The Primary active ingredient is: Phosphatidylserine

Phosphatidylserine is a phospholipid that helps support the structure and flexibility of brain cell membranes. This form is usually sourced from soy and used to contribute to neuronal membrane integrity.

This formulation uses a soy-derived phosphatidylserine, a plant-based option commonly used in supplements to support brain health and cognitive function.

What Exactly Does Phosphatidylserine Do?

Phosphatidylserine plays a role in maintaining membrane function which is important for cognitive processes involved in memory and focus. Scientific research suggests memory and cognitive benefits in older adults when PS is taken regularly.

Dr. Kato-Kataoka of a university found that phosphatidylserine supplementation may help support cognitive function in aging populations, consistent with the nutrient’s role in neuronal membrane integrity and neurotransmitter activity.
