Tag: Fecal excretion

According to the National Institutes of Health, over 90% of all zinc eliminated from the body is excreted through the feces. This process is the body's primary method for controlling zinc levels and preventing toxicity, in addition to managing how is zinc excreted from the body via other routes like urine and sweat.

The human body cannot metabolize the sterol rings of cholesterol, so it must be actively excreted. Excess cholesterol leaves the body primarily through a multi-stage process known as Reverse Cholesterol Transport (RCT), which culminates in fecal elimination via the liver and intestines.

While the body contains approximately 2.6 grams of zinc, primarily in muscle and bone, less than 1% of it circulates in the blood and must be tightly regulated. This critical balance is maintained through a sophisticated system of absorption and excretion, defining how is zinc eliminated from the body to prevent both deficiency and toxicity.

The human body is remarkably efficient at maintaining mineral balance, with an average of 3-4 mg of zinc cleared daily through stool and urine. This intricate process involves multiple systems to prevent toxicity and maintain essential functions. This article explores how is zinc cleared from the body, detailing the complex metabolic pathways and organs responsible for regulating zinc levels.
