Memory-Plus is from the "Blue Collection", which is an exclusive group of products formulated by our founder Mike Minarsich. "there has been a lot more research on nutrition at the cellular level over the last few years", says Mike, "I have used that information in choosing nutrients that work synergistically together." The result is a formula specific to the need. Memory-Plus started with phosphatidylserine because it has so much research regarding its impact on brain cells. Then the rest of the formula fell into place. All the nutrients working together toward a common goal. Which is to sustain the quality of life as we age.
