The symptomatic group (baseline PSQI Global Score >5, n=10) showed significantly greater improvement in sleep quality after NAD+ administration compared with the non-symptomatic group (n=10) (change from baseline to Day1 of Course 1: -3.8 vs -1.2 points, t-test p=0.0018). No serious adverse events occurred.

Twenty adults (14 women, 6 men), mean age 52.3 years (SD 10.9), mean BMI 22.2 (SD 3.4).
All 20 enrolled participants completed all three courses of dosing and observation; there were no dropouts.
Seventeen adverse events were reported via free text (Grade 1: 11 events; Grade 2: 6 events); no serious adverse events occurred.
Primary outcome: PSQI Global Score. Secondary outcome: PSQI Question 6 score alone.
