Let me guess how your morning goes, because it's how mine went for three years.
You sleep eight hours and wake up like you didn't. First coffee by 7, second by 9. By 2 PM you hit a wall. By dinner you're running on fumes and snapping at the people you love. So you see your doctor, get the labs, and hear that everything looks "normal," while you're sitting there still exhausted.
"Everything looks normal. You're probably just stressed."
I got tired of being tired. So last fall I turned my kitchen into a little testing lab. Over 10 weeks I tried 5 of the most popular energy supplements on the market: the ones all over Instagram, the ones at Target and GNC, and one $200-a-month "luxury" formula. I spent over $600 of my own money.
I took each one for at least 14 days, with breaks in between, and tracked one simple thing every day: did the afternoon crash show up, or not?
What I learned came down to one thing almost no brand explains, because it makes most of the shelf look like an expensive guess. Here are all 5, ranked worst to best.

How It Works |
Did the Crash Stop? |

PureNADH |

2-3 hrs (that's the caffeine) |
| #5 |
Qunol CoQ10 |
$0.22 |
CoQ10 (heart-focused) |
No change at all |
★ Test Winner
I almost skipped this one. Newer brand, not on Amazon, and the pitch sounded too simple: one capsule, one ingredient. I figured the $200 formula would crush it. I was wrong.
What I liked:
- By day 3 I felt it. By day 5, my 2 PM coffee run just stopped. No jitters, no crash, steady energy still there at 8 PM.
- It's NADH delivered directly: the finished molecule, not a "precursor" your body has to build first. That's why it kicked in fast.
- One capsule a day, 20 minutes before breakfast. No powders, no routine.
- 100-day money-back guarantee, no fine print. That's not how you sell something that doesn't work.
- Vegan, caffeine-free, no fillers, about $1.00/day on subscription.
What I didn't love:
- Direct-to-consumer only. No Amazon, no CVS. You order from their site (mine came in 2 days).
- Newer brand, so fewer online reviews. I trusted their lab certificates instead of a wall of star ratings.
- Only one strength (100 mg), no lower starter dose if you like to ease in.

Why PureNADH Won, and It Wasn't Close
Here's the one thing almost no brand explains: your cells run on a molecule called NADH, also known as Coenzyme 1. It's the spark that turns food into usable energy. Most "energy" products either skip it, or hand you a precursor your body still has to convert.
That reframes the whole ranking. Tru Niagen makes you build NADH through several steps. CoQ10 is a heart supplement. Mushroom coffee is caffeine in a nicer outfit. The $200 formula buries the working ingredient under expensive extras. Only PureNADH gave my cells the finished molecule directly, which is why I felt it by day 3.
On the product side: 100 mg per capsule (most are 10 to 20 mg) and 99.9% verified purity with independent lab certification, rare in a category where most brands won't disclose purity at all.
The best test wasn't even mine. My husband switched off the Tru Niagen he'd taken for a year, and two weeks later said: "Why did I waste a year on the weaker one?"
If your energy keeps crashing every afternoon, this is the one I'd try first. With the 100-day money-back guarantee, the only thing you're really risking is staying tired.

Thank you for this! I've tried 3 of these (Tru Niagen, RYZE and Qunol) and I completely agree. Tru Niagen did basically nothing for me after months of taking it. RYZE is just coffee with extra steps, and Qunol never touched my energy at all. Started PureNADH about 3 weeks ago and for the first time in years I'm not crashing at 2pm. Already reordered.
where do you actually buy PureNADH? is it on amazon or only their website?
You can only get it direct on their site here: purenadh.com/products/purenadh. Took 2 days to arrive for me and the 100-day guarantee applies to every order.
