NMN & NR Supplementation · 2026-03-11


    Nicotinamide mononucleotide (NMN) supplementation may lead to modest reductions in blood pressure among older adults. High blood pressure is a significant risk factor for cardiovascular diseases, which can impact longevity and healthspan. Recent research has focused on NMN as a potential supplement to improve health outcomes, particularly in aging populations.

 What this study examined

This systematic review and meta-analysis evaluated the effects of NMN supplementation on resting systolic blood pressure (SBP) and diastolic blood pressure (DBP) in adults with elevated blood pressure. The researchers conducted a comprehensive literature search across several databases, including PubMed/MEDLINE, Scopus, Web of Science, and EBSCO, from their inception until December 13, 2025. The analysis included data from 10 randomized controlled trials (RCTs) comprising 349 participants. The primary outcomes were changes in resting SBP and DBP following NMN supplementation compared to placebo.

 Why this matters for longevity research

Understanding the effects of NMN on blood pressure is crucial as hypertension is a modifiable risk factor for cardiovascular diseases, which are leading causes of morbidity and mortality in aging populations. The findings suggest that NMN supplementation could play a role in early-stage blood pressure management, particularly in older adults. This aligns with ongoing research into the biology of aging, where maintaining cardiovascular health is essential for extending healthspan and potentially lifespan.

 Key findings

NMN supplementation was associated with a modest reduction in resting DBP by approximately 2.15 mmHg.

The reduction in resting SBP was not statistically significant overall.

Among participants aged 60 years and older, NMN supplementation resulted in a significant reduction in SBP by about 3.94 mmHg.

A total of 349 participants from 10 RCTs were included in the analysis.

Subgroup analyses were performed based on age, baseline body mass index, geographical location, intervention duration, NMN dosage, and baseline blood pressure.

The study emphasizes the need for long-term, high-quality RCTs to confirm NMN's efficacy in blood pressure management.

Results indicate that NMN could be a viable candidate for early-stage blood pressure management.

 The science behind it

Nicotinamide mononucleotide is a precursor to nicotinamide adenine dinucleotide (NAD+), a critical coenzyme involved in various metabolic processes. NAD+ plays a vital role in cellular energy metabolism and is essential for the activity of sirtuins, which are proteins linked to aging and longevity. By enhancing NAD+ levels, NMN may influence metabolic pathways that regulate blood pressure and vascular health. This relationship underscores the potential of NMN in addressing age-related physiological decline and promoting a healthier lifespan.

 How it fits into the longevity field

The exploration of NMN in blood pressure management contributes to a broader understanding of interventions aimed at extending healthspan. Other compounds, such as resveratrol and various peptides, have also been studied for their effects on aging and cardiovascular health. NMN's role in enhancing NAD+ levels positions it alongside these interventions, offering a multifaceted approach to longevity research. Continued investigation into NMN and related compounds may reveal synergistic effects that enhance overall health outcomes in aging populations.

 Practical takeaways

Researchers and informed readers should consider the implications of NMN supplementation in the context of blood pressure management and cardiovascular health. While the findings are promising, they highlight the necessity for further research to establish NMN's efficacy and safety in long-term use. As the field of longevity research evolves, understanding the mechanisms by which NMN influences health outcomes will be crucial for developing effective interventions.
