Eligibility for NAD injection therapy is determined by a licensed healthcare provider during a medical evaluation. Because NAD injections involve prescription medication and structured dosing protocols, providers typically review a patient's medical history, current medications, and overall health goals before approving treatment. This screening process helps ensure the therapy is appropriate and that individuals can safely follow an injection-based protocol.
Adults interested in supporting cellular energy production, recovery, metabolic health, or cognitive function may be considered candidates for NAD injection therapy, provided a clinician determines the treatment aligns with their medical profile. Some programs may also evaluate factors such as lifestyle demands, stress levels, and existing wellness goals when determining whether NAD injections are suitable.
Patients who qualify are usually enrolled in structured treatment plans that outline dosage levels, injection frequency, and follow-up recommendations. Because these protocols vary between providers, individuals researching NAD therapy often review dosing ranges and program structures before beginning treatment. Before starting, understanding
where to inject NAD is an equally important part of administration preparation, as site selection and technique are covered once a prescription is issued. For a breakdown of common dosing tiers and structured treatment protocols, see our
