xtension IQ™ helps promote clarity of thinking, sharp focus and excellent memory. Our premier brain formula works in two ways. First, it promotes healthy levels of acetylcholine, a key neurotransmitter, by providing important nutrients such as choline, DMAE and huperzine-A. Second, the vinpocetine and Ginkgo biloba in Extension IQ™ support cerebral microcirculation. With optimal microcirculation, nutrients and oxygen are more effectively carried into the brain cells. Better brain cell nourishment enhances cognitive performance and helps support cellular health. Supporting ingredients such as pyroglutamic acid and L-Phenylalanine also contribute to cognitive function and memory.
