The Claim

A single dose of a multi-ingredient energy supplement containing 55 mg of caffeine is associated with changes in resting state EEG patterns that reverse fatigue-related brain activity in adults.

Source: Multi-ingredient energy dietary supplement with a small amount of caffeine modulates central and autonomic nervous system after a single use.

In plain English

A single dose of an energy supplement with 55 mg of caffeine alters brainwave patterns during rest in a way that counteracts changes typically seen during mental fatigue in adults.

See the scientific wording

A single dose of a multi-ingredient energy supplement with 55 mg of caffeine is associated with changes in resting state EEG patterns that reverse fatigue-related brain activity in adults, suggesting potential modulation of central nervous system function.

Why this might work

Caffeine and other ingredients in the supplement enter the brain and block signals that make the brain feel tired. This wakes up brain regions that control alertness, which changes the brain's electrical activity to match that of a non-fatigued state.

What the research says

1 study

  1. Study: Multi-ingredient energy dietary supplement with a small amount of caffeine modulates central and autonomic nervous system after a single use.

    This study found that drinking one energy drink with 55 mg of caffeine changed brain wave patterns in tired adults, making them look more like those of alert people — suggesting it helps fight mental fatigue. The changes were real and measured scientifically.
