NAD+ Infusion Therapy: Benefits, Science, and What to Expect in Brisbane

What Is NAD+?

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in every living cell in the human body. It plays a central role in hundreds of metabolic processes, most critically in the production of cellular energy (ATP) within the mitochondria and in the activation of sirtuins — a family of proteins strongly associated with longevity, DNA repair, and cellular stress resistance.

NAD+ levels decline naturally and significantly with age. Research suggests that by the time we reach our 50s, NAD+ levels may be less than half of what they were in our 20s. This decline has been linked to reduced mitochondrial function, impaired DNA repair, increased inflammation, and many of the hallmark features of biological ageing.

The Science Behind NAD+ and Ageing

The relationship between NAD+ and ageing has been one of the most active areas of longevity research over the past decade. Key findings include:

Sirtuin activation: Sirtuins are a family of proteins that regulate cellular health, inflammation, and DNA repair. They require NAD+ as a cofactor to function. When NAD+ levels decline, sirtuin activity decreases, impairing the cell's ability to repair damage and respond to stress.

Mitochondrial function: NAD+ is essential for the electron transport chain — the process by which mitochondria convert nutrients into ATP (cellular energy). Declining NAD+ levels are associated with mitochondrial dysfunction, which manifests as fatigue, cognitive fog, and reduced physical performance.

DNA repair: NAD+ is required by PARP enzymes (poly ADP-ribose polymerases), which detect and repair DNA strand breaks. Impaired DNA repair is a key driver of cellular ageing and cancer risk.

Circadian rhythm regulation: Emerging research suggests that NAD+ plays a role in maintaining healthy circadian rhythms, which govern sleep quality, hormone secretion, and metabolic function.

Why IV Infusion Rather Than Oral Supplements?

NAD+ precursors such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) are available as oral supplements and have demonstrated the ability to raise NAD+ levels in clinical trials. However, IV NAD+ infusion delivers the coenzyme directly into the bloodstream, achieving significantly higher peak plasma concentrations than oral supplementation.

For patients seeking rapid or substantial increases in NAD+ levels — such as those recovering from illness, managing significant fatigue, or pursuing active longevity protocols — IV infusion provides a more direct and efficient route of administration.

What to Expect During a NAD+ Infusion

NAD+ infusions are administered at Australian Longevity Clinic under medical supervision. The infusion is delivered slowly — typically over 2 to 4 hours — as rapid administration can cause temporary side effects including nausea, chest tightness, and a flushing sensation.

Our medical team will determine an appropriate infusion rate based on your individual response. Most patients find that slowing the infusion rate resolves any discomfort quickly. The session is conducted in a comfortable clinical environment, and patients are free to read, work on a laptop, or rest during the infusion.

Common experiences during NAD+ infusion:

• A warm or flushing sensation
• Mild nausea (usually resolved by slowing the infusion rate)
• Increased energy or alertness during or after the infusion
• A sense of mental clarity or improved mood

Reported benefits following a course of NAD+ infusions:

• Improved energy levels and reduced fatigue
• Enhanced mental clarity and cognitive performance
• Better sleep quality
• Improved mood and stress resilience
• Support for addiction recovery programs
• General sense of cellular vitality

Who May Benefit from NAD+ Infusion Therapy?

NAD+ infusion therapy is commonly sought by patients who:

• Experience persistent fatigue or "brain fog" not explained by other conditions
• Are pursuing active longevity and healthy ageing protocols
• Are recovering from prolonged illness or post-viral fatigue
• Are involved in high-performance sport or demanding cognitive work
• Are undergoing addiction recovery support programs
• Are interested in optimising mitochondrial function and cellular health

As with all treatments at Australian Longevity Clinic, NAD+ infusion requires a prior medical consultation to ensure it is appropriate for your individual circumstances.
