NAD — Nicotinamide Adenine Dinucleotide — is not a vitamin, a mineral, or an amino acid. It is a coenzyme: a molecule that sits inside every cell in the human body and enables the biochemical reactions that keep those cells alive, functional, and capable of repair. Without NAD, no cell can produce energy, repair its own DNA, regulate its internal clock, or respond to stress. It is not a supporting player in cellular biology — it is infrastructure.
The NAD Express delivers 100mg of NAD+ directly into the bloodstream in a single 30 to 45 minute session. At this dose, IV NAD bypasses the multi-step conversion pathway that oral NAD precursors — NMN, NR, and niacin supplements — must travel through before producing active NAD inside cells, delivering the finished molecule into circulation where tissues can take it up immediately.
NAD exists in two primary forms inside cells: NAD+ (the oxidised form) and NADH (the reduced form). The ratio between them — and the total pool available — determines how effectively a cell generates energy, handles oxidative stress, and repairs DNA damage. The problem is that total NAD+ availability declines steadily with age, falling by approximately 50 percent between the ages of 40 and 60 in most tissues. This is not a marginal decline — it is one of the most consistent and well-documented molecular changes associated with ageing across species.
Several factors accelerate this decline beyond the baseline of age. Chronic psychological stress elevates CD38 — an enzyme that consumes NAD+ as part of the inflammatory response — dramatically increasing the rate of depletion. Alcohol consumption, sleep deprivation, UV radiation, and any condition producing sustained oxidative stress all compete for the same NAD+ pool. In Dubai's high-intensity environment, where professional pressure, disrupted sleep, and year-round UV exposure coexist in the same population, accelerated NAD+ depletion is not an edge case — it is the norm.

NAD+ is the essential electron carrier in the mitochondrial electron transport chain — the process through which cells convert nutrients into ATP. Every cycle of the Krebs cycle, every step of beta-oxidation, and every pass through the electron transport chain consumes NAD+ and produces NADH. Without adequate NAD+, these cycles slow, and the cell's energy output drops in proportion. This is the primary mechanism behind NAD-related fatigue — not a shortage of fuel, but a shortage of the molecule that processes that fuel into usable energy.
Sirtuins are a family of seven proteins that regulate gene expression, DNA repair, inflammation, and cellular stress response. All seven sirtuins are NAD+-dependent — they cannot function without it. When NAD+ levels are adequate, sirtuins actively suppress inflammatory pathways, promote mitochondrial biogenesis, regulate circadian rhythms, and stimulate the production of new mitochondria in cells that need higher energy output. When NAD+ is depleted, sirtuin activity falls, and the cellular maintenance functions they perform begin to fail silently — contributing to the progressive functional decline associated with ageing and chronic stress.
PARP enzymes — Poly(ADP-ribose) polymerases — are the cell's primary DNA repair mechanism, activated whenever the cell detects single or double-strand DNA breaks. PARP activation is one of the largest consumers of NAD+ in the cell, and in environments with high DNA damage rates — UV exposure, pollution, oxidative stress — PARP activity can deplete the entire available NAD+ pool rapidly. This creates a direct competition: cells under environmental stress consume NAD+ for DNA repair faster than energy production and sirtuin function can be sustained. Restoring NAD+ resolves this competition by expanding the total pool available, allowing repair, energy production, and cellular regulation to proceed simultaneously rather than competing for a depleted resource.
NAD+ levels oscillate naturally across the 24-hour cycle, and these oscillations are directly coupled to the circadian clock — the internal timing mechanism that regulates sleep, metabolism, hormone secretion, and immune function. Disrupted circadian rhythm — from shift work, frequent long-haul travel, or chronic sleep irregularity — dysregulates NAD+ cycling, which in turn impairs the sirtuin activity and mitochondrial function that the circadian clock coordinates. IV NAD restores the total pool that these cycles draw on, supporting the resynchronisation of circadian biology in people whose rhythms have been repeatedly disrupted.
NMN and NR supplements have attracted significant attention in longevity research — and the underlying science is legitimate. Both are NAD precursors that the body converts into NAD+ through enzymatic pathways. The limitation is conversion efficiency. NMN must cross the intestinal wall via a specific transporter, then be converted to NR, then to NMN again inside the cell, then to NAD+. NR follows a different but equally multi-step route. Both pathways are limited by enzyme availability, gut health, and the efficiency of the transporters involved — all of which decline with age and under the conditions that cause NAD+ depletion in the first place.
IV NAD+ delivers the finished molecule directly into plasma, where it is taken up by tissues through established transport mechanisms without conversion dependency. Clinical pharmacokinetic data shows that IV NAD produces peak plasma concentrations several orders of magnitude higher than what is achievable orally, and that cellular uptake begins within minutes of the infusion starting. For people who have been taking oral NMN or NR and not noticing the expected results, this is usually why.
NAD+ infusions have a distinct physiological profile that sets them apart from other IV treatments. At 100mg delivered over 30 to 45 minutes, most people experience transient sensations during the infusion — mild chest tightness, a feeling of pressure or warmth, slight nausea, or muscle cramping that comes and goes in waves. These are not adverse reactions — they are the expected result of NAD+ entering circulation and immediately activating energy-dependent pathways in multiple tissue systems simultaneously. They resolve completely as the infusion ends and are managed by slowing the infusion rate if needed. Our nurses are experienced with NAD infusions specifically and will adjust delivery speed throughout the session to keep the experience comfortable.
The NAD Express is suited for anyone whose primary goals are cognitive performance, sustained energy, healthy ageing, or recovery from a period of intense physical or psychological demand. It is particularly well used by executives and professionals seeking sustained cognitive output, people recovering from burnout or prolonged illness, frequent travellers dealing with disrupted circadian rhythms, anyone actively investing in longevity protocols, and people over 40 who want to proactively address the NAD+ decline that begins in earnest during this decade.
For NAD combined with the broader energy metabolism support of B vitamins, amino acids, and mitochondrial cofactors, the Energy Booster Express and Energy Booster Max build on the NAD foundation with a full multi-compound formula. For people interested in a structured longevity protocol across multiple sessions, our clinical team can advise on combining the NAD Express with complementary drips based on your specific health profile and goals.

This is a normal and expected response. As NAD+ enters the bloodstream, it activates energy-producing and repair pathways in multiple tissues simultaneously — including cardiac and smooth muscle — which produces transient sensory effects. These feelings come in waves, are not harmful, and resolve completely when the infusion ends. Slowing the infusion rate reduces their intensity. Our nurses are trained specifically in NAD infusion delivery and manage the rate throughout the session.
NMN and NR are precursors that the body must convert into NAD+ through multi-step enzymatic pathways before they become active. Oral absorption is limited, conversion efficiency declines with age, and the process depends on gut health and transporter availability. IV NAD delivers the finished molecule directly into circulation — no conversion required — at plasma concentrations that oral precursors cannot approach regardless of dose.
Most people notice improved mental clarity and alertness within hours of the session. Physical energy improvements typically develop over 24 to 48 hours as cellular ATP production responds to restored NAD+ availability. The full effect across multiple biological systems — sleep quality, cognitive performance, physical stamina — builds over the days following the infusion.
For general maintenance and cognitive performance, once every two to four weeks is a common protocol. For more intensive goals — burnout recovery, longevity protocols, or preparation for a period of high demand — weekly sessions for four to six weeks followed by monthly maintenance is a structured approach our clinical team regularly recommends.
Yes. 100mg is a clinically used single-session dose that produces meaningful plasma and tissue NAD+ restoration. Higher doses — up to 500mg or more — are used in more intensive protocols, particularly for addiction recovery and neurodegenerative support, but at significantly longer infusion times and with more pronounced transient sensations. For general wellness, cognitive, and energy goals, 100mg is the appropriate starting point and is effective as a regular maintenance dose.
Yes. NAD pairs particularly well with the Vitamin C Express — Vitamin C supports the redox cycling that maintains the NAD+/NADH ratio — and with the Glutathione Max for combined antioxidant and cellular repair support. Your nurse will advise on combinations and spacing based on your goals.
