Imagine feeling constantly tired, struggling with brain fog, or dealing with unexplained digestive issues. You’ve tried different diets, taken supplements, and even visited specialists, but nothing seems to provide a clear answer. This is where an Organic Acids Test (OAT) can be a game-changer.
If you’ve never heard of organic acids testing before, don’t worry—you’re not alone. Many people are unfamiliar with this powerful tool, yet it offers incredible insight into your body’s metabolic processes.
What Is an Organic Acids Test (OAT)?
Organic acids are compounds produced during metabolism. When your body breaks down food, generates energy, detoxifies, or supports gut bacteria, it leaves behind a variety of organic acids. By analyzing these metabolites through a simple urine test, we can detect imbalances in key areas like digestion, nutrient absorption, neurotransmitter function, and energy production.
OAT is a non-invasive, highly informative urine test that provides a functional assessment of health. It helps uncover hidden issues that may not be detected by standard blood work.
Who Should Consider an Organic Acids Test?
OAT is beneficial for individuals struggling with:
Chronic fatigue and low energy
Brain fog, memory issues, and mood swings
Digestive problems like bloating, diarrhea, or constipation
Skin conditions such as acne or eczema
Nutrient deficiencies that don’t improve with supplements
Unexplained weight gain or difficulty losing weight
Behavioral and cognitive issues in children, including ADHD and autism
If you’ve been dealing with these issues and haven’t found answers, OAT can provide deeper insights into your metabolic and gut health.

Organic Acids Testing & Gut Health
Your gut is at the center of your overall health. It houses trillions of bacteria that influence digestion, immune function, and even mental health. Organic acids testing can detect:
Dysbiosis (an imbalance of gut bacteria) – Elevated levels of certain organic acids indicate an overgrowth of harmful bacteria or yeast, such as Candida.
Nutrient malabsorption – Deficiencies in vitamins like B12, folate, or CoQ10 can stem from poor digestion and absorption.
Neurotransmitter imbalances – Gut bacteria play a role in producing neurotransmitters like serotonin and dopamine. An imbalance can contribute to anxiety, depression, and sleep disturbances.
Organic Acids Testing Connects the Dots

OAT measures key metabolites that reflect your body’s nutritional status, including:
Amino acid metabolism – Determines protein breakdown efficiency.
B-vitamin status – Identifies deficiencies in B1, B2, B6, and B12, which are essential for energy production and mental clarity.
Antioxidant levels – Measures glutathione, a crucial antioxidant for detoxification.
Fatty acid metabolism – Assesses how well your body is utilizing fats for energy.
Mitochondrial function – Indicates how efficiently your cells generate energy.
Many chronic symptoms can be traced back to nutrient imbalances. OAT helps pinpoint these deficiencies so you can make targeted dietary and supplement choices.
Why Is Organic Acids Testing Important?
Unlike standard lab tests that offer a snapshot of your health at one moment in time, OAT provides a more dynamic view of how your body is functioning over a longer period. This can help detect:
Early signs of metabolic dysfunction before it turns into disease.
Underlying causes of fatigue, weight issues, and brain fog, rather than just treating symptoms.
Detoxification and oxidative stress issues that impact long-term health.

How Can an OAT Transform Your Health?
Once you understand your organic acid profile, you can make targeted changes to your diet, lifestyle, and supplement routine. Here’s how OAT can help:
Personalized Nutrition – If you have B-vitamin deficiencies, increasing leafy greens, eggs, and quality protein sources can help restore balance.
Gut Healing – If the test indicates dysbiosis, you can take probiotics, reduce sugar intake, and follow a gut-friendly diet.
Energy Optimization – If mitochondrial dysfunction is detected, supporting your body with CoQ10, magnesium, and a nutrient-dense diet can improve energy levels.
If you’re feeling off but haven’t found answers through traditional testing, an Organic Acids Test is an invaluable tool for identifying hidden imbalances in your metabolism, nutrient status, detox pathways, gut health, and even neurotransmitter function. The OAT can help identify what your body truly needs to feel balanced and supported.
Think of it as a window into the intricate details of your physiology. It’s a powerful diagnostic tool that not only uncovers potential root causes of health issues but also empowers you to optimize your well-being and prevent chronic conditions before they take root.
