Phosphatidylserine 100 mg by Thorne

If you are looking at phosphatidylserine for memory and stress resilience, this 100 mg per capsule format is a flexible building block. It suits adults who want a non-stimulant nutrient to layer alongside sleep, exercise, and steady meals. The manufacturer positions phosphatidylserine as primary phospholipid in brain cell membranes that supports cell-to-cell communication and helps modulate cortisol during stress.

Phosphatidylserine is a phospholipid component of neuronal cell membranes, where receptors and ion channels need to be arranged correctly so signals travel efficiently. By stabilizing these membranes, the manufacturer connects it to memory, focus, and the cortisol axis (the brain-adrenal stress loop). Other mechanisms the manufacturer notes include support for cell metabolism (such as glucose utilization) and neurotransmitter formation, plus antioxidant activity.

Take 1 capsule two to three times daily, as Thorne directs, with food. A common pattern is 1 with breakfast, 1 with lunch, and a third with dinner if you want a higher daily total. Memory and focus support typically uses 200 to 300 mg per day total in research; cortisol modulation work often starts at 200 to 400 mg per day. Take earlier in the day if you are sensitive to alerting effects.

If you take medication that affects acetylcholine signaling, are pregnant or breastfeeding, or have a known soy allergy, talk to your clinician before starting and review the warnings below.
