Supplements for Cognitive Function

What the Research Shows

Research into supplements for cognitive function shows varying levels of effectiveness. The strongest evidence among the listed options is moderate for PQQ, which has been shown in multiple randomized controlled trials to improve brain metabolism and cognitive function in both healthy adults and those with mild cognitive impairment. Caffeine also has moderate evidence for enhancing alertness and cognitive performance, particularly when paired with L-theanine to boost mood and focus. Folate is similarly supported by moderate evidence, suggesting it may help mitigate cognitive decline in older adults, though its effectiveness can depend on regional fortification policies. Other supplements show weaker or insufficient evidence. Choline and electrolytes have weak evidence, with limited or non-definitive results regarding their impact on cognitive maintenance in healthy or elderly populations. Tyrosine also shows weak evidence, with mixed results suggesting its effects on working memory may depend on an individual's baseline levels. Calcium is noted as having insufficient evidence, as mineral supplementation generally does not significantly maintain cognitive function in healthy adults.
