The review
Why we put this on the shelf.
Phosphatidylserine is a phospholipid that's concentrated in the brain. Clinical research shows benefit for age-related cognitive decline, mental focus under stress, and cortisol modulation post-exercise.
We carry PS 100 (Phosphatidylserine) because Thorne sets a bar most consumer-facing supplement brands don't clear: NSF-certified manufacturing, in-house clinical research with Mayo Clinic and the Mayo Clinic Sports Medicine team, and individual batch testing for purity and potency.
