| Research Abstract |
Dietary supplements, suppliers claim their beneficent effect to certain physiological functions, should be examined beforehand for their safety and effects. We tried to work out an example of such functional test applying objective and valid methods that have been used for neurological evaluations especially in environmental sciences. Aimed supplement was docosahexaenoic acid (DHA), a kind of essential fatty acids we usually take from fish. A remarkable result was that, among persons taking DHA, there was tendency of decrease in tremor intensity as the serum arachidonic acid concentration increased.
