You could take 5x most multivitamins and never get close to over dosing. The recommended doses are minimum, not maximums. For instance vitamin D is often quoted as 200 IU/day and may cite 400IU as an absolute maxium. But a single day in the sun sitting in your bathing suit and your skin will make 10,000 IU, a factor of 50x more. Recent research puts the toxic level at 40,000 IU/day but only if you take that for months. The elderly and babies are sometimes given shots of vitamin D of 100,000 to 300,000 IU.
The truth is: very little research has been done on vitamin doses and most recommended levels are not based on real research but ultra conservative guesses.
