Researchers from Northumbria University (England), PHMR Ltd (England), and PepsiCo (USA) report that the chlorogenic acid-rich coffee berry supplementation also led to self-reported increases in vigour/activity and decreases in fatigue/inertia.
“… 1100 mg coffee berry extract, administered in isolation, was associated with a clear pattern of beneficial effects on subjective alertness and overall mood,” wrote the researchers in Nutritional Neuroscience.
“These results replicate and build upon the effects of the same dose of coffee berry reported recently by our lab, which suggests that these effects are robust.”
The study was funded by PepsiCo.
Study details
The new randomized, double-blind, placebo-controlled, crossover study included 46 healthy men and women with an average age of 23. On four separate occasions, the participants were assigned to one of four groups: 1,100 mg coffee berry extract; 1,100 mg coffee berry extract plus 275 mg apple extract; 100 mg coffee berry extract plus 275 mg apple extract; or placebo. Cognitive and mood assessments were performed before consuming the interventions, and again after one, three, and six hours after the dose.
The results showed that the 1,100 mg coffee berry extract consistently improved alertness, with the participants also reporting increases in increased vigour/activity. Decreases in fatigue/inertia and overall negative mood were also reported following 1,100 mg of coffee berry extract.
“Importantly, all these results were main effects of treatment indicating that the beneficial effect was consistently observed up until 6 h post treatment,” stated the researchers.
