The Science of NAD+ Therapy: A Deep Dive into Cellular Health and Longevity
As we navigate the advancements of regenerative medicine in 2026, one molecule has emerged as the cornerstone of metabolic optimization and cellular longevity: Nicotinamide Adenine Dinucleotide (NAD+). At Richmond Anti-Aging Clinic (RAAC) in Richmond, BC, we approach aesthetic and systemic wellness through a rigorous scientific lens. While many recognize NAD+ as a "wellness trend," its role in human biology is foundational, serving as a critical coenzyme in every living cell.
Learn more about NAD+ Therapy to understand how we integrate this treatment into our holistic longevity protocols. Under the clinical leadership of Dr. Charles Jiang, a CPSBC-registered physician with over 29 years of medical experience, RAAC provides a physician-led environment where science-backed therapies are tailored to individual metabolic profiles.
The Biochemistry of NAD+: Mechanism of Action
To appreciate the efficacy of NAD+ therapy, one must look at the mitochondrial level. NAD+ is a dinucleotide that exists in two states: NAD+ (the oxidized form) and NADH (the reduced form). This redox pair is essential for the electron transport chain, the primary process by which our cells generate adenosine triphosphate (ATP), or cellular energy.
1. Mitochondrial Bioenergetics
NAD+ acts as a primary electron carrier. In the Krebs cycle, it accepts electrons to become NADH, which then donates those electrons to the mitochondrial membrane to drive ATP production. As we age, the NAD+ pool within our cells significantly depletes. This decline leads to mitochondrial dysfunction, often described by researchers as the "power plant" of the cell losing its efficiency. By replenishing these levels through NAD+ therapy, we aim to restore the efficiency of cellular respiration.
2. DNA Repair and PARPs
Beyond energy production, NAD+ is the mandatory substrate for poly-ADP ribose polymerases (PARPs). PARPs are a family of proteins responsible for repairing damaged DNA. When DNA strands break due to oxidative stress or UV exposure, PARPs consume NAD+ to facilitate the repair process. If NAD+ levels are low, DNA damage can accumulate, leading to cellular senescence or dysfunctional aging. Many of our clients in Richmond seek this therapy specifically for its role in maintaining genomic stability.
3. Sirtuin Activation: The Longevity Genes
Sirtuins (SIRT1-SIRT7) are a class of proteins often referred to as "longevity genes." They regulate metabolic health, inflammation, and circadian rhythms. However, sirtuins are NAD+-dependent; they cannot function without an adequate supply of this coenzyme. High levels of NAD+ therapy may help activate SIRT1, which has been shown to improve insulin sensitivity and promote healthy cellular aging.

Clinical Evidence Summary
The shift toward NAD+ therapy is supported by a growing body of peer-reviewed literature. At RAAC, we prioritize evidence-based protocols to ensure patient safety and efficacy.
- Mitochondrial Communication: Sinclair et al., Cell, demonstrated that increasing NAD+ levels can reverse mitochondrial decay and restore biochemical communication between the nucleus and the mitochondria. This study suggested that cellular aging is not a one-way street but a process that can be metabolically influenced.
- Metabolic Health: Yoshino et al., Science, conducted research indicating that NAD+ precursors can enhance muscle insulin sensitivity and metabolic signaling in humans. This is particularly relevant for patients concerned with metabolic syndrome or age-related muscle decline.
- Sirtuin Pathway Activation: Canto et al., Cell Metabolism, explored how NAD+ availability directly controls the activity of SIRT1. Their findings highlighted that boosting NAD+ levels mimics the beneficial effects of caloric restriction, a known longevity intervention, by optimizing energy expenditure and reducing oxidative stress.
Comparison: IV NAD+ vs. Oral Precursors
Patients often ask why they should choose intravenous NAD+ therapy over over-the-counter supplements like NMN or NR. The primary factor is bioavailability and the "bypass" effect.
| Feature | IV NAD+ Therapy (at RAAC) | Oral Precursors (NMN/NR) |
|---|---|---|
| Bioavailability | 100% - Direct systemic access | Variable (30-60% loss via digestion) |
| Mechanism | Delivers intact NAD+ to the bloodstream | Requires enzymatic conversion in the liver |
| Speed of Action | Immediate cellular saturation | Gradual accumulation over weeks |
| Physician Oversight | Supervised by Dr. Charles Jiang (CPSBC) | Unregulated, self-administered |
| Customization | Dosage adjusted to patient tolerance | Fixed retail dosages |
Candidate Evaluation and Clinical Safety
Not every individual is an immediate candidate for NAD+ therapy. At Richmond Anti-Aging Clinic (RAAC), the evaluation process is rigorous. Dr. Charles Jiang, a CPSBC-registered physician, oversees the medical screening to ensure that the therapy aligns with the patient's current health status.
Ideal candidates often include individuals experiencing:
- Chronic fatigue or "brain fog" related to mitochondrial depletion.
- Age-related cognitive decline or metabolic slowing.
- High levels of oxidative stress from lifestyle or environmental factors.
- Athletes looking for optimized recovery and cellular repair.
Contraindications & Limitations: While NAD+ is a naturally occurring molecule, high-dose intravenous administration must be handled with care. We do not recommend this treatment for pregnant or nursing individuals, or those with certain active malignancies, as NAD+ supports all cellular growth. During your initial assessment, we review your full medical history to mitigate risks.

Frequently Asked Questions
How long does an NAD+ therapy session take?
Because NAD+ must be infused slowly to prevent side effects like chest pressure or nausea, a typical session lasts between 2 to 4 hours. We provide a comfortable, private setting where you can work or rest during the procedure.
Is the treatment painful?
There is a minor pinch associated with the IV insertion. During the infusion, some patients may experience a "flushing" sensation, mild abdominal cramping, or a feeling of pressure in the chest if the rate is too fast. Our medical team monitors you throughout the process and adjusts the drip rate to your comfort level.
How many sessions are recommended?
Individual results vary based on your baseline NAD+ levels and health goals. Many clients start with a loading phase of 3-5 sessions, followed by monthly maintenance. Contact us for current pricing and customized package options.
Is NAD+ therapy approved by regulators?
NAD+ is a naturally occurring coenzyme. Our clinic uses ingredients and protocols that comply with Health Canada and FDA standards for compounding and intravenous administration. It is classified as a nutritional supplement/therapeutic agent rather than a drug.
When will I feel the results?
Some patients report increased mental clarity and energy within 24-48 hours of their first session. However, the deep cellular benefits, such as DNA repair and mitochondrial biogenesis, occur over weeks of consistent treatment.
