Just like everything in life, not all things are equal, no matter what the ingredients list state on the bottle. This can be very critical when looking for supplements that one takes to improve their health…not hurt it. I have had a copy of the “NutriSearch Comparative Guide to Nutritional Supplements” by Lyle MacWilliam MSc, FP for years, but there is a new 2011-2012 edition that has included research about the benefits of vitamin D to overall health.
In this body of research, 3 companies rise to the top in their compliance to the highest levels of quality and ingredients; USANA Health Sciences, Douglas Laboratories, TrueStar Health. There are other 5 star companies, but these three set the “gold” standard in every aspect of measurement.
Before you invest your time and money in a particular supplement, check out the rankings and performance in this book. You’ll be amazed at the differences in quality and the science behind the supplements.
After careful review, I have switched to USANA. I’ll let you know how it goes! Here’s to your health!
