“Why am I so tired all the time?” If you’ve asked yourself that lately — you’re not alone. And it may not be your lifestyle. It could actually be your cells.

I wish someone had told me sooner. Your body naturally produces less of a crucial molecule called NAD+ as you get older. When you’re in your 40s and 50s, your levels can drop significantly. This change matters more than most of us realize.

NAD+ (Nicotinamide Adenine Dinucleotide — quite the mouthful, right?) is involved in literally thousands of processes in your body. Think of it as your cells’ power supply. Without enough of it, everything just starts to feel… harder.

When I first tried this, I honestly felt pleasantly calm straight away, and my energy lasted longer into the evening. Regular use has increased my productivity at work, and kept me calmer when things don’t go to plan.

Why it matters

What NAD+ actually does inside your body

This isn’t wellness buzzword territory — NAD+ is genuinely foundational to how your body functions. Here’s what it’s quietly doing for you every single day.

• Energy production — it helps convert the food you eat into actual usable energy (ATP) at the cellular level. Less NAD+, less efficient energy.

• Brain and nervous system health — supports mental clarity, focus, and cognitive function. That foggy-head feeling? NAD+ has a role here.

• DNA repair — activates enzymes that literally repair and protect your cells. Think of it as your internal maintenance crew.

• Metabolism — helps your body use energy efficiently, not just make it.

• Healthy aging — as NAD+ declines, so does cellular resilience. Supporting levels as we age is one of the most researched areas in longevity science right now.

What the research says:

Studies published in journals (including Cell Metabolism and Nature Aging) have linked declining NAD+ levels to reduced energy metabolism. They have also connected these levels to cognitive changes and slower cellular repair. These factors are all hallmarks of biological aging. Research on NAD+ precursors shows promising results for supporting healthy mitochondrial function and DNA integrity, particularly as we age.

Why I love LiveGood’s NAD+

Okay, so there are lots of NAD+ supplements out there — but the delivery method genuinely matters. LiveGood’s NAD+ comes in a dissolvable oral strip. It melts on your tongue in seconds. Honestly, this is a game-changer for those of us who hate swallowing pills.

Here’s how it works:

Place one strip under your tongue or in your cheek, let it dissolve, then swallow. That’s genuinely it. No capsules, no powders to mix, no taste to choke down. You can do it at your desk, in the car, wherever your morning takes you.

The idea behind the strip format is efficient absorption. By dissolving directly in your mouth, the active ingredient follows a more direct route into your system. This is more efficient than a capsule that must first survive your digestive tract.

The brand

About LiveGood — because transparency matters

I want to know exactly what I am putting into my body and if it has been properly tested. LiveGood is upfront about their ingredients, uses third-party testing, and — refreshingly — keeps their prices genuinely affordable. This isn’t a “sell your kidney” supplement. It’s quality you can actually sustain.

Quick reminder:

As with any supplement, it’s always a good idea to chat with your GP or healthcare practitioner. Do this before adding something new, especially if you’re on medication or managing a health condition. This is about gently supporting your health, not replacing any treatment.

If you’ve been feeling like your get-up-and-go got-up-and-left, it could be time to explore options. If your brain’s foggier than it used to be, consider giving your cells some of extra love. As you navigate this chapter — NAD+ is genuinely worth looking into.

Your energy starts at the cellular level. And now there’s an easy, science-backed way to support it.

“Support your cells. Support your energy. Support healthy aging — gently and naturally.”
