"Through proper interpretation, there exists a unique ability to recognize abnormal processes from trace mineral patterns found in the hair and other tissues. With specific dietary modifications, restoration of a more normal biochemical balance can be achieved, thereby eliminating many nutritionally related endocrine, neurological and even emotional disturbances."
David L. Watts, Ph.D.

Alliance for Natural Health

The Alliance for Natural Health (ANH) is working cooperatively to protect the future of natural healthcare.The work of the ANH aims to positively shape legislation proposed by the European Commission and regulators elsewhere in the world to allow continued access to natural healthcare approaches.

American College for Advancement in Medicine (ACAM)

The American College for Advancement in Medicine (ACAM) is a not-for-profit medical society dedicated to educating physicians and other health care professionals on the latest findings and emerging procedures in preventive/nutritional medicine. ACAM's goals are to improve skills, knowledge and diagnostic procedures as they relate to complementary and alternative medicine; to support research; and to develop awareness of alternative methods of medical treatment.

Blood analysis for minerals is a good indicator of the transport of minerals to and from the storage areas of the body (extracellular).

Hair tissue mineral analysis is a good indicator of the metabolic processes occurring within the cells (intracellular).

Mercury Policy Project

The Mercury Policy Project (MPP) works to promote policies to eliminate mercury uses, reduce the export and trafficking of mercury, and significantly reduce mercury exposures at the local, national, and international levels. MPP strives to work harmoniously with other groups and individuals who have similar goals and interests.


  • Hair specimens can be collected more quickly and easily than blood, urine, or any other tissue, using a non-invasive method.
  • Hair analysis is more cost-effective than mineral testing through other means.
  • Unlike blood, hair is less susceptible to the homeostatic mechanisms that quickly affect trace element levels.
  • Long-term deviations of mineral retention or losses are more easily detected in hair than blood.
  • Concentrations of most elements in the hair are significantly higher than found in the blood and other tissues.
  • Hair provides a record of past as well as present trace element levels, i.e. biological activity.
  • Hair provides information of substances entering the hair from the blood serum as well as from external sources.
  • Hair is invaluable in the assessment of toxic metal levels.
