Dietary Supplement Ingredients for Optimizing Cognitive Performance Among Healthy Adults: A Systematic Review.

Abstract in brief

• The review finds that only 9 out of 54 dietary supplements marketed for cognitive enhancement have enough research to evaluate their safety and effectiveness, but the existing studies are often inconsistent or flawed.
• There is a lack of certainty about what ingredients are actually in these supplements, making it difficult for consumers to weigh risks and benefits properly.
• The authors suggest that future research should focus on better-designed studies to provide clearer evidence, helping consumers and healthcare providers make informed decisions about using these supplements for boosting cognitive performance.
