Natrol Cognium keeps your mind sharp and your memory strong. It features the #1 most studied ingredient

for memory among leading brain health supplements. In fact, multiple clinical studies have shown statistically

significant improvements in memory and recall in healthy adults, in as a little as four weeks. Cognium is

powered by a silk protein hydrolysate, which is found in the threads of silkworm cocoons. A brain imaging

study indicates that it energizes the brain by increasing blood flow and glucose uptake in the brain’s

centers for learning and memory (results were based on 200 mg taken twice daily). An in vitro study

suggests that Cognium additionally acts like an antioxidant for the brain, shielding it from free

radicals and oxidative stress that help age the brain. Cognium is safe and stimulant free.
