Macro science close-up of spirulina itself: a dense mound of dried spirulina filaments and flakes, shot from a low three-quarter angle with a macro lens and a shallow depth of field. Crisp, deep blue-green coils and fine threads sit in the focal plane, and the rest melts into soft blur. One small pile rests on a smooth, glossy tomato-red ceramic surface, and the saturated red field contrasts hard with the green algae. Lighting is bright, diffuse studio daylight from the upper left, with soft highlights on the powdery grains and gentle warm shadows. A single wooden spoon edge enters the frame at the corner, dusted with fine green powder. The mood is clean, curious and clinical, with no text, labels or packaging, and no blue cast.

螺旋藻降低美沙酮维持治疗男性的焦虑与压力——随机对照试验发现

BY NOVA CHEN · 2026年10月19日

一项为期12周、双盲随机对照试验显示，每天两次、每次500 毫克的螺旋藻可显著降低焦虑和压力评分。值得注意的是，所有50名受试者均为接受美沙酮维持治疗的男性，结果未必适用于普通人群。抑郁、性功能、药物渴求以及认知测验得分均未出现变化。本文将解析研究结论、未涉及的方面，并在剂量与产品质量上提供实用建议，供对螺旋藻感兴趣的读者参考。

**Approach: Macro science, with Palette C (natural).**

Extreme close-up, shot from a low 30-degree angle, of finely sifted matcha powder in a shallow matte ceramic bowl. A bamboo whisk's tines have just lifted from the surface, leaving a swirl of vivid green foam with a few tiny bubbles. Individual powder grains and the soft ridges of the foam are sharp in the foreground, and the background falls into a creamy blur. Soft side light from a window at left picks out the velvety texture and a faint sheen on the bubbles. The palette is grassy greens, with a worn wooden table in warm brown and a hint of pale daylight. The mood is calm and focused, with a clean, airy, natural feel. The green is the vivid, near-electric tone of fresh matcha. No text, no logos.

研究发现：抹茶在压力工作中的表现胜过单纯咖啡因

BY NOVA CHEN · 2026年10月19日

咖啡因常被视为早晨提升专注的主要来源，但一项针对日本中老年人的随机安慰剂对照试验显示，抹茶可能带来额外益处。一次性咖啡因摄入能提升注意力，而只有坚持每日饮用抹茶，才会在压力测试中提升工作产出。研究者把这种优势归因于抹茶中咖啡因与氨基酸（如 L‑茶氨酸）的协同作用。由于样本仅限日本中老年人且采用的是轻度实验室压力，结果仍需谨慎解读。
