The Active Ingredient Is: Phosphatidylserine (Sunflower-Derived)

Phosphatidylserine is a phospholipid that is a structural component of brain cell membranes, contributing to membrane fluidity and cell-to-cell communication.

This form is sunflower-derived and used to support neurochemical balance and membrane function within the brain.

What Does Phosphatidylserine Do?

Phosphatidylserine participates in maintaining neuronal membranes and supports cognitive function, with evidence suggesting it may influence memory-related processes. Research indicates potential improvements in cognitive parameters with supplementation, reinforcing its role in brain health.

Dr Cenacchi of Milano University found that phosphatidylserine can improve certain behavioural and cognitive measures in older adults, providing context for its use as a memory-supporting nutrient.

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