PS 150 Phosphatidylserine - BRAIN HEALTH
Phosphatidylserine (PS) is a key phospholipid in cell and mitochondrial membranes—especially concentrated in the brain (≈15% of cortical phospholipids). PS helps regulate neuronal signaling, synapse formation, and neurotransmitter function. Endogenous PS synthesis declines with age and dietary sources are minimal, so supplementation can help maintain healthy brain levels.
What it does:
• Supports mental focus, working memory, and overall cognitive function
• Helps maintain healthy cortisol responses to psychological and exercise-induced stress
• Promotes a stable mood and healthy stress resilience
• May support quality of life in age-related cognitive decline when used as part of a comprehensive program
Research snapshot:
• Most human studies on brain/cognitive support used 300 mg PS/day; maintenance intakes of 100–200 mg/day may be sufficient for many adults.
• In older adults with memory complaints, PS has shown improvements in everyday memory and cognition.
• In high-stress settings and after exercise, PS can help normalize cortisol responses and support a favorable testosterone:cortisol balance.
• In Alzheimer’s disease, small studies show modest, short-term benefits on function and recall; PS is best considered adjunctive, not standalone.
• DHA (from fish oil) complements PS by supporting membrane structure and PS accumulation in neuronal membranes.
Benefits:
• Supports mental focus and memory
• Helps maintain healthy cortisol metabolism under stress
• Promotes a healthy mood
• Supports cognitive function in aging
Highlights:
• 150 mg PS per capsule (from Helianthus annuus seed; sunflower-derived)
• Designed to support brain cell membrane integrity and signaling
• Pairs well with DHA-rich omega-3 (e.g., OmegAvail™ Ultra DHA)
Recommended dose:
Adults: Take 2 capsules per day (300 mg total), or as directed by your health-care practitioner. Dosing recommendations reflect typical use for an average 150-lb healthy adult; practitioners may individualize based on goals, body weight, history, and concurrent therapies.
Ingredients (per capsule):
• Phosphatidylserine (sunflower seed) — 150 mg
Non-medicinal ingredients: Microcrystalline cellulose, hypromellose (capsule), silicon dioxide, magnesium stearate (vegetable source).
Notes & cautions:
• If using for a medical condition or taking medications—especially psychotropic agents—use under professional supervision.
• Consider co-supplementing with DHA to support membrane health and PS function.
• Consult your health-care practitioner about your specific circumstances and any questions you have.
