Curious about NAD+ injections for energy and longevity? Learn what NAD+ does, what to expect, and how to decide if it’s right for your wellness goals.
What is NAD+
NAD+ (short for nicotinamide adenine dinucleotide) is a coenzyme found in all living cells. It’s vital for energy production and cellular metabolism—think of it as fuel for your cells. NAD+ regulates key processes like converting food into cellular energy (ATP), repairing DNA, regulating metabolism, and supporting overall cell function. Unfortunately, NAD+ levels naturally decrease as we age, which can negatively affect our health.
NAD+ plays a vital role in:
- Converting nutrients into energy
- Repairing DNA
- Regulating circadian rhythms
- Activating sirtuins (enzymes linked to longevity)
What Evidence Can Support NAD+
Research indicates that maintaining adequate levels of NAD+ is crucial for cells that require significant energy and for optimal neuronal function. A decline in NAD+ has been linked to several major neurodegenerative conditions, including Alzheimer’s and Parkinson’s diseases, as well as cardiovascular disease and muscle atrophy. In addition, preclinical studies show that restoring NAD+ levels can reverse age-related declines in stem cell function and mitochondrial health in mice.
In humans, the evidence is more preliminary but more than 70 published studies suggest that NAD+ therapies are generally well-tolerated, with typical side effects including nausea, fatigue, headache, or flushing
The Benefits of NAD+
Generally, NAD+ patients report increased energy levels and improved stamina after receiving NAD+ injections, making them appealing for anyone experiencing fatigue or low energy. Enhancing NAD+ levels may:
- Help boost energy
- Support brain health
- Improve mental clarity
- Improve sleep
- Promote healthier skin
- Maintain heart health
- Aid in anti-aging
- Accelerate post-workout recovery
- Improve stress resilience & mood balance
What to Expect During & After NAD+ Injections
At Greenwich Medical Spa, you can expect a seamless treatment process with NAD+ injections taking under 15 minutes—no downtime! Some people feel benefits quickly, while others notice steady improvements over several sessions.
Who is a Good Candidate for NAD+
NAD+ therapy is ideal for anyone who wants to feel more energized, mentally clear, and physically resilient. It is especially beneficial for those on GLP-1 treatments, adults with chronic fatigue, and active individuals seeking faster recovery.
Who Should Not Get NAD+
Individuals with active cancer, severe liver or kidney disease, or those who are pregnant or breastfeeding should generally avoid NAD+ therapy. Because NAD+ promotes cell metabolism and growth, it may pose risks for tumor acceleration or interact with underlying conditions.
Injections are not appropriate for individuals with certain medical conditions, such as:
- Active or untreated cancer
- Uncontrolled cardiovascular disease,
- Low blood pressure
- Arrhythmias
- Liver or kidney disease
- Recent surgery
- Acute illness
