Supplements for Cognitive Function
6 supplements with research evidence for Cognitive Function
What the Research Shows
Several supplements show moderate evidence for their potential impact on cognitive function. For example, PQQ may improve brain function and cognitive performance in both healthy adults and elderly individuals with mild cognitive impairment. Additionally, acute doses of tyrosine have been shown to affect working memory and response inhibition in both healthy and older adults. The combination of caffeine and L-theanine has also been linked to improvements in alertness, mood, and cognitive performance. Other supplements with moderate evidence include ginseng, which has been studied for cognitive enhancement, and folate, which may impact cognitive function in older adults, though its effectiveness may be influenced by mandatory fortification policies. Currently, there is insufficient evidence to determine the impact of betaine on cognitive health, as research into its association with homocysteine in the elderly remains limited.
