One routine. Three mechanisms. A complete daily longevity foundation for how your cells repair, protect and renew — supporting all 12 Hallmarks of Ageing, so you stay strong, sharp and unstoppable.
The Repair – NMN+ — boost and maintain NAD⁺ levels
The Protect – Glutathione+ — strengthen antioxidant defence & detox
The Cleanse – Spermidine+ — activate autophagy & cellular clean-up
The Age Defence System is your complete daily foundation for cellular health and longevity, featuring three original, clinically studied formulations designed by For Youth to work in harmony. Together they repair, protect and renew your cells — supporting all 12 Hallmarks of Ageing, so you stay strong, sharp and unstoppable.
Benefits in your daily life:
Boosts NAD⁺ for steady energy and focus
Strengthens immunity and cellular defences
Activates autophagy to clear damaged cells
Helps reduce everyday inflammation for faster recovery
Supports glowing, youthful-looking skin
Supports metabolic health and weight management
Improves sleep quality
Uses advanced, high-absorption ingredients
How it works:
The Age Defence System takes a three-step approach to revitalising your body at the cellular level. The Repair boosts and helps sustain NAD⁺, the molecule your cells need for energy and repair. The Protect shields cells from oxidative stress and environmental damage with glutathione and Glucoraphanin, a Sulforaphane precursor. Finally, The Cleanse supports autophagy to clear damaged cells, helps modulate inflammation, and combats the build-up of senescent “zombie” cells that accelerate ageing. Together, they create a powerful synergy to optimise cellular function, renew your body, and help you thrive.

How to use
Take all three together once daily in the morning, with a glass of water (1x The Repair, 1x The Protect, 1x The Cleanse). With or without food — the important thing is taking them every day.
Together, they support three pillars of healthy ageing: cellular energy (NAD+), antioxidant defence, and cellular clean-up (autophagy).
Expiry dates & Lab test reports
Triple-tested by independent labs. Unlike most brands.
We screen every batch for purity, safety, and potency—so you know exactly what’s in every capsule.
We typically ship out the latest batches, each with an expiry date at least 1–2 years ahead, ensuring lasting freshness and stability.
The Age Defence System is a next‑gen longevity stack. Its three‑product system doesn’t just support cells—it repairs, defends, and renews them.

Dr. Vincenzo Sorrentino, PhD, completed his PhD in Medical Biochemistry at the University of Amsterdam before going on to study how metabolism and nutrition affect ageing. He is a molecular biologist and Assistant Professor at the National University of Singapore (NUS), specialising in ageing, mitochondrial health, and NAD⁺ metabolism. His research has been published in leading journals including Nature and Cell Reports. His current work looks at how molecules like NAD⁺, which fuel our cells, and the maintenance of proteins in the body, can support healthier ageing.

Ask Anything.
Why should I take The Repair, The Protect and The Cleanse together?
Ageing is cell damage. Simple. Taking The Repair, The Protect, and The Cleanse together creates a synergistic trio to repair, protect, and cleanse your cells for optimal health and healthy ageing.
The Repair boosts NAD⁺ levels with NMN and keeps those levels sky high with Apigenin, powering cellular repair and maintaining your body’s natural defences as you age.
The Protect shields your cells with Glutathione and Glucoraphanin (a Sulforaphane precursor), two potent antioxidants that neutralise toxins, fight oxidative stress, and enhance cellular resilience.
The Cleanse clears out harmful "zombie cells" and reduces inflammation with ingredients like Spermidine and Quercetin, supporting autophagy and cellular renewal.
How do each of these products work?
The Repair is a supplement that helps your cells stay healthy and repair damage by boosting and maintaining NAD⁺ levels. It combines three ingredients: Uthever® NMN to boost NAD⁺ levels in your body, ApiAge® Apigenin to stop NAD⁺ from being used up too quickly, and Pterostilbene to enhance the effectiveness of your restored NAD⁺ levels. Together, they support your energy, focus, skin, and overall well-being.
The Protect is like armour for your cells, shielding them from damage and keeping them in peak condition. It works through two powerful, natural ingredients: Think of Glutathione as your body’s cleanup crew, clearing out harmful "free radicals" and toxins that can cause damage. Where as Sulphoraphane enriches your cells at a deeper level, strengthening them and supporting long-term resilience. What makes The Protect stand out is its use of the most absorbable forms of these ingredients, so your body gets the maximum benefit. Together, they protect your cells from daily stress and help you feel healthier, stronger, and more energised.
The Cleanse is a natural supplement that supports your body’s natural processes for cellular renewal and repair. It mimics the benefits of fasting by promoting autophagy, a self-cleaning process where your cells remove waste and renew themselves. It also helps reduce inflammation and clears out senescent cells—ageing cells that can contribute to damage—leaving your body rejuvenated and running more efficiently. Ingredients like Spermidine clean out cellular "muck," while Quercetin and Curcumin reduce cellular wear and tear, helping you feel revitalised and promoting healthier ageing.
Is The Age Defence System safe? Any side effects?
Safety: All ingredients in The Age Defence System are generally considered safe for human consumption. However, for all three products, it is not recommended you take these if you are pregnant or nursing. For the Protect, if you have hypothyroidism or are on thyroid medication, you should not take this product prior to consulting your physician. And for The Cleanse, you should not take this product if you are on anticoagulants, anticancer drugs, immunosuppressants, or suffering from biliary tract diseases.
Side Effects: No significant side effects have been documented in human trials. However, some participants have reported mild gastrointestinal symptoms or heart burn, although rare. If you have any concerns, discontinue use and consult a healthcare provider.
What time of day should I take the products?
Take all three products together once each morning with a meal (1x The Repair, 1x The Protect, 1x The Cleanse).
If you prefer timing each product:
The Repair: 1 capsule in the morning (with or without food). After waking, your NAD⁺ levels begin rising; taking NMN then gives this process an extra boost.
The Protect: 1 capsule daily on an empty stomach for best absorption. Time of day is flexible: Sulforaphane precursor timing isn’t critical; glutathione can be morning (daytime antioxidant support) or night (overnight repair).
The Cleanse: 1 capsule with food—ideally your heaviest meal. Morning pairs with the benefits of overnight fasting; evening supports renewal while you sleep.
Note: Consistency matters more than exact timing.
What's the difference with The Starter Kit?
The Age Defence System is a comprehensive 3-product bundle — The Repair – NMN+, The Protect – Glutathione+ and The Cleanse – Spermidine+. It covers three pillars: NAD⁺ support (energy & repair), antioxidant defence & detoxification, and cellular renewal via autophagy.
The Starter Kit is a simpler, lower-commitment entry bundle designed with single-ingredient products to help you begin your routine at a lower price point. It focuses on the essentials so you can start, assess how you feel, and then scale up.
Age Defence System — Best for customers wanting the full longevity stack and faster, more rounded coverage.
Starter Kit — Best for customers new to longevity supplements, budget-conscious, or testing tolerance before upgrading.
