NAD+ therapy explained: What the molecule does and how it's delivered

Introduction: A molecule at the center of cellular metabolism

NAD+ (nicotinamide adenine dinucleotide) is one of the most discussed molecules in aging research, and for a straightforward reason: it participates in a very large number of metabolic reactions in every cell. This article explains what NAD+ does, what the research says about how it changes with age, and how Luvo's program approaches it. It's educational, not medical advice, and not a promise of any result.

What NAD+ does

NAD+ is a coenzyme, a molecule that helps enzymes carry out their work. It's involved in two broad categories of process relevant to aging.

The first is energy metabolism. NAD+ is essential to converting food into cellular energy (ATP) through the mitochondrial electron transport chain.

The second is cellular maintenance and repair. NAD+ is a required input for sirtuins, a family of proteins involved in DNA regulation, inflammation, and cellular stress responses, and it is also consumed by PARP enzymes during DNA repair.

What the research says about NAD+ and age

Studies measuring NAD+ in human tissue have observed that levels tend to change with age. Contributing factors are thought to include greater activity of enzymes that consume NAD+, the ongoing demand of DNA repair, and changes in the body's capacity to synthesize NAD+ from dietary precursors.

How those findings translate to any individual is a separate question. This is an area of active scientific interest, which is also why marketing claims about NAD+ often run ahead of the evidence. The well-established science concerns NAD+'s biological roles.

Precursors, absorption, and product quality

Over-the-counter NAD+ precursors such as NMN and NR are widely sold. Two general points are worth understanding. First, oral precursors must survive digestion, be absorbed, and then be converted through several enzymatic steps, and some is lost at each step, so the amount reaching cells is lower than the label figure. Second, dietary supplements are regulated differently from prescription medications, and independent testing has at times found discrepancies between labeled and actual content.

These are general points about the category, not a claim that any particular product is superior.

How Luvo approaches NAD+

Luvo offers NAD+ through three delivery methods: injection, oral liquid drops, and nasal spray, each with a different absorption profile. Which method, dose, and frequency is appropriate is determined by a licensed provider based on your health history and goals, as part of a clinician-guided program rather than a one-size-fits-all product.
