Claims audit / 02

What does it claim?

Each claim is rated separately. Ingredient evidence does not prove that this finished product produces the same result.

Claim 01 / Magnesium glycinate

Fixes insomnia and calms the nervous system.

Promising

Meta-analyses find small improvements in sleep onset time, mostly in older adults who were low on magnesium to begin with. Quality of trials is low.

See research

Claim 02 / L-theanine

Relaxation without drowsiness.

Promising

Short trials show reduced stress scores and better sleep quality at 200mg, but effects are modest and study lengths are weeks, not years.

See research

Claim 03 / Apigenin

Binds sleep receptors like a natural sedative.

Limited

Receptor binding is real in the lab. Human sleep trials using chamomile are few, small and inconsistent.

See research

Evidence review / 03

What does the evidence say?

Evi rates the research behind each claim. Unless an exact-product study is recorded, ingredient findings describe the ingredient—not proof that this finished formula produces the same result.

What we found

  1. 01

    Magnesium helps most if you were short on it. If your diet already covers it, the effect is likely to be small.

  2. 02

    The glycinate form is chosen because it's gentle on the stomach — not because it's magically stronger.

  3. 03

    The relaxation ingredient from green tea has decent short-term evidence for feeling less wound up at bedtime.

  4. 04

    Chamomile's active compound does touch the same brain receptors as anxiety medication, but at doses far below anything that would sedate you.

Independent summary

The Evi Take

Low risk, mild benefit. Helpful as part of a wind-down routine; not a treatment for real insomnia.

An evidence-focused interpretation—not a diagnosis or personalized medical treatment advice.
