    Can NAD supplements help multiple sclerosis?

    NAD-related treatments are being investigated in multiple sclerosis, but the reviewed evidence does not establish a supplement as a treatment for MS. A clinical trial of nicotinamide riboside is testing whether it slows progression alongside standard care. A trial plan is not a positive result.

    The rationale concerns cellular metabolism

    NAD participates in energy-related and other cellular processes. Mechanistic interest does not establish that increasing a blood measurement protects nerves, repairs myelin or reduces disability in people with MS. Tissue effects and clinical outcomes must be measured directly. [1][2]

    NORSEMAN is testing a specific intervention

    The study hospital describes a randomized, double-blind comparison of oral nicotinamide riboside with placebo as an addition to standard care in progressive MS. Its goals concern sustained disability progression measured using clinical scales and functional tests. It is not a study of every NAD-labelled product or infusion. [3]

    Enrollment and endpoints are not proof of benefit

    The hospital page, updated in July 2026, describes the study and enrollment progress rather than reporting treatment efficacy. It lists public research and hospital support as well as Elysium Health. These details help identify the research; they cannot establish that it works. [3]

    Keep established MS care in place

    Imagine a product advertisement uses the trial registration to claim proven nerve repair. Ask for published outcomes rather than the study description. Discuss interest in supplementation or research participation with the MS team without replacing prescribed disease management. [3][4]
