What is NAD⁺ (and why is everyone talking about it?)
What Is NAD+ and Why Is Everyone Talking About It?
NAD+, short for nicotinamide adenine dinucleotide, has become one of the most talked-about molecules in wellness, longevity, energy support and cellular health.
At Marylebone Diagnostic Centre, based at 73 Baker Street, London W1U 6RD, we offer NAD+ IV therapy in London as part of our wider IV therapy services.
What Is NAD+?
NAD+ is a natural coenzyme found in every living cell. Your body uses it to support energy production, DNA repair, cell signalling and mitochondrial function.
In simple terms, NAD+ helps your cells convert nutrients into usable energy. It also plays a role in how cells respond to stress and repair internal damage.
Why Are People Talking About NAD+?
NAD+ has gained attention because levels may decline with age. Many people are exploring NAD+ therapy for energy, mental clarity, recovery and healthy ageing support.
However, NAD+ is not a miracle treatment. It should not be described as a cure for ageing, disease or fatigue.
How Does NAD+ Work in the Body?
NAD+ helps transfer energy inside cells. This process is especially important in the mitochondria, often described as the energy centres of the cell.
Your body also uses NAD+ in repair and regulation processes linked to DNA repair and stress response pathways.
NAD+ and Energy
Many patients become interested in NAD+ because they feel tired, drained or mentally slow.
Low energy can have many causes, including poor sleep, stress, dehydration, low vitamin levels, thyroid imbalance, iron deficiency or inflammation.
A private blood test may help identify underlying issues before choosing IV therapy.
NAD+ and Brain Fog
Brain fog can feel like poor concentration, slow thinking or reduced mental sharpness.
Some patients choose NAD+ IV therapy because they want support for mental clarity and cognitive performance.
If symptoms are persistent, testing may be helpful. You can explore our vitamin testing services and wider blood test profiles.
NAD+ IV Therapy vs Oral Supplements
| Option | How It Works | Key Point |
|---|---|---|
| Oral NAD+ precursors | Supplements such as NR or NMN are taken by mouth. | They must pass through digestion first. |
| NAD+ IV therapy | NAD+ is delivered directly into the bloodstream. | This bypasses the digestive system. |
Is NAD+ IV Therapy Safe?
NAD+ IV therapy should be carried out in a professional setting by trained clinical staff.
Before treatment, suitability should be considered. This is important if you are pregnant, breastfeeding, taking medication or have complex medical conditions.
Who May Consider NAD+ IV Therapy?
- Busy professionals
- People experiencing burnout
- Frequent travellers
- People interested in longevity care
- Patients seeking wellness optimisation
- People looking for clinically supervised IV therapy in London
Who Should Be Careful?
- People who are pregnant or breastfeeding
- People with kidney or liver disease
- People with heart rhythm problems
- People with uncontrolled blood pressure
- People with a history of severe allergies
- People taking regular medication
- People with active infection or fever
What Happens During NAD+ IV Therapy?
During treatment, NAD+ is given through an intravenous drip. The infusion is usually delivered slowly while you relax in the clinic.
Some people may feel warmth, mild pressure, flushing or temporary nausea during infusion. These effects are usually managed by adjusting the infusion rate.

Frequently Asked Questions About NAD+
What does NAD+ stand for?
NAD+ stands for nicotinamide adenine dinucleotide. It is a coenzyme found in cells and involved in energy production, DNA repair and cell signalling.
What is NAD+ IV therapy?
NAD+ IV therapy delivers NAD+ through an intravenous drip. This allows it to enter the bloodstream without passing through the digestive system first.
Does NAD+ help with ageing?
NAD+ is linked to cellular processes involved in energy and repair. However, it should not be described as an anti-ageing cure. Research is ongoing.
Can NAD+ help with fatigue?
Some people choose NAD+ IV therapy for energy support. However, fatigue can have many causes. Blood testing may help identify deficiencies or other health issues.
Is NAD+ IV therapy suitable for everyone?
No. Suitability depends on your health, medication, symptoms and medical history. A clinical check should take place before treatment.

By Tharb Faisl
Nicotinamide Adenine Dinucleotide (NAD⁺) is a vital coenzyme present in every cell. It plays critical roles in:
- Energy metabolism – ferrying electrons in mitochondria during glycolysis and the citric acid cycle Wikipedia
- DNA repair and gene regulation – acting as a substrate for PARPs and sirtuins, enzymes tied to longevity and stress responses Wikipedia
- Cell signalling – including roles in calcium release and immune modulation Wikipedia
Sadly, NAD⁺ levels decline as we age—which has been linked to fatigue, slower repair mechanisms, brain fog, and accelerated biological ageing
The science on restoring NAD⁺
To counteract this decline, researchers are exploring two main approaches:
- Oral precursors like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). Early research shows these molecules are safe and increase NAD⁺ in tissues, with signs of improved insulin sensitivity, muscle strength, and neurological function—though large-scale human trials are ongoing Wikipedia
- IV infusion of NAD⁺ itself—marketed as a rapid way to replenish levels directly in the bloodstream.
What the press says
New York Magazine’s “Strategist” asked, “Do NAD+ supplements work to reverse aging, cure jet lag?” The answer: early-stage studies suggest potential, but science hasn’t yet validated dramatic anti‑aging effects Marylebone Diagnostic Centre. (We’ll mention it more in context on Page 2.)
Vogue UK 🔍 questioned if NAD⁺ infusions are “Too Good to Be True.” Experts warn the intact NAD⁺ can’t efficiently penetrate cells—while the benefits may boil down to placebo . Still, enthusiasm persists, especially among biohackers and celebrities The Times+1New York Post+1.
The benefits, hype & scientific reality
Proven and promising benefits
Early clinical studies indicate supplementing NAD⁺ precursors may:
- Boost metabolic and cardiovascular health—studies show improved lipid metabolism and heart function AHA Journal
- Enhance cognitive function—small trials in Parkinson’s and Alzheimer’s patients show improved NAD⁺ brain levels and some symptom relief Vogue
- Support muscle and endurance—NMN has been shown to enhance performance in pre‑diabetes and amateur athletes
- Promote skin health and anti‑aging—it may boost DNA repair in skin cells, diminishing UV damage
IV vs Oral
- Oral precursors (NR/NMN) are smaller molecules that can enter cells effectively, converting to NAD⁺ from within. Safety and bioavailability data are positive, though FDA hasn’t formally approved any Vogue.
- IV infusions deliver intact NAD⁺ directly, bypassing the gut—but lack robust proof to support cellular uptake and long-term benefit .
As Vogue voices: “IV is biologically unlikely to deliver NAD⁺ into cells—suggesting effects may be placebo” .
The hype machine
Hollywood and wellness culture love NAD⁺—Jennifer Aniston, Hailey Bieber, and other celebs have glowing endorsements New York Post. But most researchers urge caution, calling for more rigorous trials before declaring NAD⁺ a fountain of youth.

Is it worth it?
Potential Upsides
- Fast NAD⁺ boost—ideal before big events or when recovering from fatigue
- Professional, controlled setting with same‑day booking on Baker Street
- Comfort and quality compared to generic wellness clinics NADclinicMarylebone Diagnostic Centre
Considerations
- Uncertainty if NAD⁺ enters cells at all via IV
- Placebo effects vs real biochemical impact
- High cost per treatment compared to oral options
Combining approaches
A smart NAD⁺ regimen might combine IV infusions for immediate effect with follow-up oral precursors (e.g., NR or NMN) that can sustain intracellular levels. Don’t forget lifestyle basics: balanced nutrition, exercise, quality sleep, and stress management—all vital for supporting NAD⁺ naturally Marylebone Diagnostic Centre.
Takeaway
- NAD⁺ is essential to energy production, DNA repair, and cellular health—and declines with age.
- Oral boosters like NMN/NR are well-tolerated and show promise, though large trials are pending.
- IV therapy, such as that at Marylebone Diagnostic Centre, offers rapid NAD⁺ replenishment—but the science on cellular uptake is limited.
- Informed use means being clear on costs, setting realistic expectations, and supporting NAD⁺ through lifestyle habits.
