Dietary interventions for perinatal depression and anxiety: a systematic review and meta-analysis of randomized…
In the population where this was tested properly against placebo, magnesium and similar minerals didn't beat placebo — does that change what you'd suggest for me?
Reasonable evidence with real limitations. how we score evidence
Caveat on this rating: The mineral analysis pooled iron, zinc, and magnesium together rather than testing magnesium alone, and the population was perinatal, so this is a null result in a specific setting rather than a definitive negative for magnesium in depression generally. The wide confidence interval reflects few trials.
Oral magnesium sold for mood, anxiety, or sleep is a dietary supplement under the Dietary Supplement Health and Education Act of 1994 (DSHEA).
Across 36 randomized trials of dietary interventions for depression and anxiety in pregnancy and after birth, 28 of them pooled, elemental minerals including magnesium were not superior to placebo for perinatal depression (standardized mean difference -0.42, 95% CI -1.05 to 0.21 — a confidence interval that crosses zero). Omega-3 fatty acids also failed; only vitamin D produced a small-to-medium benefit in postpartum depression.
Worth asking
In the population where this was tested properly against placebo, magnesium and similar minerals didn't beat placebo — does that change what you'd suggest for me?

Questions
How strong is the evidence behind this?
Resolv rates this source "moderate evidence". Reasonable evidence with real limitations. It scores 69 out of 100 on our published rubric. One caveat travels with that badge: The mineral analysis pooled iron, zinc, and magnesium together rather than testing magnesium alone, and the population was perinatal, so this is a null result in a specific setting rather than a definitive negative for magnesium in depression generally. The wide confidence interval reflects few trials. The score is calculated from recorded facts about the source — study design, funding, publication venue, sample size, preregistration — not typed in by an editor.
What is the source for this?
Dietary interventions for perinatal depression and anxiety: a systematic review and meta-analysis of randomized controlled trials. — Tsai Z, Shah N, Tahir U, et al. (2023). Published in: Reputable peer-reviewed journal. DOI: 10.1016/j.ajcnut.2023.03.025. The full source is linked on this page so you can read it yourself.
Who paid for this research, and does that matter?
Study design: Meta-analysis of randomised trials. Funding: Funding not disclosed. Independence from the proponent is not recorded. Industry sponsorship is one of the most reliably measured biases in medicine, which is why funding carries real weight in the score rather than sitting in a footnote.
Is magnesium, magnesium glycinate, magnesium citrate, magnesium oxide, magnesium chloride, magnesium aspartate, magnesium l-threonate, magtein, epsom salts FDA approved for this use?
No. Its current status is: Not FDA-evaluated for this use. Oral magnesium sold for mood, anxiety, or sleep is a dietary supplement under the Dietary Supplement Health and Education Act of 1994 (DSHEA).
