The product is formulated by Pure Encapsulations which claims to manufacture hypo-allergenic supplements, free of artificial flavors or other preservatives that could interfere with effectiveness of their products. The company has several products involved in clinical trials.
This formula is advertised as containing a standardized extract of Phosphatidylserine, supporting mental performance, cognition and mental acuity (alertness, reaction time).

PS 100 Ingredients
PS 100 contains the following ingredient: Phosphatidylserine 100 mg.
Phosphatidylserine is a phospholipid found in all cell membranes. Research so far, although inconclusive, has revealed beneficial effects on reducing the risk of dementia and cognitive decline. However, studies are in their preliminary stages and therefore limited. The Phosphatidylserine initially used was extracted from bovine brain, but due to the danger of disease transmission, a soybeans based extract is now used.
This product also contains hypo-allergenic plant fiber derived from pine cellulose as it is a vegetarian product. Although no side effects are listed by the manufacturer, the formula is not recommended for pregnant and/or lactating women without the consent of a physician.
Furthermore, side effects such as insomnia and stomach upset have been reported for doses over 300mg of Phosphatidylserine based supplements. No unwanted effects have been identified from the formula’s interaction with other medication.
The recommendations of use are 3 capsules per day, with meals, taken as individual doses.
