Scientific background

Independent research

Phosphatidylserine, lecithin and phospholipids

Phosphatidylserine and other phospholipids are components of cell membranes. Lecithin is a mixture of phospholipids, often from sunflower or soy.

Choline (choline bitartrate, alpha-GPC)

Choline is an essential nutrient used to make cell membranes and the neurotransmitter acetylcholine. EFSA set an adequate intake of 400 mg a day for adults¹. Supplements supply it as choline bitartrate, alpha-GPC or citicoline.

Research evidence

Independent research

Phosphatidylserine, lecithin and phospholipids

A 2026 systematic review concluded that current evidence does not support citicoline or phosphatidylserine compounds as effective cognitive enhancers in mental disorders².

Choline (choline bitartrate, alpha-GPC)

The EU authorises claims that choline contributes to normal lipid metabolism, homocysteine metabolism and liver function for foods that are a source of choline³. Claims that choline improves focus or exercise performance are not authorised.

Evidence limitations

Independent research

This product does not state all ingredient amounts, so the doses used in research cannot be compared with what one serving provides.

The studies summarised in this guide examined single ingredients. No published study has tested this product or this combination of ingredients.

Phosphatidylserine, lecithin and phospholipids

Studies have methodological limitations and a high risk of bias².

Choline (choline bitartrate, alpha-GPC)

Evidence on cognitive or performance effects in healthy adults is limited.
