American Ginseng (Cereboost™)


American Ginseng


Supports brain health and cognitive performance*

Supports adaptation to stress *

Supports mood*


Panax quinquefolius is commonly called American ginseng, because it is native to forested regions in North America. It is the same genus as Asian ginseng (Panax ginseng) and prized for many of the same reasons. Both American and Asian ginseng contain similar active constituents called ginsenosides. The ginsenosides are thought to be responsible for many of the adaptogenic (i.e., stress and fatigue support)  and health-promoting properties associated with ginseng.[1] While there are many different ginsenosides, the most well characterized include Rb1, Rb2, Rg1, Rc, Rd, and Re. Cereboost™ is a clinically studied and standardized American ginseng root extract. In humans studies, Cereboost™ has enhanced working memory and alertness, while promoting calmness.*


Cereboost™ has been used in human clinical studies, where it has enhanced alertness, working memory, and calmness.

Cereboost™ was granted the NutrAward 2010 for the Best New Ingredient of the year.

Cereboost™ is produced by Naturex, an innovator in nutraceutical products in Europe and the United States.

Cereboost™ is standardized for total ginsenoside content (10-12%), and several specific ginsenosides, including Rb1 (4-7%), Rb2 (0.2-1.5%), Rg1 (0.1-0.4%), Rc (0.5-3.5%), Rd (0.9-3.0%), and Re (0.4-3.5%). 

Cereboost™ is non-GMO, gluten-free, and vegan.

We consider Panax quinquefolius to be in the adaptogenic herb category; following hormetic dosing principles (see Qualia Dosing Principles) with a high likelihood of having a hormetic range (i.e., a dosing range below and above which results could be poorer). We have selected to dose this at an amount that is consistent with the studied amount in the human clinical studies for supporting working memory, alertness, and calmness.*
