What does the name Kalter Bruder® stand for?
The name Kalter Bruder® stands for our intensely cooling gel, developed by twin brothers from Lüneburg, Germany, who suffer from Restless Legs.
With its unique combination of cramp-relieving and pain-soothing medicinal plants and a long-lasting, deep-cooling effect, Kalter Bruder® provides noticeable relief for Restless Legs, polyneuropathy, and joint discomfort.
When joints need quick relief.
An acute gout attack usually comes on suddenly, severely, and often at night. The affected joints are extremely painful, swollen, and hot – now quick relief is essential, meaning:
- relieving the pain
- fighting the inflammation
- reducing the swelling.
But why does such an attack occur? Gout is a metabolic disorder where uric acid levels in the blood are elevated, causing the formation of uric acid crystals that eventually deposit in the joints. An acute attack is often triggered by purine-rich foods or alcohol. If untreated, gout can become chronic, leading to severe pain, joint deformities, and ongoing inflammation.
The good news is: As painful as gout may be, it is usually quite treatable. The main focus during an acute attack is to quickly stop the inflammation. Afterwards, uric acid levels must be brought back into balance.
Below, we provide an overview of treatment approaches: from proper nutrition to acute cold therapy, which can help stop inflammation and relieve pain.
This is where our cooling gel Kalter Bruder® comes in: It provides fast relief with its long-lasting and intense cooling effect!

1. Diet & Lifestyle
An appropriate diet and a healthy lifestyle play a crucial role in managing gout. A low-purine diet can help lower uric acid levels in the blood and reduce the risk of gout attacks. Foods rich in purines, such as meat, shellfish, and especially organ meats, should be avoided, while dairy products, fruits, and vegetables are recommended.
Alcohol consumption, especially beer, should be significantly reduced or completely avoided, as alcohol inhibits uric acid excretion and leads to an increase in uric acid levels. In addition to diet, reducing fructose intake can also contribute to improved uric acid regulation. Fructose, particularly found in soft...

2. Physical activity
Regular, moderate exercise can have a positive impact on gout by stimulating metabolism and supporting uric acid excretion. An active lifestyle also helps prevent or reduce excess weight, which benefits the joints and further lowers the risk of gout attacks.
Low-impact activities such as swimming, cycling, or light gymnastics are particularly recommended, as they are gentle on the joints. Physical activity also improves joint mobility and overall joint health, which is crucial for gout management.
However, it is important to ensure that exercise is performed gently and without overloading the joints to avoid additional strain. Finding the right balance...

3. Pharmacological Therapy
Medication is a key component in the treatment of gout, especially during acute gout attacks. In such cases, drugs like colc****, non-steroidal anti-inflammatory drugs (NSAIDs), or glucocorticoids are commonly used to quickly reduce inflammation and relieve pain. Prompt and targeted treatment is crucial to shorten the duration of an attack and alleviate joint stress.
However, caution is advised with certain painkillers that can increase uric acid levels and potentially trigger a gout attack. This includes medications containing acetylsalicylic acid (aspirin).
In the long term, continuous medication therapy may be necessary to permanently lower uric acid levels and prevent recurrent attacks. Two...

4. Cold therapy
Targeted cooling can effectively help relieve pain and combat inflammation in the affected joint during an acute gout attack. Cold slows down the inflammatory process and reduces the activity of pain receptors, providing rapid relief from discomfort. Gentle, consistent cooling penetrates deep into the tissue, reaching inflamed structures and preventing the so-called “reactive hyperemia” – a counter-reaction of the body to excessive cold, which can weaken the desired effect.
However, the benefits of cold therapy only unfold when cooling is long-lasting and evenly applied. Superficial or overly cold applications with ice packs may provide temporary relief, but...
