ORGANIC ACIDS LEARNING CENTER
Understand What Your Organic Acids Test Is Really Telling You
Articles, videos, case studies, and books to help you interpret Organic Acids Testing with clarity and confidence — and go deeper with Dr. Gail Clayton's Organic Acids Course when you're ready.
Browse Organic Acids ResourcesWhat Is Organic Acids Testing?
Organic Acids Testing (OAT) measures metabolic byproducts in urine that reflect what's happening inside your cells — how well your body is producing energy, detoxifying, digesting, and regulating neurotransmitters. On their own, these markers can look like a confusing list of numbers.
Learning to read them as a connected story — rather than isolated values — is the skill this Learning Center is built to teach. Explore a topic below, or dive into a specific article, case study, or book.
Explore by Topic
Six core areas of Organic Acids interpretation. Each will grow over time as new articles, videos, and case studies are added.
Mitochondria & Energy Metabolism
Krebs cycle markers, energy production, and what fatigue-related patterns are really telling you.
Vitamins, Nutrients & Cofactors
B-vitamin, cofactor, and nutrient-dependent markers — and how deficiencies show up in your results.
Gut & Microbial Markers
Dysbiosis, yeast, and bacterial overgrowth patterns — and what they suggest about gut health.
Neurotransmitters & Brain Chemistry
HVA, VMA, and related markers connected to mood, focus, and neurological symptoms.
Detoxification & Oxidative Stress
Glutathione status, oxidative markers, and how well your body is clearing toxic load.
Case Studies & Clinical Pearls
Real interpretation walkthroughs — how experienced practitioners read complex, overlapping patterns.

MITOCHONDRIA & ENERGY METABOLISM
What Elevated Succinic Acid Is Really Telling You
Succinic acid sits at the handoff point into the electron transport chain — learn what high and low values suggest, and the companion-marker checks that turn one number into a real pattern.
VITAMINS, NUTRIENTS & COFACTORS
What Elevated Xanthurenate Can Tell You About Vitamin B6 Status
Elevated xanthurenate is a functional B6 clue, not a static blood level — learn what it means when tryptophan metabolism backs up at a B6-dependent step.
GUT & MICROBIAL MARKERS
Arabinose vs. D-Arabinitol: Why These Two Gut Markers Can Tell Different Stories
Arabinose and D-arabinitol aren't the same marker — learn why mixing them up across lab reports can lead to the wrong conclusion about yeast overgrowth.
NEUROTRANSMITTERS & BRAIN CHEMISTRY
HVA and VMA: What These Organic Acids Markers Can Tell You About Catecholamine Metabolism
HVA and VMA reflect catecholamine turnover, but their relationship often tells you more than either marker alone — learn why the ratio matters.
DETOXIFICATION & OXIDATIVE STRESS
Recognizing Oxidative Stress on an Organic Acids Test
Oxidative-stress markers aren't a diagnosis by themselves — they're a clue that antioxidant reserve may be losing ground to demand. Learn the concept.
CASE STUDIES & CLINICAL PEARLS
When Low Values Aren't Normal: A Hypometabolic Case That Looked Fine on Paper
A quiet Organic Acids Test isn't always good news — learn why broadly low values can signal reduced metabolic throughput, not healthy metabolism.
