Depending on how much kidney function you have, your doctor may get you to take a vitamin D supplement or try to elevate your levels of calcium and phosphorus to increase your levels of vitamin D. Keeping levels of vitamin D, phosphorus, calcium and PTH within normal range may slow down the loss of kidney function. (See reference 1, guidelines 4.1 and 4.2.)

Sunshine is one source of vitamin D Find out what type of vitamin D is right for you. You usually get vitamin D from the sun and your kidneys convert inactive vitamin D to an active type your body can use. If you kidneys are damaged, this process will not work as well as it should, and you may have to take an active form of vitamin D. If you have low levels of vitamin D, get your doctor to tell you what type of vitamin D you need. (See reference 2.)
