Heavy Metal Biochemical Assessments

MercuryMercury’s recent presence in the body can be assessed with blood and urine samples because the initial half-life of blood mercury elimination is 3 days. The half-life of elimination for whole body mercury is between 60 and 90 days. Generally, the levels of mercury are below 10 mcg per liter in urine and below 40Continue reading “Heavy Metal Biochemical Assessments”

What’s wrong with hair zinc analysis?

Hair used for nutritional status of a mineral can be flawed because of exogenous contamination–from water, dust, cosmetics, shampoos, etc–and because of endogenous, nonnutritional factors such as hair growth rate, color, sex, pregnancy and age. However, I do find it quite interesting that hair analysis could indicate a history of nutrition. Historical measurements would beContinue reading “What’s wrong with hair zinc analysis?”

Use of Organic Acids as Detoxification Markers

Environmental toxins, or xenobiotics, are foreign chemicals that enter our bodies and can potentially cause harm to our organs, tissues and cells. There are more than 60,000 known everyday chemicals that we are exposed to of which at least 200 are found in newborns at moment of birth. The most prevalent pollutants nowadays are phthalatesContinue reading “Use of Organic Acids as Detoxification Markers”

How to differentiate between a B12 and a folate deficiency

Despite whether or not megaloblastic anemia is caused by a deficiency of folate or vitamin B12 (cobalamin), large doses of folate will correct the anemia (1). Because this is the case, the extra folate can potentially “mask” symptoms of vitamin B12 deficiency such as from pernicious anemia. Unfortunately, an undiagnosed chronic vitamin B12 deficiency canContinue reading “How to differentiate between a B12 and a folate deficiency”
