Sometimes dietary adjustments are not enough. In pursuit of the underlying cause of symptoms and ailments, the following tests may be extraordinarily helpful sleuthing tools.

  • Nutritional Deficiency Testing by SpectraCell Labs is a blood test that identifies an individual’s functional deficiency of 11 nutrients, as well as glucose-insulin metabolism, fructose sensitivity and robustness of the immune system and antioxidant levels. More info here.

  • MTHFR Genotyping by SpectraCell labs reveals flaws in two MTHFR genes (C677T and A1298C). These genes hold instructions for manufacturing an enzyme that is necessary for activating folate and vitamin B. Deficiency in this enzyme can cause or contribute to various health conditions. This test is included free with the Nutrient Deficiency Test. More info here.

  • Mediator-Release Testing (MRT) by Iso-Lab is a blood test that helps identify which foods may be causing inflammation (aka. food sensitivities). This is different, and potentially more helpful than other assays that measure IgG antibodies.
