This article is a good example of the arrogance around nutrition. A third possibility is that we don't know enough to be able to manufacture vitamins in a factory. When one eats un-manufactured food * for a given nutrient there are many different forms of it * there are many inter-related nutrients that effect each other (nutrient synergy) Take a look at how many forms of Vitamin A there are on the Wikipedia entry. The idea that we can pick one and load up on it may not be correct. This is true of many minerals also because they need to be bound with something else (magnesium malate, etc). The odd thing about nutrient synergy is that it is very well established scientific phenomenon. But it just doesn't fit well with our reductionist approach to science.
