Pyruvate dehydrogenase requires B-vitamin cofactors, thus an elevated pyruvate may be an indicator of a need for B-vitamins.

“One of the earliest markers for B6 deficiency was the urinary excretion of xanthurenic acid, which is normally a minor tryptophan catabolite. The major pathway of tryptophan catabolism proceeds via the PLP-dependent kynureninase reaction.” (Shane and Contractor, 1980)

Excretion of β-hydroxyisovalerate (3-HIA) and biotin are early and sensitive indicators of biotin deficiency.
(Mock et al., 2002)
The indicators of biotin status that have been validated to the greatest extent are an abnormally decreased urinary excretion of biotin and an abnormally increased urinary excretion of 3-hydroxyisovaleric acid.
(DRI Institute of Medecine 1998)

Urinary MMA levels are a good indication of cobalamin distribution and function since they are directly related to a cobalamin-dependent metabolic pathway.
-EJ Norman, 1982; 59(6): 11-28-1131
Methylmalonic acid (MMA) is increased in blood and urine of patients with vitamin B12 deficiency.
-Clinical Chemistry. 2001;47:1993-2002
Methylmalonate was shown to be superior to serum B12

P-Hydroxyphenyllactate is a marker for cellular mitosis. While a small amount of production is normal, indicating metabolic cell turnover, excessive production can indicate injury or possibly tumorogenesis.
