NAD+: cellular energy at the source.

What is NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell in your body. It is required for the reactions that convert food into usable energy, and it is the fuel for the enzyme families — sirtuins and PARPs — that handle DNA repair and cellular maintenance.

NAD+ levels fall substantially with age, and they are drained further by chronic stress, poor sleep, alcohol, and inflammation. At Origin Wellness, NAD+ is prescribed for clients whose main complaints are fatigue, mental fog, and slow recovery — the symptoms most consistent with depleted cellular energy capacity.

How NAD+ works

Inside mitochondria, NAD+ shuttles electrons through the reactions that produce ATP. When NAD+ is scarce, that production becomes less efficient — which is felt as fatigue that rest does not resolve, and as poorer tolerance for physical and cognitive load.

NAD+ also acts as a required substrate for sirtuins, enzymes involved in DNA repair, inflammatory regulation, and metabolic control. Restoring NAD+ availability is therefore studied both as an energy intervention and as a longevity intervention: the same molecule powers metabolism and maintenance.

Researched benefits

NAD+ biology is well established; clinical outcome data for NAD+ supplementation in healthy adults is still developing. We describe it as promising and closely supervised, not proven or guaranteed.

How NAD+ is dosed

There is no single correct dose. NAD+ protocols usually begin with a loading phase of more frequent injections, followed by a lower-frequency maintenance schedule once energy and clarity stabilize.

At Origin Wellness, NAD+ is prescribed as a subcutaneous injection compounded by our licensed 503(A) pharmacy partner. Subcutaneous dosing is generally far better tolerated than rapid intravenous administration.

• Injectable (subcutaneous)

  Injected into fatty tissue, usually the abdomen, on a loading schedule of several times per week before moving to weekly maintenance. Doses are started conservatively because tolerance varies widely; your clinician adjusts upward only as you tolerate it.

At Origin Wellness, dosing is never self-directed. Your protocol is written by a licensed physician after reviewing your assessment, and it is adjusted at follow-up based on your response. Read more about how that review works on our approach page.

Safety, side effects, and who should avoid it

NAD+ is generally well tolerated subcutaneously. Injection-site stinging or redness is common, and higher doses can produce a temporary flushing sensation, mild nausea, or a wave of warmth — which is why doses are started low and titrated up rather than pushed.

Because NAD+ participates in fundamental cellular processes, clinical screening is still required before starting.

• • Not appropriate during pregnancy or breastfeeding.
• • Requires clinician review with an active or prior cancer diagnosis.
• • Requires review with significant kidney or liver impairment.
• • Should be disclosed to any other treating physician alongside your current medications and supplements.

How NAD+ fits into a full protocol

NAD+ restores capacity; it does not manufacture recovery on its own. We look first at sleep, thyroid, iron, B12, and glucose control, because those are the most common reversible causes of the same symptoms.

NAD+ is frequently prescribed alongside a metabolic or longevity protocol, lab work, and a coaching program — Origin Balance for women or Origin Peak for men.
