High dose supplementation of zinc induces specific zinc deficiency in hippocampus, which further impair learning and memory due to decreased availability of synaptic zinc and BDNF deficit (Fig. 6). Thus, zinc supplement users should take caution to avoid the overuse of zinc supplementation.31 Jan 2013
How does zinc affect memory?
Zinc plays a key role in regulation of neuronal glutamate signaling, suggesting a possible link between zinc and memory processes. Consistent with this, zinc deficiency causes cognitive impairments in children.
