Does Systematic Use of Small Doses of Vitamin D Have Anti-Inflammatory Effects and Effectively Correct Deficiency Among Healthy Adults?
Article in Nutrients, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCalcitriol, beyond its well-established role in calcium and phosphate homeostasis, contributes to immunological processes. No known vitamin D dosage regimen effectively corrects the deficiency while accounting for immunoregulatory effects. Therefore, the purpose of this assessment was to determine whether regular administration of low doses of vitamin D might correct deficiency and have immunoregulatory effects.
methodsA total of 35 healthy volunteers were asked to supplement with vitamin D daily at a dosage of 500 or 1000 IU, depending on the degree of deficiency, for 12 months. At the beginning of the study and after the end of the supplementation period, concentrations of 25(OH)D; PTH; total calcium; inorganic phosphorus; and the inflammatory cytokines IL-17, IL-10, TGF-β, and IFN-γ were determined in all participants.
resultsCorrection of vitamin D deficiency was achieved with accompanying decreases in PTH and pro-inflammatory cytokine concentrations, while the concentration of anti-inflammatory cytokines remained stable.
conclusionsTherefore, regular vitamin D supplementation, even in small doses, effectively corrected the deficiency and had immunomodulatory effects.
