| Phosphatidylserine |
| Description: Phosphatidylserine (PS) is a fat-soluble substance from a class called phospholipids. Phospholipids are necessary components of cell membranes. PS is found in high concentrations in the brain, and may be needed to support mental function.1 Phosphatidylserine works together with other phospholipids to build cell membranes. PS is found in small amounts in normal diet, usually only in the minute bit present in lecithin. Adults over age 50 are most likely to show a deficiency. Phosphatidylserine appears to increase the number of neurotransmitter receptor sites in the brain. Taken in doses of 100 mg three times daily, it has been shown to help improve mental function in Alzheimer’s patients.2 In studies, women taking PS showed 60% less depression than those taking a placebo.3 Natural Sources: May be present in Soy. Useful in treatment of: Alzheimer’s Disease, depression. Recommended Dosage: 100 mg three times daily. Contraindications: None. References: 1Crook TH, Tinklenberg J, Yesavage J, et al.
