Supplement Combination May Help Improve Working Memory

Supplement Combination May Help Improve Working Memory

Bacopa is a perennial herb that has long been used in Ayurveda, the traditional medicine of India. American ginseng is an herbaceous perennial plant in the ivy family that is commonly used in Chinese medicine. A recent study suggests that a combination of bacopa, American ginseng, and whole coffee fruit extract may help improve working memory.

Forty adults with an average age of 40 participated in the study. Half of them took a supplement containing 300 mg of bacopa, 100 mg of American ginseng, and 100 mg of whole coffee fruit extract. The other half took a placebo. The researchers tested working memory and attention at baseline, and 45 minutes after the participants took the supplement or placebo. They also monitored changes in blood supply to the prefrontal cortex.

Participants who took the supplement saw significant improvements in working memory in terms of accuracy and response time, compared to the placebo group. The supplement group also saw a reduction in prefrontal cortex activation, which suggests increased neural efficiency.

The study was conducted by researchers from Central Queensland University. It was published online ahead of print on November 18, 2019 in the journal Nutritional Neuroscience.
