Dietary Supplements


Book Description

The growing consumer interest in health and fitness has expanded the market for a wide range of products, from yoga mats to the multiple dietary supplements now on the market. Supplements are popular, but are they safe? Many dietary supplements are probably safe when used as recommended. However, since 1994 when Congress decided that they should be regulated as if they were foods, they are assumed to be safe unless the Food and Drug Administration can demonstrate that they pose a significant risk to the consumer. But there are many types of products that qualify as dietary supplements, and the distinctions can become muddled and vague. Manufacturers are not legally required to provide specific information about safety before marketing their products. And the sales of supplements have been steadily increasingâ€"all together, the various types now bring in almost $16 billion per year. Given these confounding factors, what kind of information can the Food and Drug Administration use to effectively regulate dietary supplements? This book provides a framework for evaluating dietary supplement safety and protecting the health of consumers.

Book Description

This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender.

The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

Dietary Supplements of Plant Origin


Book Description

Dietary supplements are estimated to be used regularly by almost 60% of the American population, and over 300 million people worldwide. An important and ever-growing portion of this market is in botanical supplements that are derived from natural plants. Natural, however, does not necessarily mean safe, and although plants can provide health-essential and health-improving nutrients they can also provide toxic compounds. While the use and sales of botanical supplements continues to expand rapidly, scientific understanding of the efficacy and safety of these products remains limited. The aim of Dietary Supplements of Plant Origin is to give both the general and specialized reader a comprehensive insight into the most recent findings in this interesting area of dietary supplementation. It is hoped that this book will shed a new light on this topic and impact positively upon the health of people in this new millennium.
