NAD+
Injections
Recharge your cells, sharpen your mind, and support healthy ageing with the most powerful co-enzyme in your body.
The molecule behind energy,
repair & longevity
NAD+ (Nicotinamide Adenine Dinucleotide) is a co-enzyme found in every single cell in your body. It plays a critical role in converting food into energy, repairing damaged DNA, regulating inflammation, and activating proteins that slow the ageing process.
The problem? NAD+ levels decline significantly with age ā by as much as 50% between your 40s and 60s. This decline is linked to fatigue, cognitive decline, slower recovery, and reduced cellular resilience. Our NAD+ injections deliver this essential molecule directly into the muscle for fast, effective absorption.
Why inject
rather than supplement?
Oral NAD+ supplements are available, but the bioavailability is limited ā much of it is broken down before it reaches the bloodstream.
Intramuscular injection delivers NAD+ directly into the muscle tissue, where it is absorbed rapidly into the bloodstream at a far higher concentration than oral supplementation.
At THRIVE, all injections are administered by our clinically trained practitioner, Lauren, who brings NHS-level expertise to every session.
What NAD+ can do for you
NAD+ supports multiple biological systems. Here are the most commonly reported benefits from regular injections.
Energy & Vitality
NAD+ is essential for mitochondrial function ā the process that converts nutrients into ATP, your body's energy currency. Replenishing NAD+ restores cellular energy production at its source.
Mental Clarity
NAD+ supports neurotransmitter synthesis and brain cell protection. Clients frequently report sharper focus, improved memory, and reduced brain fog within days of treatment.
DNA Repair & Longevity
NAD+ activates sirtuins ā proteins involved in DNA repair and cellular longevity. Higher NAD+ levels are linked to slower biological ageing and improved cellular resilience.
Recovery & Performance
Athletes use NAD+ to accelerate muscle repair, reduce exercise-induced inflammation, and return to peak performance faster after intense training.
Sleep Quality
NAD+ plays a role in regulating circadian rhythms. Many clients report deeper, more restorative sleep ā particularly when combined with our magnesium IV drips.
Immune Support
By reducing oxidative stress and supporting cellular repair, NAD+ helps your immune system function more efficiently ā important for both prevention and recovery.
Is NAD+ right for you?
NAD+ injections are suitable for a wide range of clients. You may benefit if you identify with any of the following.
Experiencing mental fatigue, low energy, or afternoon slumps despite adequate sleep.
Looking to enhance performance, speed up recovery, or break through a plateau.
Proactively supporting longevity and countering the natural decline of NAD+ with age.
Those who invest in their health and want a clinically backed way to boost vitality.
Chronic tiredness or brain fog that doesn't improve with rest alone.
Interested in science-backed interventions to slow biological ageing.
Your NAD+ session
step by step
Consultation
Before your first session, Lauren will take a brief health history to ensure NAD+ is suitable for you and to understand your goals. This takes around 5 minutes.
Preparation
The injection site (usually the upper arm or thigh) is cleaned and prepared. The dose is drawn and you'll be made comfortable before we begin.
The Injection
The intramuscular injection takes less than 60 seconds. Most clients describe it as a mild pressure ā similar to a vaccine. The whole appointment is typically 15ā20 minutes.
Post-Treatment
You can resume normal activities immediately. Stay well hydrated. Many clients notice benefits within hours; others experience the full effect over 24ā72 hours.
Ongoing Programme
For best results, we recommend a course of injections. Lauren will advise on the ideal frequency based on your goals ā typically weekly or bi-weekly initially.

Common questions
Most clients describe it as a mild pressure or a brief sting ā similar to a routine vaccine. The discomfort lasts only a second. Lauren's clinical background means the procedure is swift and precise, and she will make sure you feel comfortable throughout.
Many clients notice increased energy and mental clarity within 24ā72 hours of their first injection. Those undergoing a course typically report more pronounced and lasting effects after the second or third session.
We generally recommend weekly injections for the first 4 weeks, followed by a maintenance schedule of once every 2ā4 weeks. Lauren will provide personalised guidance based on your goals and response to the initial sessions.
NAD+ injections are generally very well tolerated. Some clients experience mild soreness at the injection site for 24 hours. Rarely, some report a temporary flushing sensation or mild headache ā these resolve quickly. Lauren will discuss your full health history before proceeding.
Absolutely ā and we actively encourage it. NAD+ pairs particularly well with our energy IV drip, B12 injection, and longevity blood test panel. Ask Lauren about our combination packages.
