Organic acids are products of the body’s metabolic pathways. Evaluation of these downstream metabolites from various metabolic pathways provides insight into important areas related to gut health, mitochondrial dysfunction, neurotransmitter status, indicators of detoxification and macronutrient breakdown and nutritional status. This makes organic acid testing a valuable tool to assess the functional need for essential nutrients, diet modification, antioxidant protection, detoxification, and other therapies.
