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 poboljšava memoriju za 12 nedelja i kod mlađih i kod starijih odraslih

BY NOVA CHEN · 25. окт 2026.

Dvostruko slep, placebo‑kontrolisan eksperiment je otkrio da 20 mg dnevno PQQ disodijum soli poboljšava rezultate memorije kod osoba od 20 do 65 godina posle 12 nedelja. Efekti su se pojavili u različitim periodima: mlađi su do nedelje 8 pokazali napredak u kognitivnoj fleksibilnosti i brzini obrade, dok su stariji (41‑65 god) unapredili verbalnu i složenu memoriju tek u nedelji 12. Ipak, autori studije rade za Mitsubishi Gas Chemical, proizvođača PQQ‑a, i apstrakt ne navodi veličinu uzorka. Evo šta je studija pokazala, šta nije i kako da je protumačite pre nego što kupite suplement.
