NAD+ Precursor Support
500 mg Nicotinamide Mononucleotide
NMN is a direct precursor used by the body in the production of NAD+.
Each two-capsule serving provides 500 mg—the amount used in several areas of human NMN research.





Support NAD+ Production—and the Pathways That Help Preserve It
N-Stac™ is built around a fundamental principle in NAD+ biology: maintaining NAD+ involves both replenishment and regulation.
Each serving provides 500 mg of high-purity NMN, combined with plant flavonoids selected for their relevance to CD38-related pathways involved in age-associated NAD+ decline.*
Precision manufactured and third-party tested for identity and purity.
Take two capsules daily, preferably in the morning.
The capsules may be taken on an empty stomach. People with sensitive stomachs may prefer taking them with food.
Each bottle contains:
60 capsules
30 servings
30-day supply
Do not exceed the suggested use unless directed by a qualified healthcare professional.

Manufactured in the USA under strict quality standards.
Produced under strict quality-control standards.
Made without artificial colors, fillers, or preservatives.
More NMN Is Not the Whole Story
NAD+ is a coenzyme involved in normal cellular energy production and many essential cellular processes.
NMN provides the body with a precursor it can use to produce NAD+. But NAD+ metabolism involves more than production alone. Enzymes such as CD38 also consume NAD+ as part of normal cellular activity.
Research suggests that CD38 activity may increase with age. This is why N-Stac™ was designed to address the NAD+ equation from more than one direction.
The N-Stac™ Three-Part System
500 mg Nicotinamide Mononucleotide
NMN is a direct precursor used by the body in the production of NAD+.
Each two-capsule serving provides 500 mg—the amount used in several areas of human NMN research.
150 mg Apigenin + 100 mg Quercetin
Apigenin and quercetin are naturally occurring flavonoids studied for their interaction with several cellular pathways.
Apigenin has been investigated for its potential influence on CD38 activity. Quercetin provides complementary flavonoid and antioxidant support.
Together, they create a more complete formulation than NMN alone.
10 mg BioPerine® Black Pepper Extract
BioPerine® is included to support the bioavailability of selected nutrients in the formula.
Instead of simply increasing the NMN dosage, N-Stac brings multiple ingredients together in one carefully measured daily serving.
Every Active Ingredient. Fully Disclosed.
A direct NAD+ precursor that supports normal cellular energy metabolism.
A plant-derived flavonoid studied for its role in cellular signaling and CD38-related pathways.
A flavonoid that provides complementary antioxidant and cellular support.
A standardized black pepper extract included to support ingredient bioavailability.
No proprietary blends. No hidden dosages. No unnecessary extras.
View the Certificate of AnalysisWhy N-Stac™ Is Different
Many NMN supplements rely on a single strategy: provide the body with a large amount of one precursor. N-Stac™ takes a broader approach.

Research-Informed Formulation
NAD+ is continuously produced and consumed in the body.
NMN supports the production side of that cycle by acting as an NAD+ precursor. CD38 is one of the enzymes involved in NAD+ consumption.
Research has also explored how naturally occurring flavonoids such as apigenin interact with CD38-related pathways.
This provided the rationale behind the N-Stac™ formula.
Built for Informed Supplement Users
N-Stac™ is for those who prefer a transparent, multi-ingredient approach to daily NAD+ support.

Try N-Stac™ Risk-FreeWe've formulated this NMN supplement 500 mg to provide optimal cellular support, helping you maintain vitality and healthy NAD+ levels as you age.
Nicotinamide mononucleotide, or NMN, is a naturally occurring compound used by the body as a precursor in the production of NAD+.
NAD+ is involved in normal cellular energy metabolism and other essential cellular processes.
BioPerine® is a standardized black pepper extract commonly used in supplements to support the bioavailability of selected nutrients.
N-Stac contains 10 mg per serving.
Quercetin is another plant-derived flavonoid. It provides complementary antioxidant and cellular support within the N-Stac formulation.
N-Stac combines 500 mg of NMN with apigenin, quercetin, and BioPerine®.
The formula was created to support more than precursor supply alone. It also includes flavonoids selected for complementary cellular and CD38-related pathway support.
Each two-capsule serving contains 500 mg of NMN.
N-Stac is patent-pending because it tackles the NAD+ problem from two different angles at the same time. Most supplements only try to fix the supply side by adding more NMN, but that is only half the solution.
Our formula works on two pathways:
By helping your body make more while also protecting what you already have, N-Stac offers a much more effective way to maintain your levels. We also included 10mg of Bioperine to make sure your body can actually absorb these ingredients.
No. N-Stac is made without artificial fillers, colors, or preservatives. The formula is built on natural, plant-based ingredients like NMN, apigenin, and quercetin, along with black pepper extract (Bioperine) to help with absorption.
We use vegan capsules and ensure the entire process is Non-GMO. Everything is produced in a cGMP-certified facility that follows FDA standards. We also have every batch third-party tested for purity, and we are happy to provide the Certificates of Analysis if you'd like to see them. What you see on the label is exactly what you get—no hidden blends or secret additives.
We recommend taking two capsules daily, ideally in the morning on an empty stomach, or with food for those with sensitive stomach. This helps with maximum absorption so you can feel the energy and focus benefits throughout your day.
Yes. Quality is our priority. Every batch of our nmn supplement undergoes rigorous 3rd party laboratory testing to ensure purity
While many users report improved mental clarity and physical energy within the first two weeks, the most significant cellular repairs and metabolic improvements typically occur after 30 to 60 days of consistent use.
N-STAC is shelf-stable at room temperature. However, to maintain maximum potency over long periods, keeping the bottle in a cool, dry place away from direct sunlight is recommended.
Yes. Our supplement is made in USA. Manufactured and quality-tested in a GMP-certified facility to ensure safety, purity, and consistency.
Apigenin is a naturally occurring flavonoid studied for its interaction with a number of cellular pathways, including CD38-related activity.
It is included to complement the NMN component of the formula.
