N-Stac2 Dual Action NAD Support

Sale price$39.98

We designed N-Stac2 to be a complete cellular maintenance strategy, addressing the interconnected challenges of aging. It’s built on a foundation of distinct, complementary actions, designed with the precision you’d expect from a lab, not a marketing department.

Every ingredient is chosen for its specific role in this multi-pathway system:

Fueling Cellular Energy: A full, clinical-strength 1000mg of Nicotinamide Riboside (NR) provides the essential precursor to boost your body's supply of NAD+, the critical coenzyme for ATP energy production and DNA repair.

Renewing the Power Plants: We support mitochondrial health from two angles. Urolithin A supports mitophagy—the body’s natural process for clearing out old, dysfunctional mitochondria. This is complemented by R-Lipoic Acid, a potent antioxidant that functions within the mitochondria to protect them from oxidative stress.

Clearing & Protecting: To further support the cellular environment, we include Quercetin and Luteolin. These powerful flavonoids assist in managing aging cellular waste and provide additional antioxidant defense against daily stressors.

There are no compromises—only a holistic formula where each component performs a vital function. If you are ready to move beyond generic alternatives and invest in a product built on scientific integrity, we invite you to experience the Mediwel Labs difference.

THE COMPLETE 2-IN-1 CELLULAR FORMULA ▶ Why settle for a basic NAD pill? N-Stac2 combines a full 1000mg NAD+ precursor (NR) with a powerful mitochondrial support stack led by Urolithin A and the highly active R-Lipoic Acid. It’s the smarter way to support healthy aging by targeting both cellular energy production and cellular cleanup for a truly next-generation longevity supplement.

CLINICAL-STRENGTH 1000MG NAD+ BOOSTER ▶ Don't be fooled by mystery formulas with unverified claims. N-Stac2 provides a full, third-party tested 1000mg serving of Nicotinamide Riboside to effectively boost NAD+ levels, supporting cognitive function, metabolism, and DNA repair. A powerful sirtuin activator designed to support vital ATP energy production.

ADVANCED CELLULAR RENEWAL & DEFENSE ▶ Go beyond a simple NAD boost. Our formula adds Urolithin A to support mitochondrial cleanup (mitophagy) and Quercetin to help clear out aging cellular waste. This renewal process is then protected by a potent antioxidant shield of R-Lipoic Acid and Luteolin for a truly comprehensive approach to healthy aging.

FORMULATED BY CHEMISTS, NOT MARKETERS ▶ We at Mediwel feel that trust is everything. Our formula was designed by pharmaceutical chemists for maximum purity, safety, and synergy. This professional-grade longevity supplement is formulated for both men and women serious about investing in their long-term health.

UNCOMPROMISING QUALITY & VERIFICATION ▶ Our commitment to your health is absolute. We produce every batch in a GMP-certified, US-based facility and then verify its purity and potency through rigorous independent, third-party lab testing. Fortified with BioPerine® for enhanced absorption, each bottle contains 60 vegetarian capsules for a full 30-day supply.

Your Brain Needs More Than a Quick Boost

As we get older, it is normal to notice small changes.

You walk into a room and forget why.
You reread the same sentence twice.
You feel mentally tired before the day is done.
You want to stay sharp, but you do not want to depend on caffeine just to feel alert.

That is why Cere-NAC was created.

It supports cognitive health from multiple angles, helping nourish the brain with nutrients connected to memory, focus, calm attention, cellular protection, and healthy brain aging.

The Cere-NAC Formula

Every Ingredient Has a Purpose

Your brain needs more than a quick boost. Cere-NAC combines nootropic support, antioxidant defense, calm focus, and cellular energy nutrients in one complete cognitive health formula.

Complete Cognitive Health Support

Many brain supplements focus on one popular ingredient. Cere-NAC takes a more thoughtful approach by bringing together nutrients that support the brain from multiple angles.

From memory and focus to cellular protection and healthy aging, this formula was built for adults who want steady, daily brain support without relying on caffeine or harsh stimulants.

“Cere-NAC is not a stimulant-heavy focus pill. It is a complete brain support formula made with carefully selected nutrients for memory, clarity, calm attention, antioxidant defense, and healthy brain aging.”

Antioxidant Support NAC + Glycine

Helps support antioxidant activity and cellular protection, giving the brain nutritional support against everyday oxidative stress.

Memory + Focus Alpha GPC + Citicoline

Supports healthy brain communication, focus, and memory-related pathways for adults who want clearer, sharper thinking.

Calm Attention L-Theanine

Promotes calm focus without the harsh edge of stimulants, making it ideal for steady mental clarity throughout the day.

Brain Cell Support Phosphatidylserine

Supports memory, attention, and healthy brain cell function as part of a complete cognitive health routine.

Cellular Energy Alpha Lipoic Acid + Acetyl L-Carnitine

Supports cellular energy and healthy aging, helping your brain get support beyond basic memory ingredients.

Daily Brain Function B Vitamins

Help support energy metabolism and normal brain function, rounding out the formula for daily cognitive support.

Why it matters: Cere-NAC is designed for adults 50+ who want more than a basic memory supplement. It brings together nootropic and neuroprotective nutrients to support cognitive health from several directions.

Not All Brain Supplements Are Built the Same

Many popular brain supplements focus on one narrow area of cognitive support. Cere-NAC is designed to support the brain from multiple angles with nootropic nutrients, antioxidant support, and cellular energy support.
