For all subjects, the concentration of plasma cystathionine in fasting blood samples taken before and after the supplementation period will provide a functional measure of vitamin B6 nutritional status. (NCT01128244)
Timeframe: Fasting blood samples will be taken at baseline and after 28 days of vitamin B6 supplementation.
| Intervention | micromol/L (Mean) | |
|---|---|---|
| Baseline prior to vitamin supplementation | After 28-days of vitamin supplementation | |
| Plasma Cystathionine Concentration | 0.14 | 0.13 |
For all subjects, the concentration of plasma pyridoxal phosphate in fasting blood samples taken before and after the supplementation period will provide a direct measure of vitamin B6 nutritional status. (NCT01128244)
Timeframe: Fasting blood samples will be taken at baseline and after 28 days of vitamin B6 supplementation.
| Intervention | nmol/L (Mean) | |
|---|---|---|
| Baseline prior to vitamin supplementation | After 28-days of vitamin supplementation | |
| Plasma Pyridoxal Phosphate Concentration | 25.8 | 143 |
Data from analysis of serine, methionine and leucine in the timed blood samples of all subjects will provide a measurement of the metabolic rate of homocysteine remethylation from serine-derived carbon before and after vitamin B6 supplementation. These flux values may be slightly higher than flux of total homocysteine remethylation in Outcome Measure 1 because of the small contribution of methionine salvage to the flux measured in Outcome Measure 2. (NCT01128244)
Timeframe: Blood samples will be taken prior to infusion and at 0, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 7.5, and 9h. Infusions will be conducted at baseline and after 28 days

| Homocysteine Remethylation Flux From Serine | 6.60 | 6.92 |
For all subjects, analysis of blood samples before and after vitamin B6 supplementation will allow evaluation of discriminating biomarkers using targeted metabolite profile analysis of one-carbon metabolism and tryptophan catabolism constituents. Also, we will conduct exploratory evaluation and potential identification of new biomarkers using metabolomics analysis on subjects before and after vitamin B6 supplementation. (NCT01128244)
