I prefer to use these tests over the standard serum B12 test and MMA testing because they are easy to get, cheap, and also provide additional information on your overall health
Following high-dose IV administration (50 mg/kg), most GSH was oxidized to GSSG and cleared from circulation with a half-life of approximately 10 minutes
and 90%) [68]
The enrichment analysis of the significantly more abundant KOs in T2, T3 and T4 indicated that carbon ( metF , kdgK and abfD ), pyrimidine ( pydC and ushA ) and cysteine/methionine ( AHCY , mtnA ) were enriched in T2, arginine, alanine, aspartate and glutamate metabolism ( argB , argG , glnA ) and the pentose phosphate pathway ( TALDO1 and PRPS ) were enriched in T3 and thermogenesis/oxidative phosphorylation ( CYTB , ATPeF0A , ND1 , ND2 and ND6 ), the two-component system/ lysine degradation/ aminobenzoate degradation/ butanoate metabolism ( atoD , atoA , CYTB , tctA and kdd ) and the metabolism of glycine, serine and threonine ( kbl and thrH ) and the degradation of flavonoids ( phy ) were enriched in T5
