Minerals are the spark plugs of our nervous system. They regulate what nutrients and hormones get into the cell. When our mineral levels are imbalanced, our nervous system becomes imbalanced. Our adrenals, thyroid, and insulin hormones become compromised as a result. Testing the hair through mass spectrometry allows us a highly accurate measure of these essential nutrient levels, rather than common blood tests which are notoriously inaccurate for these measurements.
