In this episode of the Peptides and Longevity Podcast, host Michael interviews board‑certified holistic nutritionist and functional genomics practitioner Debbie Brick about the role of genetic testing in functional medicine. Debbie shares her personal motivation—her husband’s severe ulcerative colitis—and her extensive certifications (holistic nutrition, functional genomics, autoimmune, paleo, heart‑math). She explains how MaxGen Labs’ flagship panel, “The Works,” combines three sub‑panels (function, food, fitness) to provide a DNA‑based blueprint that guides diet, supplement selection, exercise, and lifestyle interventions. Real‑world examples illustrate how genetic markers can motivate patients to avoid gluten, identify egg intolerance, or explain why a keto diet fails for some individuals. The conversation covers test logistics (simple cheek‑swab, in‑house processing, anonymized sample IDs), data‑privacy policies, and the cost‑effectiveness of a one‑time DNA test versus repeated blood, stool, or organic‑acid panels. Debbie notes that genetics reveal predisposition, not current deficiency, so follow‑up labs are still useful after dietary changes. She discusses the evolution of the test (adding new SNPs over the years) and the importance of evidence‑based gene selection. Listeners are directed to NextGen Labs’ website, practitioner directory, YouTube channel, and private Facebook groups for education and support. The episode is punctuated by sponsor messages for Integrative Peptides.
