Clinical Trial Summary

The objective of the study is to test the capacity of acute and chronic supplementations of Turmipure GOLD® to improve cognitive performance in healthy aging

Description:

The aim of this clinical study is to determine whether oral administration of Turmipure GOLD® can contribute to the short- and long-term improvement of cognitive functions, including memory and attention, in subjects with age-associated memory impairment.
