What it's actually good for
How it works
Phosphatidylserine is a phospholipid that supports cognitive function and memory, particularly in older adults with mild impairment. It is also used to blunt the cortisol response to physical and mental stress, though results in younger populations are less consistent.
It is a structural component of cell membranes that maintains fluidity and supports neurotransmitter signaling, while also modulating the hypothalamic-pituitary-adrenal (HPA) axis to reduce cortisol release.
Safety
- Generally well-tolerated at doses up to 600mg.
- May cause mild insomnia or GI upset if taken in very high doses.
- Avoid bovine-derived forms (BC-PS) due to historical prion concerns; modern plant-based forms are standard.
