GABA vs Melatonin: The Brake vs The Clock

Insomnia usually has two causes: "I can't stop thinking" (Hyperarousal) or "I'm not tired yet" (Circadian Rhythm).

GABA treats the first one by slowing down brain activity. Melatonin treats the second one by tricking your brain into thinking it is dark.

Mechanisms: Slowing vs Signaling

GABA: The Brake Pedal

GABA (Gamma-Aminobutyric Acid) is your brain's primary inhibitory chemical. It tells neurons to stop firing.

Taking GABA supplements creates a physical sensation of relaxation, often starting in the gut or muscles.

Melatonin: The Light Switch

Melatonin does not inherently "sedate" you. It creates the *drive* to sleep by signaling to the suprachiasmatic nucleus (your master clock) that the sun has gone down.

Which One Matches Your Goal?

For Stress Relief

Winner: GABA.

Melatonin does nothing for anxiety. In fact, taking Melatonin when you are stressed can just make you feel "tired and wired." GABA addresses the stress directly.

For Fixing Your Schedule

Winner: Melatonin.

If you have been staying up until 3 AM and need to wake up at 7 AM, Melatonin is the only tool that can shift your biological clock.

The Verdict

Choose GABA if: You are dealing with stress, tension, or inability to relax.

Choose Melatonin if: You are traveling or trying to fix a broken sleep schedule.
