Should Biomarkers Be Tested for ADHD Diet? 

PostedSeptember 18, 2025

ByMy Patient Advice

The idea of using ADHD biomarker testing is becoming more popular as families and professionals look for ways to tailor nutrition to individual needs. Biomarkers can provide information about vitamin, mineral and fatty acid levels, which may influence focus, mood and energy. For some, ADHD biomarker testing offers an opportunity to identify gaps that standard approaches might overlook. 

One of the main benefits is its connection to nutrient testing. By identifying deficiencies, parents and individuals can make more informed choices about diet and supplements. This helps reduce trial and error when adjusting meals or introducing new strategies. Another advantage is personalised nutrition, where diet is designed specifically around a person’s biological needs. While ADHD biomarker testing is not a diagnostic tool for ADHD itself, it can provide valuable guidance on how nutrition affects symptoms.
