All facts presented in this book are based on publicly available published research

papers, documents, and studies, the majority of which have been linked in the

references. Nevertheless, in some places the author has also expressed personal

opinions, where it seems to him that the facts can be assembled to form a larger,

albeit partly speculative picture. The author has made every effort to clearly

separate facts and such interpretations in terms of language.

The publisher and author have checked the information in this work to the

best of their knowledge and belief for correctness, accuracy, and completeness

sufficient for reasonable interpretation. However, neither the publisher nor the

author explicitly takes any responsibility for the content of the work or for any

errors.

This also applies to quantities of micronutrients, drugs, vitamins, and other

supplements, as there may be differences in dosage and administration that can

result from lifestyle, gender, age, body size, and possible preexisting conditions.

Therefore, any use of any of the substances mentioned in this book should

only be carried out after consultation with a trusted physician or other medical

professional, and in any case on one’s own responsibility—the publisher and

author accept no liability.

The author does not endorse the contents of any of the cited websites.

Reference is made to their status at the time of initial publication. All citations

have been carefully checked for accuracy at the time of this writing. It is not

uncommon for the content of an online source to change or even disappear

completely. Unfortunately, the integrity of scientific material that is on the

internet can no longer be blindly trusted.
