Cognitive Health With Memorzine Huperzine A, Alpha-GPC & Phosphatidyl Serine Supports Memory, Learning and Alertness A Dietary Supplement Vegetarian/Vegan GMP Quality Assured RememBrain is a formulation that supports mental alertness and learning by promoting proper Acetylcholine (ACh) production and activity. ACh is a neurotransmitter that is necessary for normal neurological and cognitive function, and whose production tends to decrease with age. RememBrain combines Alpha-GPC (a bioavailable form of choline) to promote ACh production with Memorzine Huperzine A to maintain ACh levels in the brain. Phosphatidyl Serine is also included to support healthy membranes and efficient nerve cell signaling.
