2) History of Cognium

Natrol was founded in 1980 by Elliott Balbert, and it initially started as a cosmetics company[1]. Over the past decades, the company has grown into one of the most recognized name brands in the vitamin, mineral, and supplement categories.

"I have just completed my first bottle of Cognium, and I haven't noticed a significant difference in my ability to concentrate or remember things. I had much better results with Moon Juice Brain Dust which I would put into my morning smoothie. I purchased two bottles of Cognium. I will complete the second bottle, but if I don't feel a difference at the end of the bottle, I will return to my trusty Brain Dust." [Read full review]

I haven’t done any before and after tests to see whether Cognium helps with my memory, but the biggest difference I have noticed is it really helps with my night vision! And I’m pretty sure it is the cognium, because whenever I forget to take it, my night vision suffers.
