This Longevity Supplement Made Me a True Believer

Understanding NMN and Its Role in Health

Nicotinamide mononucleotide, or NMN, has gained attention for its potential role in promoting healthy aging. As a precursor to NAD+, a vital coenzyme involved in cellular energy production, DNA repair, and antioxidant defense, NMN is believed to support various bodily functions. While research on NMN is ongoing, many people have started incorporating it into their wellness routines, especially as they age.

For those interested in longevity and performance, NMN supplements are often touted for their ability to boost energy levels, enhance cognitive function, improve metabolic health, and even support skin and hair health. These benefits make NMN an appealing option for individuals looking to maintain vitality as they grow older.

My Personal Experience with NMN

In 2021, I began working with a biomedical sciences company that produced an NMN supplement. At the time, I was skeptical about the effectiveness of supplements, but as I approached my 40s, I felt the need to be proactive about my health. I took two capsules daily for about eleven months, hoping to feel younger. Unfortunately, I didn’t notice any significant changes at the time.

Fast forward to 2025, when I returned to the same company. This time, I decided to take a more scientific approach by keeping a journal to track my results. By the end of March, I had my first noticeable improvements. I lift weights, attend yoga classes, and rock climb regularly, so I’m always sore. However, I began noticing that my recovery times were faster, even when pushing myself harder. My energy levels also increased, which surprised me given my high-energy lifestyle as a mom of four and a freelance writer.

Dr. Sogol Ash, a naturopathic medical doctor and longevity expert, explained that NMN can help increase NAD+ levels, which decline with age. “Many people notice a boost in energy and mental clarity soon after starting,” she said. The benefits often come gradually, and consistency is key. This might explain why my initial experience with NMN wasn’t as impressive.

Additional Benefits and Observations

As the months passed, I noticed other positive changes. A friend commented on my improved appearance, noting that my fine lines seemed less pronounced. I hadn’t changed my skincare routine, so I couldn’t help but wonder if NMN was responsible. Another significant change was related to my eczema, which had been a persistent issue since the pandemic. Despite managing it through diet and lifestyle changes, I still experienced occasional flare-ups. However, in recent weeks, I’ve noticed a marked improvement in my skin’s condition, with fewer instances of itching and scratching.

Dr. Ash mentioned that many of her patients report similar benefits, including better sleep, quicker recovery from stress, and improved resilience. She also noted that NAD+ can help reduce inflammation, which is linked to chronic health concerns and aging.

FDA Regulations and Legal Status

It’s important to note that the FDA has not approved NMN as a dietary supplement. In 2022, the agency ruled that NMN could not be sold as a supplement under current law due to a specific regulatory clause. This decision was not based on safety concerns but rather on the fact that a company had submitted NMN for drug approval before marketing it as a supplement. This triggered a regulation that prevents ingredients being studied as drugs from also being sold as supplements.

However, in late 2024, the Natural Products Association filed a lawsuit against the FDA challenging this interpretation. As a result, the agency paused enforcement of the NMN ban, allowing supplements to be legally sold directly from manufacturers and other retailers, though not on platforms like Amazon.

Final Thoughts

While research on NMN is ongoing, my personal experience has shown that it can offer tangible benefits, from improved energy and recovery to better skin health and reduced eczema symptoms. As with any supplement, it’s essential to consult with a healthcare professional and conduct thorough research before starting. For me, the evidence is in how I look and feel, and I’m excited to see what the future holds.
