Why I Stopped Taking NMN: A Tale of Resilience and Rejuvenation

Yes, you read that correctly. I recently made the choice to halt my favorite biohacking supplement Nicotinamide Mononucleotide (NMN). It might seem ironic coming from a wellness advocate like me who has constantly preached about the transformative benefits of NMN.

The headlines you’ve likely seen recently are, “FDA considering regulations on NMN”, which have made many of us question our commitment to this supplement. But here’s the kicker – my decision to stop taking NMN doesn’t mean what you think it does. Let’s unravel the mystery together.

5 best biohacking supplements NMN

What is NMN?

For the uninitiated, Nicotinamide Mononucleotide (NMN) is a nucleotide derived from ribose and nicotinamide. It’s critical in the production of NAD+ (Nicotinamide Adenine Dinucleotide), a crucial coenzyme found in every cell of our body. NAD+ is vital for numerous essential biological processes, including energy metabolism, DNA repair, and even the lengthening of telomeres, the protective end caps of our DNA[1].

My NMN Journey

My love of NMN began at the beginning of 2023, when I began hearing more and more about this supplement from the likes of Andrew Huberman and David Sinclair. That’s when NMN came into my life. I read countless studies, like the one from Washington University School of Medicine, stating that NMN can offset the physical decline associated with aging[2]. It was like I had stumbled upon the fountain of youth.

I was skeptical but hopeful. I decided to buy my first bottle from Renue By Science as recommended by Andrew Huberman himself. Once I started taking NMN, I felt a profound difference. The mid-afternoon energy crashes were replaced with consistent vitality throughout the day. My cardio workouts became more intense and longer. My muscles recovered faster from strenuous exercise. I felt, in many ways, rejuvenated. NMN became a catalyst for my wellness journey. I was, undoubtedly, on Team NMN.

FDA Banned NMN

The FDA’s Current Stance

Recently, there have been whispers that the FDA is contemplating regulating NMN, potentially even making it a prescription-only supplement. This news has triggered a tsunami of skepticism amongst many NMN users, and rightly so.

There’s a fear of losing access to a supplement that has transformed many lives, including mine. This announcement was what initially led me to halt my NMN supplementation. However, it also forced me to take a step back and assess my wellness journey holistically.

Why I Stopped…

Let me be real with you. I only stopped this supplement for a total of 2 weeks. And I’ll explain why.

In the wake of the news about potential FDA regulations, I won’t stop taking NMN indefinitely. In fact, I’m going to continue my use and stock up on as much as I can.

The reason I stopped for 2 weeks was to understand the impact it had on my well-being and whether its benefits were as pronounced as I believed them to be. Essentially, I was seeking clarity – clarity about my health, my body’s resilience, and the true impact of NMN.

You might think, given the title of this blog, that my experiment proved NMN’s effects to be exaggerated. Well, you’d be wrong. The opposite happened. Once I stopped, I realized how much of a difference NMN made in my life. My energy levels dropped, my workouts became more strenuous, and I found myself longing for the vitality I’d previously experienced.

Thus, I stand in defiance of the FDA’s potential decision. I’m choosing not to be a sheep that follows the herd but rather a well-informed individual who bases his decisions on personal experiences and comprehensive research.

I encourage you to do the same and consider beginning your NMN supplementation, hopefully, as a testament to those who are questioning whether they should do the same. Our bodies are different, our experiences unique, but NMN has undoubtedly transformed my well-being and I am confident it can do the same for many others.

The Future of NMN

The FDA’s decision is yet to be final, but regardless of the outcome, I’m hopeful for the future of NMN. It’s sparked a dialogue about biohacking and how we can take control of our well-being, and that in itself is a positive outcome.

Should the FDA decide to regulate NMN and make it prescription-only, it’ll be a testament to its effectiveness rather than a reason to abandon it. After all, regulation often means recognition of a substance’s profound impact on health.

I won’t stop taking NMN, and my journey with it is far from over. As a devoted wellness advocate, I will continue to explore and experiment. Our journey to health and longevity is a long one, but with the right tools and mindset, it can be an extraordinary one.

Closing Thoughts

P.S. If you’re thinking about picking up some NMN for yourself, Renue By Science is the brand recommended by Andrew Huberman, and also happens to be extremely affordable at $15/month at the time of writing this. You can use my Renue By Science coupon code “INTELLIGENT” for 10% off any purchase.

AND, before you freak out at the $99 price tag of a tub of the Renue By Science NMN, let’s do some simple math to break down the real monthly cost. The tub contains 200 servings for $99 which would make each serving $0.49. So… 30 servings in a month is $14.85/month.

I can’t tell you how many people come to me saying “It’s $100 a month! No way I’m buying that!”. It’s very important to read labels and break down the real monthly cost yourself. At $14.85 a month BEFORE my discount code, I think most people can afford it. So it’s worth at least trying once.
