The minimum daily requirement is not the same as the optimum dose for good health. For instance, consuming no vitamin-C will give you the disease “scurvy”, and the minimum daily dose will keep scurvy away, but…for optimum health, you must take much more than that.
In fact, if you are an adult and you are a little sick, take a 500mg pill every four hours that you are awake (sleeping 8 hours). I think FDA says 90mg a day is enough to keep scurvy away? Even when I am not sick, I take 500mg twice a day.
