Live and sleep in harmony with your internal clock.

Improve your sleep quality and daily life.

Are you suffering from poor sleep and feeling exhausted? Does fatigue affect your daily life?

Coffee may be delicious, but it’s not a long-term solution.

Science has the solution for you!

The RNA analysis is based on extensive research conducted by Prof. Dr. Achim Kramer from Charité – Berlin University Medicine, Europe's largest university hospital.

The world’s first RNA hair test for your internal clock.

The BodyClock RNA Hair Test analyzes time-regulating genes in your body to determine your circadian rhythm—your "chronotype" (whether you're an early bird, a night owl, or somewhere in between). It provides the optimal times for you to sleep, eat, drink coffee, exercise, work, helping you align your daily routine with your internal clock. By doing so, you can sustainably improve your sleep and overall well-being.

Personalized recommendations tailored to your individual internal clock.

This is how our test has improved the lives of our customers.

Five weeks after receiving their test results, we asked our customers for feedback. Here's what they shared with us:

  • I was very surprised by the results. Suddenly, getting up early worked well for me. I used to struggle with this and always felt extremely tired. But now that I'm waking up at the right time, I feel much more energetic. The test went well and was conducted smoothly.

    Bianka S, 27

  • I feel more in tune with my rhythm. I'm sleeping through the night better and feel like I'm sleeping more deeply. I stick to my coffee schedule, with a maximum of two latte macchiatos a day.

    Diana D, 34

  • In the evenings, I no longer feel the pressure to achieve exceptional things and instead, I tend to shift these tasks to the mornings on weekends.

    Bettina A, 44

  • It’s official: I’m not lazy; I just have a good reason to sleep in later than everyone else.

    Jannick B, 34

  • I always suspected I was a morning person, but it still shocked me to find out just how extreme it is. It was a huge surprise, but it helped me realize that there’s no point in fighting against my internal clock. I get tired at 8 PM and naturally wake up at 4 AM without an alarm. I used to force myself to stay up and watch a movie or lie in bed until 6 AM, but it only left me exhausted the next day.

    Anna T, 31
