Nutritional Organic Acids (Urine) - DUTCH

These organic acids act as functional markers of nutrient deficiency. When the body has inadequate cellular levels of vitamin B12, vitamin B6 or glutathione, levels of their corresponding organic acid build up and spill into the urine. In some cases, these markers are more effective than measuring the nutrient directly.

Kynurenate (Dutch)

Optimal range: 0 - 7.3 ug/mg

Kynurenate is product of the metabolism of L-Tryptophan and appears in urine in Vitamin B6 deficiencies. Your body needs vitamin B6 (pyridoxine) to utilize amino acids derived from dietary protein.

Xanthurenate

Optimal range: 0 - 1.4 ug/mg

Your body needs vitamin B6 (pyridoxine) to utilize amino acids derived from dietary protein. Inadequate vitamin B6 is one factor that leads to increased concentrations of kynurenate and xanthurenate in urine.
