Remember when you always had another gear?
You could chase down one more ball.
Run one more possession.
Play one more game.
Now, you may notice your energy fading sooner even though mentally, you still want to keep going.
That’s one of the biggest frustrations of getting older:
Your competitive mindset can stay exactly the same while your energy starts falling behind.
NAD3 Extra Strength was designed to support both immediate energy and longer-term cellular health.
Its Extra Strength Matrix includes ingredients selected to support energy and mental performance, including green coffee bean extract providing 100 mg of caffeine, Dynamine®, and glucuronolactone.
The goal isn’t to turn you into a 20-year-old again.
It’s to help you show up with more in the tank when it’s time to play.
Because sometimes the difference between “I’m done” and “one more game” is simply having enough energy left to enjoy it.
You can still play.
That’s not the problem.
The problem is what happens after.
Maybe your legs feel unusually heavy.
Maybe your whole body reminds you about yesterday’s game every time you get out of a chair.
Maybe you start thinking:
“Do I really want to play tonight if I’m going to feel like this tomorrow?”
That’s when getting older starts changing your relationship with the sport you love.
You don’t stop because you stopped enjoying it.
You start playing less because recovery becomes a bigger price to pay.
NAD3 Extra Strength is positioned to support recovery, resilience, cellular energy, and overall physical performance as part of a daily routine.
And that matters because staying active isn’t just about what happens during the game.
It’s about how ready you feel to come back and play again.
Sports aren’t just physical.
They demand focus.
Reaction.
Decision-making.
Timing.
Awareness.
Whether you’re reading a defense, tracking a ball, lining up a shot, or deciding when to make your move, your brain is part of every play.
And when your mental energy starts fading, your game can feel slower even if your skills haven’t disappeared.
NAD3 Extra Strength combines its NAD3 formula with ingredients designed to support energy, focus, and mental clarity.
That makes it especially interesting for active adults who aren’t simply looking for “more caffeine.”
They want to feel present, sharp, and engaged when they play.
Because one of the best parts of sports is getting locked in and forgetting everything else for a while.
There’s nothing wrong with coffee.
But if your solution to feeling older is always:
“I guess I need more caffeine…”
you may be addressing only one small part of the problem.
NAD3 Extra Strength does contain caffeine — 100 mg per serving — but that’s not the entire formula.
It also contains the NAD3® Patent-Pending Formula, built around ingredients HPN uses to support NAD+ and cellular health.
That’s the difference.
Instead of thinking only about:
“How do I get through this game?”
you can also start thinking:
“How do I support the body I want to keep using for the next 10, 20, or 30 years?”
That’s a much bigger conversation.
And for lifelong sports lovers, it’s probably the more important one.
This is where NAD3 Extra Strength becomes different from a typical energy product.
Think about your goals in two parts.
You want to feel:
You want to support:
Most products are built around one side or the other.
You either get something designed to help you feel something immediately…
Or something positioned around long-term health that you may not notice right away.
NAD3 Extra Strength was designed to bridge those two worlds.
The Extra Strength Matrix supports the “feel it now” side.
The NAD3 formula supports the longer-term cellular-health side.
That’s why it makes sense for someone whose real goal is bigger than one good workout.
Your goal is to keep playing.
“Healthy aging” can sound abstract.
Until you connect it to something you love.
Healthy aging might mean:
Still being able to play pickup basketball at 45.
Still playing tennis at 55.
Still getting out on the golf course at 65.
Still hiking.
Still running.
Still coaching.
Still competing.
Still being the parent or grandparent who actually gets in the game instead of watching from the sidelines.
That’s what makes cellular health matter.
Not because anyone expects to stop aging.
But because aging well means keeping more of the life you enjoy.
NAD3 Extra Strength is built around HPN’s NAD3 formula, which the company positions around NAD+ support, cellular energy, mitochondrial health, metabolism, recovery, and healthy aging.
That may sound scientific.
But the real-life reason to care is simple:
You want your body to keep up with your life.
You probably don’t need to dunk like you did at 22.
You don’t need to run your fastest mile ever.
And you don’t need to pretend getting older isn’t real.
You just don’t want age to slowly take away something that still makes you feel alive.
That’s the real reason products like NAD3 Extra Strength are getting attention from active adults.
Because the goal isn’t necessarily to become a better athlete.
It’s to keep being an athlete.
To keep showing up.
To keep competing.
To keep moving.
To keep saying yes when someone asks:
“You playing today?”
Instead of:
“Nah, I’m too sore from last time.”
NAD3 Extra Strength combines two complementary formulas in one daily serving.
Built around ingredients HPN uses to support:
Featuring:
Designed to support:
2 capsules per serving.
30 servings per bottle.
One simple daily routine designed for both the short game and the long game.
The first NAD+ Booster® Supplement you can actually feel working. Built on the same clinically studied formula trusted by 200,000 people, now with added compounds for effects that are immediate, noticeable, and stronger with every dose!
Most NAD+ supplements ask you to take them on faith. NAD3® Extra Strength is different. Built on a clinically studied formula trusted by 200,000 people and now upgraded with compounds that make the effects immediate and noticeable, this is the NAD+ product that actually delivers.
Most NAD+ products are a long game with no short-term payoff. NAD3® Extra Strength gives you both. Feel amazing on day one, and keep getting better from there.
Instant, clean energy from your very first dose.
Sharper focus and mental clarity you will actually notice.
Long-term cellular health backed by 3 human clinical trials.
Short-term results. Long-term results. No tradeoff.
This is not another supplement you add to a pile and forget about. This is the one you notice.
Short term
Within your first few days you will feel a cleaner, more sustained energy without the jitters or crash. Mental clarity sharpens. Focus comes easier. You will sleep better, wake up more rested, and recover faster between workouts. This is what it feels like when your cells are actually fueled.
Long term
Stay consistent and your body will show it. NAD3® Extra Strength supports the kind of deep, cellular health that shows up everywhere over time. Clearer skin and a radiant glow. A faster, more efficient metabolism. Stronger cardiovascular health with clinically demonstrated reductions in LDL and triglycerides. Faster recovery that compounds week after week. Less inflammation, more resilience, and the kind of vitality that makes people ask what you have been doing differently.
The short game and the long game. NAD3® Extra Strength delivers both.
NAD3® Extra Strength combines two powerful complexes in a single serving. The NAD3® Patent-Pending Formula features Wasabia japonica, Theacrine (as TeaCrine®), and Copper Nicotinic Acid, working together to boost your body’s NAD+ status from the inside out. The Extra Strength Matrix adds Glucuronolactone, Green Coffee Bean Extract (providing 100mg of natural caffeine), and Methylliberine (as Dynamine™) for immediate, feelable energy and focus. No proprietary blends hiding behind weak doses. Every ingredient has a reason to be there.
NAD3® is not built on animal studies and hopeful claims. It is built on human data. While most NAD+ products are still waiting on their first published human trial, NAD3® has three. That is the difference between a supplement that might work and one that does.
3 published human clinical trials
The only NAD+ formula clinically shown to boost cellular NAD+ without a precursor
Improved cardiovascular markers, biological aging, and cellular health demonstrated in real people.
Independently tested by BSCG every batch
NSF cGMP certified manufacturing in the USA.
The science is real. The results are real. The only thing left is to feel it yourself.

Your kit comes with everything you’ll need to start your NAD3® Extra Strength journey, plus a few extras on us!
NAD3 Extra Strength was built for ambitious people who treat their body and mind as a system. Better inputs create better outputs. This is the best one you can give yourself.
Most NAD+ supplements ask you to trust them for 90 days. NAD3 Extra Strength was built to be felt on day one and the data agrees.
The only NAD+ formula combining clinically studied NAD3®, Dynamine™ and Green Coffee Bean Extract in a single capsule. Feel the difference from your very first dose.
No jitters, no crash. NAD3® Extra Strength delivers smooth, sustained energy from ingredients your cells actually use.
NAD3® supports your body’s natural repair process at the cellular level, so you wake up feeling like you actually recovered.
I was honestly skeptical. I have tried other NAD+ supplements and never felt anything. With NAD3 Extra Strength I noticed the difference the same day. Cleaner energy, no crash, just on. This is the one I am sticking with.
I have taken a lot of supplements that promised results I never saw. NAD3 Extra Strength is different. Within the first week my focus was sharper and my afternoon energy crashes stopped. Subscribed immediately and telling everyone I know.
I did not realize how much I was running on empty until NAD3 Extra Strength showed me what feeling good actually feels like. More energy, better recovery, clearer skin. I am not going back.
I’m at a screen 10 hours a day and the mental fatigue was killing my output. NAD3 Extra Strength flipped a switch. Clean energy, locked-in focus, no caffeine jitters and no crash at 2pm. I genuinely feel limitless when I’m dialed in now.
Between work and three kids I was running on fumes by noon. NAD3 Extra Strength gave me steady, clean energy that doesn’t disappear by the afternoon. I’m sharper, calmer, and I actually have something left at the end of the day. Total game changer.
I’m 48 and figured the slow mornings were just part of getting older. A few days on NAD3 Extra Strength proved me wrong. The mental clarity came back fast, my energy is steady, and I feel ten years sharper. Wish I’d started sooner.
I was tired of relying on caffeine while dealing with brain fog, breakouts, and aching joints. Since adding NAD3® to my routine, I’ve felt more energized, focused, and supported overall. I’m definitely sticking with it!
I’ve tried other NAD supplements, but NAD3® has been different. Since adding it to my routine, I’ve noticed better energy and overall support. It’s become part of my daily routine.
I started noticing the signs of aging and low energy, so I added NAD3® to my routine. Since taking it every morning, I feel more focused and supported throughout the day. It’s become a daily staple for me.
The only NAD+ formula you’ll actually feel working. No guesswork, no wasted money, no waiting weeks to wonder if it’s doing anything. Just clean, clinically studied ingredients that deliver from day one.
