would my body absorb a larger percent of the vitamins in a vitamin supplement if i drank more water?
The B-complex vitamins and C are water-soluble. There are a lot of vitamins that are fat-soluble and can be stored in the fats and fatty tissues of your body. Do not start experimenting with drinking more water than you need, as you may deplete electrolytes and throw off your body's balance.
If you take supplements, you will absorb more of what is in the supplement if you eat a little food when you take the supplement. For example, some crackers and a small glass of whole milk.
In general, you are much better off to eat a wide variety of foods and to consider a multivitamin-mineral supplement as insurance. Rather than as a primary source of micronutrients.
