So many of us in functional medicine use standard organic acid interpretations, but newer research is using them in a broader metabolomics assessment (the vast landscape of clinically relevant metabolites). A great example is the assessment of in-born errors of metabolism. Utilizing metabolomics resulted in a six-fold higher diagnosis rate and identification of new in-born errors, compared to traditional organic acid assessment methods. Impressive, isn’t it? Think of what it could do in a full assessment. I’m thrilled to be joined by my dear friend and metabolomics enthusiast Dr. Betsy Redmond in today’s podcast. I worked with Dr. Redmond back at Metametrix and deeply admire her passion and skill in bringing metabolomics into clinical practice. With years of experience in functional lab testing and a doctorate degree in nutrition, Dr. Redmond shares exciting pearls from the latest metabolomics research, including using urinary dicarboxylic acids to identify early cognitive decline and strategies to modulate the kynurenine tryptophan ratio (KTR) – a novel biomarker associated with inflammation, cognitive decline, and kidney disease. I was excited to hear that this ratio could also be used as an innovative biological age marker – a topic at the center of my recently published study on reversing epigenetic aging, and focus of my book, Younger You.
