Musculoskeletal Health and NMN: How NMN Supplementation Could Transform Musculoskeletal Disorders?

Muscle health is vital for our well-being. Recent statistics revealed that over a third of the U.S. population, or 127.4 million people, have disabling musculoskeletal conditions. These disorders ranked third in disease prevalence and were the top contributor to disability in the U.S. Financially, in 2016, they accounted for the highest healthcare spending at $380.9 billion, outpacing both diabetes ($309.1 billion) and cardiovascular disease ($255.1 billion).

Against this backdrop, Nicotinamide Mononucleotide (NMN), as a key molecule in cellular energy metabolism, emerges as a beacon of hope. The scientific community is actively researching NMN's potential to enhance muscle health and combat musculoskeletal ailments.

In this article, we will:

• Examine NMN's connection with muscle health in the context of current health challenges.

• Discuss the potential of NMN supplementation in bolstering muscle strength and health.

• Present the latest research on NMN's role in muscle vitality.

Through this exploration, we aim to spotlight NMN's potential significance in the realm of muscle health. [1] 

What Are Musculoskeletal Disorders?

Musculoskeletal disorders broadly cover conditions affecting the human muscle system, most commonly presenting as skeletal muscle weakness. Terms like 'muscular dystrophy' and 'neuromuscular conditions' are encompassed by the overarching label of 'Muscle Disorders'. 

These disorders either target muscles in our limbs and vital organs or the nerves controlling these muscles. They can be primary, stemming directly from muscle abnormalities, or secondary, resulting from other conditions, like endocrine issues. Their origins vary, from age and heredity to injuries, inflammation, infections, certain medications, and even autoimmune disorders. Sometimes, pinpointing the exact cause is challenging.

Symptoms typically include progressive muscle weakness, breathing challenges, fatigue, numbness, tingling, vision issues, and difficulty walking, among others.

But how does NMN factor into the complex world of musculoskeletal health? Dive deeper with us in the next section, where we unravel the intricate science linking NMN and its potential benefits for muscle health and vitality. Stay with us to uncover more about this groundbreaking research. [2] 

The Intriguing Science of NMN and Musculoskeletal Disorders

As we age, our muscles often weaken, leading researchers to seek ways to counteract this decline. Through various studies, NMN appears to hold the potential in enhancing muscle strength in diverse contexts, from age-related decline to athletic performance. Dive into a review of the latest findings on NMN's capabilities in musculoskeletal health and beyond.

NMN Might Help Improve Muscle Strength in Older Men

A recent study from the University of Tokyo, published in the NPJ Aging in 2022, revealed that NMN supplementation for 12 weeks improved muscle performance in older men by raising their NAD+ levels. 

NMN also potentially enhanced hearing in these participants. The study confirmed NMN's safety, with consistent liver and kidney health indicators.

The men showed improved walking speed, grip strength, and chair-stand ability after taking NMN. While these results are promising, the study's limited scope means more research is needed, especially involving women and exploring higher NMN doses. [3] 

NMN Might Help Treat Muscle Disease Like ALS

In a study published in Science Reports in 2020, ALS, a severe muscle disease, was explored. Those affected by ALS experience rapid muscle strength loss, making breathing difficult and potentially shortening their lifespan. 

While treatments offer limited relief and no cure exists, genetic factors are believed to initiate the disease. Lundt's team studied the role of NAD+, a substance in our bodies, in ALS using mice. 

When these mice had difficulty producing NAD+, their neuromuscular junctions and muscle structures were negatively affected. However, supplementing with NMN, a precursor to NAD+, alleviated many of these issues.

Interestingly, the study indicated people with ALS might have a deficiency in a component vital for NAD+ production, suggesting NMN could be a potential future treatment. [4] 

Another Study Confirms NMN's Potential in Aiding Motor Neurons of ALS-affected Mice

Building on previous findings, a Northwestern University study, also published in Scientific Reports in 2020, reinforced the significance of NMN in treating ALS.

The research identified that in ALS, crucial cellular structures, the mitochondria, are impaired due to decreased NAD+ levels. By supplementing with NMN, the team rejuvenated these malfunctioning mitochondria in ALS mouse models. 

This led to marked improvements, highlighting the potential of NAD+ in combating ALS and possibly other diseases like Alzheimer's. However, the study cautioned against excessive NMN, emphasizing the importance of maintaining NAD+ balance. These insights offer promising avenues for future ALS treatments. [5] 

Washington University Finds a Way to Help Aging Muscles in the Brain

As we age, muscles often weaken, a condition known as sarcopenia, leading to reduced activity and cognitive impacts. Currently, no drugs counteract this muscle aging. 

However, in a study published in Cell Reports in 2022, researchers at Washington University identified a brain transporter, NMN transporter (Slc12a8), linked to muscle energy. Young mice with fewer transporters displayed older muscle behaviors while increasing these transporters in aged mice rejuvenated their muscles. These transporters influence muscle energy utilization. 

Enhancing these transporters could potentially strengthen muscles in the elderly. Preliminary tests with an NMN supplement showed promise in mice and some positive results in humans. More studies are required to confirm NMN's efficacy. If unsuccessful, the focus might shift to amplifying NMN transporters directly. [6] 

NMN Can Help Runners Perform Better

Athletes have always sought ways to enhance performance. Past studies indicated NMN helped mice run longer. 

A study published in the Journal of the International Society of Sports Nutrition in 2021 by researchers from Guangzhou Sport University reveals NMN's positive effects on human runners. 

With NMN supplementation, runners utilized more oxygen, enabling them to run longer without fatigue. Higher NMN doses were more effective, with no adverse effects noted. 

While NMN had previously benefited older individuals, this study showcased its impact on younger, active adults. Combining NMN with training could significantly boost athletic performance, offering runners a promising avenue to elevate their capabilities. [7]
