According to a study published in *Nutrients*, low methionine levels in hospitalized patients were associated with increased mortality and functional decline. These findings underscore the importance of this essential amino acid, so understanding what it means when methionine is low is crucial for maintaining overall health.

Approximately 1 in 28,000 individuals may have methionine adenosyltransferase (MAT) I/III deficiency, one of the primary genetic causes of high methionine, or hypermethioninemia. This condition, defined as an excess of the essential amino acid methionine in the blood, can also stem from dietary intake or underlying health issues affecting its metabolism.

According to research published in Nature Reviews Cancer, methionine metabolism is intricately linked to cell proliferation and overall health. The metabolism of this essential amino acid, which must be obtained through diet, involves a complex series of enzymatic reactions that influence everything from DNA methylation to antioxidant production.

L-methionine is an essential amino acid, meaning the body cannot produce it on its own and must obtain it from dietary intake. Found in many protein-rich foods, this sulfur-containing compound is vital for numerous bodily functions, including metabolism, tissue repair, and detoxification.
