Could a simple supplement combo help adolescents with ADHD stay on task?

Key Points:

• A study published in Nutritional Neuroscience found that a single dose of a combined L-theanine and caffeine supplement improves selective attention in adolescents with ADHD by reducing false alarms and slowing the decline in reaction time during tasks.
• The experiment involved 21 adolescents on methylphenidate and used a double-blind, placebo-controlled crossover design to compare the effects of L-theanine-caffeine, placebo, and methylphenidate on attention and brain activity measured by EEG.
• While methylphenidate improved average reaction time, the L-theanine-caffeine combination helped maintain stable attention over time and accelerated brain stimulus evaluation, with EEG results showing similar neural effects to methylphenidate.
• Researchers caution that this combination is not a replacement for standard ADHD treatments and emphasize the need for further research on long-term effects, real-world benefits, and safety before recommending L-theanine-caffeine as a supplement for ADHD management.
• Limitations of the study include a small sample size, high task accuracy causing ceiling effects, and focus on acute rather than chronic supplementation, highlighting the need for larger and longer-term studies to confirm findings.
