Neuropeptide dietary supplement N-PEP-12 enhances cognitive function and activates brain bioelectrical activity in healthy elderly subjects.

N-PEP-12 is a dietary supplement consisting of neuropeptides and amino acids. In animal experiments, the compound has been shown to enhance cognitive function and reduce neurodegenerative events associated with aging. In this study, we investigated the effects of a single oral dose of N-PEP-12 (180 mg) on brain bioelectrical activity and cognitive performance in healthy elderly subjects. N-PEP-12 induced a significant (p < 0.05) increase in relative α-activity power 6 h after administration. This enhancement was accompanied by a generalized decrease in slow Δ-activity. Significant improvement in memory performance subtests was also seen 6 h after N-PEP-12 administration in some hut not in all rests. Taken together, these data suggest that N-PEP-12 might he a reliable dietary supplement to he investigated for improving and, perhaps, maintaining brain function among healthy older adults.
