The Science of NAD+

NAD+ is one of the most important — and most studied — molecules in human biology. Here’s a plain-English look at what it is, the role it plays inside your cells, and how Avara approaches it.

What is NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell in your body. If DNA is the blueprint, NAD+ is one of the workhorses that keeps the daily machinery of your cells running. It takes part in hundreds of metabolic reactions — most fundamentally, in helping convert the food you eat into the energy your cells use to function.

The role NAD+ plays in the body

NAD+ works as a “helper molecule” for enzymes. Its two best-understood roles are:

• Cellular energy metabolism — NAD+ carries electrons during the process that turns nutrients into ATP, the energy currency of the cell.
• Cellular maintenance & signalling — NAD+ is used by enzyme families such as sirtuins and PARPs, which are involved in DNA repair and the regulation of many cellular processes.

Because it’s used so widely, NAD+ is central to how healthy cells operate.

NAD+ and age

One reason NAD+ has become a major focus of scientific research is a simple observation: NAD+ levels in the body naturally decline as we get older. Researchers around the world are actively studying what that decline means and whether supporting the body’s own NAD+ pathways is worthwhile. It’s a fast-moving, evolving area of science — and one Avara follows closely.

Why precursors — not NAD+ itself

Here’s a common surprise: most “NAD+” supplements don’t actually contain NAD+. The NAD+ molecule is large and unstable, and it’s poorly absorbed when swallowed. Instead, your body builds its own NAD+ from smaller building blocks called precursors. The most researched of these is Nicotinamide Riboside (NR) — a form of vitamin B3 that the body can convert into NAD+. That’s why Avara is built around NR rather than raw NAD+: it’s the approach best supported by current science.

What’s inside Avara

Every Avara formula is fully transparent — the exact amount of each active is printed on the label. Our NAD+ range is built around:

• Nicotinamide Riboside (NR) — a well-studied NAD+ precursor and a form of vitamin B3.
• PQQ (Pyrroloquinoline quinone) — a compound found in foods and studied alongside cellular-energy pathways.
• Trans-Resveratrol — a polyphenol found naturally in grapes and berries.

Our approach

Precision, made daily. We lead with studied, bioavailable actives, dose them at meaningful levels, print the full formulation on every label, and manufacture to strict quality standards. No proprietary blends, nothing hidden — nothing left to guess.

Frequently asked questions

What is NAD+ in simple terms?

NAD+ is a coenzyme your cells use to turn food into energy and to run many everyday cellular processes. It’s present in every cell in the body.

What is nicotinamide riboside (NR)?

NR is a form of vitamin B3 and one of the most researched NAD+ precursors — a building block your body can convert into NAD+.

Is NAD+ the same as NMN?

No. NMN (nicotinamide mononucleotide) and NR are different molecules, but both are NAD+ precursors the body can use to make NAD+.

Does Avara contain actual NAD+?

Like most NAD+ products, Avara is built around the precursor Nicotinamide Riboside, which your body converts into NAD+ — because raw NAD+ is poorly absorbed when taken by mouth.

How do I take it?

Follow the directions on your product’s label. Avara is designed as a simple once-daily routine.
