I don’t know about you, but hitting the big 5-0 completely changed my outlook on health. I started to hear about people my age getting sick, including some friends. For the first time, I actually took my health seriously.

Suddenly, figuring out what keeps me active wasn’t optional – it was a must. And one of the things I stumbled onto was NMN, which can boost NAD+.

Don’t worry, I didn’t know what that was either! Just know that it could mitigate aging-related disorders such as DNA damage and neurodegeneration.

So, what’s NAD+?

So, before diving into NMN, let’s talk about NAD+ and why it’s the star player in the aging game.

Role of NAD+

NAD+ (nicotinamide adenine dinucleotide) is like the ultimate multitasker coenzyme, hanging out in every cell in your body. Imagine NAD+ as the power behind your cell’s operations – a real MVP in a few key areas:

  • Energy Metabolism: This is where NAD+ shines, turning your meals into the energy your cells need to get stuff done. If you’re running low on NAD+, it’s like trying to drive a car on fumes. Energy metabolism isn’t just about staying perky during the day, but about ensuring your health for the long haul.

  • DNA Repair: Life isn’t all sunshine and daisies. Your DNA takes a hit now and then from things like UV rays and pollution. NAD+ is the handyman, fixing up that DNA and keeping your genetic blueprints safe as time marches on.

  • Cell Signaling: NAD+ doesn’t just stop at keeping cells fueled and intact, it helps them talk to each other, too. These chats are essential for keeping processes like metabolism and immune response in tip-top condition, according to the Journal of Translational Medicine.

Decline in NAD+ Levels

But here’s the kicker – NAD+ levels take a nosedive as you get older. By middle age, you’re running on about half the NAD+ you had back in your twenties. This drop can mess with a bunch of stuff:

  • Decreased Energy Production: Fewer NAD+ means your cells are slacking on energy production, leaving you feeling wiped out more often.

  • Impaired DNA Repair: With NAD+ taking a hit, your genetic repair shop’s on a hiring freeze. Damage builds up, paving the way for aging signs and diseases like the Big C.

  • Higher Risk of Age-related Diseases: Less NAD+ is linked to type 2 diabetes, Alzheimer’s, and heart disease. [You can find out more from Health and PMC.

Age GroupNAD+ Levels (Relative)Health Impact
Youth (20-30)100%Top-notch cellular function
Middle Age (50)50%Low energy, sluggish DNA repair
Senior (70+)30%More age-related health issues

Understanding NAD+ and its waning as we get older is key if you’re curious about NMN supplements. Boosting NAD+ levels might just hold the secret to slowing, or even backtracking, some aging hurdles.

This makes NMN a potential standout in your anti-aging toolkit. Curious about more ways to slow the aging clock? See our anti-aging supplements guide.

Benefits of NMN Supplementation

Let’s break down Nicotinamide mononucleotide (NMN) and its flair for amping up NAD+ in our bodies. NAD+ is like a backstage wizard, handling crucial stuff like energy production and fixing up our DNA.

By the time we hit middle age, our NAD+ is down to about half of what it was when we were kids (PubMed). Bringing back those NAD+ levels is like turning up the dial on insulin sensitivity, getting your mitochondria into gear, and adding years – not just to the calendar, but to the good life.

NMN gets to work by cranking up NAD+ production. It nudges enzymes to get the NAD+ machinery running again, blocks CD38 (the little pest that breaks down NAD+), and acts as a prequel to NAD+.

The result? NAD+ levels naturally climb back up (NIH). If you want to go deeper, see my article on how NAD supplements fight aging.

Effects on Physiological Functions

So what’s all the fuss about NMN? Well, it does some pretty cool things to keep our bodies ticking:

  • Adipose Tissue Inflammation: NMN steps up to ease the inflammation in our fat cells that comes with age.

  • Insulin Secretion: It gets those insulin levels up, so we can handle sugar ups and downs much better.

  • Mitochondrial Function: NMN kicks mitochondria into gear, so energy gets pushed out efficiently, lowering the chances of mitochondrial meltdowns.

  • Neuronal Function: Our brain loves NMN – it gives neurons a boost, shielding us from brain fog and other nasties waiting to catch up with us in old age.

Scientific Studies on NMN

I got really curious about NMN supplements and how they could help with healthy aging. The research out there is really interesting, covering both human and animal studies that dive into the possibilities of this supplement.

Human Studies

When it comes to human studies, things are looking pretty good! NMN has shown it can pump up those NAD+ levels, which are really important for keeping our bodies running smoothly.

In one study with 80 healthy middle-aged people, taking NMN daily – either 300 mg, 600 mg, or 900 mg – over 60 days boosted NAD+ in the blood. Those popping 600 mg and 900 mg saw the biggest jumps in their NAD+ counts (Health).

Here’s a quick rundown of the results:

NMN Dose (mg)Duration (days)NAD+ Levels Increase
30060Moderate
60060High
90060Really High

NMN doses as high as 1,200 mg a day seem to bump up insulin sensitivity, help with aerobic performance, and cut down on fatigue – all with little chance of side effects (Healthline). But, there’s still plenty more to learn about the long-term effects of NMN in humans.

Animal Studies

The scoop from animal studies plays a big part in unraveling how NMN could fight aging and beef up our health.

These preclinical studies say NMN might work wonders on age-related issues like type 2 diabetes, weight-related metabolic problems, and brain diseases. Some significant benefits include better blood sugar control, improved insulin response, and keeping the mitochondria (our cells’ powerhouses) in tip-top shape (Journal of Translational Medicine).

Animals have been the focus of much NMN research, especially how it acts across different body systems and disease models:

  • Vascular Health: Boosted blood flow, cut down on stress from oxidation.
  • Cardiac Health: Helped ward off heart failure and improve heart function.
  • Brain Health: Slowed down memory loss and improved cognitive functions.
  • Eye Function: Protected eyesight and slowed down vision issues.

There’s a ton of exciting animal research that shows how NMN could be a major player in slowing aging.

If you’re like me and have passed the 50 mark, NMN might just be worth a shot for leveling up your health game. To see how NMN lines up against other anti-aging options, check out our anti-aging supplements guide.
