Based on a study in 1968, a 2000 calorie diet should have certain levels of essential ingredients. These can be found on food labels on almost every retail food product available.

What I could not determine was whether or not the daily values on the labels are suggested as minimum (you should have at least this much per day) or maximum (do not exceed this much per day).

Consider even two very common vitamins. Vitamin A, suggested daily value 5,000 IU (International Units) and Vitamin B12, suggested daily value 6 micrograms.

As Vitamin A is fat soluble, overdosing has serious implications. On the other hand, Vitamin B12 is water soluble, and can pretty much be taken at any dose without any side affects.

Is the suggested daily value a minimum or a maximum amount?

Sorry, but the rule on nutrition is: if the question is about how food affects your body and your health, it is off topic here. –  rumtscho Jul 7 at 23:23
