Are NAD+ supplements the secret to longevity and youthfulness?

The quest for youthfulness and longevity is as old as human history itself. We all yearn for those elusive secrets that promise more vibrant years, hoping to harness the fountain of youth in a bottle, a pill, or a routine.

Recently, there’s been a buzz around a compound named NAD+ and its potential role in the aging process. But what is it exactly?

NAD+, or Nicotinamide Adenine Dinucleotide, is a molecule naturally present in every cell of our bodies. Its primary function? Assisting in the many biochemical reactions that keep us alive and energetic.

Think of NAD+ as one of the backstage crew members in a theater, ensuring the spotlight is right and the curtains rise on cue, though not always in the limelight itself.

Does NAD+ stop aging?

There’s a common saying: “Age is just a number.” While there’s wisdom in that, our bodies might disagree to some extent.

As we age, many natural processes and components within us change, and NAD+ levels are no exception [1]. Before we discuss its decline, let’s first grasp why this molecule is so essential.

Understanding the decline

Age has a subtle way of making changes in our body, doesn’t it? One such change revolves around NAD+, our silent cellular worker bee.

As time goes on, the levels of this crucial molecule start to drop. It’s not an abrupt change but a gradual one that kicks off early, possibly as soon as our 20s or 30s.

Now, why does this happen? Here are a few reasons researchers believe might be behind this decline:

  • Every day, our DNA faces threats—from the sun’s rays to environmental pollutants. Repairing this damage requires NAD+, which can lead to its decrease over time.
  • Some enzymes, like CD38, get busier as we age. They use up more NAD+, causing its levels to drop.
  • Aging cells deal with more stress from inflammation and oxidation. Such stressors can eat into our NAD+ reserves.

The decline in NAD+ isn’t just a quirky fact about aging—it directly affects how we feel and function. From energy levels to cellular repair, this molecule plays a big part in our well-being.

Recognizing its importance and the reasons for its decline gives us a better shot at addressing it head-on. Knowledge, after all, equips us to act.

Reasons for the decline

The age-old question: Why do some things decrease with age? When it comes to the decline of NAD+ levels in our body, the reasons are intriguing, to say the least. While it’s tempting to boil it down to “just aging”, there’s a bit more to the story.

Our DNA takes a beating daily. From harmful sun rays to environmental pollutants, these damages require NAD+ for repair [2]. So, the more the damage, the more NAD+ gets used up.

As we grow older, some enzymes, especially CD38, become more active. These enzymes use NAD+ for their activities. More active enzymes mean less available NAD+.

Over time, our cells deal with increased stress, be it from inflammation or oxidation. Such stress factors can take a toll on our NAD+ stores.

It’s like watching a savings account dwindle over time. The reasons might be multiple – regular expenses, a few unexpected bills, or perhaps less income. Just like that, our NAD+ reserves get impacted due to various factors.

Knowing these reasons is the first step to understanding how we might address or even counteract this decline. 

Effects of the decline

A dip in NAD+ levels isn’t just a matter of numbers on a chart; it translates to tangible effects on our health and well-being. It’s similar to how a car begins to show wear and tear as the miles add up.

So, what happens to us as NAD+ levels decline? Here are some noteworthy effects:

  • NAD+ plays a role in our cellular energy production. As levels decrease, you might feel like someone’s let the air out of your tires—less zippy, more fatigued, and maybe even facing reduced stamina.
  • Memory glitches, occasional brain fog, or trouble focusing? There’s evidence hinting that reduced NAD+ levels could have a role in these cognitive challenges.
  • Youthful skin thrives on cellular repair and regeneration. But, as NAD+ dwindles, our skin might struggle, leading to signs we often associate with aging: wrinkles, dryness, and reduced elasticity.
  • Damaged cells? NAD+ to the rescue! But with decreased levels, this repair process might slacken, making it harder for cells to recover from various stressors.

Imagine running a machine on low fuel; it’s bound to have performance issues. Similarly, as NAD+ levels drop, our body’s performance might shift. Recognizing these effects can empower us to seek solutions and make informed decisions about our health.
