End date November 2016
Trial size 60 participants
Trial identifier NCT02913287, YN001


The aim of the overall project is to investigate the potential of a combination of commercially available nutraceuticals produced by Marigot Ltd (natural seawater derived mineral-rich AquaminMG and seaweed-derived mineral-rich food supplement AquaminTM (FDA GRAS 000028) isolated from Lithothamnion species), as safe and effective supplements to promote cognition in the aged brain.
