Approach: the human outcome. Palette: natural.

A tight, low-angle shot of an elderly person's hands gripping a smooth wooden cane at the top of a sunlit garden path. The hands are weathered and slightly tremulous, with visible veins and thin, spotted skin. Behind them, the blurred figure of a seated older man in a cardigan is just recognizable, with his face out of frame. Warm late-morning daylight comes from the side and picks out the grain of the wood and the texture of the skin. The background is soft green foliage and a gravel path in shallow depth of field. The tones are plant greens, honeyed wood and natural skin. A single fresh leaf in vivid electric green sits in the lower foreground. The mood is quiet, honest and reflective, and it suggests fragility without drama.

Frail Seniors Had Lower Blood NAD+. What That Means for NMN/NR

BY HELIX WARD · Oct 26, 2026

A new GeroScience study of 529 older Japanese adults found that those with frailty had slightly lower NAD+ in their blood, with about 13% lower odds of frailty per 1 µmol/L increase. But the study was cross-sectional, included only 32 frail participants, and the difference in medians was just 24 versus 25 µmol/L. The link also weakened after adjusting for hematocrit, suggesting blood cell composition may explain part of it. Here is what the findings really say, why they don't show that NMN or NR prevent frailty, and what to consider if you're thinking about NAD precursors.
