vitamin k

I like to know what do you believe about taking vit k. Some doctors said to us not to take it, others to take it for osteoporosis. My daughter is 19 years old.
Thank you for this question. Vit K is important for production of blood clotting factors in the liver and may be a factor in CF related bone disease. Vit K supplementation (particularly if deficiency can be described) is therefore a reasonable approach and is supported by European guidelines. However it is important to note that the European guidelines indicate that Vitamin deficiency may be rare and so routine supplementation is controversial but should be considered in patients with low bone mineral density, liver disease or a prolonged prothrombin time. I recommend you discuss in further detail with your CF doctor whether it would be appropriate for you take Vit K supplements.

Good luck
