Why I Stopped Taking NMN? My Personal Journey

Have you heard about the buzz surrounding NMN (Nicotinamide Mononucleotide) supplements? This molecule has taken the health and wellness industry by storm, with claims of anti-aging benefits, improved energy levels, and enhanced cognitive function. Like many others, I was intrigued by the potential of NMN and decided to give it a try. However, after a period of consumption, I made the decision to stop taking NMN. In this blog post, I’ll share my personal experience and the reasons behind my choice.

Key Takeaways

  1. NMN is believed to boost NAD+ levels, which play a crucial role in cellular function and energy production.
  2. While NMN is associated with various benefits, individual experiences may vary, and potential side effects should be considered.
  3. Consulting with a healthcare professional and prioritizing self-care are essential when making decisions about supplementation.

What Is NMN?

Before diving into my personal journey, let’s take a moment to understand what NMN is. NMN is a naturally occurring molecule that serves as a precursor to nicotinamide adenine dinucleotide (NAD+). NAD+ is a coenzyme that plays a vital role in energy metabolism and cellular function.

As we age, NAD+ levels naturally decline, which has been linked to various age-related health issues. NMN supplements aim to boost NAD+ levels, potentially slowing down the aging process and improving overall well-being.

Benefits Of NMN

The popularity of NMN supplements can be attributed to the numerous benefits associated with its consumption. Research suggests that NMN may improve metabolism, enhance cognitive function, and promote cardiovascular health.

Some studies have even indicated that NMN could potentially extend lifespan in animal models. These promising findings have led many individuals, including myself, to explore the potential of NMN supplementation.

Personal Experience With NMN

When I first learned about NMN, I was excited about the possibility of enhancing my overall health and well-being. I began taking NMN supplements daily, following the recommended dosage. Initially, I noticed a slight increase in energy levels and mental clarity.

However, as time passed, I started to question whether these effects were genuinely attributable to NMN or simply a result of my heightened awareness and focus on my health.

Side Effects of NMN

While NMN is generally considered safe, it’s important to acknowledge that individual experiences may vary. Some people have reported side effects such as digestive discomfort, headaches, and sleep disturbances.

In my case, I experienced occasional mild stomach upset and vivid dreams. While these side effects were not severe, they did make me more cautious about the long-term use of NMN.

Reasons for Stopping NMN

After several months of taking NMN, I decided to stop for a few key reasons. Firstly, I realized that the benefits I initially experienced had plateaued, and I was no longer noticing significant improvements in my energy levels or cognitive function.

Secondly, the cost of high-quality NMN supplements was a consideration, as they can be quite expensive in the long run. Finally, I had concerns about the lack of long-term human studies on the safety and efficacy of NMN supplementation. While the available research is promising, I felt that more conclusive evidence was needed before committing to long-term use.

Alternative Options

After stopping NMN, I shifted my focus to alternative ways of supporting my health and well-being. I realized that many of the benefits associated with NMN could be achieved through lifestyle changes and a balanced diet.

Regular exercise, stress management techniques, and consuming a variety of nutrient-dense foods became my primary tools for promoting longevity and optimal health. I also explored other supplements, such as resveratrol and CoQ10, which have been studied for their potential anti-aging properties.

Seeking Professional Advice

It’s crucial to remember that everyone’s health journey is unique, and what works for one person may not work for another. Before starting or stopping any supplement regimen, it’s essential to consult with a healthcare professional or nutritionist.

They can provide personalized advice based on your individual health status, goals, and potential drug interactions. Working closely with a trusted healthcare provider can help you make informed decisions about your supplementation choices.

The Importance of Self-Care

Ultimately, my decision to stop taking NMN was a reminder of the importance of self-care and listening to my body. While the allure of a “miracle supplement” can be tempting, true health and well-being come from a holistic approach that encompasses nutrition, exercise, stress management, and self-awareness. By prioritizing these foundational aspects of health, we can create a strong foundation for longevity and vitality.

If You Stop Taking NMN, What Happens?

Here are a few things that can happen if you stop taking NMN (nicotinamide mononucleotide) supplements:

  1. The anti-aging effects may diminish over time. NMN is thought to increase NAD+ levels which decline with age. NAD+ plays a role in many cellular processes and energy metabolism. Without NMN supplementation, NAD+ levels may start to decrease again.
  2. Some of the benefits like improved energy, exercise endurance, and metabolism may lessen. These benefits are linked to NAD+’s role in energy production.
  3. Cellular repair and regeneration processes may slow down. NAD+ is involved in DNA repair and sirtuin activity which helps regenerate cells.
  4. Neuroprotective effects may decrease. NMN has been shown to protect neurons and improve cognitive function in animal studies. These benefits could revert without steady NMN supplementation.
  5. Cardiovascular benefits like improved blood flow and arterial health may also diminish over time.

It’s possible any anti-aging or health improvements experienced while taking NMN may start to fade without the continued boost in NAD+ levels. 

However, stopping NMN supplementation won’t have an immediately drastic effect. It’s more that the benefits may slowly decrease over time without the extra NAD+ support from NMN.

Any lifestyle factors like diet, exercise, and managing stress can help prolong the benefits too. Talk to your doctor if you are considering stopping NMN, especially if taking it for a specific health condition.

The FDA Ban On NMN

In the year 2015, the Food and Drug Administration (FDA) sent a legal warning to Elysium Health, the company behind marketing NMN. The organization stated in its letter that the company failed to provide scientific evidence supporting NMN supplements’ claimed disease-preventing abilities. Still, plenty of manufacturers sell it, convincing people that it can boost anti-aging properties.

As a result, the FDA banned NMN as a dietary supplement in the United States in December 2022. It’s important to note that the FDA has not verified the supplement’s efficacy or effectiveness yet. According to the FDA’s report, this is merely a precautionary step to investigate NMN’s potential risks and benefits.


In conclusion, my journey with NMN supplementation was a learning experience that highlighted the importance of individual variability and the need for caution when it comes to new supplements. While NMN may offer potential benefits, it’s crucial to weigh the risks and benefits, consult with healthcare professionals, and make informed decisions based on your unique circumstances.

Remember, there is no one-size-fits-all approach to health and wellness. By prioritizing self-care, seeking professional guidance, and adopting a balanced lifestyle, you can optimize your well-being and embrace the journey toward a healthier, more vibrant you.


1. What happens when you stop taking NMN?

Stopping NMN supplementation may result in a gradual decrease in NAD+ levels over time. However, the body can still produce NAD+ naturally through various dietary sources and cellular processes.

2. Are there any side effects of stopping NMN?

There are no known severe side effects associated with stopping NMN supplementation. However, some individuals may experience a slight decrease in energy levels or cognitive function as NAD+ levels return to their baseline.

3. Can I still achieve the benefits of NMN through other means?

Yes, many of the potential benefits associated with NMN can be achieved through a balanced diet, regular exercise, stress management, and other lifestyle factors that support overall health and well-being.

4. Should I consult with a healthcare professional before stopping NMN?

It’s always a good idea to consult with a healthcare professional or nutritionist before making significant changes to your supplement regimen. They can provide personalized advice based on your individual health status and help you make informed decisions.
