GUIA COMPARATIVA DE SUPLEMENTOS NUTRITIVOS -  1 book, (Books & Media)

Finally, a sensible guide that helps consumers navigate the maze of nutritional products on the market today! 
 
Packed with the latest findings on aging, oxidative stress and degenerative disease, the Comparative Guide to Nutritional Supplements 4th Edition is a masterful synthesis of research and analysis, and an invaluable resource for anyone with an interest in the science of optimal nutrition. 
 
The guide examines the remarkable protective powers of vitamins, minerals and antioxidants and presents scientific evidence supporting the use of nutritional supplements to help achieve optimal health. The presentation of fourteen quality-selection criteria enlightens the reader on what to look for in a high-quality nutritional supplement. 
 
Over 500 nutritional products are compared to an independent nutritional benchmark, developed from the individual recommendations of seven recognized nutritional authorities.  
 
Graphical comparisons of over 230 American and Canadian nutritional supplements, along with their Final Product Scores, allow the reader to separate the wheat from the chaff! 
 
 
What's in the Guide?  
 
This guide seeks to educate consumers about the science and value of nutritional supplementation, and to provide them with a simple, reliable tool with which to compare nutritional products.  
 
Section I: Aging, Oxidative Stress and Degenerative Disease 
 
Section I of this guide discusses the theories of aging and the intricate links between aging, oxidative stress and degenerative disease. The remarkable protective powers of the endogenous and dietary antioxidants and their role in mitigating the aging process are examined. Five degenerative disease processes are highlighted, including recent scientific evidence supporting the use of nutritional supplementation as a preventive measure. 

 
Section II: Beyond the RDA — Advanced Nutritional Supplementation 

 
Section II reviews the substantial scientific evidence employed in developing the fourteen analytical criteria imbedded in the product-rating methodology used in this comparative guide.  
Creation of the Nutrient Profile Score, based on these fourteen criteria, has been an evolutionary process. With each edition of this comparative guide, we have built on previous research as newly published scientific findings have become available. The result has been the creation of a robust analytical model, based on the scientific literature and the independent recommendations of our seven cited authorities.  
In each of the chapters of Section II, the reader is introduced to one of the fourteen criteria and the scientific evidence supporting its use. For those who find the reading a little technical, we refer you to the highlighted text. These capsule summaries will provide an overview of the subject matter without the need for detailed reading. For those who wish to explore the science of advanced nutrition, we invite you to “dive in. 

 
Section III: How the Comparisons were Made 

 
Section III provides further explanation of the Nutrient Profile Score and introduces the Blended Standard, a nutritional benchmark we have created that is based on the independent recommendations of seven scientific authorities. A brief biographical background of each of the seven authorities and their specific recommendations for optimal daily nutritional intake is also provided.  
The use of the Blended Standard, as a benchmark for optimal nutrition and the foundation for the Nutrient Profile Score, is featured. The Nutrient Profile Score is described in detail in Chapter 17. This fourteen-point score is the heart of our comparative analysis; it provides a rigorous quantitative evaluation and relative ranking of all products, based on the Blended Standard benchmark.  
Section III also provides a summary of the 25 top-rated products, listed according to Nutrient Profile Score. From this list, the top ten products are profiled. These are products of exceptional standing and merit your serious attention as a consumer. Included is a brief profile of each company, with contact information, company history and corporate vision. Points of interest on product formulations, including a breakout of the individual Nutrient Profile ratings and information on manufacturing processes (if available), is also provided. 

 
Section IV: Graphical Comparisons 

 
In Section IV, selected products from companies throughout the United States and Canada are graphically compared to the Blended Standard benchmark. With each graph, we have provided the Nutrient Profile Score for that product, illustrated as both a percentage ranking and a five-star rating. This allows easy comparison of relative product ratings.  
In writing this comparative guide, over 1,000 American and Canadian nutritional products were initially examined. Five hundred and eight (508) qualifying products, representing the best in the line-up of some 210 companies, were further evaluated and their respective nutrient contents were compared to the selected nutritional standards. Two hundred and thirty-two (232) finalists, representing the top-rated product(s) from each manufacturer, were then selected and compared graphically. (Some companies have more than one product represented, if they market in both Canada and the United States.) The graphical illustrations allow the reader to visually compare the nutritional contents of leading brand-name supplements, in relation to the Blended Standard.  

 
Practice Due-Diligence 

 
If you are using this guide to select a nutritional product, you may also wish to contact the company you have chosen and request that they furnish answers to the Ten-Point Product Quality Checklist provided in Chapter 4.  
Above all, practice due-diligence. Make certain you are providing your body with the very best nutritional supplements that science can offer — your health is too precious to compromise.
