Is This Science-Backed Formula The Key to Weight Loss, More Energy AND Better Focus?

Let’s face it: ageing doesn’t send out a memo. One day you’re full of energy and feeling fantastic, but the next? Battles with fatigue, plummeting energy levels, uncontrollable weight gain, and focus so poor you’ll be lucky if you make it to the end of this paragraph. It doesn’t make sense - you’re sleeping well, exercising regularly, and eating healthy. But overall, you’re just feeling a bit rubbish. So, what are you doing wrong?

Absolutely nothing! What’s happening is completely normal. As we enter our 30s, our bodies naturally start to change. How we deal with that change physiologically is unique from person to person, but the root cause is the same: a sudden decline in our NAD+ production. 

What Is NAD+ and What Does it Do?

So what is NAD+? Think of it as your body’s energy currency. The more it has, the more it can spend on your body’s needs. It’s one of the most important molecules you produce and plays a key role in:

  • Supporting healthy ageing
  • Maintaining muscle health and tone
  • Regulating your metabolism
  • Converting food into energy
  • Maintaining focus and concentration
  • Supporting DNA repair
  • Reducing oxidative stress

Your NAD+ levels start to decline rapidly as you age - like a phone battery that doesn’t hold its charge the older it gets. By your 30s, you’ve lost up to 25% of your NAD+ production levels. Dial that up to around 40-50% in your 40s, and after 50? Only 10-30% of youthful NAD+ remains. 

That’s why you start to feel the knock-on effects in your day-to-day life from as early as your 30s. You just may not have realised that your symptoms are all pointing to this. 

The Silent Crisis Inside Your Cells - What Happens When NAD+ Levels Drop

NAD+ fuels nearly every vital process in your body, so when levels drop, the effects can have more of an impact than you realise:


  • Crushing fatigue
  • Stubborn weight gain
  • Muscle loss
  • Slower recovery
  • Brain fog
  • Poor quality sleep


If you’re nodding along to even one of these symptoms, then it’s not “just ageing”, it’s your cells crying out for a refuel of NAD+. Sure, you could just shrug and say “oh well, we all get old”, but there are risks with doing this - especially if you’re only in your thirties. 

  • 30% slower energy production by age 50
  • Losing 8% muscle mass per decade after 40
  • 40% weaker DNA repair by midlife
  • Metabolism slows 2-4% every 10 years

If you can avoid all this, then why wouldn’t you? Ageing might be inevitable, but we can control how we age thanks to the discoveries of modern science, which now offer us an amazing opportunity to live a long, healthy life where we have the energy and mobility to stay active for as long as possible. 

Why Most Anti-Ageing Supplements Fail - And The ONE Promising Solution

Boosting NAD+ production has been all the rage in the celebrity world for some time - with the likes of model Hailey Bieber and the Kardashians swearing by regular NAD+ IV’s as their secret to eternal youth. But with those treatments carrying a hefty price tag, they’re hardly a practical solution for most as a method of defying the ageing process. 

And unfortunately, direct supplementation of NAD+ in tablet or capsule form has shown limited to no effectiveness. Why? Because NAD+ molecules are too large for the body to absorb effectively when given directly. Your digestive system destroys them before they can reach your cells where they’re needed. 

So researchers turned their attention to Nicotinamide Mononucleotide (NMN), a direct precursor to NAD+, and the results have been incredibly promising. When you take NMN, it converts to NAD+ inside your body, and a few landmark studies have shown NMN can:

  • Boost NAD+ levels by up to 90% within weeks
  • Reverse age-related metabolic decline in humans
  • Activate longevity genes that repair DNA

What’s really exciting about this is that it shows NMN isn’t just another supplement trend - it’s a clinically validated way of restoring NAD+ at the cellular level. And because your body converts it as part of its natural processes, the capsule form delivers optimal absorption without the hassle (or eye-watering cost) of IV treatments.

The NAD+ Crash: What Happens When Your Levels Plummet

Without optimal NAD+ levels, your cells operate at a fraction of their potential. Your metabolism falters, workouts feel harder, and sleep lacks depth. Even your most inspired thoughts move through a thick fog. And those luxury skincare products? They rely on NAD+ to work - so without it, you’re paying for results you’ll never fully see.  

NMN is like the raw material that rebuilds NAD+, the critical foundations of your body, which is home to the cells that power everything you do. Look at it this way: Your body knows exactly how to use NAD+ - it’s been part of your blueprint since you were born. But over time, external stressors have weakened the structure. NMN reinforces these original foundations, building them back up again and giving your cells the support to restore themselves to their original strength. 

This isn’t about hiding the cracks with a fresh coat of paint. It’s about rebuilding from the ground up, so your house (body) doesn’t just look incredible, but stands strong from the inside out for decades to come.
