About Nicotinamide Riboside (NR)

Nicotinamide Riboside (NR) is a naturally occurring form of vitamin B3 that supports the body’s ability to maintain healthy levels of NAD⁺ (nicotinamide adenine dinucleotide), a molecule found in every living cell and essential for normal cellular energy production.

NR follows a natural metabolic pathway already present in humans and has been widely studied as a nutritional precursor to NAD⁺.

NR is not foreign to the human diet. It occurs naturally in small amounts in commonly consumed foods, including:

• Milk and dairy products
• Brewer’s yeast
• Whole grains
• Meat, poultry, and fish
• Certain vegetables

These foods typically contain NR in very small quantities, measured in micrograms rather than milligrams.

From diet alone, daily NR intake is generally very low and highly variable. While this background exposure is normal, it is not consistent or sufficient to meaningfully support NAD⁺ levels as we age.

Supplemental NR provides a reliable and consistent intake of the same molecule the body already encounters, without changing how the body regulates NAD⁺ production.

It’s reasonable to hesitate when comparing microgram amounts from food to milligram amounts in supplements.

The key difference is efficiency, not biology.

NR supplementation does not force the body to produce NAD⁺. It simply provides more of a precursor the body already knows how to use and regulate through existing metabolic controls.

NADURA Core provides 300 mg of NR per daily serving, a level intentionally selected to support daily, long-term use without unnecessary excess or complexity.

NAD⁺ plays a central role in cellular energy production by supporting biochemical reactions that allow cells to convert nutrients into usable energy.

By helping maintain NAD⁺ availability, NR supports the body’s normal energy-producing processes at the cellular level, contributing to overall cellular function and vitality.

NAD⁺ is also involved in cellular maintenance processes, including pathways related to DNA integrity and repair.

Adequate NAD⁺ availability supports the activity of enzymes involved in maintaining cellular stability over time. NR contributes to this system by serving as a building block the body can use to replenish NAD⁺ as part of normal cellular turnover.

NAD⁺ is closely tied to metabolic processes that influence how cells manage energy balance and respond to changing demands.

By supporting NAD⁺ biology, NR plays a role in metabolic pathways associated with energy utilization and cellular efficiency, making it relevant for individuals seeking foundational metabolic support.

Nicotinamide Riboside (NR) has been the subject of a growing body of preclinical and human research examining its role in supporting NAD⁺ biology. These studies have explored NR’s effects on NAD⁺ levels, metabolic markers, and core aspects of cellular function.

Human clinical studies have shown that oral NR supplementation can increase blood NAD⁺ levels, with observed increases corresponding to the amount consumed. These findings support NR’s role as a bioavailable NAD⁺ precursor when taken as a dietary supplement.

Ongoing research continues to investigate how NR may support broader aspects of health related to NAD⁺ biology, including metabolic function, cellular resilience, and healthy aging, with additional studies underway across multiple areas of interest.

There are several nutrients the body can use to support NAD⁺ production, including niacin and nicotinamide. Each follows a different metabolic pathway and has been used in different contexts over time.

NR provides a direct and efficient pathway to NAD⁺ that aligns well with consistent, daily use. Unlike niacin, NR is not associated with the flushing response commonly seen with certain forms of vitamin B3.

This distinction makes NR well suited for individuals looking for a steady, comfortable approach to supporting NAD⁺ levels over time.

NADURA Core was created for people who want a calm, foundational approach to NAD⁺ support—one that fits naturally into a daily routine and emphasizes consistency over intensity.
