Vitamin
Substances that are essential in small quantities to our nutrition; they act especially as substances involved in the regulation of metabolic processes but do not actually provide energy by themselves. They are usually present in natural foods, or are sometimes produced within the body. Since CF patients have a hard time absorbing fats in their diet, they cannot effectively absorb vitamins that are fat-soluble. Therefore, these vitamins (A, D, E, and K) must be given as a separate vitamin supplement on a daily basis. Once yearly, the blood levels of these vitamins are checked to ensure patients are getting the amount of each vitamin
