What if your client's depression isn't a mood problem at all, but a biochemistry problem no one has tested for?
In this episode of IRH Clinician's Corner, Margaret Floyd Barry talks with Dr. James Greenblatt, where they dive deep into the world of functional and integrative psychiatry—a field where cutting-edge nutritional science meets mental health. Dr. Greenblatt, renowned author and founder of Psychiatry Redefined, shares his journey from conventional psychiatry to a root-cause approach, emphasizing how combining traditional medicine with functional testing can transform mental health outcomes. Together, they explore why nutritional status—from amino acids to vitamin D—plays a pivotal role in depression, anxiety, and even complex psychiatric conditions.
In this episode:
- The foundational lab panel Dr. Greenblatt runs first for mental health
- Why free-form essential amino acids plus digestive support beat single amino acid protocols
- Vitamin D as the most underused, best-researched nutrient in mental health
- Low-dose lithium orotate: benefits, cognitive research, and dosing cautions
- How nutrient repletion improves antidepressant response and eases tapering
- Red flags for referral and how to build a collaborative prescriber network
