Evidence Map

What The Sources Report

• Studies on vitamin D have increased tremendously since the vitamin D receptor VDR has been identified in the whole immune cell population, including macrophages, dendritic cells (DCs), T cells, and B cells. [Shende Sandesh (2026); evidence level 3]
• Vitamin D was historically confined to skeletal biology, primarily associated with calcium-phosphate homeostasis and the prevention of rickets, osteomalacia, and osteoporosis. [Shende Sandesh (2026); evidence level 3]
• More than two billion people are at risk of micronutrient deficiencies, which often involve multiple, rather than single, nutrients. [Muacevic Alexander (2026); evidence level 4]
• They are widely used to help individuals meet their daily nutrient requirements, support overall health, and address increased nutritional needs associated with pregnancy, aging, and illness. [Muacevic Alexander (2026); evidence level 4]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation
