Visceral Organ and Muscle Tissue K Vitamer
As can be seen from the table, the initial mean values of glutathione (GSH), oxidized glutathione (GSSG), S-adenosylmethionine (SAM), and four of the folate vitamers
were significantly different from their laboratory reference values.
However, the good news is that another form of vitamin B6, pyridoxal-5'-phosphate (a different B6 vitamer
), offers anti-glycation benefits that scientific studies suggest may have similar properties as pyridoxamine plus better inhibitory effects against lipid glycation.
For example, Erin Silva, MS, RD, registered dietitian and technical marketing manager, Vitamer
Labs, Irvine, CA, says, "Manufacturers need to keep current with the trends--but at the same time, invest only in science-based products.
Concentrations and percentage distributions for each thiamine vitamer
are listed in Table 2.
Encore is vigorously pursuing the use of this vitamer
, specifically in conditions related to disordered sodium excretion (e.g.
We tested linearity at concentrations greater than and less than endogenous vitamer
concentrations (see the experimental section in the online Data Supplement).
Determination of the BZ vitamer
flavin adenine dinucleotide in whole blood by high-performance liquid chromatography with fluorometric detection.
calibrators were checked (using this assay) for the presence of other vitamin [B.sub.6] or vitamin [B.sub.2] forms.
Results from this study showed a wide range of values for the [B.sub.6] vitamer
and metabolite content of the specimen.
In human plasma, vitamin [B.sub.6] vitamer
concentrations are low unless the person takes supplements containing vitamin [B.sub.6] (6).
Additionally, different types of anticoagulants have been used for the preparation of plasma, and this may influence sample stability and relative vitamer
