CHATSWORTH, Calif. — Natrol LLC has launched Natrol Cognium, a brain health supplement formulated to help improve memory and cognition.

Natrol said Monday that the product, which is backed by nine human clinical studies, has shown statistically significant improvements in memory and cognition in as little as four weeks.

Available in a 60-tablet bottle, Natrol Cognium is now available at retailers nationwide, including Walmart, Rite Aid, Kroger, Vitamin Shoppe and others, as well as at Natrol.com.

Natrol Cognium’s active ingredient is Cera-Q, a silk protein with a unique structure that makes it particularly effective in supporting the brain. Cera-Q is round in the threads of silkworm cocoons. The protein works by energizing and protecting the brain and has been used safely in Eastern medicine for hundreds of years.

Natrol noted that the protein in the supplement has been shown in clinical imaging to increase glucose, providing energy and nourishment for improved brain functioning. It also acts as an antioxidant for the brain, protecting it from free radicals and oxidation that cause aging.

“We’re proud to launch Natrol Cognium as our innovative way to tackle the issues surrounding brain health,” stated Tom Zimmerman, chief executive officer of Natrol. “From forgetting names of friends or colleagues to struggling for a word, we all have those moments where we could use something to keep our memory strong and our minds sharp. People can use Natrol Cognium to proactively manage and own their everyday health and help them face real issues they’re dealing with in their busy lifestyles as they age.”

In announcing Natrol Cognium, Natrol said the product can help with such moments of forgetfulness as walking into a room and not remembering why, searching for your glasses when they’re on top of your head and not remembering your morning coffee, as well as overall brain health.

“People take supplements to help take care of their heart and digestion, so it only makes sense they would look for something to help improve their brain health. In fact, brain health isn’t just something that’s on the mind of baby boomers; I get questions about it from people of all ages,” commented Dr. Mike Dow, author of “The Brain Fog Fix,” a New York Times best-seller. “There are many things that people can do to improve their health, and one of those things can be taking Natrol Cognium, which is safe, natural and stimulant-free.”
