NAD+ is an incredibly powerful anti-ageing compound. Our bodies naturally produce it – but levels decline as we age. Want to learn more about why you want to slow the decline as much as possible? Let’s take a closer look.

What is NAD+?

NAD+ stands for nicotinamide adenine dinucleotide (that’s quite a mouthful, which is why we shorten it to NAD!)

NAD is a co-enzyme that is found in every single cell of your body. It helps to process nutrients and form ATP – energy for our cells.

We cannot live without NAD. If you run out of it, you die because you can’t fuel your tissues & cells. But what NAD actually does is a bit more complicated, particularly when it comes to the prevention of premature ageing.


This is where the science gets a little complex, so bear with me here. The major function of NAD is to support energy production and DNA repair throughout all of the cells in your body. This helps to maintain the wellbeing of every organ, every gland, everything from your skin to your gut and even your metabolism.

But NAD also has some specific actions when it comes to longevity and healthy ageing, including:

  • Delaying cellular senescence (aka zombie cells – more on those right here)

  • Reducing oxidative stress

  • Protecting against age-related diseases and premature ageing

  • Boosting major anti-ageing pathways including sirtuins, mTOR and AMPK (stay tuned for more info about why they are so amazing!)

Because of these benefits, researchers believe that NAD+ is key to improving your healthspan and potentially even your lifespan!

NAD+ as we age

It’s a pity that NAD is such an amazing compound for protecting against ageing – and yet it decreases as we age! Once you’re over 40, NAD levels decline by up to 50% and continue to drop as you age further.

This leads to symptoms including chronic fatigue, decreased brain function, obesity and accelerated ageing. That’s why we want to ensure we maintain our levels, particularly once you hit your 40s!


There are 3 key steps for supporting NAD levels, particularly to prevent the decline caused by ageing.

Step 1 – cut the factors that deplete NAD

You can’t stop yourself from ageing, but there are also lifestyle factors that deplete levels. To address these, make sure you:

  • Eat a wholefood-based diet

  • Reduce your intake of processed & high-sugar foods

  • Prioritise high-quality sleep

  • Moderate your alcohol intake

  • Stick to an exercise regime that is moderate intensity (not high!)

  • Address any underlying causes of inflammation

Step 2 – Increase your intake of NAD precursors

Yes, you can eat foods that support NAD levels naturally. I’ll explore these foods in more detail in a future article, but the main precursor we want plenty of is NR (nicotinamide riboside).

Unfortunately, diet alone is not enough to increase NAD levels, particularly once the age-related decline kicks in.

Step 3 – supplementation

The benefits of an NR-rich diet and a NAD-supportive lifestyle, while useful, are also limited. That’s where supplements can help to bridge the gap, particularly if your levels are already dropping due to age.

NAD supplements and infusions are popular options. But NAD is too big to get through the cell membranes, meaning that it can’t actually boost NAD where it actually matters – in the cells. The way we can get around that is by using a precursor that can enter the cells and convert into NAD.

This is where NR becomes a key player.

NR can increase NAD levels by up to 60% in middle-aged and older adults. So it really is a game-changer when it comes to supporting NAD!

That’s why I’ve formulated my own innovative supplement designed to support healthy ageing – and I’m so excited to share it with you! Learn more about Energy Glow NR here.
