The Active Ingredient Is: Phosphatidylserine

Phosphatidylserine is essentially a phospholipid that helps make up part of neuronal cell membranes and plays a role in cell signalling and neurotransmitter activity. It’s a nutrient used to support normal brain function and cognitive processes.

This form comes from soy lecithin and is supplied as phosphatidylserine-containing material from a soy source. Soy-derived phosphatidylserine is a recognised, structured ingredient that helps support membrane function and neuronal communication.

What Does Phosphatidylserine Do?

Phosphatidylserine helps maintain cell membrane fluidity and is involved in signalling between brain cells, supporting normal memory and learning processes. It plays a part in neurotransmitter production and helps balance stress-related cortisol levels, contributing to normal cognitive function.

EFSA and related scientific discussions recognise the role of phosphatidylserine in normal brain function, aligning with its proposed mechanism in supporting cognitive health without implying disease treatment.

This supplement isn't meant to diagnose, treat, cure, or prevent any disease.
