Zinc deficiency is a common finding in patients with atopic dermatitis (eczema). This study investigated whether supplementing with zinc would have any impact on the condition. After 8 weeks of zinc supplementation in patients with low zinc levels, hair zinc levels increased significantly, along with improvements in EASI scores, TEWL, and visual analogue scales for pruritus.
