NMN vs NMNH: A Comprehensive Comparison

Written by Valeria Briancesco & Reviewed by Paul Holmes.
Introduction
As interest in health and anti-ageing supplements grows, NMN (Nicotinamide Mononucleotide) and NMNH (Dihydronicotinamide Mononucleotide) have become popular topics of discussion.
Both compounds are linked to boosting NAD+ levels, a crucial factor in cellular energy production and ageing processes. In this article, we explore the differences, benefits, and considerations for these supplements, alongside an introduction to Naturecan’s premium NMN products and complementary longevity solutions.
NMN vs NMNH: What is NMN? A Recap
NMN is a direct precursor to NAD+ (Nicotinamide Adenine Dinucleotide), a molecule that supports energy production and cellular repair. By aiding NAD+ synthesis, NMN may potentially support healthy ageing, improve cellular energy levels, and promote overall cellular function.
NMN also supports metabolic health by improving insulin sensitivity and managing fat accumulation. If you’re unfamiliar with NMN, you can find a detailed overview in our existing article, “What is NMN”. [1]
Definition of NMN
Nicotinamide Mononucleotide (NMN) is a naturally occurring molecule that plays a critical role in boosting NAD+ levels in the body.
NAD+ is vital for energy production, cellular repair, and healthy ageing. NMN is a derivative of vitamin B3, found in small amounts in foods like broccoli, avocados, and milk. Once inside the body, NMN is converted into NAD+, which fuels countless cellular processes.
History of NMN Research
NMN has been the focus of numerous human and animal studies, establishing its safety and potential benefits.
Research on NMN began in the early 2000s, with studies showing its ability to improve energy metabolism and insulin sensitivity in ageing mice. Since then, NMN has been extensively studied in both animals and humans, giving it a strong safety profile.
What is Dihydronicotinamide Mononucleotide (NMNH)?
NMNH, also known as reduced nicotinamide mononucleotide or dihydronicotinamide mononucleotide is a reduced form of NMN, with slight structural differences.
This reduction makes NMNH a potential alternative NAD+ precursor. NMNH may significantly increase cellular NAD+ levels compared to NMN. Preliminary research suggests that NMNH could be more stable or bioavailable in certain conditions, although further studies are needed to substantiate these claims fully. [2]
NMN vs NMNH: Key Differences
Biochemical Differences
NMNH differs from NMN in its reduced molecular structure, which may affect its stability and interaction with enzymes involved in NAD+ synthesis.
NMNH treatment has been shown to influence cellular metabolism, including glycolysis and the TCA cycle.
NMNH inhibited glycolysis, leading to a significant reduction in various glycolytic intermediates while simultaneously affecting TCA cycle intermediates, suggesting a strong inhibitory effect on these metabolic pathways. [3]
Absorption and Efficiency in Cellular Energy Production
Current studies suggest NMN is efficiently absorbed and converted into NAD+. NMNH might enhance cellular energy production more effectively than NMN, leading to significant improvements in metabolic processes, DNA repair, and overall cellular vitality.
NMNH may offer similar or superior absorption rates, but more research is needed to confirm its efficacy. [4]

Potential Benefits for Cellular Health
Both NMN and NMNH are associated with supporting energy production, healthy ageing, and cellular repair. NMNH has been shown to improve mitochondrial function and fat metabolism in brown adipose tissue, playing a significant role in energy metabolism and thermogenesis.
Additionally, NMNH impacts cell growth by inducing reductive stress and suppressing it, leading to cell cycle arrest and inhibiting metabolic pathways like glycolysis and the TCA cycle. While NMN has been more extensively studied, NMNH holds promise as an alternative, potentially offering unique benefits. [5]
NAD+ and Cellular Health
What Is NAD+?
Nicotinamide Adenine Dinucleotide (NAD+) is a coenzyme found in every human cell. It plays a crucial role in energy production, DNA repair, and cellular regulation.
NAD+ levels decline with age, leading to various biological decay and diseases. Supplementing with NAD+ precursors, such as NMN, may be essential for optimal health during age-related decline.

The Role of NMN in Supporting Cellular Health
NMN has been shown to support energy, metabolism, and healthy ageing. It may help improve insulin sensitivity and manage fat accumulation, as well as support heart health by improving blood flow and flexibility in ageing arteries.
Additionally, NMN has been linked to potential improvements in brain function and slower cognitive decline with age. By replenishing NAD+, NMN may also support cellular repair and anti-ageing potential.NMNH, the reduced form of NMN, has been shown to increase NAD+ levels even more rapidly than NMN. However, its safety profile is not as established, and more research is needed to confirm its efficacy and safety.
In conclusion, NMN and NMNH have brought exciting possibilities for supporting cellular health and vitality. While NMN stands out as the more reliable choice due to its extensive research and established safety record, NMNH is still in its infancy in terms of research, making it harder to recommend confidently. As with any supplement, it’s essential to consult a healthcare professional before adding NMN or NMNH to your regimen.

Current Research and Evidence on Age Related Decline
While NMN has been extensively studied, research into NMNH is still in its early stages. NMNH induces reductive stress in cells, leading to cell cycle arrest and suppressed cell growth.
Current evidence highlights the potential of both compounds as NAD+ precursors, but more data is needed to make definitive comparisons. As science progresses, we may gain deeper insights into the specific roles and benefits of each supplement. [7]
