Unless specified what level it's drivel... anything at "high" levels
can be toxic, even water.

Vitamins ideally should always be taken under the auspices of ones
medical professional... which suppliments and how much depend on
several factors, such as usual diet, blood work, age, weight, sex,
ones medications, etc. That said the typical one a day OTC
multi-vitamins don't contain enough of any one ingredient to be toxic
to the average individual, unless one has a particular medical
condition and/or is taking particular Rx meds they are safe...
everyone should have a complete physical once a year, that's when to
discuss suppliments.
