NutriStat Basic Profile, US BioTek

Optimal range:   8.5 - 34.8 umol/L

Methionine is an essential amino acid that plays an important role in the methylation cycle. Methionine is obtained from dietary intake or through homocysteine remethylation. Methionine’s dietary sources include eggs, fish, meats, Brazil nuts, and other plant seeds. Methionine is converted to the body’s main methyl donor, S-adenosylmethionine (SAM). This conversion requires the enzyme methionine adenosyltransferase (MAT).

The Methyl Histamine to Creatinine Ratio (Methyl Histamine/Crea. ratio) is a clinical biomarker used primarily to assess histamine metabolism and to indirectly gauge mast cell activity. Methyl histamine is a metabolite of histamine, a key inflammatory mediator involved in allergic reactions, immune responses, and physiological regulation, such as in gastric acid secretion and neurotransmission.

Methyl-Succinic Acid is a compound measured in urine that provides valuable insights into the metabolic processes occurring within the body. It is a key biomarker for evaluating mitochondrial function, which is crucial for energy production in cells. Specifically, elevated levels of Methyl-Succinic Acid can indicate issues with the body's ability to break down certain types of fats. This can be related to a deficiency in specific enzymes involved in the Krebs cycle, an essential energy-producing pathway.
