Memory Protect combines a unique colostrinin polypeptide complex with the trace mineral lithium for unrivaled memory and cognitive health support for the aging brain. Colostrinin supports cognition, memory, and also inhibits inflammatory factors in the brain which can lead to reduced cognitive function and memory loss. And research now shows that lithium helps inhibit an enzyme sometimes associated with cognitive decline, as well as providing benefits for longevity and mood. Harness the power of Memory Protect and help maintain your brain!

Amyloid beta (or abeta) are “misfolded” proteins which are quickly and efficiently cleared from a youthful, healthy brain through natural processes. But as we age, these proteins begin to accumulate, affecting memory and cognitive function. Plus, abeta can chemically affect tau proteins, cellular components responsible for moving essential molecules throughout the cell.

Memory Protect’s Colostrinin polypeptide complex promotes cognition, memory, and helps inhibit inflammatory factors in the brain. Colostrinin also favorably affects gene expression associated with abeta protein production,1 encourages production of enzymes which support the natural breakdown of abeta proteins,1 and encouraged learning and memory in animal studies — along with increasing median life-span by 26%.2

Laboratory studies demonstrate that colostrinin favorably altered the gene expression of cells in culture to those produced by natural nerve growth factor, promoting differentiation of primitive cells into functioning adult neuron cells, and encouraging healthy neurite growth — tiny structures essential for cell-to-cell communication.3,4

Memory Protect also delivers lithium, which has long been used to promote healthy mood.5 But now, research indicates that lithium helps inhibit the GSK3 enzyme, which affects tau protein phosphorylation.6 Phosphorylated tau proteins can contribute to age-related cognitive decline and memory health.

Inhibiting GSK3 may help maintain healthy glucose levels already within normal range in the brain.7,8 Lithium also promotes autophagy, the healthy breakdown of tau and abeta proteins through natural processes.5 And in animal studies, lithium helped maintain memory health and cognitive performance.9

So don’t wait to maintain your brain. Choose Memory Protect, a memory and cognitive health support supplement made with powerful, brain-friendly ingredients — only from Life Extension!
