Phosphatidylserine

Exercise performance and recovery is the main area connected here, and any felt benefit should be read together with the human evidence base.

Some human supplement-context evidence is present and directly informs the score.

Key precautions
No combination caution signal is clear enough to show right now. This does not guarantee safety.
These are signals reported in studies. They do not predict what will happen to an individual.

Side effects and combination studies

No standalone side-effect or combination signal is currently clear enough to show from the collected papers. This does not mean there is no concern.

Key Evidence #1
Public scholarly dataCitation signal: 635
review

The biology of phosphatidylserine is discussed with respect to its role as a global immunosuppressive signal and how PS is exploited to drive diverse pathological processes such as infection and cancer.

Key Evidence #2
Public scholarly dataCitation signal: 423
observational

A novel mode of viral transmission is revealed, where enteroviral genomes are transmitted from cell-to-cell en bloc in membrane-bound PS vesicles instead of single independent genomes, which has implications for facilitating genetic cooperativity among viral q

Key Evidence #3
Public scholarly dataCitation signal: 358
observational

It is shown that exposed phosphatidylserine (PS) represents a neuronal ‘eat-me’ signal enabling microglial-mediated synapse pruning and a novel role of developmentally regulated PS exposure that is common among developing brain structures is identified.

Public scholarly dataCitation signal: 345
observational

It is demonstrated that the mitochondrial protein mitofusin 2 (Mfn2) protects against liver disease and binds phosphatidylserine (PS) and can specifically extract PS into membrane domains, favoring PS transfer to mitochondria and mitochondrialosphatidylethanol

Public scholarly dataCitation signal: 316
review

[Abstract]: Phosphatidylserine (PS) is the major anionic phospholipid class particularly enriched in the inner leaflet of the plasma membrane in neural tissues. PS is synthesized from phosphatidylcholine or phosphatidylethanolamine by exchanging the base head

Public scholarly dataCitation signal: 183
observational

ATG8-PS lipidation provides a specific ‘molecular signature’ for non-canonical autophagy, uncovering a novel means of detecting and monitoring this emerging pathway.
