Phosphatidylserine

Phosphatidylserine (PS) is a phospholipid naturally present in cell membranes throughout the body, with the highest concentrations found in brain tissue. As a structural component of neuronal membranes, PS supports membrane fluidity and the efficiency of signal transmission between nerve cells. It contributes to the maintenance of normal cognitive and brain function.

PS supplements are derived from either soy lecithin or sunflower lecithin. Our PS is soy-derived, the form used in the majority of clinical research on phosphatidylserine to date, and the source on which the authorised EU health claims are based. While sunflower-derived PS has grown in popularity as an alternative, its human clinical evidence base remains more limited.

A healthy lifestyle should always take priority over supplements.
Get 7 to 9 hours of high-quality sleep daily. Eat leafy greens, cruciferous vegetables, and whole grains, with 1.2 grams of protein per kg of body weight. Stay hydrated. Exercise 30 to 60 minutes a day, combining resistance training, HIIT, and steady-state activity. Manage stress through rest, reflection, and connection with others. Supplements are designed to support this foundation, not replace it.

Do not consume if pregnant or breastfeeding. Do not exceed the recommended dosage. Keep out of reach of children. Store below 25°C in a cool, dry, dark place, with humidity below 40%

• Cognitive function: Contributes to the maintenance of normal cognitive function (an EU-authorised health claim for phosphatidylserine).
• Membrane structure: Supports the fluidity and structural integrity of neuronal cell membranes.
• Nerve signalling: Supports efficient signal transmission between nerve cells.
• Research-backed source: Formulated with soy-derived PS, the form behind the majority of human clinical research on this ingredient to date.
  

Take 1 capsule daily, ideally with food.

Each container contains 60 capsules, a 60-day supply at the recommended dose.

Consistency matters. Clinical studies on PS typically evaluate cognitive benefits after weeks of regular, uninterrupted use.

• In a 15-week randomised controlled trial, 157 older adults with memory complaints took 300 mg a day of phosphatidylserine enriched with omega-3s or a placebo, and the supplement group showed a significant improvement in immediate verbal recall (Vakhapova et al., 2010).
• In a 12-month randomised controlled trial, 190 older adults with early-stage memory decline took a daily supplement providing 63 mg phosphatidylserine alongside 288 mg of a plant omega-3, ginkgo extract and B vitamins, and did better than placebo on arithmetic, verbal reasoning and short-term memory (Duan et al., 2025).
• In a three-week randomised controlled trial, four groups of 20 people took 400, 600 or 800 mg a day of phosphatidylserine as a soy-based complex with phosphatidic acid before a standardised public-speaking stress test, and only the 400 mg group showed a reduced stress hormone response (Hellhammer et al., 2004).
• In a six-week randomised controlled trial, 75 men took 400 mg or 200 mg a day of phosphatidylserine as the same complex, and the 400 mg dose lowered the stress hormone response in men who were already chronically stressed while 200 mg made no difference (Hellhammer et al., 2014).
• In a randomised controlled trial, 40 women with premenstrual syndrome took 400 mg phosphatidylserine with 400 mg phosphatidic acid daily across three cycles and reported greater improvement in overall symptoms than placebo, mainly physical rather than mood symptoms (Schmidt et al., 2018).
