Most people think of ageing as grey hairs and joint pain.
But real ageing starts much earlier — deep inside your cells .

At For Youth, we don’t see ageing as some mysterious force.
We see it as what it is:

Ageing is cell damage.

And if damage is the problem, then longevity isn’t about magic pills or miracle cures.
It’s about helping your cells repair , protect , and cleanse themselves — every day.

That’s what the Age Defence System is built for.
A science-backed longevity protocol created in collaboration with Professors Jan Gruber and Vincenzo Sorrentino at NUS — both world-class researchers in the biology of ageing.



Why Most Anti-Ageing Supplements Don’t Cut It

Search for “best supplements for longevity” and you’ll find everything from NMN to collagen to exotic herbs.
But most of these products treat symptoms — not causes.

True longevity begins by addressing the 12 Hallmarks of Ageing — the biological drivers behind why we age.
To slow down ageing , you need to address these at the source.



The 12 Hallmarks of Ageing — and What to Do About Them

Scientists have mapped out 12 distinct processes that lead to biological decline. They include things like DNA damage, faulty mitochondria, chronic inflammation, and accumulation of senescent cells. Each one chips away at your vitality over time.

Here they are:

  1. Genomic Instability – DNA damage

  2. Telomere Attrition – Shortening of chromosome caps

  3. Epigenetic Alterations – Gene expression errors

  4. Loss of Proteostasis – Faulty or misfolded proteins

  5. Disabled Macroautophagy – Blocked cellular cleanup

  6. Deregulated Nutrient Sensing – Broken metabolic signals

  7. Mitochondrial Dysfunction – Declining energy production

  8. Cellular Senescence – Zombie cells

  9. Stem Cell Exhaustion – Reduced repair capacity

  10. Altered Intercellular Communication – Mixed signals between cells

  11. Chronic Inflammation – Ongoing immune stress

  12. Dysbiosis – Gut microbiome imbalance

Enter: The Age Defence System

Not just one supplement — but three. Each targets different hallmarks of ageing.
Individually powerful. Together, they form a daily protocol to keep your cells younger for longer.



🧬 The Repair – NMN + Apigenin + L-Tryptophan

“Fuel your NAD+, fix your DNA, reset your rhythm.”

  • NMN is a direct NAD+ precursor, essential for DNA repair, energy, and mitochondrial health

  • Apigenin helps block CD38, which depletes NAD+

  • L-Tryptophan supports serotonin and circadian rhythm

Targets: Genomic instability , epigenetic alterations , mitochondrial dysfunction , stem cell exhaustion , telomere attrition , nutrient sensing


🛡 The Protect – Glutathione + Sulforaphane

“Strengthen your defences. Every cell, every day.”

  • Glutathione is the body’s master antioxidant

  • Sulforaphane (from broccoli extract) activates the Nrf2 pathway for cellular protection and detox

Targets: Chronic inflammation , loss of proteostasis , oxidative stress , intercellular communication



🧼 The Cleanse – Spermidine + Curcumin (phytosome) + Quercetin (phytosome)

“Clear the waste. Clean the slate.”

  • Spermidine activates autophagy — the body's own cellular recycling

  • Curcumin and Quercetin (phytosome forms) clear senescent cells and reduce inflammatory burden

Targets: Autophagy , cellular senescence , dysbiosis , inflammation , loss of proteostasis



How It All Maps to the Hallmarks of Ageing

Cellular Senescence

Stem Cell Exhaustion

Altered Intercellular Communication

Chronic Inflammation
Dysbiosis



Built by Scientists, Not Marketers

The Age Defence System was developed with two scientists who don’t just study ageing — they build tools to slow it down:

  • Jan Gruber – A biogerontologist whose lab focuses on how molecular repair mechanisms can extend lifespan.

  • Vincenzo Sorrentino – A cellular ageing expert focused on mitochondria, NAD+ metabolism, and how hallmarks of ageing interact.

They brought their research into the real world — so you can bring longevity into your daily life.

How to Live Longer (and Better)

You don’t need miracle promises or 30-pill stacks.
You need a strategy.
One that helps your body repair, protect, and cleanse — so you can do more, for longer.

That’s what the Age Defence System is for.
Backed by science. Built for life.
