What does the name Kalter Bruder® stand for?
The name Kalter Bruder® stands for our intensive cooling gel, developed by twin brothers with restless legs from Lüneburg, Germany. With its unique combination of relaxing and pain-relieving medicinal plants and a long-lasting, deep cooling effect, Kalter Bruder® provides noticeable relaxation for restless legs, polyneuropathy and joint pain.
Relieve joint pain effectively.
Joint pain is a common problem, but the causes and treatment options vary greatly - and are often misunderstood. Conditions such as gout, rheumatism or bursitis affect many people and require individually tailored treatments - but they all have one thing in common: targeted cold applications can combat acute inflammation, reduce swelling & relieve pain. However, the wrong application can aggravate symptoms, which is why cold therapy should only be applied to inflamed joints. However, the right diet, exercise and drug therapies are also crucial for success - in consultation with a doctor, of course.
If cold application is advised, the first question is the desired intensity and duration. There are a variety of options here - from ice baths to classic cold packs and alternating baths. For everyday use, expensive and complicated cryogenic devices and cold chambers are of course out of the question. Cold compresses, cold compresses and showers are easy to use, but their cooling effect usually only lasts for a short time. A cooling gel combines the benefits of an intensive and long-lasting cooling effect with simple and targeted application.

RELAXATION THROUGH COOLING
This is exactly where our KALTER BRUDER® Relax gel comes in, because we have specially tailored our recipe to a long-lasting cooling effect. The fresh gel from the aloe vera plant and arnica in particular are known for their anti-inflammatory and soothing properties. Ingredients such as menthol and camphor also have a cooling effect and can help to relieve pain and swelling.
KALTER BRUDER® offers a practical and efficient way to use the positive effects of cold therapy specifically for joint pain. Thanks to its cooling effect, the gel provides gentle and constant deep cooling without damaging the skin or restricting mobility.

VICIOUS CIRCLE TABLETS
Personal experiences of Kalter Bruder® founder Carsten
Carsten, what motivated you to found Kalter Bruder®?
"I have been suffering from restless legs for about 10 years and at some point I was prescribed tablets that are often used for RLS. However, the side effects were so severe that I had to stop taking them and since then I have been wondering what natural alternatives there are, not just for restless legs."
How do you generally assess current treatment methods for classic age-related illnesses?
"The vast majority of customers who try Kalter Bruder® have already taken tablets. There is a reason why these often very desperate people are looking for alternatives to conventional medicine....

We are Carsten and Stefan - twins from Lüneburg. We ourselves suffer from RLS and founded Kalter Bruder® to offer an alternative to conventional medicine. We were really lucky with the gel and in our magazine we explain studies, give tips on nutrition and exercise and reveal what you absolutely need to know.
