鎂 Magnesium × 焦慮
Magnesium for anxiety shows a coherent but weak positive signal across sources, falling clearly in Tier C (promising but unestablished) rather than B (established with caveats) or D (insufficient/disproven).
Magnesium for anxiety shows a coherent but weak positive signal across sources, falling clearly in Tier C (promising but unestablished) rather than B (established with caveats) or D (insufficient/disproven). Five converging lines of evidence: (1) NIH ODS L5a maintains an evidence map of 4 conditions for magnesium — hypertension, T2D, osteoporosis, migraine — and anxiety is conspicuously absent, indicating ODS does not yet consider the evidence base mature enough to formally assess. (2) Major psychiatric societies (APA, ADAA) have issued no public position (L5e not_addressed), which for a widely-used supplement is itself informative — they have not endorsed it. (3) All three hospital-grade consumer sources hedge consistently: Mayo 'might help ... human studies have not proven' (cautious), Cleveland 'some evidence' (neutral, single-MD attribution), Harvard 'more limited evidence' (cautious). None recommend it as a treatment. (4) Regulatory layers (FDA GRAS, EFSA AI, FDA 2022 QHC for hypertension) only cover magnesium as an essential nutrient — no anxiety-specific claim is approved anywhere. (5) Independent PubMed corroboration confirms recent (2024) systematic reviews conclude evidence is 'suggestive of a beneficial effect ... but quality of existing evidence is poor', with effects most apparent in deficient/subgroup populations. The signal is real but neither strong nor general enough for Tier B; conversely, it is not absent or contradicted, so not Tier D. Tier C is the principled placement.
評分透明度
所有分數由 7 層證據引擎計算，過程公開可查▸查看完整決策路徑（audit trail）
- compute_raw_score — 加權公式: L2×0.30 + L3×0.25 + L5×0.25 + L11×0.10 + L1×0.10 = 0.6
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高品質 SR/MA 顯示 positive (1 篇 > 0 negative)
- tier_strict_requirement_check — Tier 條件達標，未降階
- detect_disputes — 偵測到 0 個 hard + 0 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
