Approach 4, conceptual metaphor, in palette D, bold color field.

A single AA-style cylindrical battery, shown as a real physical object with a matte metal casing, stands upright at the center of a saturated tomato-red seamless paper backdrop. Its top half is bright and glossy, while the lower half is scuffed and dull. A thin, crisp line of electric green liquid light fills the clear gauge window along its side, stopping about three-quarters of the way up. Three smaller, identical dead batteries lie tipped over in the foreground, slightly out of focus, to suggest the rival compounds. The camera sits at a low three-quarter angle with a shallow depth of field. A hard, warm key light from the upper left casts a sharp, long shadow across the red surface. The mood is punchy and skeptical: one cell charged, the others spent.

NMN, NR i NADH: jedan poboljšava izdržljivost, nijedan ne smanjuje umor

BY NOVA CHEN · 29. lis 2026.

Novi mrežni meta‑analiza od 27 studija s 1 599 odraslih uspoređuje NMN, NR, NADH i nikotinamid, a rezultati nisu ono što marketinški materijali obećavaju. NMN je pokazao dozu‑zavisno poboljšanje izdržljivosti, s velikim učinkom pri visokoj dozi. NADH je dao dobitke u kognitivnim rezultatima, ali uglavnom u grupama s kognitivnim oštećenjem i rezultat je osjetljiv na utjecajne studije. Iznenađujuće, nijedan prekursor nije značajno poboljšao percepciju umora niti kvalitetu sna. Ovdje je prikazan rang, njegove granice i tko bi (i tko ne bi) trebao uzimati ove dodatke.

$Approach: macro science. Palette: bold color field. Extreme close-up of glycine crystals, glassy colorless prisms with sharp faceted edges and slightly frosted surfaces. They lie in a loose, diagonal cluster across a smooth saturated mustard-yellow backdrop. The camera is low, about 20 degrees above the surface, with a very shallow depth of field. A few crystals in the foreground are razor sharp, and the rest melt into soft golden bokeh. A large softbox from the upper left gives bright, clean highlights along the crystal edges. Light refracts through the prisms and throws small warm caustic glints onto the yellow surface. A single crystal catches a faint electric green sparkle at its tip. The mood is crisp, energetic and optimistic, like a microscopy photograph styled for a magazine. No text.$

3 grama slatke aminokiseline ublažavaju umor uz nedostatak sna

BY DR. SYNAPSE · 22. lis 2026.

Nedovoljno spavanja i osjećaj umora? Jeftina, blago slatka aminokiselina mogla bi poboljšati sljedeći dan, bar u malom ispitivanju. U studiji Ajinomoto, zdravim dobrovoljcima kojima je spavanje skraćeno za četvrtinu tri uzastopna dana, dali su **3 g glicina prije spavanja**. Oni su sljedeće jutro izvijestili o znatno manjem umoru i o boljem rezultatu u testu reakcijskog vremena.
