According to the National Institutes of Health, caffeine is rapidly and almost completely absorbed within an hour of ingestion, which begins the process of its journey through your body before being partially excreted in your urine. This common phenomenon, often attributed to the familiar scent of your morning cup of joe, is a normal physiological process that reflects your body's efficient metabolic system.

Over 90% of ingested erythritol is rapidly absorbed into the bloodstream through the small intestine, a key metabolic difference that sets it apart from other sugar alcohols. This unique absorption pattern largely explains why it contributes minimal calories and is generally well-tolerated by the digestive system.

Unlike fat-soluble vitamins, vitamin C is water-soluble, meaning the body does not store it in significant amounts. Instead, any excess vitamin C consumed beyond what the body needs is primarily filtered by the kidneys and ultimately excreted through urine.

As the body's third most abundant mineral, sulfur is essential for various biological functions, including proper protein structure and enzyme activity. Given its crucial role, the body has a complex and efficient system to process and eliminate excess sulfur, primarily through the metabolic actions of the liver and the filtering capacity of the kidneys.

Inhibition of organic anion transporters (OATs) is a known mechanism behind certain drug-drug and drug-toxin interactions. What are oat inhibitors? They are substances that prevent or reduce the activity of OATs, altering the body's normal processes for eliminating waste products and medications. This can have significant implications for both the efficacy and safety of many therapeutic drugs.

Approximately 85% of the body's total phosphate is stored within the skeleton, yet the body maintains a delicate balance by constantly removing excess phosphate to prevent it from building up. This complex process involves multiple organ systems and a tightly regulated hormonal network to ensure proper bodily function.

Unlike fat-soluble vitamins, which can be stored in the body's liver and fatty tissues, water-soluble vitamins are not stored in significant amounts. This biological fact is the primary reason why hypervitaminosis involving water-soluble vitamins is uncommon, as excess amounts are easily flushed out through the urine.

While many believe taking high doses of vitamin C will maximize benefits, studies show that at intakes greater than 1 gram per day, the body's absorption rate drops significantly. This is because the body has specific mechanisms to regulate and manage this water-soluble vitamin, absorbing what it needs and eliminating the rest.

While excess water-soluble vitamins like C are typically excreted within hours, fat-soluble types can accumulate in the body for months. Understanding how long does it take to flush out vitamins is crucial for avoiding toxicity, particularly when taking supplements.

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.
