A medically guided approach to cellular energy support within our Anti-Aging Coenzyme Therapy framework
Within Siam Clinic’s Anti-Aging Coenzyme Therapy category, NAD+ Therapy is presented as a medically guided option for individuals who want to explore support for cellular energy metabolism, recovery, and age-related wellness concerns.
Nicotinamide adenine dinucleotide, or NAD+, is a naturally occurring coenzyme found in all living cells. It plays an essential role in redox reactions, mitochondrial energy production, and cellular processes linked to metabolic function and DNA maintenance. Research interest in NAD+ has grown significantly in the fields of aging biology and metabolic health, although the clinical evidence for IV NAD+ in wellness and anti-aging applications remains evolving.
NAD+ is a coenzyme that helps cells convert nutrients into usable energy. It is also involved in pathways related to mitochondrial function, cellular repair mechanisms, and enzyme systems such as sirtuins and poly(ADP-ribose) polymerases, or PARPs.
Because these systems are closely connected to cellular maintenance and metabolic resilience, NAD+ has become a subject of interest in longevity science. However, it is important to distinguish biological plausibility from proven clinical outcomes. While NAD+ biology is well established, the extent to which IV NAD+ therapy improves specific wellness or anti-aging outcomes in humans is still being studied.
NAD+ levels appear to decline with age in multiple tissues, and this has been associated in the scientific literature with changes in mitochondrial function, cellular stress responses, and metabolic health. This is one reason NAD+ has become a focus in aging research.
That said, age-related NAD+ decline does not mean that every symptom of aging is caused by low NAD+, nor does it mean that NAD+ therapy is a universal solution. A medically responsible discussion should view NAD+ as one part of a broader preventive and wellness strategy rather than a standalone answer to complex age-related changes.
NAD+ Therapy typically refers to the intravenous administration of NAD+ under medical supervision. In this setting, the goal is to deliver NAD+ directly into circulation as part of a structured clinical protocol.
A small human pharmacokinetic study found that IV NAD+ increased plasma NAD-related metabolites during and after infusion, showing that direct infusion can alter measurable NAD biology in humans. However, this should not be interpreted as proof of broad anti-aging or disease-related benefit, and treatment decisions should remain individualized.
At Siam Clinic, NAD+ Therapy is not presented as a miracle treatment or a shortcut to reversing aging. It is positioned within our Anti-Aging Coenzyme Therapy approach as a consultation-led option for patients who want to discuss cellular energy support, recovery, and broader wellness planning with a medical team.
Our focus is on appropriate assessment, clear explanation, and medically responsible treatment planning. This means discussing what NAD+ does biologically, what is currently known, what remains uncertain, and whether this therapy is suitable in the context of a patient’s overall health goals.
NAD+ Therapy may be considered by individuals who want to discuss:
Suitability should always be determined individually. NAD+ Therapy is not appropriate for everyone, and it should not replace diagnosis or treatment for underlying medical conditions.
NAD+ Therapy should begin with a medical review rather than a simple consumer transaction. Patients should understand the treatment format, expected duration, possible side effects during infusion, and whether the therapy makes sense for their goals.
This is particularly important because FDA has reported adverse events associated with some compounded NAD+ injectable drugs, including severe chills, shaking, vomiting, and fatigue in certain cases. Product quality, sourcing, sterile compounding standards, and medical supervision therefore matter.
Siam Clinic approaches NAD+ Therapy through the lens of longevity science, preventive wellness, and medically responsible coenzyme support. The emphasis is not on hype, but on helping patients understand the biology, the limitations, the process, and the role this therapy may play within a broader health strategy.
For the right patient, NAD+ Therapy may be discussed as part of a structured wellness plan. The aim is not to promise unrealistic outcomes, but to offer clear guidance and an evidence-conscious clinical experience.
