The Active Ingredient Is: Phosphatidylserine (from Soy)

Phosphatidylserine is a phospholipid that plays a structural role in cell membranes, particularly in brain tissue.

This form is typically sourced from non-GMO soy lecithin and formulated as a phospholipid complex to support stability and absorption.

What Does Phosphatidylserine Do?

Phosphatidylserine is involved in brain cell membrane function and neurotransmitter activity, with research suggesting benefits for memory and stress management in adults. This information aligns with EFSA and NHS-style function descriptions, and is supported by clinical observations in adults. Dr. Kidd of the University of California found that phosphatidylserine may support memory performance and stress responses.

It is also linked to a role in supporting cognitive function and mood regulation in response to everyday stress, contributing to normal brain function.
