Overview
Doctor's Best Vitamin D3 5000 IU provides 720 softgels — nearly a 2-year supply — at under $18. That's approximately $0.025 per day, making this the most cost-effective high-dose vitamin D3 on the market. Each softgel provides 5000 IU (125mcg) of vitamin D3 as cholecalciferol in olive oil for fat-soluble absorption. The 5000 IU dose is the most commonly recommended by integrative physicians for maintaining optimal blood levels (40-60 ng/mL) in adults with insufficient sun exposure. Doctor's Best uses a small, easy-to-swallow softgel format.
