The Active Ingredient Is: Phosphatidylserine (PS)

Phosphatidylserine is essentially a natural phospholipid building block of brain cell membranes, helping a key role in cellular communication and organisation. This product source uses sunflower lecithin to provide a soy-free PS suitable for sensitive dietary needs.

As a brain membrane component, this form supports normal membrane integrity and function, helping keep neuronal signalling and overall brain health.

What Does Phosphatidylserine Do?

Phosphatidylserine supports memory, focus and cognitive health as part of normal brain function. It is involved in neurotransmitter signalling and helps keep membrane stability, with possible antioxidant benefits to support age-related neural integrity.

EFSA-aligned functions include helping with neurotransmitter regulation and maintaining neural communication under normal conditions.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
