| Research Abstract |
Some of botanical supplements analyzed contained high concentration of Aluminium (Al) and manganese (Mn). Al and Mn are known to have neurotoxic effects. We investigated the effect of chronic exposure to Al and/or Mn on animal behavior. Chronic exposure to Al or Mn inhibited wheel-running activity in mice. Chronic exposure to Al did not affect the passive avoidance performance, but Mn inhibited avoidance performance in dose-dependent manner in rats. We conducted a questionnaire survey to investigate the use of dietary supplements and dietary habits in adults. Supplement users had more healthy eating habits than the non-users. 66 % of the dietary supplement users took the supplements every day. The risk of excessive intake might be increased by trace elements in food plus that in dietary supplements.
