NutriSearch Comparative Guide to Nutritional Supplements™ 5th Professional Edition for Canada and the USA, by Lyle MacWilliam MSc, FP. Northern Dimensions Publishing, www.nutrisearch.ca ISBN 978-0-9812840-4-0
“NutriSearch’s mission is to provide consumers with scientifically based information about dietary supplements, particularly multiple vitamin and mineral supplements, so they can choose the best supplement for their particular needs.
“Included in that mission is the necessity of examining not only the nutrients included in a supplement, but also the balance of those ingredients, manufacturing practices, including testing, and other quality control concerns”. (Abstracted from Nutrisearch’s web site, www.nutrisearch.ca/)
Anyone looking for information about which supplements to use should study the Guide and follow the product recommendations. The 5th edition substantially updates information provided in the previous (2007) edition.
Update: There is now (January 2016) a Sixth Edition which updates and supersedes the 5th Edition.
