Vitamin D Supplementation Does Not Improve the Severity or the Resolution of Ultraviolet B-Induced Acute Erythema.

What Was Tested

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

To study the effect of oral vitamin D on UVB-induced erythema and its resolution in fair-skinned subjects.

Why It Was Studied

Whether vitamin D supplementation alleviates the severity of ultraviolet B (UVB)-induced erythema and/or facilitates its resolution remains undetermined.

Who Took Part

The abstract describes 50 volunteers taking part.

The age groups tagged for this paper are young adults, both men and women.

How the Study Was Run

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

It is described as a pilot, a small early test of whether a larger Vitamin D, K2, Magnesium and Zinc study would be practical.

Resolution of erythema in both groups was assessed by chromametry 24, 48, and 72 h after vitamin D administration.

What Was Measured
