Madena

Madena (styled MADENA) is a German food-supplement company based in Cologne. It was founded in 2014 as a family business by the specialist pharmacist Rudolf Keil and his son, Maximilian Keil [2]. Its range is made up of capsules, powders, teas and drinking ampoules aimed at everyday health themes such as gut health, the body's acid-base balance, histamine intolerance and women's health.

Madena is not a cosmetics maker in the usual sense. Its link to beauty runs through a "beauty from within" line, sold under the German name Schönheit von innen, of ingestible products for skin and hair [8]. The company remains small and family-run, and it continues to publish new material and gather customer reviews on its own website.

The company's story begins before the company itself. According to the founders, Rudolf Keil started out by selling a single product in his village pharmacy, at a time when there was neither a brand nor a firm behind it [3]. Maximilian Keil says he soon saw the chance to build a company around it and to widen the range. The founders' page describes that decision as the birth of the family business.

Rudolf Keil studied pharmacy in Bonn and set up on his own as a pharmacist early in his career. He describes a long-standing interest in naturopathy, the tradition of natural and plant-based remedies, and says he worked from an early stage with cancer practices and with naturopathic practitioners. Over the years, he writes, a very large number of conversations with patients gave him a store of practical knowledge beyond textbook theory.

A personal experience shaped his focus. Keil writes that a member of his family developed a particularly aggressive form of ulcerative colitis, a chronic inflammation of the large bowel, which doctors could not cure [3]. After several months in hospital, the illness was brought to a standstill through surgery combined with partly naturopathic measures. He says this experience, more than 30 years ago, deepened his interest in gut health and led him to research and develop new products for the gut flora.

Alongside running a public pharmacy, Rudolf Keil says he works as an adviser in research. The topics he names include the effect of diet on body fat, metabolic syndrome, type 2 diabetes, tumour diseases and the human microbiome, the community of bacteria living in the body. He also states that he advised a leading club in Germany's top football league, the Bundesliga, for many years.

The company presents his background prominently. Its website carries the line "quality products from specialist pharmacist Rudolf Keil", and Madena dates his work as an independent pharmacist developing formulations to almost 40 years. The homepage lists "expertise and experience for more than 35 years" among its values; both figures refer to Rudolf Keil's career, not to the age of the company.

Madena's history as a company is short and lightly documented. The founding year of 2014 is consistent across the company's own pages, and Maximilian Keil writes that he and his father have run the business together since then. No date is given for the first product sold in the village pharmacy, so some individual formulations may be older than the company.

The founders state that they have developed more than 40 products together. Beyond the founding, no dated milestones such as product launches, expansions or changes of ownership are publicly documented.

Madena is a family business owned and run by its founders. The operating company is MADENA GmbH & Co. KG, a German limited partnership registered at the district court in Cologne, with MADENA Verwaltungsgesellschaft mbH as its general partner. According to the legal notice on its website, Maximilian Keil is managing director [7]. No parent company or wider group ownership is stated, and no acquisitions are known.

The business is small. A company profile in the LifeVERDE directory of sustainable firms lists it as having between one and ten employees, at its address on Stöckheimer Weg in Cologne [11].

Madena presents food supplements as a complement to a healthy diet rather than a replacement for one. In the company's words, sensible supplements play a central role in its philosophy alongside good nutrition, and every product should give each person a noticeable benefit in daily life. The company says it follows "the model of nature" in developing its formulas.

Its mission statement, addressed directly to customers, says Madena aims to raise their well-being over the long term and to give back "what everyday life takes from you". The brand's tagline, Nahrungsergänzung auf höchstem Niveau, translates roughly as "food supplements at the highest level".

The values listed on the homepage lean heavily on the pharmacy connection. Madena describes its formulations as being of "pharmacy quality", says it uses special branded raw materials with particular advantages, and offers individual advice based on what a customer actually needs. The formulations, according to the company, are developed by Rudolf Keil together with Maximilian Keil.

Production stays close to home. The company states that all of its products are made exclusively in Germany [2].

The Madena website invites visitors to browse by health goal, with themes ranging from gut health, immunity and weight loss to better sleep, eye health, concentration, and fertility, pregnancy and breastfeeding. Arranged by product type instead, the groups include gut products, acid-base balance, histamine intolerance, women's and men's health, vitamins and minerals, protein powders, liver products, bitters, blood vessels and connective tissue, omega-3 fatty acids, melatonin, joint complexes, antioxidants, pregnancy products and teas. A separate group covers skin, hair and nails.

Four products are highlighted on the website as particularly popular. MADENA Darmkur Forte is a gut-building course sold as a powder. The MADENA Histamin-Paket is a bundle aimed at people with histamine intolerance. Basenpulver BasenCitrate Pur is an alkaline powder linked to the acid-base theme, and Magnesium Ultra Komplex combines eight different magnesium compounds in one product.

Several ingredients recur across the range. The company sells capsules of diamine oxidase (DAO), the enzyme the body uses to break down histamine, and says its DAO is vegan and obtained from pea sprouts. Other recurring ingredients include lactic acid bacteria for the gut; rutin, hesperidin, diosmin and horse chestnut for the veins; choline, artichoke and milk thistle for the liver; and betaine HCl with vegan pepsin, a digestive enzyme. Some product names are registered trademarks, among them VenenGlück for a vein formula and BitterGlück for bitter drops. Not every product is vegan; the range also includes green-lipped mussel extract, which comes from a shellfish.

The beauty-related line, Schönheit von innen, groups 11 products taken by mouth rather than applied to the skin [8]. They include a skin vitamin complex with ceramides and hyaluronic acid, hair capsules, collagen drinking ampoules for the skin, and a version of the gut course marketed for the skin.

The company has also developed its own weight-loss programme, the MADENA-Methode. Madena describes it as a simple concept for losing weight and improving general well-being, built on three pillars: shake meals, acid-base balance and gut function [5].

The company states that MADENA GmbH & Co. KG is certified as an organic operator, a status for businesses that handle certified organic products [4]. Its legal notice names the German organic inspection body DE-ÖKO-013. Its philosophy page also displays the V-Label, an internationally recognised label for vegan and vegetarian products, the Kölner Liste, which guides athletes on supplement use, and the IFS Food standard for auditing food manufacturers. The page explains each of these labels but does not say which products or production sites hold them.

The company appears in the LifeVERDE directory under sustainable health and nutrition [10]. The directory itself notes that such profiles contain the company's own statements about its sustainability activities, and that inclusion is neither a certification nor an overall sustainability rating [11].

Madena is active. Its news blog published five new posts dated 23 September 2026 [9], and customer reviews on its website, which number more than 1,200, run into October 2026. The site is published in German, with an English-language option. The company continues to be led by its two founders, with Maximilian Keil as managing director.
