Selenium Supplementation and Its Effect

While optimal selenium levels are imperative for proper thyroid function, abnormally high selenium intake can be toxic – causing gastrointestinal disturbances, changes in nails and hair, weakness, convulsions and decreased cognitive function. So it’s important to understand the ways in which we take in selenium, both in the diet and as supplements. A balance of nutrients is required by our bodies to maintain good health, and selenium (Se) is an important one that often gets overlooked. This essential element is a required component of the selenoproteins, which include those that are needed to convert thyroid hormone from the inactive to the active form, and...

An Essential Element? Bromine

Bromine should be recognised as the 28th essential element for all species, from fruit flies to humans, in according to researchers at Vanderbilt University. Study results were published 2014 in Cell, and demonstrate that without bromine, collagen type IV molecules will not bond together properly to form the structural proteins of connective tissues, leading to disrupted tissue development.   This figure demonstrates bromines role as a co-factor in formation of collagen IV crosslinks:  Image Source: McCall S, Cummings C, Bhave G, Vanacore R, Page-MCaw A, Hudson B. Bromine is an essential trace element for assembly of collagen IV scaffolds in...

Element Testing – Why Sample Type Matters!

Urine, serum, plasma, whole blood, red blood cells, feces, hair, fingernails … the list goes on. How do you decide what biological sample(s) to use for element analysis? Can results be compared to scientific literature or do they have clinical significance? Is it possible for values to be elevated or low in one sample type and normal in another? Do test results indicate recent intake, body burden, acute toxicity, chronic toxicity, deficiency, or homeostatic regulation? These are just some of the questions facing a testing laboratory when they want to develop and validate essential and toxic element profiles that will...
