The short answer

NAD-related blood changes are not a direct measure of sustained wellbeing. The cited IV and oral studies were not a head-to-head comparison.

An NAD infusion and an oral NAD precursor are different interventions. An infusion delivers NAD+ into a vein; an oral precursor such as nicotinamide riboside, or NR, is taken by mouth and enters metabolic pathways that can contribute to NAD metabolism. Comparing them by the number of milligrams on an invoice misses the more useful question: what outcome do you want, and what evidence measures it?

For someone considering an expensive wellness appointment in Bali, “raises NAD” is only the beginning of a comparison. It does not say how much better you will feel, how long an effect might last or whether the same result would occur with another intervention.

The infusion study people often cite

A 2019 pilot followed changes in the plasma and urine metabolome during and after an NAD+ infusion. It involved 11 men: eight received NAD+ and three received saline. The observation window was short, and the purpose was to understand the metabolic response. It was not a trial demonstrating longer life or sustained improvement in everyday energy. Original infusion pilot.

The study is useful when discussing what was measured after intravenous administration. Its small size and design make it a poor basis for predicting how a broad population will feel after repeated commercial treatments. “A study exists” and “this package has demonstrated benefit for my goal” are different statements.

What oral NR research adds

A 2018 randomized, blinded crossover trial investigated oral NR over two six-week periods in healthy middle-aged and older adults. It found changes in NAD-related metabolism and reported tolerability under the study conditions. The authors described physiological findings as a basis for further research, rather than proof of an anti-ageing treatment. Original NR trial.

These two studies cannot be put side by side as if participants had been randomized between an infusion chair and an oral supplement. Their populations, designs, measurements and durations differ. Nor does an NR study automatically establish the same effects for NMN or another product sold under the broad “NAD booster” label.

Compare four things that a price list leaves out

Ask for these details in writing before comparing packages. A clear answer may still include uncertainty. That is more informative than a confident promise with no measurable endpoint.

A worked example: the price of an undefined result

Suppose two fictional offers cost 1,500,000 IDR and 600,000 IDR. The first is an infusion appointment; the second is a month of an oral product. Dividing either price by the listed milligrams produces a neat number, but it does not produce a cost per health benefit. The ingredients, routes and exposure are different, and the relevant benefit has not been established by the arithmetic.

A better comparison sheet has columns for total cost, time, exact formulation, evidence for your goal and the planned review point. If you cannot fill the evidence column, write “not established for this goal.” Do not replace it with a speculative percentage of rejuvenation.

These prices are illustrations, not Bodypharm prices or quotations from Bali clinics. Use your actual written offers when making the comparison.

Make an energy complaint specific before buying a solution

If low energy is the reason for searching, describe the pattern first. Note whether the difficulty is sleepiness, breathlessness, muscle fatigue, poor sleep or trouble sustaining a particular activity. Record when it started and what changed around that time. These distinctions give a clinician a more useful starting point than a presumed NAD deficiency.

Choose an ordinary activity as a discussion point: finishing a usual walk, staying awake through an afternoon meeting or completing a familiar workout. It is a record of function, not a diagnostic test. Persistent or new symptoms should be assessed on their merits rather than explained by an unverified biomarker story.

A blood result is one part of the picture

When someone offers a before-and-after NAD test, ask which substance and sample are measured, which laboratory method is used and how the result changes the clinical decision. Also ask whether the same test and timing will be used at follow-up. Two numbers taken under different conditions can look comparable while answering different questions.

Keep the decision anchored to a benefit you can name. The evidence for changing NAD-related measurements is a scientific question. Whether a particular product improves the problem that brought you to the appointment is another question, and it deserves a direct answer.
