Phosphatidylserine PS 100 Capsules - Supports Brain Health

Our review of Jarrow Formulas PS 100 focuses on a simple promise: concentrated phosphatidylserine in an easy-to-take capsule for everyday cognitive support. For adults looking to support brain membrane structure and maintain cognitive health without complex dosing or proprietary blends, this supplement delivers a clear single-ingredient approach. The capsules contain a soy-derived, stabilized form of PS at 100 mg per dose and are designed for flexible use up to three times daily with meals, making them practical for users who prefer straightforward, science-informed formulations.

Key Features

• Phosphatidylserine source: Contains a concentrated PS derived from soy lecithin that supports cell membrane integrity in the brain.
• Designed for brain health: Formulated to provide the structural phospholipid important for cognitive function and neuronal membrane support.
• Concentrated form: The Cogni-PS ingredient is stabilized for better shelf life and consistent dosing compared with unstandardized lecithin extracts.
• Flexible dosing: Adults can take 1 capsule up to three times per day with meals, allowing users to tailor daily intake to their needs.
• Science-informed formula: Developed by a brand that emphasizes superior science to create smarter dietary supplements.

Who It's For

Jarrow Formulas PS 100 is well suited for adults seeking a focused phospholipid supplement to support cognitive health and cell membrane structure without extra fillers or complex blends. It appeals to people who prefer a product grounded in research and a brand philosophy of informed formulation.

Those looking for multinutrient cognitive stacks, vegan-labeled PS from non-soy sources, or specific clinical dosing should look elsewhere or consult a healthcare professional, since this product is a single-ingredient, soy-derived PS capsule and dosing is flexible rather than protocol-driven.
