Phosphatidylserine
Also known as: PS, Phosphatidyl Serine, Lipid Compound
Phosphatidylserine (PS) is a naturally occurring phospholipid that is a crucial structural component of cell membranes, particularly concentrated in brain cell membranes. This compound plays vital roles in cell signaling, healthy cognitive function, and stress response. Derived from plant sources or synthesized, Phosphatidylserine has been extensively researched for supporting memory, cognitive function, and healthy stress management in aging populations.
Benefits
Well-researched for supporting memory function, recall, and cognitive performance, with numerous clinical studies showing improvements in memory and learning ability. Supports healthy stress response and cortisol regulation, helping the body manage mental and physical stress more effectively. May promote emotional well-being and healthy mood through its effects on neurotransmitters and neural function. Supports healthy brain aging and may help maintain cognitive function in older adults. May enhance focus, concentration, and mental clarity.
Recommended Dosage
Typical dosage ranges from 100 to 300 mg daily, with most clinical studies using 100 mg three times daily (300 mg total) for memory and cognitive support. Some studies have used doses as low as 100-200 mg daily and found benefits. Effects typically develop over 4-8 weeks of consistent use, with maximum benefits noted at 12 weeks. Phosphatidylserine is best absorbed when taken with meals containing fat.
Food Sources
Phosphatidylserine is present in small amounts in soy lecithin, organ meats (particularly brain), fish, and egg yolks, but in very low concentrations. Obtaining therapeutic doses through diet would require consuming impractically large quantities of these foods. Most supplements are derived from soy lecithin through extraction processes or are synthesized. Bioavailability from supplements is typically superior to food sources.
Side Effects
Generally very well-tolerated with minimal side effects at recommended doses. Some users experience mild gastrointestinal symptoms including mild nausea, stomach upset, or diarrhea. Insomnia or sleep disturbances may occur in some individuals, particularly if taken in the evening. Dizziness or headaches have been reported rarely. Very high doses may cause mild overstimulation of the nervous system.
Interactions
Phosphatidylserine does not typically interact significantly with medications. However, those taking anticoagulant or antiplatelet medications (blood thinners) should consult healthcare providers due to potential mild blood-thinning effects. Safe to combine with most cognitive-supporting supplements and medications. May theoretically enhance effects of CNS-active medications, though clinically significant interaction is unlikely.
Warnings
Not recommended for individuals with blood clotting disorders or those taking anticoagulant medications without medical guidance. Pregnancy and breastfeeding safety has not been fully established, so use is not recommended in these populations without professional guidance. Those taking anticoagulant medications should consult healthcare providers before supplementing. Some individuals may experience mild overstimulation or sleep disturbances.
Deficiency Symptoms
Phosphatidylserine is not technically deficient, as the body produces it, but inadequate dietary intake and reduced production with aging may contribute to memory decline and cognitive aging. The compound has been researched specifically for its ability to support healthy memory and cognitive function in aging populations.

Vitamins
Vitamin D is a fat-soluble vitamin that plays a crucial role in calcium absorption, bone health, immune function, and mood regulation. Unlike most vitamins, your body can produce vitamin D when your skin is exposed to sunlight, earning it the nickname 'the sunshine vitamin.'
Vitamin C
Vitamins
Vitamin C is a water-soluble vitamin and powerful antioxidant that the human body cannot produce on its own. It is essential for the growth, development, and repair of all body tissues and plays a role in many body functions including immune defense, collagen formation, and iron absorption.

Fatty Acids
Omega-3 fatty acids are essential polyunsaturated fats that your body cannot make on its own. The two most important omega-3s found in fish oil are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). They play critical roles in brain function, heart health, and reducing inflammation throughout the body.
