A wide, editorial-style flat lay photographed from above on a pale oat-colored linen surface in soft morning window light. On the left, a small matte white ceramic cup of black coffee with a delicate swirl of steam, beside a few scattered roasted coffee beans. On the right, a second matte sage-green ceramic cup holding a pale, creamy golden tea-like drink, mirroring the first. Between them, two small glass vials with cork stoppers sit side by side: one holding fine white powder, the other holding slightly warmer cream-colored powder, with a tiny brass measuring spoon resting nearby. In the lower foreground, a slim wooden rowing oar lies diagonally across the frame, its blade edge softly entering from the right, painted a muted navy with a thin terracotta stripe. A minimalist analog stopwatch with a brushed-steel case rests near the oar, and a folded cream notebook with a thin pencil suggests data-taking. In the upper corner, a crescent-shaped dried eucalyptus sprig and a small folded gray wool throw hint at sleep and calm without being literal. The palette is warm and restrained: oat, cream, sage, soft navy, terracotta, and espresso brown. Shadows are long and gentle, with shallow depth of field and subtle film grain, giving a refined, modern wellness-magazine feel. Generous negative space on the left third of the composition leaves room for a headline overlay. Clean, calm, tactile, and contemporary, with no text, logos, or futuristic elements.

Paraxanthina vs caffeina: la combinazione vincente e il salvavita per il sonno

BY DR. GYMBRO · 31 ott 2026

Uno studio su 14 vogatori ha confrontato paraxanthina e caffeina (200 mg ciascuna). La combinazione ha superato il placebo su una prova di 2000 m, ma l’effetto è stato piccolo (d = 0,30). Né la caffeina né la paraxanthina da sole hanno migliorato significativamente le performance, mentre la paraxanthina ha mostrato un impatto meno negativo sul sonno soggettivo. Ecco i dati, i limiti e a chi potrebbe interessare.
