If you've been researching ways to support your wellbeing and came across NAD+, you're among a growing number of people in the UK exploring this coenzyme. This guide provides factual information about NAD+, helping you make informed decisions about whether it aligns with your wellness goals.
Key Points at a Glance
- NAD+ (nicotinamide adenine dinucleotide) is a naturally occurring coenzyme present in all living cells
- NAD+ levels naturally decline with age, particularly after 30
- Various administration methods exist, including injections, oral supplements, and IV infusions
- Always consult with a qualified healthcare professional before starting any new supplement regimen
- People with certain medical conditions should seek medical advice before using NAD+ products
What is NAD+?
NAD+ stands for nicotinamide adenine dinucleotide. It's a coenzyme found in every cell of your body, playing a fundamental role in many biological processes. NAD+ acts as a helper molecule, participating in hundreds of metabolic reactions.
Within cells, NAD+ is involved in energy metabolism, where it helps convert the nutrients from food into cellular energy that powers bodily functions. It participates in DNA repair mechanisms that maintain genetic integrity, supports cellular communication processes that coordinate activities throughout the body, and is essential for proper mitochondrial function, which generates the energy cells need to operate.
Research indicates that NAD+ levels decline naturally with age. By midlife, cellular NAD+ concentrations may be significantly lower than in youth. This decline has been observed across various tissues and is considered part of normal ageing.
Understanding Different NAD+ Supplementation Methods
NAD+ Injections
NAD+ injections involve subcutaneous (under the skin) administration of NAD+. This method bypasses the digestive system, which some research suggests may offer different absorption characteristics compared to oral supplementation.
Injections are typically self-administered at home using pre-filled pens or syringes, though some clinics also offer this service with professional supervision.
Oral NAD+ Precursors
Oral supplements typically contain NAD+ precursors rather than NAD+ itself. These include NMN (Nicotinamide Mononucleotide), NR (Nicotinamide Riboside), and Nicotinamide, which is a form of vitamin B3. These compounds are converted into NAD+ within the body through various metabolic pathways. Oral supplements pass through the digestive system, where they undergo metabolic processing before reaching cells throughout the body.
Intravenous (IV) NAD+ Infusions
IV infusions deliver NAD+ directly into the bloodstream through a vein. This method is administered in clinical settings by healthcare professionals and typically takes 1-3 hours per session.
Who Might Consider NAD+ Supplementation?
People explore NAD+ supplementation for various reasons related to general wellbeing. Common motivations include supporting energy levels and reducing feelings of fatigue, particularly for those experiencing age-related changes in vitality. Many are drawn to NAD+ because of growing interest in cellular health and longevity research. Athletes and active individuals often consider NAD+ for supporting recovery from physical activity, while others explore it as part of a broader approach to healthy ageing. Some people are interested in supporting cognitive function and mental clarity as they age.
However, NAD+ supplementation isn't suitable for everyone. You should speak with your doctor before using NAD+ products if you are pregnant, breastfeeding, or planning pregnancy. Those with any diagnosed medical conditions, particularly cancer or a history of cancer, should seek medical guidance. If you're taking prescription medications, have a history of allergic reactions, or are under 18 years of age, professional consultation is essential before beginning supplementation.
Important: If you have been diagnosed with cancer or have received cancer treatment within the past three years, you must consult your oncologist before considering NAD+ supplementation.
What Does Research Say About NAD+?
Scientific interest in NAD+ has grown considerably in recent years. Research has explored NAD+'s role in various biological processes. Studies examining cellular ageing have investigated how declining NAD+ levels correlate with age-related changes in tissues and organs. Research into mitochondrial function suggests NAD+ plays an important role in cellular energy production, which is fundamental to virtually all bodily processes.
Scientists have also studied NAD+'s involvement in DNA repair, as it's required for certain enzymes that help maintain DNA integrity and cellular health. Additionally, research into metabolic health has investigated how NAD+ participates in various metabolic processes throughout the body.
It's important to note that much of this research is ongoing, and while promising, many studies have been conducted in laboratory settings or animal models. Human clinical trials continue to explore the effects and optimal uses of NAD+ supplementation.
We recommend reviewing current scientific literature and discussing findings with qualified healthcare professionals when considering NAD+ use.
Using NAD+ Injections: What to Expect
Administration
NAD+ injections are typically administered subcutaneously into areas with sufficient fatty tissue, such as:
- Abdomen (belly area)
- Thigh
- Upper arm
Most people describe the sensation as a brief pinching or mild stinging. Rotating injection sites can help minimise discomfort and prevent tissue irritation.
Typical Usage Patterns
While individual needs vary, many people follow an initial loading phase followed by maintenance dosing. A common approach involves:
- Starting with daily injections for 3 consecutive days
- Transitioning to every-other-day dosing
- Adjusting frequency based on individual goals and response
Note: These are general patterns observed by users. Your healthcare provider can help determine an appropriate regimen for your specific situation.
Storage Requirements
NAD+ products must be stored properly to maintain their stability:
- Keep refrigerated at 2-8°C (36-46°F)
- Protect from light and heat
