As we age, our mental acuity naturally declines. Take steps now to help stay mentally sharp tomorrow. NUTRILITE? MEMORY BUILDERTM dietary supplement contains a unique and complementary combination of standardized extracts of Ginkgo biloba and Cistanche tubulosa. Research suggests Ginkgo biloba provides quick support for mental performance, 4-6 hours after taking, while preliminary research shows that daily intake of 300 mg of Nutrilite's standardized Cistanche tubulosa may improve memory, focus, and recall over a longer period of time, or a period of weeks. The key phytonutrients contained within Ginkgo biloba extract helps to protect and nourish the brain through its ability to provide antioxidant protection and improve blood flow to the brain. Research suggests that a serving of Ginkgo extract in MEMORY BUILDER can help support clearer thinking shortly after taking, for 4-6 hours afterward.
