What Is NAD+ Therapy and How Does It Work?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell that plays a central role in cellular energy production. NAD+ therapy typically delivers NAD+ by IV infusion, and at Zest 4 Wellness in Columbia, Maryland, it is offered under medical supervision after an evaluation, with an honest discussion of the current evidence.

What is NAD+?

NAD+ is derived from vitamin B3 and is essential for the chemical reactions that convert food into cellular energy. NAD+ levels naturally decline with age, which is the rationale behind NAD+ therapy: the idea that raising levels could support energy, recovery, and healthy aging.

How NAD+ therapy is given

• IV infusion is the most common route, typically over one to several hours in a clinic
• Courses are usually repeated, such as a loading series followed by maintenance sessions
• NAD+ precursors, including nicotinamide riboside, are also being studied
• Dosing is individualized and reviewed by the clinical team

What the current evidence says

Human data on IV NAD+ is still limited. Small studies have reported improved fatigue scores in specific conditions, and a randomized pilot trial found single infusions were generally well tolerated, but reviewers have concluded the evidence remains preliminary and insufficient to support routine wellness use. NAD+ therapy is not FDA-approved for wellness claims, and no standard dosing exists, so most marketing claims run ahead of the science.

Who may consider NAD+ therapy

• Adults interested in energy or recovery support who understand the evidence is emerging
• Patients who have completed a medical evaluation and candidacy review
• Patients with realistic expectations, since individual responses vary
• Patients willing to be monitored during infusions

Safety considerations

Infusions can cause temporary discomfort, including nausea, flushing, or abdominal symptoms, and IV placement carries the usual risks of vein irritation or infection. That is why NAD+ at Zest is delivered by trained staff under physician supervision, never as an unsupervised at-home or walk-in service.
