By age 50, your NAD+ levels can drop by up to 50%. That loss is linked to slower metabolism, lower energy, brain fog and weaker cellular repair.

Core NAD+ is built to restore what time takes*.

Unlike generic NAD supplements, Core NAD+ is precision-formulated with a unique blend of three clinically researched ingredients:

  • Nicotinamide Riboside (NR): The most bioavailable precursor to NAD+, NR fuels cellular energy and metabolism at the source.

  • Transresveratrol: A natural compound that activates sirtuins—key regulators of aging and mitochondrial function.

  • Vitamin D3: Often overlooked, D3 supports NAD+ metabolism, Bone & Muscle Strength and Immune Resilience.

Together, these ingredients do more than just top up NAD+—they unlock it*.

What you'll feel: Sustained energy, faster recovery, and enhanced resilience—so you stay strong, active, and at your peak*.

Core NAD+™ is for high-achieving adults 50 and older who want to:

  • Reclaim energy without stimulants
  • Stay sharp at work, at home, and in training
  • Support metabolic health and recovery
  • Protect long-term vitality with science—not hype
  • NR (Nicotinamide Riboside): Scientifically backed to replenish NAD+ at the cellular level.
  • Vitamin D: The game-changer in NAD+ metabolism. Most skip it—we don’t. Without Vitamin D, NR conversion is less effective. We include it to maximize absorption, boost resilience and power real results.
  • Transresveratrol: A powerful polyphenol that amplifies NAD+ activity, activating longevity genes and optimizing mitochondrial function.
  • Microcrystalline Cellulose (MCC): No cheap fillers—just pharmaceutical-grade stability. Most brands cut corners with rice flour; we use MCC to ensure purity, enhance bioavailability, and deliver uncompromised potency

As a dietary supplement. Take two (2) capsules daily with 8-12 oz of water.

Core NAD+ works best when taken consistently. Most users experience more energy, clearer focus, and faster recovery within 2–3 weeks.

Pro tip: Stack with Male+ or Female+ for full-spectrum performance—cellular to hormonal.

Ingredient Profile

Nicotinamide Riboside (NR):

As you age, your body produces less NAD+, the fuel your cells need to stay energized. NR helps replenish NAD+ levels, so you wake up feeling refreshed, sharp, and ready to take on the day—whether that’s hitting the golf course, keeping up with grandkids, or traveling the world without dragging.

What You’ll Notice: Improved focus, energy levels and vibrancy.*

Vitamin D:

Strength You Can Rely On. Aging doesn’t have to mean fragility. Vitamin D reinforces bone density, supports muscle function, and strengthens immune resilience, so you stay strong, steady and active for the long haul.

What You’ll Notice: Improved mobility. Faster recovery. Confidence in your strength*.

Transresveratrol:

Defend Your Metabolism. Extend Your Prime. Your body was designed to perform, but oxidative stress, inflammation and metabolic slowdown work against you. Transresveratrol supports healthy cellular function, helping you stay lean, resilient and ready for whatever’s next.

What You’ll Notice: More control over body composition. Better endurance. The ability to push harder, for longer*.

Microcrystalline Cellulose (MCC)

Most supplements use cheap rice fillers—we don’t. MCC is a precision-engineered excipient that enhances ingredient stability, purity, and absorption, so every dose works at peak efficiency. 

What You’ll Notice: Better Absorption,. No Bloating. No Bulk, Consistent Performance – Every capsule delivers exactly what your body needs.

Science-Backed Ingredients

We go beyond standard NAD+ support, combining advanced cofactors, adaptogens, and hormone-supporting nutrients to optimize energy, metabolism, and cellular resilience—tailored to your biology.
