No, eating over 100% of the Daily Value for a nutrient does not mean that you have to compensate by avoiding that nutrient on the following day. Your question is an excellent one, however, and I'd like to take the time to explain more fully how to interpret these percentages, including %DV.
When you get 100% of a nutrient's Daily Value, it means that you are getting enough of the nutrient to meet the average daily need for a generally healthy adult. "100% DV" means that there is enough of the nutrient to cover the general biochemical need for that nutrient in the human body for one day. It does not guarantee, however, that you have enough of the nutrient to meet your personal, individual needs. For example, there are many chronic health problems that deplete certain nutrients from you body. These problems would cause your body to need more than 100% DV as would the use of certain prescription or over-the-counter medications. The 100% DV guideline is simply a ballpark estimate that should get you thinking in the correct general category of nutrition. For example, if you only have 10% DV for a nutrient, you are highly likely to be getting an insufficient amount of that nutrient.
When you go over 100%DV, it simply means that you have provided your body with more than enough of the nutrient to meet your body's general biochemical needs on that day. Your body will decide what to do the extra amount. It may decide to eliminate it altogether, and so you will find it passing out of the body when you urinate or move your bowel. Your body may also decide to store the nutrient, either temporarily or for a longer period of time.
In general, we do not recommend going over approximately 200% DV for any particular nutrient unless you have some evidence to suggest that more than 200% is needed. Many healthcare practitioners go far over 200% DV in recommending nutrient intake to their patients, and many research studies show that even 1000% DV is sometimes needed to meet the body's needs. But unless you know what is happening inside your body from a biochemical and nutrient standpoint, large excesses can also be potentially harmful to your health. This is our reason for suggesting people stay, in general, within a 100-200% DV range, unless under the guidance of a licensed healthcare practitioner.
