Overview

Doctor's Best Vitamin D3 5000 IU provides 125mcg of vitamin D3 (cholecalciferol) per softgel in olive oil for optimal fat-soluble absorption. The 360-softgel count provides a full year of daily vitamin D3 supplementation at approximately $0.04 per day — making this one of the most cost-effective D3 supplements available. Vitamin D3 is essential for calcium absorption, bone mineralization, immune function (activates T-cells), mood regulation, and muscle function. The 5000 IU dose is appropriate for individuals with documented deficiency or those living in northern latitudes with limited sun exposure.
