I used Trace Elements for my nutritional balancing several years ago. Since then, my naturopath that used them is no longer in business. I have since found a nutritionist (the only one in my area that does hair mineral testing) that uses Analytical Research Labs. I have only been on the program for a week, but I am not getting near the results that I got from Trace Elements. The mineral patterns on the test graphs are similar, yet the interpretation, and supplement recommendations are a little different. With Trace elements, I began noticing a difference in the way I felt, the first day of the program. Does anyone know why it takes longer for the ARL program to work? Or, is it possible that their program might not work for me at all?
