A breakthrough in brain health, Natrol® Cognium® is powered by a unique ingredient supported by human clinical studies that show statistically significant improvements in memory and recall in healthy adults, in as little as four weeks.†

Product Description

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, several 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.†

  • Results in as little as 4 weeks
Support your brain with Cognium®, the smart choice in brain health†
