Just a question, and no offence intended, and im sure youv answered this question before, but why so many vitamins and minerals? If you are eating a wide range of fruits and veges, meats etc, many of these are not needed. Excess doesnt mean better performance.
some vitamins do have toxicity levels for excess doses, so just make sure you fall under the high level doses. Its not common to have toxicity issues, but excess supplementation can cause this.
