The Amazing Life of Hans

At 91 years old, Hans is a master of perseverance. He knows polyneuropathy, a constant companion that creeps up on him at night and disturbs his sleep, only too well.

After many visits to various doctors, Hans only found temporary relief. Over time, his body adapted to the painkillers, which led him to use them sparingly, reserving them for social events so that he could be fully present.

In his day-to-day life, in the comfort of his own home, Hans Wiebe relied on his willpower and a new discovery – Kalten Bruder. This inconspicuous but effective pain relief comes in a green bottle and is faithfully stored in his fridge. It helps...

Judith always has Kalter Bruder® on her bedside table.

Judith has been suffering from restless leg syndrome for about five to six years and has offered to share her experiences with us.

Judith, how do you experience your symptoms? It always starts in the evening with a ‘burning’ sensation in the sole of my foot and sometimes I feel a more intense nervousness in my calves as well. I can't stand warm socks or a blanket over my feet in the evening for very long, and in the summer with the added heat, it's even more intense.

What have you tried so far? I've already had a few medical treatments with a neurologist, but the tablets or plasters only helped a little, which...

A true treasure

"I rarely give a review, but I would like to make my contribution here! This is a miracle product. Pleasantly cooling at first, then warming, never annoying, and the body absorbs it as relaxation. When something is good, you want to share it! Thank you! You are valuable people!!!’

Peter from Maxhutte Kalter Bruder® fan since 09.2023

Five stars are not enough

"Unbelievable, the gel works like a miracle! The stress-ridden nights are over, I can sleep again without restless legs and the constant need to pace up and down. Thank you!’

Waltraud from Kassel Kalter Bruder® fan since 10.2021

Never again without!!!

"I am impressed by how the gel works. Slowly and steadily, a pleasant coldness develops, which covers the symptoms of RLS. It feels like a pleasant, cool distraction that makes the nights bearable again. Thank you guys for having the courage to invest money and passion in the development of "Kalter Bruder". For me and for many others, you are heroes 👏"

Karina from Berlin Kalter Bruder® fan since 08.2024

Super cold and super effective

"Pretty cold / persistent. Pain gone immediately and vegan too😂. I've been using it for 3 days and have already recommended the product 3 times..."

Lutz from Hamburg Kalter Bruder® fan since 10.2024

Super hoch 3

"I've suffered from RLS since my pregnancy nd it has remained with me afterwards. I've been using Kalter Bruder® for a year and a half now and it has helped me sleep better again! I've been to many doctors, but Kalter Bruder® helped me. I highly recommend it."

Anna from Munich Kalter Bruder® fan since 06.2023

Günter from Raschau Kalter Bruder® fan since 01.2024

This is what I was looking for

"Hello, I was very excited after reading the comments about this "miracle weapon"... and I can only agree with these reviews. Experiencing this cooling sensation the first time I applied it was really something special... and it helps. After just two days I hardly had any symptoms and the pain in my knees had also significantly reduced. No more tablets. Thank you very much!!!!"

Andrea from Berlin-Mahlsdorf Kalter Bruder® fan since 10.2021

Highly recommended

"The gel is amazing. Finally something that helps. It's really great for pain. It cools and soothes."

Joachim from Wesselburen Kalter Bruder® fan since 10.2023

Very satisfied

"I tried the gel yesterday after the half marathon. It cools pleasantly and lasts a long time. It speeds up the regeneration and thus shortens the recovery time."

Christian from Remscheid Kalter Bruder® fan since 06.2024

Great

"My husband uses it for RLS and has had very good experiences with it. It helps him to fall asleep and also to relax at night. He has been a loyal customer ever since."

Elke from Munich Kalter Bruder® fan since 12.2023

Best ointment I've ever had!

"Kalter Bruder is very, very effective at relieving my nerve pain. Great application and practical bottle. The tube is perfect for travelling!"

Christina from Lemgo Kalter Bruder® fan since 08.2024

A miracle

"I have already tried several ointments and cooling gels without satisfactory results. Most of the time the soothing effects were too slight or only lasted for a short time. Then I ordered KB and the first application calmed my legs. What a miracle! I am thrilled and finally have peaceful nights again. Thank you from the bottom of my heart."

Marco from Mannheim Kalter Bruder® fan since 09.2023

Finally...

"...a good night's sleep! No more RLS, just being able to fall asleep and sleep through the night without having to take medication."

Renate from Ahrensburg Kalter Bruder® fan since 08.2024

Exceeded expectations

"Finally a remedy that REALLY works"

Maik from Hamburg Kalter Bruder® fan since 10.2024

Finally the right help! Well done guys!

"After trying almost all ointments, creams and gels, your composition is probably the best. Immediate success after one application and I slept through the night. Thanks!"

Rainer from Frechen Kalter Bruder® fan since 08.2024

Amazing❣️

"I developed polyneuropathy after chemotherapy, which has a huge impact on my life! The gel helps me! It cools and lets me feel my previously “almost” numb feet again, so that I can drive again without any problems! THANK YOU THANK YOU!"

Hannelore from Berlin Kalter Bruder® fan since 08.2023

Good stuff

"Anyone who doesn't know Kalter Bruder® has missed the boat!"

Uwe from Herne Kalter Bruder® fan since 08.2023

I can sleep 😲

"The surprise is great - it works!! Until now, my nights were characterized by 3 hours of sleep spread over the night. My fidget leg kept reminding me of itself with burning pain. The result was a permanent state of exhaustion during the day. Now I massage in the "Cold Brother" and fall asleep like a baby ☺️. I had forgotten how easy sleep actually is. Thank you so much for this experience!"

Birgit from Buchholz Kalter Bruder® fan since 10.2021

Kalter Bruder® in Polyneuropathy

"This product is great. It helps me with nerve pain in my legs and feet. Would recommend it anytime!"

Helga from Arnsberg Kalter Bruder® fan since 08.2024

Very cool

"It really helps. If I forget to take it, my hot feet will wake me up. Then reaching for the “bottle” helps 😆🛌’

Monika from Zurich Kalter Bruder® fan since 07.2023

Incredible

"Hi guys 😉 after two applications, i.e. two nights with “Kalter Bruder”; here's my first verdict. I'm overwhelmed by the effect!!! You weren't exaggerating in your advertising of the product. I was able to fall asleep quickly and stay asleep almost through the night. It's sooooo nice, thank you and very warm greetings"

MEET THE FOUNDERS OF KALTER BRUDER®

Here’s a little more about us. We created this website to reach even more people struggling with restless legs and to share our accidentally discovered ‘miracle weapon’ with them. Because behind our gel Kalter Bruder® there are actually two brothers - twins to be precise - And here, you can read our story. Enjoy! :-)

Hey there! You’ve probably read my little ‘story’ above—but what else is interesting to know about me? Well, for starters, I make music and am currently working on releasing my first album as a singer-songwriter. Like Stefan, I also enjoy sports—especially tennis—and love cooking for my family of four, usually something with lots of organic veggies. We live quite modestly in our small hometown of Salzkotten, trying to buy as few ‘new’ things as possible for the sake of the environment and our storage space. I also love dragging the family out into the great outdoors whenever I can, preferably on camping trips surrounded by nature.

Founder

Hi there! I’m Stefan, 37 years old, and I come from the beautiful town of Lüneburg. For many years, I worked in the medical technology field, advising specialists and surgeons in orthopedics, spinal surgery, and trauma surgery, before eventually transitioning to the pharmaceutical industry. This intense time, filled with countless professional discussions, training sessions, and hands-on experiences, has made the topics of sports and daily movement especially important to me. Not only is it my personal passion, but it’s also one of the key pillars of maintaining a high quality of life and treating various conditions and ailments.
