What is NAD+? The Complete Beginner’s Guide
NAD+ (nicotinamide adenine dinucleotide) has become one of the most talked-about molecules in the wellness and longevity space. But what exactly is NAD+, and why are so many people interested in it? In this beginner’s guide, we’ll break down the science in plain language, explain where NAD+ fits in human biology, and outline why licensed healthcare providers are exploring therapies that support NAD+ levels.
What is NAD+?
- NAD+ is a coenzyme, meaning it helps enzymes do their jobs.
- Found in every living cell, NAD+ is essential for energy production and cellular repair.
- It plays a role in converting the food we eat into the energy our cells use.
Why NAD+ Matters
- Supports mitochondrial function (the cell’s “powerhouse”).
- Involved in DNA repair and cell signaling.
- Plays a role in circadian rhythms and healthy aging.
How NAD+ Levels Change With Age
- Research shows that NAD+ levels naturally decline as we get older.
- Lower levels have been associated with fatigue, slower recovery, and age-related conditions.
Ways to Support NAD+
- Lifestyle: exercise, quality sleep, balanced diet.
- Supplements: precursors like nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN).
- Prescription approaches: therapies such as NAD+ nasal sprays or IV infusions, when prescribed by licensed providers.
NAD+ Therapies: Nasal Spray vs IV
- Nasal sprays: convenient, needle-free, can be self-administered at home if prescribed.
- IV: direct delivery into the bloodstream, often done in a clinic.
- Which option is appropriate depends on individual health needs, determined during a medical consultation.
Key Takeaway
NAD+ is central to energy and healthy aging. While over-the-counter supplements exist, prescription-based therapies like NAD+ nasal sprays may be considered by licensed healthcare providers if clinically appropriate.
