Uncovering Depression and Anxiety With the OAp Organic Acids Profile

Do you have patients with anxiety, low mood, or fatigue—but routine labs aren’t providing answers?
The OAp™ Organic Acids Profile helps uncover metabolic and nutrient imbalances that impact brain function—offering clarity in complex mood and cognitive cases.
In this 5-minute video, Jenn Evon, MS, CNS, highlights how OAp markers reveal patterns tied to emotional and mental health, including:
- Why vanillylmandelic acid (VMA) and the HVA/VMA ratio matter for stress chemistry
- How to assess B6, B12, and folate using pyridoxic acid and xanthurenic acid
- What may signal neurotransmitter depletion, inflammation, or nutrient gaps
For patients with anxiety, depression, brain fog, or burnout, the OAp can help guide more targeted, effective protocols.
