A softly lit editorial still life on a pale oat-colored linen surface, shot from a slightly elevated three-quarter angle in a wide landscape frame. At center-left, a small matte white ceramic dish holds a modest pile of fine off-white powder, with a tiny brushed-brass measuring spoon resting beside it. Next to the dish stands a minimalist amber glass supplement bottle with a plain cream label and no readable text. A few capsules spill casually across the linen, some translucent and some opaque ivory.

On the right side of the composition, a ripe blood orange cut in half and a handful of raw almonds sit on a light ash-wood board. A sprig of fresh rosemary adds a muted green accent. A sheer glass of water catches the light and throws a soft, rippled caustic pattern across the fabric.

In the background, out of focus, a woman's hand in a soft sage-green knit sleeve rests near a ceramic mug. This suggests a calm morning routine without showing a face. Behind her, a tall window casts diffused, golden-hour light from the upper left, with gentle shadows and a creamy, shallow depth of field.

The palette is warm and restrained: oat, ivory, terracotta, sage, and amber, with a single pop of coral from the blood orange. A thin, abstract line of muted terracotta paint, like a brushed arc, sweeps across the upper right background. It subtly evokes a rising curve without becoming a literal chart.

The mood is calm, trustworthy, and contemporary, like a premium wellness and science journal feature. The image has crisp focus on the powder and bottle, natural film-like grain, soft contrast, and generous negative space in the upper third for headline overlay. It looks like a high-end editorial photograph with no text, logos, or futuristic elements.

Eerste menselijk bewijs voor NMN: 250 mg per dag verhoogt spierinsulinegevoeligheid met ongeveer 25 % bij prediabetische vrouwen

BY DR. SYNAPSE ·

NMN wordt al jaren geprezen in de longeviditeitsmarkt, maar menselijk bewijs was schaars tot een proef van Washington University in 2021 die in *Science* verscheen. Bij postmenopauzale vrouwen met prediabetes en overgewicht of obesitas verbeterde een dagelijkse dosis van 250 mg NMN gedurende 10 weken de spierinsulinegevoeligheid met ongeveer 25 %. Ook het spierinsulinesignaal en de genexpressie die bij spierremodellering horen reageerden positief, terwijl de placebogroep geen veranderingen liet zien. De voordelen waren echter beperkt en de studie toonde niet aan dat NMN de bloedsuikerspiegel verlaagt of prediabetes omkeert.
