The benefit: NAD+ is a coenzyme your cells rely on to convert nutrients into usable energy. Levels decline with age, which means your cells are working with less fuel to work with as the years go on. NAD3 is clinically shown through human trial to help restore those levels, and it's the only all natural NAD+ Booster® on the market that does more than just boost NAD+.
What it feels like: Less of that heavy, dragging fatigue that coffee doesn't quite fix. The kind of energy that feels like it's coming from inside you, not from a jolt of caffeine you'll pay for later.
The benefit: As cellular energy improves, so does the energy available to your brain, which is one of the most metabolically demanding organs in your body.
What it feels like: Fewer moments of staring at a screen trying to remember what you were doing. Conversations and tasks feel easier to follow. The mental fog lifts a little, and staying on task doesn't take as much effort.
The benefit: NAD3 Extra Strength pairs NAD+ support with a focus matrix built on Dynamine®, Green Coffee Extract, and glucuronolactone, ingredients chosen to support alertness and concentration without the jittery spike of caffeine alone.
What it feels like: You sit down to work and you stay there. No mental drifting every 15 minutes, no urge to check your phone just to break the monotony. Focus that holds through a long meeting or a demanding task list.
The benefit: Because the focus matrix works alongside NAD+ support rather than relying on caffeine alone, the energy curve is steadier. No sharp spike, no hard crash two hours later.
What it feels like: You get through your afternoon without hitting a wall at 3pm. No second or third coffee just to limp to the end of the day. The energy you start the day with is closer to the energy you have at 5pm.
The benefit: NAD+ plays a role in supporting your cells' natural repair processes, which is part of why it's tied so closely to conversations about healthy aging. Because NAD3 is all natural, it works with those repair processes rather than forcing them, unlike synthetic alternatives on the market.
What it feels like: This one is subtler day to day, but it shows up over time. Better recovery after a hard workout. Feeling less run down after a demanding week. A sense that your body is bouncing back the way it used to.
The benefit: NAD+ is directly involved in the metabolic pathways your body uses to process energy from food, and Green Coffee Extract in the focus matrix has been studied for its role in supporting a healthy metabolic rate.
What it feels like: Less of that sluggish, bloated feeling after meals. A body that feels like it's processing what you eat efficiently, instead of holding onto it. Over time, that can mean an easier relationship with weight management, without a stimulant-heavy fat burner doing all the work.
None of these benefits exist in isolation. That's really the point of NAD3 Extra Strength. It's not just a focus supplement and it's not just a longevity supplement. It's built to address both the cellular groundwork and the day to day output, so the benefits compound instead of just adding up.
And unlike most of what's on the market right now, this isn't a story built on hype. NAD3 is the only all natural NAD+ Booster® proven to work through an actual human clinical trial, not a mouse study extrapolated into a marketing claim.
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.

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.
