According to the Physicians Desk Reference, only 10-20% of vitamins and minerals in a pill form are absorbed by the body. Even those pills listed as "all natural" often have added fillers and coatings that inhibit absorption. Nutritional drinks offer a 98% absorption rate because they bypass the digestive process and go directly into the bloodstream and into the cells within a matter of minutes.

The Physician's Desk Reference shows that vitamins and minerals in pill form are only 10 to 20% absorbed by the body. That means for every $100 you are spending on nutrients, you are literally flushing about 90% of it down the toilet. Because of this lack of absorption, companies must use mega does of nutrients and this can cause a taxation on the kidneys. According to the National Advisory Board, 100mg consumed in a tablet form translates into a minute stabilized 8.3mg concentration in the blood.
