Chromium (Cr) - hair


This trace element is required in extremely small amounts and is required for insulin to transport glucose into the cells. Chromium levels have been shown to decline with age.

A chromium deficiency produces a mild diabetic state, and diabetics make better utilisation of insulin when taking chromium supplementation. Chromium deficiency has also been linked to metabolism of cholesterol and coronary heart disease, and low sperm production.

Sugar and refined foods are low in chromium (it is lost during food processing), but they cause a rapid increase in insulin levels which requires additional chromium. This process may also lead to the loss of chromium in the urine.

Good food sources include meats (particularly calf’s liver), whole grains (whole wheat bread and cereals), brewer’s yeast, clams and cheese.

The average intake of chromium is 25-50 micrograms, but 200mcg per day of chromium GTF (glucose tolerance factor) is used for supplementation of a deficiency.

Because chromium is present in such small quantities in the body it is extremely difficult to measure. Chromium levels in plasma and hair can be measured at Biolab and there is reasonable correlation between the levels in these tissues. Urine levels are best for detecting raised levels of chromium.
