                                A 2011 meta-analysis concluded that cholecalciferol (Vitamin D3) is more effective at raising serum vitamin D levels than ergocalciferol (Vitamin D2). While both are forms of vitamin D, understanding the core distinction between ergocalciferol and cholecalciferol is crucial for making informed choices about nutrition and supplementation.
