I FELT IT ON DAY ONE.
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.
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.
