For vitamin D3 softgels, choose a product whose exact label identifies D3 and the softgel format. The 2,000 IU D3 softgel listing is one example to compare by serving information and container count. Combination products may include additional nutrients or oils, while another vitamin softgel can have a different composition entirely. Check all ingredients and the full labeled serving rather than comparing package counts alone.View Vitamin D3 – 2,000 IU (100 Softgels).
