About Us

Information on our author and vitamin B12 expert David Rotter, as well as background information and aims of B12-Vitamin.com and Dr Schweikart GmbH.


B12-Vitamin.com is an online publication founded by Dr Schweikart in 2012. It is an independent, journalistic and non-commercial website, aiming to promote knowledge and education in the areas of holistic health, nutrition and medicine. 

At the end of 2017, the site was handed over to the Association for the Promotion of Holistic Health (Verein zur Förderung ganzheitlicher Gesundheit) based in Switzerland, which continues to operate and expand the publication. The association works according to its statute as a purely non-profit organisation. 


Vitamin B12

Vitamin B12 is one of the most important vitamins for our health. It is needed for many central biological functions and processes. Deficiency can have devastating consequences. 

The significance of vitamin B12 for our physical and psychological health remains underestimated, as does its enormous therapeutic potential. Today, more and more people are vegetarian or vegan for ethical or ecological reasons – yet such diets do not contain an optimal B12 supply. For this reason in particular, reliable information on this topic is more important than ever.

The aim of this website is to provide comprehensive information on the topic of vitamin B12 and its preventive and therapeutic effects. It is intended for all people interested in actively improving and maintaining their health, as well as for medical practitioners who want to learn more about holistic health approaches.

To this end, we systematically evaluate international scientific studies on the topic of vitamin B12 and present the key findings in an understandable and well-structured format. What is more, we maintain a lively exchange with doctors, therapist and practitioners of alternative medicine – incorporating some of their latest practice-based research. Testimonials from our readers sometimes also enter into our articles. 

In addition, we offer consumers tips and product overviews, to help our readers select the right vitamin B12 supplements for their needs.

The Activity of Dr Schweikart

The Dr Schweikart publishing company is dedicated to the international dissemination of holistic health approaches. For this reason, the following activities are underway or in the pipeline:

  • A network of well-founded online publications concerning various health topics
  • Book publications on specific health topics

  • Writing of specialised articles for various media 
  • Creation of informative short videos for social media platforms such as Facebook and YouTube
  • Development of a detailed and searchable database of therapists and practitioners
  • Knowledge network and patient information on alternative healing methods 

The History of Dr Schweikart

The publisher was founded in 2011 by Dr Jörg Schweikeart (Dr rer. pol.). Schweikart holds a Ph.D. in economics and has many years of experience in the publishing business. 

A personal upheaval and prolonged illness led to an intensive exploration of the topics of healing and health, training as a nutritionist and practitioner of alternative medicine, and finally to the establishment of his own publisher – combining both his professional and personal experience.  

Association for the Promotion of Holistic Health

After seven years of intensive publishing working, Schweikart transitioned in his career, becoming the CEO of a renowned high-quality tea and supplement supplier. At this point, he handed his publisher over to the Association for the Promotion of Holistic Health (Verein zur Förderung ganzheitlicher Gesundheit), a non-profit organisation based in Switzerland, which today upholds the online publishing activity on a charitable basis. 

The association, together with the input of Rotter and Schweikart, continues to pursue the exact same aims as before: offering a firm and reliable home for public guidance on key health topics and securing the preservation and further development of this vital knowledge.

Our Understanding of Health

Underlying Dr Schweikart as a publisher is a holistic approach to health and wellbeing that posits the human being as a unity of mind, body and soul. With this understanding, sustainable health and healing becomes possible only through the harmonious interplay of these three elements. For this reason, our work is based on knowledge from the following three major areas:

  1. Scientific research and traditional medicine 
  2. Alternative and natural medicine 
  3. Mental health and spiritual wellbeing

In the following, we will briefly outline what we mean by the term ‘holistic health’. 

A New Worldview – A New Medicine

In recent years, Western understandings of health have begun to shift; knowledge which thus far received relatively little recognition is now gaining public attention. These changing perspectives are the results of cutting-edge research and complex scientific studies, yet at the same time bring us back to many ancient, tried and tested insights.

The world of medicine is undergoing a similar development, as we can observe with the increasingly popular field of ecology. From a reductionist, mechanistic view of the world – which attempts to grasp nature and its organisms with a detached, linear logic – there has been a turn towards a more holistic understanding, which recognises how strongly all aspects of nature (including our bodies) are interconnected.

It is becoming clearer and clearer that only through a holistic approach can we truly understand and maintain health; the isolated treatment of individual aspects too often falls short and can even be counterproductive. Undeniably we can see these striking interconnections in the discoveries of numerous biochemical reaction pathways, important chemical messenger and complex regulatory mechanisms.

The Need for a Rethink 

New research clearly shows the limits of conventional treatment methods that focus only on individual symptoms. Inevitably, such methods often have knock-on effects for the entire system. 

Consequently, a rethink is becoming evermore urgent. Especially as there has been a worldwide rise in the so-called “diseases of modern life”. To an alarming extent people are suffering from health damage as a result of toxic pollution, as well as from various other mental and physical disorders such as stress, depression and burn-out. 

It is our belief that only through a holistic approach to health can we find solutions to these global problems. 

Holistic Health – Understanding Connections

The fundamental understanding in holistic health is that humans and their environment are whole, and that all individual aspects influence each other. This view is increasingly confirmed by new research that can quantify and biochemically explain such interdependencies. 

There are four major areas, which influence our overall health balance (homeostasis): 

Psychology & Mental Wellbeing 

Recent research has outlined how large the psychosomatic and emotional aspects of many diseases are. Stress in particular is becoming one of the most significant causes of illness. 

The measurable connections between body and mind make it increasingly clear that a holistic approach to treatment must also take an individual’s psychological condition into consideration. 

A balanced mind and the successful management of stress are therefore essential factors in the maintenance of good health. 


“Food is medicine” is one of the oldest pieces of medical wisdom. Nutrition has an undeniably powerful influence on health. To this end, new treatment practices such as micronutrient therapy (orthomolecular medicine), as well as various other nutritional approaches and fasting, show impressive results. 

A healthy diet is the foundation of good health; nutrients are effective therapeutic agents. 


In the last few years, the field of sport and exercise has made some incredible findings. That movement, exercise, sport and yoga help to maintain good health was always clear. However, just how influential the effects of movement are chemically-speaking on the metabolism, hormone balance and immune system, was a great surprise. 

Exercise effects all health factors to a major extent and is indispensable to maintaining good health. 


There is a monumental relationship between living environment and health, which has often been neglected. Pollution and toxins in air, food and building materials can have a devastating impact on health. 

Natural processes of avoiding and eliminating these challenges are evermore vital in the treatment of many diseases. Only in a healthy living environment can good health be sustained. 

Through all of our publications and activities we aim to underline the crucial interconnections between these four areas, in order to present effective treatment and prevention approaches.
