This is how energy is created

It all starts in your cells

More precisely, in the mitochondria. For that, your body needs NAD⁺, and levels decline from your mid-30s onward. The second coffee at three only masks it and costs you your night.

  • The supplement NMN (β-nicotinamide mononucleotide) is a precursor to NAD⁺
  • It supports natural NAD⁺ levels.
  • No caffeine. No high, no crash.

The second lever

Power plants are aging too

Your mitochondria are the power plants of your cells. Your body clears out worn-out ones and replaces them itself, but more slowly as the years go by. What matters then is not how many you have, but how well they work.

  • This is where Urolithin A comes in. It supports your body during precisely this cleanup process.
  • It is not found in food. Pomegranates, berries, and nuts provide only the precursors. Your gut has to produce Urolithin A from them first, and not everyone can do that.
  • As a supplement, you get it directly. Without going through the intestines.

And now?

Start with NMN

NMN supports your NAD⁺ levels and is the obvious first step for most people. If you also want to support your powerhouses, you’ll find Urolithin A right below. All products can be easily combined.

In everyday life

How NMN fits into your day

One capsule in the morning, with or without breakfast. That's all you need. No measuring, no timing around your workout.

  • One capsule daily (300 mg), preferably in the morning with a glass of water.
  • Your coffee can stay. NMN contains no caffeine and does not replace it; it complements your routine.
  • Can be combined well with Urolithin A. Not together with other NAD⁺ precursors such as NR or high-dose niacin.

Honestly

What you can realistically expect

NMN is not an energy drink. It does not take effect after twenty minutes, but over several weeks, because it supplies your body with a precursor to NAD⁺.

  • The first few weeks: Make the capsule a regular part of your morning. You may not feel anything yet.
  • After four to twelve weeks: During this period, most people begin to notice their first changes.
  • Afterwards: Consistency matters more than anything else. That’s why it’s worth choosing a routine you can stick to.

    More than supplements

    What else helps with the slump

    No supplement replaces good sleep. These habits make the biggest difference, with or without NMN.

    • Morning light: Ten minutes outdoors help your internal clock more than any alarm clock.
    • Protein for lunch: A heavy, carbohydrate-rich lunch is one of the most common triggers of the afternoon slump.
    • Coffee only until noon: Caffeine continues to work for hours. What you drink at three costs you sleep at night.
    • Ten minutes of movement: A short walk after eating gets you back on track faster.

    For whom

    Who NMN is suitable for, and who it isn’t

    NMN is intended for adults in their mid-30s and older, whose NAD⁺ levels decline over the years. For some people, however, it may not be the right step, or should only be considered after consultation.

    • Fits well if you want to invest in your energy for the long term instead of seeking a short-term boost.
    • Talk to your doctor first if you take prescription medications, especially blood thinners, immunosuppressants, or diabetes medications.
    • Not recommended during pregnancy and breastfeeding, or for children and adolescents.

    FAQ

    Frequently Asked Questions

    Starting a new supplement routine can feel like a big step. That’s why we’ve compiled the most frequently asked questions and answers for you.

    • What is Youngle?

      Youngle is based in the United Kingdom and Germany and was founded by doctors and longevity researchers. We develop scientifically backed supplements for people who want to strengthen their health over the long term.

      Every product is based on peer-reviewed research, independently tested in a German laboratory, and combines carefully selected plant-based ingredients in thoughtfully developed formulations. We focus on meaningful dosages, high quality standards, and an optimal combination of the individual active ingredients.

    • When can I expect to see the first changes?

      This depends on the specific product and your individual circumstances. Some ingredients, such as creatine or apigenin, may produce noticeable effects within the first one to two weeks. Others - particularly those that support cellular processes, such as NMN or urolithin A - generally require four to twelve weeks of consistent use before initial benefits become noticeable.

      Our products are designed for long-term results that build over time. Patience and consistent use are therefore especially important.

    • How are your products tested?

      Each batch is independently tested by Limbach Analytics, a German laboratory accredited by DAkkS. Testing covers dosage accuracy, purity, and the presence of heavy metals, bacteria, fungi, and pesticides.

      The test results are available for our customers to view. We believe transparency should not be a marketing promise, but a standard.

    • Can I combine Youngle products with my medications?

      Our formulations contain well-researched ingredients in scientifically supported dosages, and every product is based on published research. Nevertheless, we cannot account for every possible interaction with medications.

      If you take prescription medications - especially blood thinners, immunosuppressants, or diabetes medications - you should speak with your doctor before taking new supplements. You can find the complete ingredient list on every product page.

    • How quickly will I receive my order?

      We ship from Germany. Within Germany, your order will usually arrive on the next business day. Delivery to other EU countries takes one to two business days.

      Shipping is free for orders of €50 or more. For orders below this amount, shipping costs are calculated at checkout based on your location.

    • Is there a money-back guarantee?

      Yes. We offer a 30-day, no-questions-asked money-back guarantee. If you are not satisfied for any reason, simply email us within 30 days with your order number - we will refund the full purchase price quickly and hassle-free.

    • Can I subscribe and save?

      Yes. All products are also available by subscription. You save 15% on every delivery and choose your own delivery interval.

      You can pause your subscription, skip individual deliveries, or cancel at any time through your customer account. No minimum commitment, no fine print. A subscription makes it especially easy to stay consistent, and that consistency is one of the most important factors for long-term results.
