Phosphatidylserine

Key Benefits

• Provides 300 mg phosphatidylserine per serving.

• Derived from sunflower as a plant-based source.

• Free from dairy, gluten, soy, and common allergens.

Phosphatidylserine delivers 300 mg per serving from a sunflower-derived source, presented in a two-capsule daily format. This phospholipid forms part of the structure of cell membranes and is naturally found throughout the body, with higher concentrations in certain tissues.

Sourced from sunflower rather than soy, this formulation offers a plant-based alternative suitable for those avoiding common allergens. Each serving is encapsulated in a vegetable capsule with minimal additional ingredients, keeping the formulation simple and focused.

Free from dairy, gluten, soy, wheat, fish, shellfish, tree nuts, and peanuts, it provides a clean-label option aligned with a wide range of dietary preferences.

Phosphatidylserine from ProHealth uses a sunflower-derived source rather than soy, which many products on the market rely on. Sunflower phosphatidylserine often suits those who avoid soy or have sensitivities, and it avoids concerns linked to genetically modified soy crops. The product is manufactured in an FDA-registered, GMP-certified facility, which supports consistent production standards. Each batch also undergoes third-party testing in US laboratories to verify quality, purity, and potency. This careful sourcing and testing process gives you a more considered and dependable phosphatidylserine option for daily use.
