Phosphatidylserine Flashcards
What is Phosphatidylserine (PS) and its role in the brain?
PS is the most abundant fat-soluble phospholipid in the human brain, crucial for neuronal membrane functions, including cell communication, secretory vesicle release, and growth regulation.
Which foods are sources of Phosphatidylserine (PS)?
Food sources include white beans, whole grain barley, carrots, mackerel, herring, and organ meats.
What is the effect of Phosphatidylserine (PS) in Alzheimer’s disease?
PS improves neuronal membrane function, increases neurotransmitters like acetylcholine, and helps preserve glucose metabolism, enhancing cognitive function and memory, especially in patients with less severe symptoms.
Dosage: 300 mg daily or 100 mg three times a day.
How does Phosphatidylserine (PS) help with depression?
PS improves mood by regulating cortisol levels.
Dosage: 100 mg three times a day, more effective when combined with fish oil.
How does Phosphatidylserine (PS) help with ADHD?
PS promotes attention, reduces symptoms of ADHD, and increases short-term memory.
Dosage: 200 mg daily.
How does Phosphatidylserine (PS) help with stress and insomnia?
PS reduces cortisol secretion effects, improving sleep quality and reducing anxiety.
Dosage for insomnia: 400 mg before bed. Dosage for stress: 200 mg daily.
What are the safety and interaction considerations for Phosphatidylserine (PS)?
PS is generally safe for up to six months. It may have additive effects when combined with cholinergic drugs and may reduce the effectiveness of anticholinergic drugs.
