Claim 01 / Magnesium glycinate
Fixes insomnia and calms the nervous system.
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.

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.
Promising
Claim 02 / L-theanine
Relaxation without drowsiness.
Short trials show reduced stress scores and better sleep quality at 200mg, but effects are modest and study lengths are weeks, not years.
See researchClaim 03 / Apigenin
Binds sleep receptors like a natural sedative.
Receptor binding is real in the lab. Human sleep trials using chamomile are few, small and inconsistent.
See researchEvidence 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
- 01
Magnesium helps most if you were short on it. If your diet already covers it, the effect is likely to be small.
- 02
The glycinate form is chosen because it's gentle on the stomach — not because it's magically stronger.
- 03
The relaxation ingredient from green tea has decent short-term evidence for feeling less wound up at bedtime.
- 04
Chamomile's active compound does touch the same brain receptors as anxiety medication, but at doses far below anything that would sedate you.

- Quantity
- 6 unique sourcesCounted once per source, however many claims cite it.
- Directness
- Ingredient-level evidenceExact-product studies count above ingredient or category research.
- Replication
- More than one human studyOne study alone cannot support a Strong level.
- Relevance to claims
- 3 of 3 claims have matched researchOnly research matched to a specific claim is counted.
- Finished product vs ingredient
- Ingredient only — not proof for this formulaIngredient research never establishes that this formulation works.
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.
