Brain and Nervous System Health Dietary Supplement Supports Healthy Mental Function Helps Maintain Cell Signaling and Integrity in The Brain Helps Maintain Healthy Memory and Cognitive Function Science-Backed Quality Since 1969 Sharp-PS® Give your brain a healthy boost with Swanson Sunflower Phosphatidylserine Soy Free. Phosphatidylserine (PS) is a popular, fat-soluble amino acid derivative compound that millions of people use to nourish and support healthy cognitive function. This phospholipid is a vital component of cell membranes (particularly within the brain), where it is essential for healthy neurotransmitter function. While the vast majority of phosphatidylserine supplements on the market tend to be derived from soy, our eco-friendly sunflower phosphatidylserine eliminates this concern with 100% soy-free Sharp-PS® Green phosphatidylserine. As we look to protect our health as we age, brain health is a key concern. Phosphatidylserine is an important building block for multiple facets of brain health such as neurogenesis, brain plasticity and the formation of the myelin sheath that protects nerve cells and allows for cellular signaling. Supplementing with phosphatidylserine contributes to overall cellular health, but specifically the health of cells in the brain, helping to maintain mental sharpness.

Deep sleep

I’ve experienced sleep challenges since menopause. I’ve tried everything but consistency was an issue. This is the first supplement that has work consistently, deep sleep, calmed racing thoughts, and if I do wake I can fall off to sleep easily without next day hangover. Works to lower my cortisol. I choose this product because it is soy free.

For getting deep sleep at night

Phosphatidylserine especially sunflower derived one is good for getting deep sleep at night due to the cortisol blocking effect. Memory improvements if happen may be due to the result of sleep improvement. Thus, you can experience sleep improvement at first and memory improvement after trying it for longer periods.
