How to Use It
Positive effects on mental function have been achieved using 200–500 mg per day of bovine PS; most studies used 300 mg per day. Preliminary animal research shows that the soy-derived PS does have effects on brain function similar to effects from the bovine source. 23, 24, 25
Where to Find It
PS is found in only trace amounts in a typical diet. Very small amounts are present in lecithin. The body manufactures PS from phospholipid building blocks. PS research has used material derived from a bovine source. Currently, PS that is commercially available is derived from soy.
PS is not an essential nutrient, and therefore dietary deficiencies do not occur. Adults age 50 and older, especially those with age-related cognitive decline, may not synthesize enough PS, and appear most likely to benefit from supplemental PS.
