|All mineral levels are reported in milligrams percent (milligrams per
one-hundred grams of hair). One milligram percent (mg%) is equal to ten
parts per million (ppm).
Extensively studied, the nutrient elements have been well defined and are
considered essential for many biological functions in the human body. They
play key roles in such metabolic processes as muscular activity, endocrine
function, reproduction, skeletal integrity and overall development.
The toxic elements or “heavy metals” are well-known for their interference
upon normal biochemical function. They are commonly found in the
environment and therefore are present to some degree, in all biological
systems. However, these metals clearly pose a concern for toxicity when
accumulation occurs to excess.
These elements are considered as possibly essential by the human body.
Additional studies are being conducted to better define their requirements and
