The Tri-Action Formula

Three precise actions.
One complete protocol.

Most supplements pick one. CORE targets all three biological levers simultaneously — because anything less doesn't close the loop.

01 500mg NAD+

Replenish the Fuel

Direct Nicotinamide Adenine Dinucleotide — not a precursor, not NMN, not NR. The actual molecule your mitochondria require to convert food into ATP, in stable dry-capsule form to preserve bioavailability from manufacture to ingestion.

02 150mg Resveratrol

Activate Cellular Repair

An allosteric activator of SIRT1 — the primary 'longevity gene' governing cellular repair, inflammation regulation, and metabolic efficiency. Resveratrol without NAD+ is pressing a gas pedal with no fuel. Together, they run the engine at full capacity.

03 250mg Quercetin

Plug the Leak

A senolytic and specific CD38 inhibitor. CD38 is the enzyme — overexpressed with age and chronic inflammation — that destroys your NAD+ stores faster than any supplement can replenish them. This is the step every single-ingredient product omits entirely.
Why Synergy Matters

The reason NAD+ alone doesn't work for most people over 40

It's not a failure of the molecule. It's a failure of the intervention's design.

⛽
The Fuel
NAD+ is the gasoline. Every cell needs it to convert food into usable energy. Without it, nothing runs.
🔧
The Accelerator
Resveratrol activates the repair machinery. But pressing the accelerator with no fuel accomplishes nothing.
🔩
Plugging the Leak
CD38 punches a hole in the tank. Quercetin seals it. Without this step, every drop of fuel you add drains immediately.

Pouring expensive fuel into a leaking gas tank is the most accurate description of what single-ingredient NAD+ supplementation does for most people over 40. The leak — driven by CD38 overexpression and chronic inflammaging — must be addressed simultaneously. That is what the Tri-Action protocol does.
The Honest Comparison

Why what you've tried before didn't work

Not a failure of the molecule. A failure of the intervention's design.

  • ❌

    Single-ingredient NMN or NR

    Precursor only — no CD38 inhibition, no sirtuin activation. Fuel poured into a leaking tank.

  • ❌

    Amazon 'proprietary blends'

    87% of NR supplements failed independent label testing. 36% contained less than 1% of the stated dose. Often: cacao powder in a capsule.

  • ❌

    Gummy or liquid formats

    High water activity degrades NAD+ precursors before consumption. Stable dry-capsule is non-negotiable.

  • ❌

    Sub-clinical 'fairy dust' doses

    Trace quantities of impressive-sounding ingredients at doses too small to produce any measurable biological effect.

Common Questions

Answered honestly

NMN and NR are precursors — your body has to convert them into NAD+ before they can do anything. CORE delivers direct NAD+ alongside two critical co-factors the precursor-only approach completely ignores: Resveratrol to activate the cellular repair machinery (SIRT1), and Quercetin to inhibit CD38 — the enzyme that destroys your NAD+ stores as fast as most supplements can replenish them. If you felt nothing from NMN or NR, CD38 inhibition is almost certainly the missing piece.
Most customers report a noticeable shift in afternoon cognitive clarity within 7–14 days — the 2pm wall softens or disappears. By weeks 2–3, sleep tends to become more restorative. The full 'saturation point' — where improved energy and clarity become your consistent new baseline — typically occurs around the 90-day mark. That's why we recommend the 3-bottle supply for first-time customers and back it with a 90-day guarantee.
Every batch is independently tested by a certified third-party laboratory and a Certificate of Analysis is available to any customer who emails us. We manufacture domestically in an FDA-registered, cGMP-certified facility. We also publish full ingredient quantities on the label with zero proprietary blends. If you'd like the current COA before purchasing, email us and we'll send it immediately.
We offer a 90-day, no-questions money-back guarantee. Use the full supply. If you don't notice a meaningful difference in cognitive clarity, energy, or recovery capacity, email us for a complete refund. We don't want your money if this doesn't change your baseline.
CORE is generally compatible with most supplements. If you are on prescription medications — particularly blood thinners or immunosuppressants — consult your physician before adding any new supplement. We always recommend discussing any new protocol with a qualified healthcare provider.
You absolutely can start with one bottle. However, the Tri-Action mechanism is cumulative — NAD+ levels build over time, senescent cell clearance via Quercetin is gradual, and SIRT1 activation becomes more pronounced as cellular NAD+ stabilises. The full transformation typically requires the full 90-day protocol. The 3-bottle supply is our honest recommendation. It also saves you 22%.
Subscribe & Save gives you an additional 20% off every order, delivered automatically every 30 days. You can pause, skip, or cancel at any time with zero penalty — no cancellation fee, no minimum commitment, no hoops. Most customers continue because the results make it non-negotiable, not because we've made it difficult to cancel.
The Baseline Is Recoverable

You haven't lost your edge.
You have a biological leak.

The CD38 enzyme is destroying your NAD+ stores faster than any single-ingredient supplement can replenish them. CORE addresses all three dimensions of the problem simultaneously — for the first time.
