Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin D3 has some scientific evidence supporting its use in the management of eczema (atopic dermatitis), although this evidence is still considered preliminary and not definitive. Research suggests that individuals with eczema often have lower serum levels of vitamin D compared to healthy controls. Vitamin D plays a role in modulating the immune system and maintaining the integrity of the skin barrier, both of which are relevant in eczema's pathophysiology.

A number of small randomized controlled trials and observational studies have investigated oral vitamin D supplementation in patients with eczema. Some of these studies have shown modest improvements in eczema severity, particularly in children and in cases of winter-related flare-ups. For example, a 2016 meta-analysis in Pediatric Allergy and Immunology found that vitamin D supplementation was associated with significant improvement in eczema symptoms in children, especially those who were vitamin D deficient. Another study in adults demonstrated some improvement in disease severity scores with supplementation.

However, the quality of evidence is variable and there are studies that show no significant benefit. Moreover, expert guidelines do not universally recommend vitamin D supplementation for eczema unless a deficiency is documented. Overall, while there is biological plausibility and some positive clinical data, the evidence base is not yet strong enough to recommend vitamin D3 as a primary or stand-alone treatment for eczema. It may play a supportive role, particularly for those with low vitamin D levels.
