How Kalter Bruder® works


The deep cooling relaxes your muscles and activates the body's own regeneration.

Blood supply

Increased blood flow transports harmful substances away and accelerates healing processes.

Calmed down

The anti-inflammatory properties of the medicinal plants contained can relieve pain and calm your nerves.

Ice bath from the bottle

Kalter Bruder® creates a cooling and relaxing effect from the very first application. Particularly stressed or tense areas of the body benefit from the regenerating and circulation-promoting properties of the ingredients, which, like jumping into an ice bath, can help muscles and nerves to recover .

Polyneuropathy since childhood

My doctor compared my nerves to power cables where the insulation has been eaten away in some places - the open electric shocks that act uncontrollably on my body have been bothering me for many years. As a result, I suffer from restless legs at night and from occasional muscle twitches during the day, which cause them to cramp again and again. When developing our natural gel Cold Brother®, we therefore made sure to treat the muscles that were overstrained and cramped by polyneuropathy by combining cold treatment with anti-inflammatory and relaxing medicinal plants.
