According to research published by the National Institutes of Health, overactive arginase can reduce the supply of L-arginine needed by the body for various vital functions, directly answering the question of what kills arginine in the body. The degradation of this amino acid is a complex process influenced by enzymes, disease, and inflammation, impacting critical bodily systems like the cardiovascular and immune systems.

While many amino acids are strictly essential or nonessential, a fascinating aspect of human biology is how the body's needs change over a lifetime. This dynamic process explains why arginine is sometimes considered essential and other times nonessential, depending on an individual's physiological state.

Despite a diet rich in arginine, approximately 40% of dietary arginine is metabolized during its initial passage through the small intestine. This process reveals the complex journey of how is arginine absorbed and its ultimate fate before entering systemic circulation, which differs significantly from other amino acids.

Arginine is a conditionally essential amino acid, meaning that while the body can produce it, certain conditions can drastically increase demand and lead to a deficiency. Understanding **what depletes arginine in the body** is therefore crucial for maintaining optimal physiological function and overall health.
