**Approach:** Conceptual metaphor. **Palette:** Bold color field (mustard yellow).

Straight-on, slightly elevated camera view of a pair of identical brass balance scales on a saturated mustard-yellow seamless backdrop. The pans sit perfectly level. One pan holds a small mound of fine white crystalline powder, the other holds an almost identical mound. A third, smaller pan lies tipped and lighter off to the side. Between the scales, a single translucent glass tube coils like a gut, with a tiny electric green (#00e676) glow inside it. This is the only green in the frame. Lighting is soft, directional studio light from the upper left, with crisp, gentle shadows on the yellow surface and warm metallic highlights on the brass. Mood: playful, curious, quietly skeptical. Photorealistic with sharp macro detail on the powder grain and the glass.

NMN vs NR: Prvo izravno ljudsko sučeljavanje otkriva neriješenost i iznenađenje u crijevima

Godinama se NMN prodaje kao vrhunska alternativa NR‑u. Prvi izravni ljudski test NMN‑a, NR‑a i nikotinamida pokazao je da oba suplementa podižu razinu NAD+ u krvi, dok nikotinamid to ne čini. Zanimljiv obrat: crijevni mikroorganizmi pretvaraju NR i NMN u nikotinsku kiselinu, snažan pojačivač NAD+‑a u eksperimentima na krvi. To postavlja neugodno pitanje o cijeni, načinu djelovanja i ulozi mikrobioma.
