• Fatigue or low energy: Persistent tiredness, reduced stamina or feeling easily depleted.
• Mood or cognitive changes: Low mood, irritability, anxiety, poor focus or memory issues.
• Digestive discomfort: Bloating, gas, irregular bowel habits or a history of gut imbalance.
• Recurrent yeast or fungal symptoms: Thrush, sugar cravings or signs suggestive of microbial overgrowth.
• Sleep difficulties: Trouble falling asleep, staying asleep or waking unrefreshed.
• Unexplained aches or discomfort: Generalised muscle tension or physical discomfort without a clear cause.
• Skin issues: Rashes, irritation or skin symptoms that fluctuate with diet or stress.
• Blood sugar or appetite swings: Cravings, shakiness, energy dips after meals or difficulty managing appetite.
• Weight changes: Unexplained weight gain, difficulty losing weight or fluctuating weight patterns.
• Chemical or food sensitivities: Feeling unwell after certain foods, additives or environmental exposures.

The Organic Acids Test provides a comprehensive analysis of more than 70 organic acid markers from a single urine sample. These markers reflect activity across central metabolic pathways, including mitochondrial function, carbohydrate and fatty acid metabolism, neurotransmitter turnover, digestion-related microbial by-products, detoxification-associated metabolites and oxalate handling. This broad panel offers detailed insight into biochemical processes that influence metabolic efficiency and nutritional status.

The test can be clinically useful when investigating patterns related to low energy, mood changes, digestive dysfunction, nutrient insufficiency or metabolic imbalance. By examining markers linked with fungal overgrowth, bacterial metabolism, amino acid utilisation and B-vitamin demand, the OAT helps identify areas where metabolic pathways may be under strain or requiring additional support. Oxalate markers and detoxification-related metabolites further extend the assessment into areas relevant for oxidative stress and metabolic load.

OAT is often used alongside other functional tests to inform targeted nutritional strategies, guide clinical decision-making and support case management. It provides a practical overview of metabolic function that can help practitioners prioritise diet, lifestyle, supplement and therapeutic interventions. When combined with stool testing or toxin panels, the OAT can contribute to a more complete picture of metabolic health.
