#randomized controlled trials

Conceptual metaphor in a bold color field palette: a single brass balance scale sits dead center on a saturated mustard-yellow seamless backdrop, photographed at eye level with a 85mm lens and shallow depth of field. One pan holds a small mound of coarse white magnesium salt crystals, the other pan holds a rumpled, empty pillow-soft wad of grey linen, and the beam hangs almost level but wavering, suggesting uncertainty. A thin electric green thread loops from the beam's pivot as a subtle accent. Soft, large-source studio light from camera left casts a gentle, defined shadow to the right across the yellow surface. Crisp metal reflections, visible salt crystal facets. Mood: skeptical, calm, quietly questioning, clean and editorial.

镁补充剂真的能助眠吗？12项试验显示宣传远超证据

镁常被宣传为天然的助眠利器，但系统综述对12项成人随机对照试验的分析表明，证据不足以将其视为常规失眠治疗。不同问卷、脑电、活动记录仪及可穿戴设备的结果差异很大，证据可信度仅为低到极低。作者采用叙述性综述而非荟萃分析，因为试验在剂型、剂量和受试者上差异悬殊。部分摄入不足的成年人可能会感到主观上稍有改善，但整体来看，尚缺乏可靠数据支持镁系统性改善睡眠。
