Ingredient and preparation

Phosphatidylserine is a phospholipid; supplement products can differ in source and amount.

Sources: National Library of Medicine, PubMed

Evidence and limits

The cited systematic review covered 11 controlled studies of citicoline or phosphatidylserine-containing treatments in mental disorders. Findings were heterogeneous and inconsistent, with high risk of bias, so it does not establish a cognitive-enhancer effect for a retail product.

Sources: National Library of Medicine, PubMed

Safety and a useful record

Product source, medicine context and the population studied matter. Do not infer suitability from a cognitive-performance label.

Sources: National Library of Medicine, PubMed, National Center for Complementary and Integrative Health

Record source material, amount on label, other cognitive or sleep changes and the outcome being followed.
