In this episode of Power Up Recovery with Nutrition, Christina Veselak sits down with Cynthia Libert, a functional and integrative physician specializing in metabolic psychiatry, brain health optimization, and cognitive decline prevention. Drawing from her own experience with professional burnout, Dr. Libert shares how she transitioned from conventional family medicine into a root-cause, nutrition-centered model of care that restores emotional and neurological resilience.
Together, Christina and Dr. Libert explore the powerful intersection of nutrient status, inflammation, blood sugar regulation, and mental health. They discuss how targeted lab testing can reveal hidden drivers of anxiety, depression, cognitive changes, and burnout — and how precision nutrition can often restore balance faster than many expect.
Throughout the conversation, they reference the work of pioneers in functional and integrative medicine, including James Greenblatt, Dale Bredesen, William Walsh, and Dr. John Wilson, whose clinical insights into nutrient deficiencies and individualized care helped shape modern integrative psychiatry.
This episode bridges functional psychiatry, preventive brain health, and real-world clinical experience — offering both science and hope.

Practical Takeaways
Burnout is often metabolic — not simply emotional.
Testing nutrient status can reveal treatable drivers of anxiety, depression, and fatigue.
Omega-3 replenishment can produce noticeable mood shifts in a relatively short time.
Stable blood sugar and adequate protein intake are foundational for emotional stability.
Magnesium, zinc, B12, ferritin, and vitamin D are frequently overlooked in conventional mental health care.
Midlife is a powerful opportunity to prevent future cognitive decline through targeted lifestyle changes.
Prevention of neurodegeneration begins decades before symptoms appear.
