How can vitamin supplements help people with cystic fibrosis (CF)?

Vitamin supplements can help people with cystic fibrosis (CF) get enough vitamins so their bodies work properly. Taking extra vitamins helps replace the ones they are unable to get from food.

The vitamins people with CF are most likely to need are vitamins A, D, E and K. These are called fat-soluble vitamins because they get absorbed into the body along with fat. People with CF don’t have enough of these vitamins because they can’t get enough fat into their bodies to absorb them. A dietitian can help people with CF find the vitamins they need.

People with CF might also need extra salt in their diet. Usually, people get enough salt from their food and by using a salt shaker at meals, but there are two reasons why people with CF might need even more. The first reason is if they do lots of exercise that makes them sweat. The second reason is if they live somewhere very hot and dry and the weather makes them sweat. A dietitian can help people find drinks that have extra salt in them.
