Macro science approach: an extreme close-up of PQQ disodium salt, a deep reddish-orange crystalline powder, heaped on the tip of a stainless steel micro-spatula. The camera is low, at a slight 30-degree angle, with a very shallow depth of field. The nearest crystals are razor sharp, showing faceted, glassy edges and fine granular dust, while the rest of the pile melts into soft blur. A single large softbox from the upper left creates bright specular glints on the crystal faces and a crisp, warm shadow. The backdrop is a smooth, saturated teal-green color field that contrasts strongly with the red-orange subject. A few stray grains rest on the matte teal surface below. A faint electric green reflection runs along the spatula's edge. The mood is precise, curious and scrutinizing, like an ingredient under inspection. No text or labels.

PQQ 在 12 周内提升认知，适用于青年与中老年人

一项双盲、安慰剂对照的临床试验发现，每日摄入 20 mg 吡咯喹啉醌二钠盐（PQQ）可在 12 周后提升 20–65 岁成人的认知得分。不同年龄段的改善出现时间不同：年轻受试者在第 8 周就表现出认知灵活性和处理速度的提升，而 41–65 岁的成年人则在第 12 周出现语言和复杂记忆的改善。需注意的是，作者隶属于生产 PQQ 的三菱瓦斯化学公司，摘要中也未披露样本量。本文将介绍研究发现、局限性以及购买前的解读要点。
