Vitamin D supplementation in adolescents with irritable bowel syndrome: Is it useful? A randomized controlled trial.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

Vitamin D deficiency is common in irritable bowel syndrome (IBS).

There is growing interest in the role of vitamin D in pediatric IBS.

The researchers aimed to evaluate the effect of vitamin D supplementation in adolescents with IBS and vitamin D deficiency.

Who Took Part

By PubMed's age tags, the people studied were teenagers, both men and women.

Vitamin D status as well as different IBS score systems (IBS-SSS, IBS-QoL, and total score) were evaluated before and 6 months after treatment.

How the Study Was Run

In design terms this was a randomized and placebo-controlled study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

The comparison arm used a placebo, so changes seen with Vitamin D, K2, Magnesium and Zinc could be set against what happens without it.

One hundred and twelve adolescents with IBS and vitamin D deficiency were randomly divided into two groups of matched age and sex.
