NAD+ Injections

Support your energy, focus, and overall health with NAD+ self-injection pens.

NAD+ (Nicotinamide Adenine Dinucleotide) is a natural substance found in every cell of your body. It helps create energy, repair cells, and keep your brain and body working at their best. But as we age, NAD+ levels drop, which can lead to tiredness, brain fog, and slower recovery.

UK Meds makes it easy to feel your best. Our NAD+ pens are simple to use at home, giving you the flexibility to boost your wellbeing on your own schedule – without the need for a clinic visit.

Want to boost your energy, stay mentally sharp, and age in a healthier way? NAD+ therapy could help.

NAD+ injections are a fast and efficient way to boost your body’s levels of Nicotinamide Adenine Dinucleotide (NAD+), a vital molecule that helps power your cells. These injections are popular in the fields of health optimisation, longevity, and anti-ageing _[1][2].

By delivering NAD+ directly into your bloodstream, injectable treatments may support:

• Improved energy production at the cellular level
• Enhanced brain function and mental clarity
• Support for healthy ageing and DNA repair
• Faster recovery from stress, fatigue, or illness

Understanding NAD+ (Nicotinamide Adenine Dinucleotide)

NAD+ is a coenzyme found in every cell of your body _[3][4]. It plays a key role in:

• Converting food into usable energy (ATP)
• Repairing damaged DNA and maintaining cell health
• Supporting metabolism and mitochondrial function
• Activating longevity-related proteins (sirtuins)

Without enough NAD+, your cells may struggle to perform basic functions—leading to fatigue, brain fog, and signs of premature ageing.

Is NAD the same as NAD+?

No, NAD and NAD+ are related, but they’re not exactly the same. NAD (nicotinamide adenine dinucleotide) is the general name for a molecule that exists in two forms: NAD+ and NADH.

NAD+ is the active form your body uses in important processes like turning food into energy and repairing DNA. It works by picking up electrons and changing into NADH. NADH then gives away those electrons during other reactions and turns back into NAD+.

This back-and-forth cycle helps your cells stay healthy and energised.

Why NAD+ Levels Decline With Age

As we get older, our natural NAD+ levels start to drop. This decline can be made worse by:

• Stress and poor sleep
• Excess alcohol or sugar consumption
• Chronic illness or inflammation
• Exposure to toxins and pollutants

This reduction in NAD+ has been linked to age-related health issues such as low energy, weakened immunity, poor memory, and reduced cellular repair _[5][2].

What Makes Injectable NAD+ Different From Pills or Patches?

While NAD+ supplements come in various forms, such as capsules, patches, or oral treatments, injectables offer unique benefits in terms of speed and effectiveness.

NAD+ injections are often chosen by people who want noticeable results quickly, especially if they are feeling run-down, have demanding lifestyles, or are actively pursuing wellness and longevity goals.

NAD+ injections deliver this essential coenzyme straight into your bloodstream, where it can quickly get to work supporting your cells. Unlike oral supplements, which must pass through the digestive tract, injections allow NAD+ to be absorbed directly and efficiently.

The Role of NAD+ in Cellular Energy (ATP) Production

Every cell in your body relies on NAD+ to generate energy. It does this by helping your mitochondria (the powerhouses of your cells) convert nutrients into ATP, your body’s main energy currency¹.

Without enough NAD+, your cells may struggle to:

• Maintain normal energy levels
• Carry out vital functions such as repair and regeneration
• Combat oxidative stress and inflammation

This is why NAD+ therapy is often associated with improved energy, clearer thinking, and better overall vitality ^[6].

How Injecting NAD+ Bypasses the Digestive System

When taken by mouth, NAD+ must be broken down by the digestive system and absorbed through the gut. This process can reduce how much of the active ingredient actually makes it into your bloodstream.

With injections, NAD+ bypasses the digestive system entirely and enters the bloodstream directly. This offers several key benefits:

• Higher absorption and bioavailability
• Faster onset of effects – often within hours
• More predictable and consistent results

This makes injectable NAD+ ideal for people who need quick, noticeable support, whether for brain fog, fatigue, stress, or active recovery.

Scientific Evidence Supporting NAD+ Therapy

Research into NAD+ therapy is growing, with studies highlighting its potential to support various aspects of health and ageing:

• Energy metabolism: Studies show that NAD+ is vital for mitochondrial function and ATP production, directly influencing how energised you feel^[1].
• Brain function: NAD+ may support cognitive performance and protect neurons against age-related damage ^[7].
• Cell repair: NAD+ activates sirtuins, a group of proteins that help repair DNA and regulate ageing ^[8].
• Anti-ageing benefits: Animal studies have linked higher NAD+ levels with improved lifespan and delayed age-related decline ^[9].

NAD+ (short for Nicotinamide Adenine Dinucleotide) is a natural molecule found in every cell of your body. It helps turn the food you eat into energy, repairs cells, and keeps your brain and body working as they should.

As you age, your NAD+ levels naturally fall. This drop can leave you feeling tired, foggy-headed, slower to recover after exercise, and generally low in energy. NAD+ therapy works by boosting these levels, helping your body feel stronger, sharper, and more refreshed.

Restoring NAD+ may help you feel more energised, focused, and clear-headed, while also supporting healthy ageing and your long-term wellbeing.

Who Can Benefit from NAD+ Therapy?

NAD+ therapy may be right for you if you're feeling low on energy, struggling with focus, or want to support healthy ageing.

If you're unsure whether NAD+ therapy is right for you, our team can guide you based on your personal health goals and lifestyle.

Injections vs NAD+ Oral Capsules

NAD+ capsules are widely available and easy to use, but they may not work as quickly or effectively as injections.

Oral capsules are a good choice if you want something quick and easy. But if you're looking for faster or stronger effects, NAD+ injections may be more suitable. Everyone's body is different, so results can vary.

NAD+ Injections vs NMN and NR (Precursors)

NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside) are common supplements known as NAD+ precursors. This means your body has to convert them into NAD+ before they can be used.

• NMN/NR: Go through several conversion steps in the body. How well this works can depend on your age and overall health.
• NAD+ Injections: Deliver NAD+ directly in its active form, so your body can use it straight away without any conversion.

NMN and NR can be helpful for everyday support. But if you want quicker or stronger results, such as during times of stress, tiredness, or age-related decline, NAD+ injections may be more effective.

Injections vs IV Drips

Both injections and IV drips deliver NAD+ straight into your bloodstream, but the main difference is how and where you take them:

• IV Drips: Usually done in a clinic. They take 1-2 hours and are often used for high doses or longer treatment plans.
• Injections: Quick and easy to do at home. They only take a few minutes and offer more flexibility.

Injections are ideal if you want a convenient and time-saving way to get the same potential benefits without going to a clinic.

Which NAD+ Option Is Best for Me?

The right choice depends on your health goals, lifestyle, and personal preferences. Here's a simple guide:

If you're not sure which option is right for you, speak to a registered healthcare professional or book a clinical consultation. Everyone's needs are different, so it's best to get advice tailored to your health and goals.

What are the benefits of NAD+ Injections?

NAD+ injections offer a range of health benefits by boosting your body’s natural energy and repair systems. Here’s a quick look at how they can help:

NAD+ injections can give your body a quick boost, but your everyday habits also matter. Simple lifestyle changes can help your body make and maintain healthy NAD+ levels over time. This may support long-term cell health and slow the natural drop in NAD+ that comes with ageing.

Diet and Foods That May Help Boost NAD+

Eating a balanced diet with plenty of B vitamins can help your body make more NAD+. Nutrients like niacin (vitamin B3) and tryptophan are key building blocks your cells use to create it _[12].

Foods that may support NAD+ production:

• Avocados – packed with B vitamins and healthy fats
• Oily fish (like salmon, mackerel, and sardines) - rich in B vitamins and support energy production in cells
• Dairy products (like yoghurt and cheese) - contain both niacin and tryptophan
• Leafy greens - such as spinach and kale, full of antioxidants
• Whole foods over processed grains - better for reducing inflammation and supporting overall health

Drinking enough water and cutting down on sugar, alcohol, and processed foods can also support healthy NAD+ levels and metabolism.

Exercise and Sleep for Cellular Health

Regular movement and rest are crucial to keeping your mitochondria and NAD+ functioning efficiently _{[13][14][15][16]}. Exercise increases NAD+ turnover, helping your body make better use of it.

• Aerobic exercise: Running, walking, swimming, or cycling can stimulate mitochondrial activity and NAD+ production
• Strength training: Helps regulate blood sugar and reduce oxidative stress
• Sleep: Deep rest supports DNA repair and hormonal balance, both of which depend on NAD+-powered enzymes

Aim for at least 150 minutes of moderate activity per week and 7–9 hours of good-quality sleep each night, as advised by the NHS.

Reducing Stress to Protect Your NAD+ Levels

Long-term stress can lower your NAD+ levels by increasing inflammation and oxidative stress in the body. Supporting your nervous system may help slow down NAD+ loss and improve your overall wellbeing.

Simple ways to manage stress _[17][18]:

• Try mindfulness, meditation, or breathing exercises
• Make sure you're getting enough sleep
• Spend time outdoors, move your body, or enjoy creative hobbies
• Cut back on stimulants like caffeine and alcohol
• Use saunas or hot baths - gentle heat may support NAD+ production
• Stay connected with friends, family, or a support group

Supplementation as an Extra Boost

Alongside healthy lifestyle changes, many people choose to support their NAD+ levels with supplements. NAD+ injections and IV therapy are popular because they deliver NAD+ directly into the bloodstream, offering fast and effective results.

These options can support your health, especially during times of stress, tiredness, or recovery. Combining lifestyle improvements with supplementation may provide a more complete approach to feeling better and staying energised long term.

What Is a NAD+ Supplement?

A NAD+ supplement helps restore levels of Nicotinamide Adenine Dinucleotide (NAD+), a vital molecule found in every cell. As we get older, our NAD+ levels naturally drop. This can affect energy, brain function, metabolism, and the body’s ability to repair itself.

NAD+ supplements are designed to top up these levels. They’re available as oral capsules, precursors like NMN or NR, patches, IV drips, or injections. Of these, NAD+ injections are among the most effective, as they go straight into the bloodstream for quick absorption and high bioavailability.

As with any supplement, how well it works can depend on your age, health, and lifestyle.

It’s important to use NAD+ injections safely to get the best results and avoid side effects. The NAD+ injection pen is made for easy self-use at home. Here’s a simple guide on how to set up, inject, and store your NAD+ safely and effectively.

Self-Injecting at Home: What You Need to Know

The NAD+ pen delivers the solution just under the skin (a subcutaneous injection). Each dose is easy to give yourself by following a few simple steps. For the best results and safety:

• Inject once a day for the first three days (this is your loading phase)
• After that, inject every other day if needed
• Recommended dose: up to 50mg per injection, which is 30 units on the pen (0.3ml)

How to Set Up Your NAD+ Injection Pen

Before you start, let the pen and cartridge sit at room temperature for 2–3 minutes. Then follow these simple steps:

1. Take the pen and cartridge out of their packaging
2. Remove the lid from the pen and unscrew the cartridge holder
3. If you see the plunger, gently push it into the base of the pen
4. Place the NAD+ cartridge into the cartridge holder
5. Screw the cartridge holder back onto the pen
6. Twist the pen until the dosage meter is fully visible
7. Push the dosage meter several times until the plunger reaches the bottom of the cartridge and you feel resistance

Your pen is now ready to use.

How to Give Yourself the Injection

Follow these steps to safely and effectively use your NAD+ injection pen:

1. Attach a 6mm needle to the pen. Leave the needle cover on for now.
2. Clean your chosen injection site (stomach, thigh, or buttock) with an alcohol wipe.
3. Remove the needle cover.
4. Twist the dosage meter to select your dose (e.g. 30 units = 50mg).
5. Gently pinch the skin to pull it away from the muscle.
6. Insert the needle just under the skin and keep your hand steady to avoid bruising.
7. Press the button to deliver the dose.
8. Count to three, then remove the needle.
9. Put the cover back on the needle and unscrew it from the pen.
10. Put the pen lid back on and store it in the fridge.
11. Dispose of the used needle in a sharps bin.

Rotate your injection site each time to avoid skin irritation.

Common Reactions and What to Expect

Mild side effects at the injection site are normal and usually nothing to worry about:

• Redness or a small spot of blood where the needle went in
• A drop of NAD+ solution left on the skin after injection
• Light bruising if the needle moves during use

If you notice ongoing or more serious symptoms, stop using the pen and speak to a healthcare professional.

How Often Should You Take NAD+ Injections?

How often you use NAD+ injections depends on your health goals and routine. Here’s a general guide:

• Loading phase: Inject once a day for the first 3 days
• Maintenance phase: Inject every other day, or as needed

Each dose should be no more than 50mg (0.3ml). Always follow the instructions included with your kit.

Best Practices for Storing and Using NAD+

Follow these tips to keep your NAD+ safe and effective:

• Store the full kit in the fridge at 2°C to 8°C
• Let the pen come to room temperature before each use
• Keep the kit away from sunlight, heat, and moisture
• Store safely out of reach of children and pets

Before using a vial, check for any expiry dates, discolouration, or floating particles. Do not use the solution if it looks off.

How to Refill Your NAD+ Pen

1. Remove the pen lid and unscrew the clear section
2. Push the plunger down to reset it
3. Remove the used cartridge and dispose of it in a sharps bin
4. Insert a new NAD+ cartridge into the clear section
5. Reattach the cartridge section to the pen and use as normal

When to Seek Medical Advice

It is highly recommended to consult a healthcare professional before taking NAD+ daily to ensure the appropriate dosage and frequency based on your health needs and goals_[10].

Additionally, while NAD+ injections are generally well tolerated, you should speak to a healthcare professional if you experience:

• Persistent swelling, redness, or pain at the injection site
• Signs of allergy – rash, itching, or breathing difficulty
• Unusual fatigue, headaches, or digestive upset
• Any symptoms that concern you or feel unusual

What's Included in the NAD+ Pen Kit?

Your injection kit includes everything needed for safe home use:

• 1x NAD+ self-injection pen
• 2x NAD+ solution cartridges
• Micro-needles (6mm)
• Antibacterial wipes
• 1x Sharps bin for safe disposal

NAD+ injections are generally well tolerated when used correctly and may offer several wellness benefits. Because NAD+ is a coenzyme already found in the body, supplementing it through injections is considered low risk for most healthy adults. However, as with any supplement, it's important to understand the potential side effects, interactions, and when NAD+ may not be appropriate.

Possible Side Effects and How to Manage Them

Most side effects from NAD+ injections are mild and short-term. They are typically related to the injection process rather than the NAD+ compound itself.

• Redness or swelling: Common at the injection site; usually fades within hours.
• Bruising: May occur if the needle is moved or the same site is reused frequently.
• Stinging or discomfort: Often reduced by letting the solution reach room temperature before injecting.
• Fatigue or flushing: Can occasionally occur after first-time use but generally settles quickly.

How to reduce side effects:

• Clean the injection site with an alcohol wipe before each use
• Rotate between injection sites to avoid skin irritation
• Inject slowly and stay still during administration
• Warm the pen to room temperature before injecting

If symptoms are persistent, unusual, or severe, stop using NAD+ and consult a healthcare professional.

Who Should Avoid NAD+ Injections?

While NAD+ is safe for many people, it may not be suitable in certain circumstances. You should avoid or delay use if you:

• Are pregnant or breastfeeding
• Have an active or recent cancer diagnosis
• Are receiving chemotherapy or immunosuppressive therapy
• Have known allergies to any component in the injection

Does NAD+ Cause Cancer?

There is no clear evidence that NAD+ directly causes cancer. However, NAD+ plays a role in both cellular repair and energy production pathways. This includes glycolysis, which cancer cells use for rapid growth. Some research suggests cancer cells may exploit NAD+ metabolism to support tumour progression.

At the same time, NAD+ is essential for DNA repair and has even been studied as a potential support in cancer treatment _[11]. The relationship between NAD+ and cancer is complex and not fully understood. If you have a history of cancer or are at increased risk, consult a healthcare professional before starting NAD+ supplementation.

Combining NAD+ With Other Wellness Supplements

NAD+ injections can be used alongside other supplements as part of a holistic wellness routine. Common combinations include:

• Vitamin B12: Often paired with NAD+ to support energy and cognitive function
• Magnesium: Helps with muscle recovery and relaxation
• NMN or NR: NAD+ precursors that may support long-term NAD+ levels
• Adaptogens: Such as rhodiola or ashwagandha, for stress resilience

Does NAD+ Interact With Medications?

NAD+ may interact with certain medications or change how the body responds to them. For example:

• Some antidepressants may affect NAD+ availability, potentially making supplementation less effective
• NAD+ may influence insulin sensitivity, which could affect people managing diabetes
• Other anti-ageing supplements may enhance the effects of NAD+, possibly requiring dosage adjustments

If you are taking prescription medication or other supplements, it's best to speak to a healthcare professional before adding NAD+ to your daily routine. This helps ensure there are no unwanted interactions.

Below, UK Meds has answered some of the most common questions that our customers ask us about NAD+ supplementation:

What Does NAD Mean In Medical Terms?

In medical terms, NAD stands for nicotinamide adenine dinucleotide. This is a coenzyme that is present in the human body. It exists in two forms: NAD+ (oxidised) and NADH (reduced), both of which play key roles in processes like energy production, DNA repair and cellular communication. As we age, NAD+ levels naturally decline, contributing to various health issues and age-related diseases.

It is important to note that NAD+ differs from the abbreviation "NAD", commonly used on NHS health records. This stands for "Nothing Abnormal Detected" _[19].

Do NAD+ injections hurt?

The pain associated with NAD+ injections is typically minimal. You may feel a slight pinch or discomfort when the needle is inserted. Allowing the NAD+ solution to reach room temperature before you inject it can help reduce discomfort. Rotating injection sites can also prevent irritation and soreness.

Is NAD the Same as Vitamin B3?

NAD+ is not exactly the same as vitamin B3, but they are closely linked. Your body makes NAD+ from certain forms of vitamin B3. These include nicotinic acid, nicotinamide, and nicotinamide riboside.

These B3 forms help your body maintain healthy NAD+ levels. This is important for energy, cell repair, and many key functions in the body.

Can NAD+ Help with Hair Growth?

Yes, research shows that boosting NAD+ levels, especially through NMN supplements (a form that helps the body make NAD+), may support healthy hair follicles and improve hair growth and thickness.

NAD+ plays a key role in important cell functions like DNA repair, energy production, and managing oxidative stress (damage caused by free radicals).

Can I buy NAD+ Injections online in the UK?

Yes, you can purchase NAD+ injections such as NAD+ injections by Vivere from UK Meds. Always consult your healthcare provider or doctor before taking NAD supplements to ensure they are safe and suitable for your individual needs.

Do I need a prescription?

No, currently NAD+ does not require a prescription to purchase, meaning it is available over the counter. You should still always consult a medical professional before starting any supplements or treatments.

Which NAD+ injections are available at UK Meds?

UK Meds currently offer the NAD+ injection by Vivere. Vivere’s NAD+ pen is the only one made in a trusted UK MHRA-licensed, GMP-certified facility and supplied by an NHS-approved, UKAS-certified partner.
