THE SCIENCE
The biology of living better, longer.
Aging begins in your cells. Research is finding that we can influence that.
THE ROOT CAUSES
Aging starts in two places.
Declining NAD⁺
NAD⁺ is a tiny, fundamental chemical compound found inside every living cell in your body. It's responsible for repairing damaged DNA and regulating cellular metabolism.
∞ NAD⁺ can drop ~50% by age 60
Senescent 'zombie' cells
Senescent cells — often called 'zombie cells' — are damaged cells that permanently stop dividing but refuse to die. Instead of undergoing programmed death, they linger in tissue and secrete toxic chemicals that cause inflammation and damage surrounding healthy cells.
∞ Toxic signals damage nearby healthy cells

LONGEVITY 1 · NMN
Science's most efficient NAD⁺ booster.
-
01
Dissolves under tongue
-
02
Bypasses digestion
-
03
Enters bloodstream
-
04
Activates NAD⁺
Direct cellular entry
NMN uses its own dedicated transporter to enter cells directly — a unique delivery route that bypasses the slow breakdown steps capsules need in your gut.
Sublingual advantage
An NAD⁺ supplement or IV is too large to absorb orally, but NMN bypasses the digestive tract by dissolving in the mouth — a far more effective way to replenish declining NAD⁺.
What you feel
Clearer thinking, steadier energy, better metabolic support.
LONGEVITY 2 · FISETIN
Clear cells. Renewed life.
Cellular buildup
Zombie cells accumulate with age.
Inflammaging
Chronic low-grade inflammation spreads.
Immune disruption
Healthy tissue signaling breaks down.
Targeted clearing
Fisetin helps clear the burden.
Why a peppermint? Because delivery matters.
Longevity 2 uses a dissolvable peppermint for oral-mucosal absorption — bypassing digestive breakdown and preserving more active Fisetin: better bioavailability, more consistent delivery, faster activation.
Relative Bioavailability
Illustrative — oral-mucosal delivery preserves more active compound by avoiding first-pass digestion.
TOTAL-BODY BENEFITS
What consistent, cellular support feels like.
-
Elevated natural energy -
Clearer thinking & focus -
Improved metabolic stability -
Better long-term aging -
More balanced daily wellbeing
PURITY
Benefits backed by purity.
No fillers. No artificial sweeteners. No gimmicks. Just clean, evidence-based longevity support.

ANSWERED BY SCIENCE
Questions, honestly answered.
What makes Sybil's NMN different from capsules or powders?
Sybil's NMN is a sublingual powder — it dissolves under the tongue for direct oral-mucosal absorption, bypassing the digestive breakdown that reduces the potency of most capsules and drink mixes.
How does NMN increase energy and clarity?
NMN is a direct precursor to NAD⁺, the coenzyme cells use for energy production, DNA repair, and metabolic regulation. Restoring NAD⁺ supports the systems responsible for steady energy and mental clarity.
What are senescent 'zombie' cells, and why do they matter?
Zombie cells are damaged cells that stop dividing but refuse to die. They linger in tissue and secrete inflammatory signals that damage nearby healthy cells — a core driver of age-related decline.
Why a Fisetin peppermint instead of a capsule or gummy?
A dissolvable peppermint enables oral-mucosal absorption, preserving more active Fisetin than swallowed formats and delivering it more consistently.
Are Sybil products clean and filler-free?
Yes. Both products are third-party lab tested, filler-free, and made with clean, food-grade ingredients — 99.9% pure NMN with organic strawberry, and 98% plant-derived Fisetin with peppermint oil.
How do I trust what is in each product?
A QR code on Sybil's labels and cartons will bring you to the third party lab test for that product batch.
Why is Sybil different from other Longevity brands?
Sybil was created around one philosophy: do fewer things exceptionally well. Instead of overwhelming you with dozens of formulas, we focus on two carefully selected ingredients delivered in enjoyable formats that dissolve in your mouth - not another handful of capsules.
How long does it take to notice a difference?
Everyone is different. Some customers report feeling improvements in energy, focus, or overall well-being within a few weeks of consistent use, while others notice changes more gradually. Like most wellness routines, consistency is more important than expecting immediate results.
Can I take Longevity 1 and Longevity 2 together?
Yes. They were selected to complement each other. Think of Longevity 1 as supporting healthy cellular energy, while Longevity 2 supports your body's natural cellular housekeeping processes. The NMN powder is best taken each morning, the peppermints are to be enjoyed throughout the day.
Do I need to stop taking my other supplements?
No. Sybil is not trying to replace your entire supplement routine. Longevity 1 and Longevity 2 were created to provide two simple, targeted additions to a broader healthy-aging lifestyle. If you take prescription medications, have a medical condition, are pregnant or nursing, or have questions about combining supplements, check with your healthcare professional.
