Methanobrevibacter smithii

The GI – Advanced Profile (US BioTek), US BioTek

Optimal range:   0 - 3.5 x10^5 CFU/g

Methanobrevibacter smithii, a prominent archaeon (=a microorganism) in the human gut microbiome, is frequently identified in comprehensive gut health tests and plays a pivotal role in the intricate ecosystem of our digestive system. This microorganism is renowned for its ability to process hydrogen and carbon dioxide, producing methane as a byproduct, and thus, it significantly impacts the overall efficiency of the gut's fermentation processes.

Methionine

Blood

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).
