My Hair Guides My Bioelement Dietary Requirements

Abstract

: Background. The bio element nutritional status may be defined as deficient, adequate, or excessive/toxic. Non-invasive method of hair collection makes it a tissue of choice for multi bio element analysis in precision medicine and nutritional epidemiology. Methods. Hair multi bio element profile of healthy 1073 subjects (339 Men. 734Women) was analyzed with the ICP MS. The frequency distribution of the hair log concentration data was used to assess the bio element nutritional status with the median derivatives bioassay. The assay allows for the reliable assessment of the bio element deficiency, adequacy, and excess. Results. Nutritional status of P, Zn, and the bio element pairs of I and Se, Ca and Mg, and Na and K are fully exposed and illustrated. The nutritional status of all twenty two hair bio elements are presented in Table 1 in their decreasing order of abundance (µg·g -1 ): Calcium, Zinc, Phosphorus, Sodium, Potassium, Magnesium, Silicon, Copper, Iron, Aluminum, Boron, Strontium, Chromium, Iodine, Selenium, and in (ng·g -1 ) for Nickel, Manganese, Molybdenum, Silver, Lithium, Cobalt and Gold. Conclusion. Hair bio element median derivatives bioassay proved to be a rapid, reliable, accurate, and fully reproducible method for assessing the bio element nutritional status, the nutritional health surveillance, and maintenance in precision medicine.
