As we age, the nutrient choline becomes less bioavailable, with serious consequences for memory function. Memory Upgrade III is a great-tasting, natural, fruit-flavored citrus cooler containing choline and essential nutrient cofactors plus the important amino acid taurine. Memory Upgrade III makes it easy to ensure adequate levels of choline. This Designer Food® nutritional supplement was designed by life extension scientists Durk Pearson & Sandy Shaw®. Some of the choline in your diet is used by your brain and motor nerves to make the neurotransmitter acetylcholine, which is critical for proper memory function and muscle tone.* Taurine is a brain food that provides your brain with a vital nutrient needed for proper function.* Use Memory Upgrade III to help preserve and protect your memory function.*
