As people age, the body undergoes numerous physical and psychological changes, affecting daily functioning significantly. For instance, 77% of older adults have two or more chronic diseases, while 15% report a mental health disorder.

Fortunately, there’s a prospective way to turn back the biological clock and reverse the effects of aging on the body, thanks to advances in aging and longevity research.

Animal and ongoing human studies have established the safety and efficiency of NMN supplements in improving age-related declines. They may have positive outcomes for heart, skin, reproductive, and cognitive health.

NMN is an acronym for niacinamide mononucleotide, a precursor for NAD, with multiple bodily functions, including promoting metabolism, DNA repair, and energy production.

Read on to learn five incredible health benefits of NMN supplements.

# 1. NMN Supplement May Increase Longevity

The search for immortality has been documented since time immemorial. While research has not revealed any remedies for immorality, it has revealed ways to prolong life and delay the effects of aging with NMN supplements. Aging reduces NAD levels in the body, with one study showing that NAD levels reduce by half as we age.

NMN supplements replenish NAD levels, supporting crucial body functions and suppressing age-related changes. Also, NAD helps with DNA repair, which may increase longevity. Research is ongoing on NMN’s skin benefits, and it may alleviate age-related skin damage and hyperpigmentation.

Researchers, including influential longevity experts, have called NMN the proverbial ‘fountain of youth.’ Apart from decelerating the biological hallmarks of aging, NMN supplements may lower the disease burden in the older population. No one wants to live longer if they have to contend with a plethora of chronic diseases and reduced life quality.

# 2. NMN Supplements May Have Brain Protective Effects

One of the famous [NMN supplement benefits](https://www.prohealth.com/blogs/control-how-you-age/nmn-the-basics-benefits-and-recent-research) is improving cognitive health. In animal studies, NMN has been found to enhance mental function, though more research is necessary to determine whether the effects apply to humans.

NMN supplements shield brain cells from mitochondrial impairment and oxidative stress. The former is linked to some neurological disorders like Alzheimer’s disease. Almost seven million people aged above 65 have Alzheimer’s disease. In addition, NAD supports critical brain functions, boosting brain health.

Some NMN supplements are touted to boost memory. Users report experiencing greater focus, mental clarity, and faster information processing after taking NMN supplements. NMN prevents cognitive decline by improving neurovascular coupling and reducing oxidative stress.

# 3. NMN Supplements Can Improve Sleep

According to Sleep Foundation, 50-70 million Americans have sleep disorders, hurting their day-to-day activities, health, and longevity. In fact, people with sleep problems are likely to contract obesity, depression, stroke, heart attack, and hypertension.

Also, sleep disorders may compromise life quality, resulting in poor work/school performance, crowded thinking, irritability, and fatigue.

Multiple studies prove that NMN may be a good supplement for improving sleep quality and minimizing sleep disorders. A 2022 Japanese study assessed the impact of NMN on sleep quality, fatigue, and physical performance in seniors. After 12 weeks of taking NMN supplements, participants reported reduced drowsiness and, consequently, greater physical and mental health.

Similarly, according to an article in the American Journal of Translational Medicine, NMS improves sleep quality by inducing sleep fast and lowering the time to fall asleep. In addition, it enhances the magnitude of REM and deep sleep. Any supplement that improves sleep patterns, especially for older adults, can improve their well-being tremendously.

# 4. NMN Supplements Support Cardiovascular Health

Did you know that 121.5 million American adults have cardiovascular disease, with one person succumbing to it every 33 seconds? NMN is a promising supplement for supporting a healthy heart, especially as you age and your risk factor increases. First, it fosters healthy blood pressure closely related to cardiovascular health.

Second, it enhances blood vessel integrity, ensuring seamless blood flow throughout the body. Vascular endothelial cells deteriorate with age, impeding blood flow and hurting heart health. Third, NMN supplements lower oxidative damage from inflammatory molecules accumulating in the blood.

Lastly, taking NMN supplements may shield the heart from damaging events such as low oxygen and blood flow and mitochondrial dysfunction. An article published in the Cell Death Discovery Journal argues that NAD+ deficiency is a leading factor for heart aging, possibly resulting in heart failure.

NMN supplements can be an anti-aging treatment, increasing NAD+ levels and delaying heart aging, thus preventing heart failure.

# 5. NMN Supplements Improve Diabetes Management

The CDC reports that 11.3% of Americans -37.3 million people have diabetes, costing $327 billion in 2017. Intervention in preventing and managing diabetes will enhance patient lives and lower the economic costs and burden. NMN may help in diabetes management by supporting healthy sugar levels.

Diabetes patients often have decreased NAD levels. Taking NMN supplements may increase NAD in the body, insulin sensitivity, and glucose tolerance, all invaluable for managing diabetes. Washington University research in postmenopausal women revealed that their insulin sensitivity improved after ten weeks of NMN supplementation.

In a journal article titled Nicotinamide mononucleotide, a key NAD+ intermediate, treats the pathophysiology of diet- and age-induced diabetes in mice, the author affirms that NMN boosts glucose tolerance in diabetic mice.

The study examined the effects of the NAD precursor, NMN, on mice with overt diabetes, revealing high NAD concentrations and low blood glucose levels in the animals. While this study shows promising effects of NMN on diabetes, more human research is warranted to examine whether the effects translate to human samples.

# Conclusion

While aging is a natural process, it represents the degeneration of tissues, and its effects can be far-reaching, affecting one’s quality of life, from stimulating cognitive decline to affecting the function of various vital organs. Fortunately, NMN supplements can help restore NAD+ levels to reverse aging and stop age-related conditions.

NMN is a power supplement with many neurological, metabolic, and cardiovascular benefits. As per research studies, it can improve cognitive health, diabetes management, and sleep quality. The supplements may be the miracle cure for aging with anti-aging effects.

Nonetheless, since research on NMN is ongoing, consult a healthcare professional before trying the supplement. They will advise on whether the supplement is ideal for your health needs, any preexisting conditions, and potential risks.
