We can't stop the 24-hour news cycle. But we can help you sleep through it.

Gaily Slumber is a clinician-formulated sleep support supplement built for those of us whose nervous systems don't automatically clock out at bedtime. It works on multiple levels to ease you into sleep, hold you there, and let you greet the next day like you actually slept. 

Slumber is a five-ingredient formula built to bring you down without knocking you out.

  • GABA has been shown in human research to promote relaxation and ease anxiety within about an hour of intake.1
  • L-theanine, across a 2025 meta-analysis of 19 clinical trials, significantly improved sleep onset, daytime function, and overall sleep quality2, and some animal research suggests it teams up with GABA for deeper, more restorative sleep.6
  • Magnesium bisglycinate works on two fronts, the mineral and the calming glycine it's bound to, with a 2025 clinical trial showing this exact form improves sleep quality in adults with poor sleep.3
  • Vitamin B6, in its bioactive P-5-P form, is an essential cofactor your body needs to make its own GABA and serotonin.4
  • And the melatonin dose is 1mg on purpose: low doses support your sleep-wake cycle without the grogginess or vivid dreams that come with higher-dose formulas.5 Because waking up groggy isn't rest, it's just a different kind of tired.
HOW TO USE

Take 2 capsules 30 to 60 minutes before bed. Some people find 1 capsule is enough. Your body will tell you. Consistent nightly use supports cumulative benefits.

Melatonin, GABA (gamma-aminobutyric acid), L-Theanine, Magnesium (as bisglycinate chelate), Vitamin B6 (as pyridoxal 5'-phosphate)

BENEFITS

  • Fall asleep faster, actually

    GABA promotes relaxation within about an hour of taking it1, and L-theanine has been shown to improve sleep onset time.2

  • Sleep that goes deeper

    L-theanine's 2025 meta-analysis found improvements in overall sleep quality, not just falling asleep2, and magnesium bisglycinate has shown benefits for adults with poor sleep in its own right.3 Getting there matters. Staying there is the work.

  • Wake up like a person

    Low-dose melatonin supports your natural sleep-wake cycle without the morning grogginess or vivid dreams that come with high-dose formulas.5

  • Your nervous system,
    winding down on purpose

    Magnesium supports healthy nervous system function, B6 helps your body produce its own calming neurotransmitters4, and GABA adds a direct relaxation effect on top1, for a genuine wind-down rather than a chemical override.

KEY INGREDIENTS

  • Melatonin

    We chose the lowest clinically effective dose. Low-dose melatonin (0.1 to 0.3mg) has been shown to support the body's natural sleep-wake cycle and sleep onset without the heaviness or vivid dreams associated with higher-dose formulas.5 Chosen specifically because your morning matters too.

  • GABA

    Human research found that GABA intake significantly increased relaxation-linked brain wave activity and supported immune resilience under acute stress within about an hour.1 Some animal research also suggests a link between GABA and L-theanine when taken together for deeper sleep.6

  • L-Theanine

    Promotes relaxation without drowsiness by supporting alpha brain wave activity. A 2025 meta-analysis of almost 900 people found L-theanine significantly improved sleep onset, daytime function, and overall sleep quality.2

  • Magnesium (as bisglycinate chelate)

    Supports healthy nervous system function, and the glycine chelate component is thought to contribute complementary calming properties.3

Gaily Slumber FAQ

  • Slumber is a five-ingredient formula (GABA, L-theanine, magnesium bisglycinate chelate, vitamin B6, and a low 1 mg dose of melatonin) built to ease you into sleep, keep you there, and let you wake up like an actual person.

  • 1 mg was a deliberate choice. Low-dose melatonin supports your natural sleep-wake cycle without the grogginess or vivid dreams that come with the higher doses (5, 10mg) common in other sleep products.

  • That's the exact problem it's designed to avoid. Between the low-dose melatonin and the GABA/L-theanine combination working on sleep quality rather than sedation, most people wake up clear rather than foggy. Individual response varies, as always.

  • Take 2 capsules 30 to 60 minutes before bed. Some people find 1 capsule is enough; your body will tell you. Consistent nightly use supports the cumulative benefits.
