Evidence Lens
Midlife health advice can be overwhelming. Evidence Lens helps women ages 40-65 make sense of supplements, habits, and wellness options by showing what clinical trials and research publications actually say.
Try asking
What you’ll get
Clear signals from human studies — without hype.
Does magnesium help with sleep?
Same study card layout as after you search — illustrative seed, not your query.
Key Takeaway
Elderly participants taking 500mg magnesium daily for 8 weeks showed improved sleep quality scores and reduced sleep onset time compared to placebo.
Why this looks relevant
Structured score: 10/10
- Population is a direct match for people asking this question.
- Intervention directly tests the health practice in the query.
- Outcome directly measures the target benefit users care about.
- Published human results are available.
Why confidence is moderate
Structured score: 4/7
- Randomized controlled design supports stronger causal inference than observational data.
- Small sample size limits how much confidence to place in the finding.
- Published human results are available.
- Outcome uses a mix of objective and subjective measures.
- Small sample size reduces certainty.
- Single-center design may limit generalizability.
- Short follow-up limits confidence about durability of the effect.
