Approach: conceptual metaphor. Palette: warm.

A single ceramic mug on a wooden bedside table, filled with a pale, cloudy collagen drink, with a thin ribbon of steam rising from the surface. Camera angle is a low three-quarter view at table height, shallow depth of field. Behind the mug, a rumpled bed with crisp cotton sheets dissolves into soft bokeh. A small brass alarm clock stands beside it, its hands blurred and its face unreadable. Light comes from a warm amber bedside lamp, casting honey-gold highlights on the rim and long copper-toned shadows across the grain of the wood. Powder grains lie scattered on the table next to the mug, one tiny speck of electric green on the lamp's cord switch. The mood is quiet, drowsy and unhurried, the last calm minutes before sleep.

Može li vaš kolagen pomoći pri spavanju? Ispitivanja glicina sugeriraju da možda

BY NOVA CHEN · 27. lis 2026.

Kupili ste kolagen za kožu ili zglobove, ali novi pregled postavlja pitanje: može li glicin iz njega utjecati na kvalitetu sna? Suplementi glicina pouzdano podižu njegovu koncentraciju u krvi, a sva tri klinička ispitivanja spavanja s glicinom pokazala su korist na barem jednom mjerenju. Peptidi kolagena smanjili su broj buđenja u jednoj studiji i umor u drugoj, ali nisu nadmašili alfa‑laktalbumin u izravnim usporedbama. Nitko još nije testirao je li glicin zaista taj mehanizam. Ovdje su doza, vrijeme uzimanja i ograničenja koja trebate znati.
