I used to be the person who bounced out of bed.

Early morning runs. Full workdays. Still present for my kids at night. I didn't think twice about any of it.

Then somewhere in my late 40s, things started to quietly shift.

Not dramatically. Not all at once. Just this low-level exhaustion that never really went away. I'd wake up after a full eight hours and feel like I hadn't slept at all. By 2pm, I was white-knuckling it through the afternoon. Coffee stopped working the way it used to. I started canceling things I actually wanted to do.

I told myself it was stress. Work. Getting older. Normal stuff.

Then I went in for a routine checkup at 52.

My bloodwork came back mostly fine. But my doctor, who keeps up with the newer metabolic panels, flagged something I'd never heard of. My NAD+ levels. She showed me the reference chart. For a woman my age, the numbers should be in a certain range.

Mine weren't.

"These look more like what I'd expect in someone in their late 60s," she said.

I went home and started reading.

What Is NAD+ and Why Does It Matter?

NAD+ is a molecule your body produces naturally. It's inside every single cell you have. Your cells use it to convert food into energy. It repairs DNA. It regulates how well your mitochondria, the power plants of your cells, actually function.

When NAD+ is high, your cells run efficiently. You feel it. Mental sharpness. Physical energy. That ability to push through a hard afternoon and still be present at dinner.

When NAD+ is low, the opposite happens. Your cells are working harder for less output. Everything feels like more effort than it should.

Here's the part that nobody tells you upfront: NAD+ levels drop sharply as we age. Research shows that by your 50s, your NAD+ levels may be roughly half of what they were in your 20s. By your 60s, lower still.

That steady decline doesn't just make you tired. It's linked to slower recovery, brain fog, disrupted sleep, and the general feeling that your body just isn't running the way it used to.

It's not in your head. There's a measurable, biological reason you feel this way.

What I Tried First

After my appointment, I did what most people do.

More sleep. Better diet. Cut back on alcohol. I was already exercising. I added B vitamins. Tried ashwagandha. Bought a greens powder that smelled like a lawn.

Some of it helped a little. Nothing fixed the core problem.

I started researching NAD+ supplements specifically. Found a lot of options. Most of them were NR, nicotinamide riboside, which your body has to convert before it can actually use as NAD+. That extra conversion step matters more than most brands admit.

Then I came across something called NMN, nicotinamide mononucleotide. It sits one step closer in the pathway to NAD+. Your body converts it faster and more directly.

The research on NMN has been building for years. Studies out of Washington University and Harvard's Sinclair Lab have looked specifically at what happens to energy metabolism, cellular repair, and aging markers when NAD+ precursor levels are restored. The results caught my attention.

But I'd also been burned before by supplements that looked good on paper and did nothing in the bottle. Purity matters. Dosage matters. Most brands either underdose or don't test what's actually in the capsule.

Why I Chose Omre

I found Omre after a lot of searching.

What made me stop and pay attention: every batch is third-party tested. Not just tested by the company, tested by an independent lab. The Certificate of Analysis is posted publicly. You can see exactly what's in the capsule, including whether there are any contaminants.

That's not standard in this industry. Most supplement companies don't do it.

The dose is 500mg of NMN per serving, which is in line with the amounts used in clinical research, not the token doses some brands use to put "NMN" on the label while barely including any.

No unnecessary fillers. No proprietary blends that hide what's actually in there. Just the compound, at a clinically relevant dose, verified by a third party.

That's what I needed to feel like I could actually trust it.

What Happened After Six Weeks

I want to be straight with you here. I didn't wake up transformed overnight. That's not how this works and anyone who tells you otherwise is selling you something.

What I noticed first, around week two, was that the 2pm wall hit softer. I still got tired, but it wasn't that sudden, heavy drop where I could barely keep my eyes open. It was more manageable.

By week four, I was waking up feeling closer to rested. Not every day. But more days than before. My husband noticed I wasn't reaching for a second cup of coffee before noon.

Around the six-week mark, I had a conversation with a colleague that I realized partway through, I was actually present. Sharp. Following the thread. Not just nodding and hoping nobody asked me to repeat anything back.

And one weekend I went on a long walk with my daughter, a few miles through a local trail, and when we got back I wasn't immediately done for the day. We made lunch. I sat in the garden. I actually enjoyed the afternoon.

That sounds small. But it was the thing I'd been missing for years without fully naming it.

The Part That Surprised Me

I came for the energy.

A few months in, I noticed my sleep felt deeper. Not longer necessarily, but more restorative. I stopped waking up at 3am with my mind racing as often. I woke up, more often than before, actually feeling like the sleep had done something.

I also noticed my skin looked a little better. More even. My nails seemed stronger. I wasn't expecting either of those things.

NAD+ plays a role in cellular repair broadly, not just energy production. Some of what I noticed was probably related to that. My body doing routine maintenance more efficiently.

Who This Is Actually For

If you're in your 40s or 50s and you feel like you're just running slower than you used to, not sick, not broken, just operating at 70% when you used to run at 100%, it's worth understanding why.

This isn't about becoming someone who biohacks everything. I'm not that person. I exercise, I sleep, I eat reasonably well. I just wanted to close the gap between how I was feeling and how I knew I could feel.

If you've already tried the basics and they haven't been enough, the issue might be happening at a cellular level that diet and sleep alone can't fix.

That's what NAD+ support is designed to address.

What to Look For If You're Considering This

Not all NMN supplements are equal. A few things worth checking before you buy anything:

Third-party tested, with the Certificate of Analysis publicly available. If a brand won't show you this, don't buy it.

A minimum of 250–500mg NMN per serving. Less than that and you're likely not at a therapeutically relevant dose.

No proprietary blends. You should be able to see exactly what you're taking and how much.

Omre publishes all of this. It's the reason I stuck with them.

I'm not the person who writes about supplements. I'm the person who was exhausted and skeptical and spent months figuring out what was actually happening to my body.

If any part of what I described sounds like your life right now, the tiredness that doesn't make sense, the afternoons you can't push through, the feeling that you're just not running like yourself, it's worth understanding the biology behind it.

You're not just getting older. Something specific is changing. And for the first time in a few years, I feel like I've actually done something about it.
