The idea behind everything we make

Ageing is cell damage.

Every day your cells take hits. Energy production slows, defences wear down and waste builds up. The Age Defence System gives each of those its own formula.

  1. Repair

    01 / The Repair – NMN+

    Repair

    Your cells use NAD+ to make energy and repair damage, and levels fall as you age. The Repair supports NAD+ with NMN.

    Explore The Repair
  2. Protect

    02 / The Protect – Glutathione+

    Protect

    Stress, pollution and hard training all create oxidative stress. The Protect supports your body's own antioxidant defences with glutathione.

    Explore The Protect
  3. Cleanse

    03 / The Cleanse – Spermidine+

    Cleanse

    Autophagy is how your cells clear out what's worn out. The Cleanse supports it with spermidine.

    Explore The Cleanse

What to expect

  1. Week 1–2First changes are often felt here, usually in energy.
  2. Week 4Improvements typically build and become easier to notice.
  3. Week 12The point to judge it. Cellular change rewards daily consistency.

Everyone is different. Based on the guidance on our product pages.

  • I noted a boost in energy and improved sleep. The base takes time.. about 3-4 weeks but effects are obvious. I share the base with my hubby now and recommend others to view it as an investment in health!

    Diana N. / The Base

  • I feel less sluggish in the afternoons and seem to have a bit more mental clarity. While I can't pinpoint dramatic changes, I do feel an overall sense of improved well-being that I'm happy with.

    Leen E. S. / The Age Defence Kit

  • I have a very demanding lifestyle and this product seems to be giving me the edge I need to push through fatigue and focus with more clarity when it's most needed.

    Tommy M. / The Base

  • I've been feeling quite stress lately, especially with work - and have to say I've been feeling much more chill and relaxed since taking The Unwind every evening before bed.

    Mariam B. / The Unwind

  • Its been 18 months appx since I started with NMN + Resveratrol + Quercetin after about 8 months the effects were amazing. Just returned from Sking in Japan, strong, healthy and without any pain or stiffness. An investment in life!

    Paul S. / The Age Defence Kit

  • The product is well researched and they have excellent customer service. I feel more energetic. Looking forward to a healthier me.

Latest 5-star reviews from verified buyers on Reviews.io.

Science. Not theatre.

Advised by people who study ageing for a living.

Our formulas are shaped with our scientific advisors, who research the biology of ageing at the National University of Singapore. Every ingredient has to earn its place: credible evidence, a meaningful dose and long-term safety.

Every batch is tested by an independent lab, and we publish the certificates.

  • Dr. Jan Gruber

    Dr. Jan Gruber

    Associate Professor, National University of Singapore / PhD Biochemistry, University of Oxford

    Biochemist specialising in ageing biology, mitochondrial function and oxidative stress. His research uses simple organisms such as C. elegans to understand how ageing happens at the cellular level, and to test new ways to slow it down.

  • Dr. Vincenzo Sorrentino

    Dr. Vincenzo Sorrentino

    Assistant Professor, National University of Singapore / PhD Medical Biochemistry, University of Amsterdam

    Molecular biologist specialising in ageing, mitochondrial health and NAD+ metabolism, published in journals including Nature and Cell Reports. His research looks at how NAD+ and protein maintenance can support healthier ageing.

Our story

Life doesn't have to quietly narrow with age.

For Youth started in Singapore in 2021 with one question: what would it take to stay strong, sharp and fully yourself for decades longer?

Five years and 50,000+ orders later, the answer looks the same. Science we can stand behind. Formulas you'll actually take every day. No hype.

Jeff / Founder

Not sure where to start?

A few questions. One starting point.

Tell us about your age, goals and routine. We'll suggest where to begin.

FAQ

Ask anything.

More Questions
Do you offer a money-back guarantee?

Yes. If you're a first-time customer and a capsule supplement isn't right for you, we'll refund it. Use it as directed for at least 30 days, then email [email protected] within 90 days of delivery. The guarantee covers the first opened bottle of one product. Read the full policy.

How long until I notice anything?

It depends on the product and on you. Some people notice changes within weeks. For long-term cellular health, give it at least 12 weeks of daily use. Each product page sets out what to expect.

How do I know your products are safe?

Every production batch is tested twice: first by our manufacturer, then by an independent, certified lab in Singapore. Heavy metals are kept well within the limits set by Singapore's Health Sciences Authority (HSA), and most products are also tested for the purity and amount of the active ingredient.

We publish the certificates for every batch. Look up your batch.

I eat well. Why would I need supplements?

A good diet comes first. Some of the compounds we use, like NMN, spermidine or Urolithin A, are hard to get consistently from food alone. Our formulas are designed to fill that gap, not to replace a good diet.

Am I too old or too young to start?

Our formulas are made for adults, whether you're in your 30s, 40s, 60s or beyond. The habits you build now shape how you feel decades from now. If you have a medical condition, are pregnant or take medication, check with your doctor first.

What's the difference between healthspan and lifespan?

Lifespan is how long you live. Healthspan is how long you stay strong, sharp and active. We care about the second one: more good years, not just more birthdays.

Are your supplements suitable for all genders?

Yes. They're designed around cellular health, which matters for everyone. Individual needs vary, so start with your own goals, or take the quiz.
