Vitamin D Supplements May Help Relieve Symptoms Related To Crohn’s


Research presented at Digestive Disease Week® (DDW) explores new methods for managing digestive health through diet and lifestyle.

Individuals suffering from Crohn’s disease are often plagued by reduced muscle strength, fatigue, and poor quality of life. These symptoms can remain even when patients are in remission. A randomized, double-blind, placebo-controlled study found for the first time that vitamin D supplementation corresponded to significant relief of these symptoms.

“These findings, to our knowledge, are the first to suggest potential benefits of vitamin D supplementation on muscle strength with corresponding benefits for fatigue and quality of life in Crohn's disease. However, they need to be confirmed in larger studies,” said Tara Raftery, research dietician and PhD candidate at Trinity College Dublin, Ireland.

The study found that after three months of taking 2,000 IU of vitamin D per day patient’s muscle strength, measured by hand-grip, was significantly higher in both dominant and non-dominant hands compared to those taking placebo. Patients also reported significantly less general, physical, and mental fatigue and a higher quality of life when levels of vitamin D were 75 nmol/L or more.
