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

Each 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 composition of the individual active ingredients.

The quiz takes about three minutes. You answer questions about your goals, daily life, health status, and priorities. Our recommendation logic evaluates your answers and creates a personalized routine based on them.

At the end, you will see exactly which products are recommended for you and why each one fits your profile. Not a standard package applied indiscriminately, but a routine tailored to you.

That depends on the specific product and your individual circumstances. Some ingredients, like creatine or apigenin, can show noticeable effects within the first one to two weeks. Others—especially those that support cellular processes, like NMN or urolithin A—usually require four to twelve weeks of consistent use before the first benefits become apparent.

Our products are designed for long-term, gradually building results. Patience and consistent use are therefore especially important.

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

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

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

If you are taking prescription medications—especially blood thinners, immunosuppressants, or diabetes medications—you should consult your doctor before taking new supplements. The full list of ingredients can be found on each product page.
