We aimed to discover how vitamin D3 supplementation affects chronic spontaneous urticaria, commonly known as hives. In a well-structured study, 80 participants were randomly assigned to receive either low (4200 IU/week) or high (28,000 IU/week) doses of vitamin D3 over 12 weeks.
Our findings were encouraging. Both groups showed a significant reduction in the severity of their hives, but those taking the higher dose experienced even greater improvements. After just six weeks, the high-dose group reported notably lower severity scores compared to the low-dose group. By weeks six and twelve, quality of life ratings also significantly improved, particularly for those receiving the higher dosage.
We observed that levels of 25-hydroxyvitamin D, an important marker for vitamin D in the body, rose significantly in both groups, with the high-dose group showing a much greater increase. Although the reduction in medication use was significant for all, we didn’t find any notable differences between the groups in this regard. Interestingly, we did not see any strong links between positive skin test results or specific antibody levels related to thyroid function and a positive response to vitamin D treatment.
Overall, adding vitamin D3 at a higher dosage appears to be a safe and potentially effective approach for managing symptoms associated with chronic hives.
