Phosphatidylserine is a safe, plant-based nutritional supplement extracted from high-concentration lecithin that is derived from carefully selected soybean. Every 100 kilograms of soy bean lecithin yields only about 0.5 kilograms of phosphatidylserine, making it a valuable ingredient.

Scientific literature indicates that phosphatidylserine:

1. Improves symptoms for women with premenstrual syndrome (PMS), including promoting emotional tranquility, soothing mood fluctuations, and alleviating physical discomfort
2. Significantly improves mood and cognition in elderly subjects and supports emotional stability

1. The maximum daily intake is limited to 500mg
2. The phosphatidylserine content must be 90% or less.
3. The source must be from extraction of soybeans or from the synthesis of soybean lecithin and serine
