Optimal Result: 0 - 0.96 mmol/mol creatinine.

Xanthurenate is formed from an amino acid that comes from protein in your diet. High levels can indicate an insufficiency of B6, a vitamin critical for all protein metabolism. Use of medications (e.g., oral contraceptives, anti-hypertensives, and bronchodilators) and exposure to tobacco smoke, pesticides, and other agricultural products can all contribute to insufficiency of vitamin B6. Problems with balance, fatigue, and mental/emotional stability (such as PMS and ADHD) are frequently found in patients with inadequate vitamin B6. Research has shown that symptoms of autism can be ameliorated with vitamin B6 supplementation. Additionally, xanthurenate can prevent insulin from performing its vital role in blood sugar regulation, which can contribute to diabetes.
