Mental health, gut health, and nutrition are deeply connected — and often underappreciated.
On a recent NutraCast episode, Dr. Oscar Coetzee discusses how his early work in psychoneutrogenomics uncovered a common root among many mental health challenges: poor gut health, nutrient malabsorption, and elevated cortisol.
Dr. Coetzee is helping practitioners move upstream with AI-enabled Functional Blood Chemistry Analysis (FBCA), turning routine bloodwork into actionable insights that identify functional imbalances before disease develops. Designs for Health is proud to partner with Optimal DX to support this approach, helping clinicians efficiently translate lab insights into personalized, supplement-supported care plans.
