Absolutely not. There are two types of vitamins. Fat soluble vitamins: A, D, E, and K. The other type of vitamins are water soluble vitamins, such as vitamin B. In water-soluble vitamins, your body absorbs what it needs and the rest of it is basically expensive pee.
However, because fat soluble vitamins are stored within the fat cells, you can accumulate a toxicity of a certain vitamin. For example, too much vitamin A can cause vision problems such as blurriness.
So, as with most substances we put into our bodies, moderation is the key. Your original question? No; there is a limit on the amount of vitamins we need. The more the better is not the answer.
