NMN supplements are becoming increasingly popular, especially for men, but many do not understand what they are taking or why they’re even taking it.

We've got you covered if you want to learn the real science behind NMN supplements. Not only will we explain in detail what role this incredible molecule plays inside the body, but we will also cover the many reasons why you should start supplementing with NMN right away.

Once we have covered all of the bases and you have a firm understanding of what NMN is and how it can help you, we will recommend some high-quality NMN supplements that you can add to your daily routine. 

It’s time to get serious and learn the truth behind this popular anti-aging dietary supplement! 

What Are NMN Supplements?

As you may have already heard, NMN supplements are often marketed as daily supplements that can slow down and even reverse aging. While these claims are somewhat exaggerated, there is some compelling evidence that proper NMN supplementation can significantly impact numerous age-related health issues.

To understand what NMN supplements are, it’s vital first to understand what NMN is.

What Is NMN? 

Chemical structure of NMN

Nicotinamide mononucleotide, or NMN for short, is a specific type of molecule that is a derivative of vitamin B3 (niacin). This unique molecule is found in small amounts in many plant-based foods common in most healthy diets, including broccoli, edamame, avocado, cabbage, tomatoes, and more.

According to science, NMN is vital in the human body’s ability to produce a coenzyme called nicotinamide adenine dinucleotide, or NAD+. Once your body has produced NAD+, it plays an essential role in maintaining energy levels and DNA repair.

While the science gets a bit complicated, the main takeaway is that NMN is needed to produce NAD+ efficiently, and NAD+ is needed to maintain healthy energy levels and repair damaged DNA.

Do You Need More NMN As You Get Older?

Unfortunately, NAD+ levels naturally decrease as men age. This process plays a significant role in the entire aging process. Low levels of NAD+ can also contribute to numerous age-related diseases, as healthy levels of NAD+ are essential for repairing damaged DNA.

Since NAD+ levels decline as we get older, it is believed that increased NMN levels can stimulate the production of more NAD+. By boosting NAD+ levels, it is thought that NMN could play a significant role in slowing down age-related physical and mental decline.

Why Supplement With NMN?

You might wonder, “Why can’t I just eat more broccoli if my body needs this NMN stuff and NMN is found in broccoli?”

It’s a valid question, but NMN is only found in minimal amounts in natural food sources. While broccoli is considered one of the best sources of NMN, it only contains 1.33 mg of NMN per 100 grams of broccoli.

Given that NMN supplements tend to have an NMN dosage of 100 mg to 1,000 mg per capsule or pill, you would have to eat a lot of broccoli to get the same amount that you could get through supplementation. Not to mention broccoli or another NMN-rich food would have to be on the menu every single day.

In short, obtaining enough NMN to experience the therapeutic benefits it offers through your diet alone can be challenging. High-quality NMN supplements can deliver an effective dose of this vital molecule simply and reliably.

What Benefits Would NMN Supplements Actually Offer?

By boosting NAD+ levels, it is believed that maintaining healthy levels of NMN can offer the following benefits for men:

Increased Metabolism

Numerous studies have pointed out that supplementation with NMN could increase metabolism and boost energy production. This means that your body can burn calories faster and more efficiently.

Poor metabolism and age-related weight gain are men's most common complaints after age 40, so this could be one of the most important reasons to consider an NMN dietary supplement.

Improved Exercise Performance & Recovery

NMN can boost energy levels, which helps with physical performance, and it has also been shown to reduce muscle damage associated with exercise. This means faster recovery and decreased soreness after exercise.

Improved Cardiovascular Health

Another significant benefit of NMN supplementation is improved blood flow and reduced inflammation throughout the body. This means that it could play a vital role in supporting cardiovascular health.

Improved Cognitive Function and Support for Overall Brain Health

NMN supplementation has been shown to improve cognitive function in numerous studies. Not only does this mean it could potentially help you think clearly, but there is also a belief that it could help prevent and reduce the impact of serious, age-related neurological disorders and diseases like Alzheimer’s disease.

NMN has also been shown to offer numerous other benefits, but the main takeaway is that studies are showing a clear link between NMN supplementation and a variety of health benefits. 

While there is no such thing as an anti-aging pill, the critical role NAD+ plays in cellular health and processes linked to aging could be an essential tool in delaying some of the worst aspects of getting old.
