The effect of magnesium supplementation on primary insomnia in elderly: A double-blind placebo-controlled clinical trial

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.
