Supplements

Dietary supplements made from foods, herbs and their constituents are a rapidly growing market sector. Consumers often view food supplements as ‘natural’ and therefore safe; however, supplements are regulated as foods rather than as pharmaceuticals and so are not as closely monitored as may be necessary. With the commercial market in these products growing, this book provides essential research into their safety, efficacy and potential risk of interaction with pharmaceuticals. Following an introductory chapter, part one covers the chemical composition, manufacture and regulation of dietary supplements. Part two looks at the effectiveness of different types of dietary supplement and methods of evaluation. Finally, part three focuses on supplement safety. Reviews the design, production and regulation of dietary supplements. Analyses the potential for pharmacokinetic and pharmacodynamics interactions between dietary supplements and pharmaceuticals. Offers reviews of important clinical studies on the efficacy of dietary supplements for range of conditions.

The authors give each supplement a one-to-five-star rating based on the level of scientific substantiation for each of its major claimed effects.

A quick-reference appendix lists all the supplements alphabetically with their star ratings.

The use of dietary supplements is often promoted as a solution to a number of nutrition problems, including general dietary patterns and nutrient intakes, malnutrition in the elderly, the nutritional needs in pregnant women, poor nutrient intakes in low-income children, the iron needs of infants after 6 months, and the prevention of diseases. Although there are situations where the use of vitamin and mineral supplements can improve the health of certain individuals, the consumption of conventional food continues to be the preferred method to improve nutritional and health status. This important book examines many of the issues that dietary supplements face today. One such controversial issue is whether the use of dietary supplements should be included in food-stamp plans. Also questioned is the regulation of some of the more controversial dietary supplements such as ephedra, and if they should be available as over-the-counter or rather be made prescription-necessary medications.

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.
