Some caffeinated beverages may benefit people with fatigue

In a recent study from Clarkson University, scientists found that adaptogenic-rich caffeinated beverages are much more helpful than synthetically sourced caffeinated beverages for people with low mental energy or high mental or physical fatigue.

Adaptogens are nontoxic substances, like herbs, mushrooms, or plant extracts, thought to have health benefits and increase the body’s resistance to damage from stress.

The team previously found that the personality trait of energy and fatigue influenced how someone responded to a caffeinated beverage.

Since then, they have also reported how these traits are associated with how people respond to several other interventions, such as exercise, sleep, and even standing desks versus sitting desks.

They also found that there may be a distinct gut microbiome associated with these personality traits, which may influence how certain foods/beverages are metabolized.

In the study, researchers compared an adaptogenic-rich caffeinated beverage, made from green tea and yerba mate to a synthetically sourced caffeinated beverage.

They found that an adaptogenic-rich caffeinated beverage was much more helpful for people who normally report feeling low mental energy or high mental fatigue or high physical fatigue.

These same people reported increased heart rate, increased blood pressure and increased feelings of anxiety with a synthetically sourced caffeinated beverage.

The findings suggest that people who might need caffeine the most (those who normally report feeling low energy/high fatigue) might benefit from consuming an adaptogenic-rich caffeinated beverage, as it seemed to provide the mood benefits without the usual negatively associated responses to caffeine.
