SerinAid® (Phosphatidylserine — Chemi Nutra)

Evidence Level
Strong
1 Clinical Trial
3 Documented Benefits
4/5 Evidence Score

SerinAid® is a branded phosphatidylserine (PS) from Chemi Nutra, a phospholipid that is a major structural component of brain cell membranes. Soy- and sunflower-derived PS is studied for supporting memory and cognition, and for blunting the cortisol response to stress and exercise.

Studied Dose 100 to 300 mg per day; 300 mg/day is common in cognition studies.
Active Compound Phosphatidylserine (PS), a membrane phospholipid derived from soy or sunflower lecithin, concentrated in neuronal membranes.

Benefits

Memory and cognition

Phosphatidylserine supplementation has supported memory and cognitive function in controlled studies, particularly in older adults and people with age-related memory complaints.

Supported by Trial 1

Stress and cortisol

PS is studied for moderating the cortisol response to mental and physical stress, supporting a calmer response under pressure.

Supported by Trial 1

Brain cell membranes

As a core membrane phospholipid, PS supports the fluidity and signaling of neuronal membranes that underlie learning and memory.

Supported by Trial 1

Mechanism of action

1

Membrane phospholipid

PS is enriched in the inner layer of neuronal membranes, where it supports receptor function, neurotransmitter release, and overall membrane health.

2

HPA-axis modulation

PS appears to dampen excessive activation of the stress (HPA) axis, lowering the cortisol surge after stressors.

Clinical trials

1
Phosphatidylserine and Cognition — RCT
PubMed

Randomized, placebo-controlled trial of supplementation with sunflower-derived phosphatidylserine on cognitive outcomes. (Friling et al. 2025, Nutrition Journal)

Adults.

Phosphatidylserine supplementation supported cognitive performance versus placebo, consistent with its established memory and stress benefits.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated — mild digestive upset or insomnia is occasionally reported.
Taking it earlier in the day avoids any sleep disturbance.
Soy-derived PS may concern those with soy allergy; sunflower PS is an alternative.

Important Drug interactions

Anticoagulants and antiplatelets — theoretical additive effect; monitor.
Acetylcholinesterase inhibitors — possible additive cognitive effect.
Tell your doctor if you take medication for memory or mood.
