About this book

Liver health is one of the main pillars of overall health. The organ is exposed daily to nutritional, pharmaceutical, and environmental compounds, and keeping it functioning properly is central to preventing metabolic, inflammatory, and chronic disease.

Rising public interest in nutrition and physical performance has driven a sharp increase in the use of nutritional, dietary, sports, and herbal supplements. Used correctly, these can be valuable tools. Used incorrectly or without scientific understanding, they can cause damage that does not reverse — and the liver is usually where that damage shows.

This volume provides a scientific and accurate guide to informed supplement use: a clear account of the products available, their potential to support or harm the liver, and the principles of proper selection, dosing, drug interaction, and safety.

It is written for physicians, pharmacists, and nutritionists, but equally for athletes, people living with liver disease, and anyone considering supplements to improve their health.

What the book covers

The supplement landscape

Nutritional, dietary, sports, and herbal products — what each category actually contains.

Support or harm

Which supplements may benefit the liver, and which are associated with injury.

Proper selection

How to evaluate a product and its claims before taking it.

Dosing

Why dose matters as much as substance, and where the margins are narrow.

Drug interactions

How supplements interact with prescribed medicines, sometimes dangerously.

Safety considerations

Warning signs, monitoring, and when to stop and seek medical assessment.

Important. Herbal and dietary supplements are a recognised cause of drug-induced liver injury, and "natural" does not mean safe. Products vary in purity and labelling accuracy, and several common supplements interact with prescription medicines. Anyone with liver disease, or taking regular medication, should review supplements with a clinician or pharmacist before starting them — this book is education, not a personal protocol.
