Trace Elements, our lab of choice here at MineralsandHealth.com and with whom we work, has been a pioneer and leader in HTMA testing and mineral research since the 1980s.  Its founder, Dr David L. Watts, in his collaboration with Dr Paul Eck, developed much of the science used today in addressing mineral imbalance through HTMA, along with making the connections between various health conditions and their reflection in specific hair analysis mineral patterns.

On this page, we present a few selections of newsletters from their catalogue of publishings spanning 3 decades.  The lab's full library of newsletters is available at: https://www.traceelements.com/EducationalResources/NewsLetter.aspx
