PS 150 (Phosphatidylserine 150mg) - 60 capsules

Improved soy-free with increased potency

Designs for Health is using non-soy, sunflower sourced phosphatidyl serine per one capsule serving of 150mg.

Phosphatidyl serine (PS) is a nutrient essential for optimal brain function. Because PS is crucial for the overall health of brain cells, research on PS has shown that it benefits a wide range of brain activities such as mental focus, memory recall, and performance on tasks. There are no foods rich in PS, except for brain, so PS supplementation is the only way to increase your levels of this valuable brain nutrient. PS is an essential component of all neuronal membranes. Human research suggests that PS may help support overall brain wellness. 

Benefits of Phosphatidyl Serine

• Can help improve mental focus
• Reduces cortisol levels for stress management
• May help relieve depression
• Can improve quality of life in Alzheimer's cases
• Helps slow age-related memory deterioration 
• Helpful with emotional, mental and physical stress

Are there any nutrients that help PS work more effectively? 
Acetyl-L-carnitine, vitamins C and E, B vitamins, magnesium, selenium, and NADH all increase the effectiveness of PS. 

Memory and Recall 
Memories are formed when a group of brain cells-neurons-talk to each other. Together, neurons create a memory of an event, such as where the keys are, where you put the remote control, or where you parked the car. In order for memories to be both formed and recalled, neurons must talk to each other. Without PS, such communication among neurons is difficult if not impossible. With PS, neurons communicate more effectively. That is why PS has such positive effects on memory, recall, and overall brain function. 

Helping Age Related Memory Loss 
As we age, most of us lose some memory function. PS may help to reverse or slow this process.2 Seventy-five patients with age-related memory impairment were given 300 mg of PS per day for 12 weeks. PS led to improved performance tests related to learning and memory tasks of daily life.3 Another study of thirty-three patients with dementia showed equally promising results. This 8-week study of 300 mg per day of PS showed that PS can significantly improve overall brain wellness in those with dementia.4 

Slowing Alzheimer's Disease 
Alzheimer's disease is a debilitating ailment that destroys the memory of older adults. While there is no cure for Alzheimer's, nutrients like PS may help slow the progression and even reverse some of the symptoms of this disease.5-7 Eighteen patients with Alzheimer's disease given 400 mg of PS per day for 6 months experienced a wide range of positive effects on memory and recall.8 Twenty-five patients with Alzheimer's disease given 300 mg of PS for 12 weeks also saw improvements in brain function. This study also showed that PS may have the most benefit when given in early stages of Alzheimer's disease.9 

Relieving Depression 
The effects of phosphatidyl serine on cognitive, affective and behavioral symptoms were studied in a group of 10 elderly women with depressive disorders. Patients were treated with placebo for 15 days, followed by PS at 300mg/ day for 30 days. PS induced consistent improvement of depressive symptoms, memory and behavior.l0 

PS and hormones
Research shows that phosphatidylserine helps normalize cortisol levels when the body is under stress. Studies have been performed using exercise as a means of producing stress, as exercise-induced stress can trigger an excessive cortisol response. The studies’ results demonstrated that PS promotes healthy hormone levels by reducing the cortisol response to acute exercise-induced stress.11,12 Thus, PS is effective at combating this stress, helping to stave off the negative effects that accompany too much exercise, such as substandard performance, potential injury, and even a lowered immune response.13
