Cognizin (Citicoline) for Sharp and Sound Brain

Cognizin is a trademarked nutrient that is an enhanced form of citicoline. The latter is a naturally occurring chemical in the human body that plays a role in maintaining brain health and function.

This clinically-proven form of citicoline is primarily used as a dietary supplement to help support focus and memory.

Cognizin is made and distributed by Kyowa Hakko USA, and it can be found in many over-the-counter nootropics and brain health supplements.


These are the main benefits that can be achieved by taking Cognizin on a daily basis:

  • Improves brain function and activity.
  • Enhances ability to stay mentally focused.
  • Enhances memory.
  • Supports energy production in brain cells.

How Effective is it?

Clinical studies showed that Cognizin was significantly more effective than placebo in increasing brain energy, focus and attention after about a month of daily supplementation.

It is normal for results to vary for each individual, and while some consumers may notice satisfactory improvement, others may not have success with this supplement.

What is the Typical Dosage?

The manufacturer-recommended dosage is 250mg to 500mg daily. Normally, you should start with a 250mg dose per day and increase it in case you experience no change. You should not consume more than 500mg in a 24 hour period.

What are the Side Effects?

Cognizin is a safe and well-tolerated nutrient that does not have any remarkable side effects. In some clinical studies, doses as high as 2,000mg of citicoline were safely used.

In rare cases, some users may suffer from nausea, stomach pain, and diarrhea when taking higher doses.
