About the book

Concerns about food intake choices have prompted individuals to question if they are indeed meeting nutritional guidelines for good health. In the belief that they may not be meeting the required levels of nutrients, either justified or not, they take supplements as insurance towards nutrient adequacy and good health. This concept of taking supplements has gained popularity in recent years. Recognizing the potential for a business opportunity, business sectors around the globe are now offering a wide range of dietary and nutritional supplements. This increase in the intake and sales of supplements has raised serious concerns among health professionals and government regulatory agencies. Questions are now being raised as to the scientific evidence in support of supplements and possible adverse effects. Recognizing the importance of the issue of dietary supplements, this book is being published to provide current knowledge on the research that is being conducted and provide science-based opinions of the use of supplements. It is the hope of the editors and the publisher that the information provided in the chapters of this book will lead to better and safer use of supplements leading to good health.

Introducing your Author Service Manager

Mrs. Blanka Gugic

As an Author Service Manager, my responsibilities include monitoring and facilitating all publishing activities for authors and editors. From chapter submission and review to approval and revision, copyediting and design, until final publication, I work closely with authors and editors to ensure a simple and easy publishing process. I maintain constant and effective communication with authors, editors and reviewers, which allows for a level of personal support that enables contributors to fully commit and concentrate on the chapters they are writing, editing, or reviewing. I assist authors in the preparation of their full chapter submissions and track important deadlines and ensure they are met. I help to coordinate internal processes such as linguistic review, and monitor the technical aspects of the process. As an ASM I am also involved in the acquisition of editors. Whether that be identifying an exceptional author and proposing an editorship collaboration, or contacting researchers who would like the opportunity to work with IntechOpen, I establish and help manage author and editor acquisition and contact.
