Chromium

Hair Chromium is a good indicator of tissue levels and may provide a better indication of status than do urine or blood/serum.

Chromium is generally accepted as an essential trace element that is required for maintenance of normal glucose and cholesterol levels; it potentiates insulin fucnction. 

Deficiency conditions may include hyperglycemia, transient hyper/hypoglycemia, fatigue, accelerated atherosclerogenesis, elevated LDL cholesterol, increased need for insulin and diabetes-like symptoms, and impaired stress responses. 

Marginal or insufficient Chromium is common in the US, where average tissue levels are low compared to those found in many other countries. Low hair Chromium appears to be associated with increased risk of cardiovascular disease and an atherogenic lipoprotein profile (low HDL, high LDL). 

Common causes of deficiency are ingestion of highly processed foods, inadequate soil levels of Chromium, gastrointestinal dysfunction, and insufficient vitamin B-6. Chromium status is also compromised in people with iron overload/high transferrin saturation, because transferrin is a major transport protein for Chromium. 

Confirmatory tests for Chromium adequacy include glucose tolerance and packed red blood cell elements analysis. 

Hair Chromium (Cr) is a good indicator of tissue levels and may provide a better indication of status than do urine or blood plasma/serum (Nielsen, F.H. In Modern Nutrition on Health and Disease; 8th Edition, 1994. Ed. Shils, Olson and Shike. Lea and Febiger, Philadelphia). Hair Cr is seldom affected by permanent solutions, dyes and bleaches.

Cr (trivalent) is generally accepted as an essential trace element that is required for maintenance of normal glucose and cholesterol levels; it potentiates insulin function, i.e., as a part of ”glucose tolerance factor”. Deficiency conditions may include hyperglycemia, transient hyper/hypoglycemia, fatigue, accelerated atherosclerogenesis, elevated LDL cholesterol, increased need for insulin and diabetes-like symptoms, and impaired stress responses. Marginal or insufficient Cr is common in the U.S., where average tissue levels are low compared to those found in many other countries. Low hair Cr appears to be associated with increased risk of cardiovascular disease and an atherogenic lipoprotein profile (low HDL, high LDL). Common causes of deficiency are ingestion of highly processed foods, inadequate soil levels of Cr, gastrointestinal dysfunction, and insufficient vitamin B-6. Cr status is also compromised in patients with iron overload/high transferrin saturation because transferrin is a major transport protein for Cr.

Confirmatory tests for Cr adequacy include glucose tolerance and packed red blood cell elements analysis.
