Detailed Description:

This is a double-blind, placebo-controlled, randomised, parallel group trial in healthy male and fem ale subjects in regular employment. The duration of dosing will be 28 '(+/- 1)' days and assessments w ill be made on two visits (visits 2 and 3) with a training on the CDR system at the screening visit.

The subjects will receive one bottle with 35 tablets [of either Ginseng G115 40 mg, multivitamin, mu ltimineral '+' Paullinia cupana extract PC102 75 mg (Guarana) or placebo] from the pharmacy at the in vestigational site. The subjects should take the study drug from day 0 to day 28 '(+/- 1)' Subjects will be assigned to one of the two treatment groups randomly. The allocation ratio is 2:1..

Study Hypothesis:

H0: No difference exists between the treatment and the placebo groups in terms o f baseline-adjusted change in Power of Attention after 28 days and averaged over 4 and 6 hour time point. H1: A difference exists between the treatment and the placebo groups in terms of baseline-adjusted change in Power of Attention after 28 days and averaged over 4 and 6 hour time point. The null and alternative hypotheses for the secondary endpoints are set up accor dingly. The statistical testing will be carried out at the 0.05 level of signifi cance. The test will be performed two-tailed.

Comparison(s):

The comparator is a matching placebo film-coated tablet without active ingredien ts.
