NMN and CoQ10 Combination Reduces Irregular Heartbeats in Study
Share
Research from Tabriz University of Medical Sciences shows the combination of NMN and CoQ10 significantly reduced irregular heartbeats following heart attack in aged rats, whilst neither compound was effective alone.
Published in Advanced Pharmaceutical Bulletin, this study led by Dr. Reza Badalzadeh reveals that combining these two supplements may offer superior cardiovascular protection in ageing hearts compared to single-compound approaches.
Key Findings
- Combined NMN and CoQ10 dramatically reduced irregular heartbeats (arrhythmias) after simulated heart attack in aged rats
- Neither compound was significantly effective alone - only the combination showed strong protective effects
- Multiple cardiovascular markers improved including heart contraction, blood pumping efficiency, and cellular stress indicators
- The worst type of irregular heartbeat (ventricular fibrillation) was completely eliminated in some cases with combination treatment
Why This Study Matters
Heart attacks become increasingly dangerous with age. Even when blood flow is restored quickly (reperfusion), the process itself can trigger severe irregular heartbeats that prove fatal. This secondary damage after reperfusion is particularly problematic in older hearts.
The study examined whether NMN and CoQ10 together could protect aged hearts better than either compound alone - a question highly relevant for the growing population of older adults at cardiovascular risk.
Understanding the Heart Attack Recovery Problem
When blood flow is restored after a heart attack (reperfusion), the heart experiences massive stress:
Reactive Oxygen Species (ROS) Surge Within seconds of blood returning, the heart releases harmful molecules called reactive oxygen species. These create oxidative stress that damages heart cells.
Antioxidant Depletion Simultaneously, the molecules that normally protect against this stress (antioxidants) drop to dangerously low levels.
Irregular Heartbeats This imbalance triggers arrhythmias - irregular heartbeats that can range from brief disturbances to life-threatening conditions. In aged hearts, these arrhythmias are more frequent, last longer, and are more severe.
The Challenge Successfully treating a heart attack requires not just restoring blood flow, but protecting the heart from the damage that restoration causes. This becomes harder with age as the heart's natural protective mechanisms weaken.
Why NMN and CoQ10?
The researchers chose these specific compounds for clear reasons:
Both Decline with Age Levels of both NMN and CoQ10 drop significantly as we age and drop further during heart attacks. This depletion contributes to mitochondrial damage and oxidative stress.
Complementary Mechanisms
- NMN boosts NAD+ production and enhances the body's antioxidant defences
- CoQ10 (in its ubiquinol form) protects mitochondrial function and reduces ROS production
Targeting Different Stages The researchers used NMN as "preconditioning" (before the injury) and ubiquinol as "postconditioning" (after blood flow returns), targeting both prevention and recovery.
The Study Design
Researchers used aged rats subjected to ischemia-reperfusion injury - a procedure that mimics what happens during a heart attack and subsequent treatment.
Treatment Groups:
- Control (no treatment)
- NMN alone
- Ubiquinol (CoQ10) alone
- NMN + Ubiquinol combination
What They Measured:
- Three types of irregular heartbeats (arrhythmias)
- Heart function markers (contraction strength, blood pumping)
- Cellular damage indicators
- Oxidative stress levels
- Antioxidant enzyme activity
The Results: Combination Wins Decisively
Single Compounds Had Minimal Effect
When used individually, NMN or CoQ10 produced only slight, statistically insignificant improvements in:
- Number of irregular heartbeats
- Duration of arrhythmias
- Cellular damage markers
- Oxidative stress levels
The Combination Was Dramatically Effective
When NMN and CoQ10 were used together, the results transformed:
Arrhythmia Reduction:
- Significantly fewer irregular heartbeats overall
- Shorter duration when they did occur
- Reduced severity across all three types measured
- Complete elimination of ventricular fibrillation (the most dangerous type) in some cases
Heart Function Improvement:
- Better heart contraction strength
- Improved blood pumping efficiency
- Enhanced overall cardiac performance
- Multiple standard heart function measures showed significant improvement
Cellular Protection:
- Substantially lower markers of heart cell damage
- Reduced ROS (harmful oxidative molecules)
- Increased antioxidant enzyme activity
- Improved nitric oxide levels (crucial for heart function)
Why the Combination Works When Single Compounds Don't
The researchers suggest ageing disrupts multiple protective pathways simultaneously. A single intervention can't address all these compromised systems.
Synergistic Protection
NMN and CoQ10 work through different but complementary mechanisms:
- NMN restores NAD+ levels, activating cellular repair and antioxidant systems
- CoQ10 directly protects mitochondria and reduces oxidative stress
- Together, they address multiple aspects of cardiovascular protection simultaneously
Overcoming Age-Related Resistance
Aged hearts appear resistant to single therapies because multiple systems have failed. The combination approach succeeds by supporting several protective pathways at once, compensating for age-related dysfunction.
Practical Applications
For Cardiovascular Health
This research suggests that combining NMN and CoQ10 may offer superior cardiovascular support compared to taking either alone, particularly for:
- Adults over 60
- Those with cardiovascular concerns
- People at higher risk of heart problems
- Anyone seeking comprehensive heart health support
Dosage Considerations
The study used specific doses in rats. Whilst direct translation to humans requires clinical trials, typical human supplementation uses:
- NMN: 250-500mg daily
- CoQ10: 200-300mg daily
Our NMN + CoQ10 Bundle provides both compounds at research-supported doses in a convenient combination.
Timing Matters
The study used NMN before the injury and CoQ10 after, suggesting timing may be relevant. However, for general health maintenance, consistent daily intake of both compounds is the practical approach.
Study Limitations
Animal Model This research used aged rats, not humans. Whilst rat cardiovascular systems share similarities with humans, clinical trials in people are needed to confirm these findings.
Male Subjects Only The study examined only male rats. Sex differences in cardiovascular response are well-documented, so these results may not fully apply to females.
Acute Injury Model The study simulated a single heart attack event. It didn't examine long-term effects or chronic cardiovascular conditions.
Mechanism Unclear Whilst the combination clearly worked, the exact biochemical mechanisms explaining the synergy need further investigation.
What This Means for You
Evidence for Combination Therapy
This study adds to growing evidence that combining cardiovascular-supporting nutrients may be more effective than single compounds, particularly for aged hearts.
Preventive Approach
The research used NMN as preconditioning, suggesting regular supplementation before problems occur may offer protective benefits.
Safe and Accessible
Unlike pharmaceutical interventions, both NMN and CoQ10 are available as dietary supplements with excellent safety profiles.
Not a Treatment
These supplements support cardiovascular health but don't treat heart disease. Anyone with cardiovascular conditions should work with their doctor and follow prescribed treatments.

The Bottom Line
This study provides compelling evidence that combining NMN and CoQ10 offers superior cardiovascular protection in aged hearts compared to either compound alone. Neither supplement showed significant benefits individually, but together they dramatically reduced irregular heartbeats, improved heart function, and protected against cellular damage following simulated heart attack.
For those over 60 or concerned about cardiovascular health, this research suggests combination supplementation may be the smarter approach. The synergistic effects observed in this study support what many longevity researchers have suspected - that multiple-pathway interventions are more effective than single compounds for addressing the complex challenges of cardiovascular ageing.
Whilst human clinical trials are needed to confirm these findings, the safety profiles of both NMN and CoQ10 are well-established, making combination supplementation a reasonable strategy for supporting heart health as we age.
