This scientific paper, titled "Pyrroloquinoline quinone disodium salt improves brain function in both younger and older adults," details a double-blind, placebo-controlled clinical study. The research aimed to evaluate the effects of Pyrroloquinoline quinone disodium salt (PQQ) on cognitive function across a broad age range (20-65 years). The study found that PQQ positively impacted specific cognitive areas, with younger participants showing improvements in cognitive flexibility and executive speed within 8 weeks, while older adults experienced enhancements in composite and verbal memory after 12 weeks. The authors conclude that PQQ serves as a beneficial functional food for improving brain function across all adult age groups.
