More On Phosphatidylserine

Think Young™ could become a key weapon in the battle against mental aging. The chemical compound name of Think Young™ is Phosphatidylserine (PS), a phospholipid found on the surface of membranes in brain cells and synapses (the connection between nerve cells). PS activates protein-kinase C, an important brain enzyme which declines with age; stimulates the production of acetylcholine, a "brain messenger" chemical which helps regulate memory; and increases the activity of protein ion pumps and receptors which facilitate the transmission of information within the nervous system. 

PS also regulates several cell functions including the production and activation of nerve cells and transmitters and the removal of aging cells. These functions are all linked to membrane mechanisms which rely on phospholipids. PS keeps levels of nerve growth factor at optimum levels. Nerve growth factor is largely responsible for the regulation of nerve cell renewal. PS has been shown to have a positive effect on Alzheimer's disease including an improved capacity for self-care, word recall, and memory and learning tasks. In a 1988 Italian study, scientists gave PS to 70 Alzheimer's patients for three months. Memory improved in all patients and the improvement was maintained three months after PS was withdrawn. In a more recent study at the National Institute of Mental Health, 150 otherwise healthy people who suffered from age-related memory impairment showed a 15–20 percent memory improvement, indicating that even healthy people can benefit from the restorative properties of PS. The Institute has described a condition, "Age-Associated Mental Impairment" (AAMI), in healthy persons over 50. It is estimated that AAMI may affect most of the over 50 population. (According to U.S. Census figures there are more than 60 million people over 50.) 

For subjects with non-Alzheimer's cognitive decline (clinical studies have been done with subjects suffering from cerebral arteriosclerosis, Parkinson's, senile dementia and depression), PS led to improved short-term memory, socialization skills, and behavior. PS lowers the production of stress hormones associated with exercise. A recent study showed that PS protected against stress-induced behavioral changes and improved learning and memory in old rats. One of the exciting effects of PS is its positive effect on depression which afflicts millions in the U.S. Subjects showed improvement of depressive symptoms, memory and behavior. 

A daily intake of 200 mg is recommended for maintaining current levels of mental functioning. The suggested therapeutic intake is 400 to 800 mg per day. At this level, it is believed that taking Think Young™ for three months could reverse up to 12 years of mental decline. Combining Think Young™ with Triple Strength Lecithin would provide the benefits of both products including weight management and improvement of circulatory health.
