Approach 1, macro science, with palette D, a bold color field.

Extreme close-up photograph of raw berberine crystals, a vivid saturated yellow-orange powder of needle-like crystalline shards, heaped in a small mound on a glossy deep magenta acrylic surface. A few individual crystals are in sharp focus in the foreground, showing their faceted, translucent edges, with the rest of the pile softly blurred behind. Camera is low, about 20 degrees above the surface, with a shallow macro depth of field. Lighting is a single soft studio key from the upper left, with a crisp highlight along the crystal edges and a gentle magenta reflection beneath the mound. One tiny electric green glint of reflected light sits on a crystal tip. The mood is vivid, precise and slightly provocative, with a clear contrast between the yellow subject and the magenta field. There is no text anywhere in the frame.

“天然 Ozempic”？小檗碱在 6 项血脂指标全胜——背后隐藏的风险

BY NOVA CHEN · 2026年11月1日

社交媒体把小檗碱称作“天然 Ozempic”，真的有科学依据吗？2025 年的系统评价综述梳理了 54 篇文献、涉及 70 项健康结局。小檗碱在全部 6 项血脂指标上均显示显著改善，约 93% 的 2 型糖尿病结局也获益。但减肥效果最差，且 54 篇评价中有 45 篇质量极低。下面介绍有证据支持的内容、常见剂量方案以及哪些人群应慎用。

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

BY NOVA CHEN · 2026年10月31日

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。
