Why I Stopped Taking NMN

In recent years, Nicotinamide Mononucleotide (NMN) has surged in popularity as a dietary supplement, hailed for its potential anti-aging and energy-boosting benefits. As someone always on the lookout for ways to enhance my health and well-being, I was naturally drawn to NMN.

My journey began with high hopes, influenced by promising studies and the buzz around NMN’s ability to revitalize energy levels and slow down the aging process.

However, my experience led me to reconsider and ultimately halt my NMN supplementation. This blog delves into the reasons behind my decision, grounded in the latest research and expert insights, to provide a fresh perspective on NMN’s efficacy and safety.

The Promise of NMN

NMN, a precursor to Nicotinamide Adenine Dinucleotide (NAD+), has been touted for its ability to enhance physical function, metabolism, and potentially extend lifespan. The initial allure was undeniable, fueled by studies suggesting that NMN could mimic the effects of diet and exercise by boosting NAD+ levels, thus promoting better health and longevity.

My Experience with NMN

Despite the enthusiasm, my personal experience with NMN did not live up to expectations. While I embarked on this journey hopeful for noticeable improvements in energy and well-being, the results were underwhelming. This discrepancy between expectation and reality prompted me to delve deeper into the latest research to understand the nuances of NMN supplementation.

Research and Expert Opinions

Recent studies provide a mixed picture of NMN’s effectiveness and safety. Clinical trials have generally found NMN to be safe, with no adverse physiological effects reported across various dosages. However, the efficacy of NMN, especially in humans, remains a subject of ongoing research.

A study highlighted by indicated that while NMN is safe up to dosages of 500 mg, showing no significant adverse effects in parameters like gastrointestinal health, heart rate, or blood pressure, its effectiveness, particularly in translating metabolic benefits from animal models to humans, is less conclusive.

For instance, in a small clinical trial focusing on postmenopausal women with prediabetes, NMN supplementation improved insulin muscle sensitivity but failed to replicate other metabolic benefits observed in rodent models​​.

Further exploration into NMN’s impact on vascular health found some benefits for individuals with higher BMI or blood glucose levels, suggesting that NMN could potentially improve vascular health in specific subgroups. Nonetheless, these findings also underline the complexity of NMN’s effects and the need for more comprehensive studies to fully understand its benefits and limitations​​.

Compounding this, recent advancements in NMN human trials have reiterated its safety and highlighted potential benefits such as enhanced insulin sensitivity and physical capacity in older adults. Yet, the full extent of NMN’s anti-aging effects, as demonstrated in rodent studies, has yet to be conclusively proven in humans​​.

Personal Reasons for Discontinuation

As my journey with NMN unfolded, several personal observations and considerations emerged, guiding me to the decision to stop supplementation. My rationale, while unique to my situation, reflects broader concerns and insights that might resonate with others contemplating or currently using NMN.

  • Cost and Accessibility: The financial investment in NMN is non-trivial. Consistent supplementation represents a significant monthly expense, one that I began to question, especially in light of the ambiguous benefits.
  • Questionable Benefits: Despite my hopes, the tangible improvements in energy levels and overall well-being were minimal. This experience aligns with recent studies suggesting that while NMN may offer benefits, they are not universally experienced and can vary widely among individuals​​​​.
  • Side Effects and Health Risks: While I didn’t experience severe side effects, the lack of long-term safety data on NMN use is a concern. The limited scope of human trials and the discrepancy in dosages between these studies and those conducted on animals make it difficult to fully understand the potential risks​​.
  • Philosophical Shift: Over time, my perspective on aging and health intervention evolved. I began to question the wisdom of trying to “out-supplement” the natural aging process, leading me to prioritize lifestyle changes over supplementation.

Alternative Approaches to Health and Longevity

With the decision to stop NMN, I shifted my focus to evidence-based lifestyle interventions known to support health and longevity. This pivot was inspired by a growing body of research underscoring the importance of holistic approaches to wellness.

  • Diet and Nutrition: Emphasizing whole foods, rich in nutrients, antioxidants, and fibers, to support metabolic health and reduce inflammation. Incorporating more plant-based foods and reducing processed food intake can have profound health benefits.
  • Regular Exercise: Engaging in a mix of aerobic, strength, flexibility, and balance exercises to improve cardiovascular health, muscle strength, flexibility, and mental health.
  • Quality Sleep: Prioritizing 7-9 hours of quality sleep per night to enhance cognitive function, mood, and general health.
  • Stress Management: Adopting stress-reduction techniques such as meditation, mindfulness, yoga, or deep breathing exercises to mitigate the adverse effects of stress on the body.
  • Community and Relationships: Investing in social connections and community engagement as a cornerstone of mental and emotional well-being.


In conclusion, my journey with NMN has been illuminating, guiding me through a process of self-discovery and a deeper understanding of the complexities surrounding supplements and health. While NMN holds promise under certain conditions, the decision to stop was the right one for me, based on a careful consideration of the latest research, my personal experience, and a shift towards a more holistic view of health and aging.

This exploration has reaffirmed the importance of grounding health decisions in rigorous scientific evidence, personalized needs, and the understanding that there is no one-size-fits-all solution to wellness. As we navigate the vast landscape of health interventions, let us remain curious, open-minded, and discerning, always prioritizing practices that are safe, effective, and aligned with our individual health goals and values.

Remember, the journey to health and longevity is a personal one, filled with unique challenges and opportunities. May this blog serve as a reminder to approach health supplements with caution, to stay informed through reputable sources, and to always consult healthcare professionals when considering significant changes to your health regimen.
