Please read this before relying on anything published here. Last revised September 10, 2026.
The Librarian's Regimen — every entry, page, image, caption, tag, feed item, reply to a comment and answer to a question — is published for general information and education only. Nothing on it is medical, nutritional, dietary, pharmaceutical or health advice, and nothing on it is a diagnosis, a treatment plan, a prescription, or a recommendation that any reader start, stop, continue or change any medication, supplement, food, diet, exercise, test, device or treatment. It is not a substitute for the individual advice of a licensed physician, pharmacist, registered dietitian, nurse or other qualified health professional who knows your history, your conditions, and what else you take.
This site is written by one private individual under the pen name Mr. Librarian. The author is not a physician, nurse, pharmacist, dietitian, or any other licensed or certified health professional, holds no medical qualification, and is not affiliated with any hospital, clinic, university, professional body or company. No entry has been reviewed, edited, fact-checked or approved by a physician or by anyone else holding a health-care licence, before or after publication.
Reading this site, subscribing to it, commenting on it, writing to the author through the ask page or any other channel, or receiving a reply, does not create a physician–patient, dietitian–client, or any other professional or fiduciary relationship. Any reply from the author is one reader's opinion and is subject to every part of this disclaimer.
Entries summarise published research in good faith and cite their sources so they can be checked. They may nonetheless misread a study, omit one, quote a figure that has since been corrected, or rest on research that has been superseded or retracted. Medical knowledge changes; an entry reflects what the author found on the date it carries, and the author is under no obligation to update it. Check the original sources before relying on any number, claim or conclusion here.
Where an entry names a drug, supplement, dose, diet, food, device, test or procedure, it is describing what a study did or found — not recommending it to you or anyone. Doses quoted are the doses those studies used, reported so the finding can be understood; they are not amounts anyone should take. Where the author writes what he would do himself, that is clearly labelled as one person's judgment about one person's circumstances and is not a recommendation to any reader.
If you think you may have a medical emergency, call your doctor or your local emergency number (911 in the United States) immediately. Never delay seeking care, disregard professional advice, or stop a treatment because of something you read here.
