A Powerful Path to Cellular Rejuvenation
If you’ve been hearing more about NAD+ injections lately, you’re not alone. From biohackers and wellness enthusiasts to elite athletes and busy professionals, many are turning to NAD+ therapy as a powerful tool for restoring energy, improving cognitive performance, and supporting long-term health.
But what exactly are NAD+ injections? How do they work, what benefits can you expect, and what does the process involve?
This guide walks you through everything you need to know before starting your NAD+ injection journey—so you can feel confident, informed, and ready to take your health to the next level.
What Are NAD+ Injections?
Nicotinamide Adenine Dinucleotide (NAD+) is a coenzyme found in every living cell. It plays a vital role in multiple biological processes. At the cellular level, NAD+ is critical for the production of ATP—the energy your cells need to function. It also activates DNA repair enzymes like sirtuins and PARPs, which protect cells from damage and ageing.
NAD+ regulates essential metabolic functions by supporting glucose and fat metabolism and is a key factor in maintaining healthy insulin sensitivity. It also plays a role in brain health, supporting memory, focus, and nerve function. On the immune side, NAD+ helps modulate inflammation and promotes a balanced immune response.
Over time, however, NAD+ levels decline due to ageing, stress, illness, or poor lifestyle habits. This reduction can lead to fatigue, slower recovery, reduced mental clarity, and increased vulnerability to inflammation. NAD+ injections offer a way to replenish these levels quickly and effectively, bypassing the digestive system and delivering NAD+ directly into the bloodstream or muscle for fast cellular uptake.
Why Choose Injections Over Oral Supplements?
While NAD+ precursors like NMN or NR in supplement form are excellent for ongoing maintenance, injections offer faster, more targeted support. They allow NAD+ to enter your system rapidly and in higher concentrations, resulting in quicker improvements in energy, mental clarity, and recovery.
With injections, dosing is more precise and can be adjusted based on your goals—whether you're looking for a performance boost, support during illness, or long-term rejuvenation. You can also choose between intramuscular (IM) and intravenous (IV) methods depending on your comfort and needs. This makes NAD+ injections a highly effective option for those managing fatigue, burnout, high-stress lifestyles, or chronic inflammation.
What to Expect During Your NAD+ Injection Journey
1. Consultation and Assessment
At NAD+ 4u, every client begins with a personalised consultation. This assessment includes a review of your health history, current lifestyle, and wellness goals. We help identify key symptoms—such as fatigue, poor sleep, lack of focus, or slow recovery—and match you with the appropriate dosage and delivery method. Your plan may involve a standalone injection or a multi-session rejuvenation protocol, depending on your needs.
2. The Injection Process: What It’s Like
NAD+ injections are typically administered intramuscularly in the upper arm or gluteal muscle. The process takes around 5 to 15 minutes. The injection itself is quick and minimally invasive. Some people feel a slight warmth or tingling sensation as the NAD+ begins to circulate. We also offer optional vitamin enhancements, such as B-complex or MIC injections, for additional metabolic support.
It’s not uncommon to experience a mild flushing sensation, brief lightheadedness, or a calming effect following the injection. These sensations are normal, temporary, and usually resolve quickly.
3. Aftercare and Immediate Benefits
After your NAD+ injection, it's recommended that you drink water to support hydration and cellular uptake. You may want to avoid intense physical activity for an hour or two, but most people resume their normal routines right away.
Many clients begin to feel benefits within a few hours to a few days. These include a noticeable increase in energy, better focus and mental clarity, more restful sleep, and faster recovery from physical exertion or emotional stress. With regular use, NAD+ injections can become an essential part of a broader wellness strategy.
How Many Injections Do You Need?
The ideal frequency of NAD+ injections varies from person to person. Here are common starting points:
| Goal | Recommended Frequency |
|---|---|
| General wellness boost | 1–2 injections per week |
| Chronic fatigue or burnout | 2–3 injections per week for 2–4 weeks |
| Athletic recovery | As needed post-training or competition |
| Anti-aging & longevity | Weekly or bi-weekly maintenance |
Following the initial protocol, many clients transition to monthly maintenance sessions to preserve their results.
Who Can Benefit from NAD+ Injections?
NAD+ injections are an excellent option for individuals experiencing persistent low energy, reduced motivation, poor cognitive performance, or slow recovery from illness or stress. They also support those with chronic inflammation or oxidative stress and those noticing the effects of ageing in their energy and physical performance.
Additionally, NAD+ therapy is a powerful tool for health-conscious individuals who want to optimise mitochondrial function, promote DNA repair, support long-term metabolic health, and enhance overall resilience.
As always, those with pre-existing medical conditions or who are taking medications should consult a healthcare provider before beginning treatment.
Are There Any Side Effects or Risks?
NAD+ injections are generally very safe and well tolerated. In rare cases, people may experience minor side effects such as nausea, dizziness (especially during high-dose IV treatments), temporary fluctuations in blood pressure, or localised soreness at the injection site.
To minimise the risk of side effects, we recommend staying well-hydrated, starting with lower doses, and receiving treatments under the guidance of trained professionals—such as those at NAD+ 4u.
