Quick answer

Plain creatine has no meaningful calories, but some people still keep supplements outside the fasting window for simplicity.

Step by step

01 Look up the calories and ingredients for creatine in water.
02 Choose a rule before the fast starts so you are not deciding while hungry.
03 Use the same rule for at least a few fasts before judging whether it works.

The longer answer

Plain creatine has no meaningful calories, but some people still keep supplements outside the fasting window for simplicity. In everyday intermittent fasting, the easiest rule is to keep the fasting window to water, plain tea, and black coffee unless you intentionally follow a modified fast. Track the choice so you can see whether it affects cravings or consistency.

Tip

If creatine in water makes you hungrier, switch back to water, plain tea, or black coffee for a cleaner test.

Common mistake

Changing the rule for creatine in water every day and then not knowing what actually helped.
