What it is
Phosphatidylserine is a phospholipid component of cell membranes and appears in many memory-support formulas.
What the evidence suggests
Older and newer studies have used different sources, doses and populations, which makes broad claims difficult to generalize.
What to check on a supplement label
Check whether the product discloses the phosphatidylserine amount rather than only the weight of a larger phospholipid complex.
- Exact daily amount
- Extract or compound form
- Any standardization details
- Other ingredients with overlapping effects
How to interpret claims
The strongest consumer rule is to match the claim to the study. Evidence about one extract, one dose or one population should not be generalized to every product bearing the ingredient name.
