout the duration of time and lasts throughout that time; whereas, "for" implies that it may be released all at once, but lasts for a long duration. Since you use the words "gradually" and "sustained" I would think that "over" is a better choice for the point you are trying to make.
